what is oikawa's nephew's name?

He is one of Ikkei Ukai's students at his volleyball school. He quickly becomes friends with Hinata when the teenager joins the school. After the Spring High begins, Yū often accompanies his teacher and several other students to Karasuno's games and cheers on Hinata while chatting with Yachi. [He shared his Japanese voice actress as Kaori Suzumeda, and he shared his English dub voice actress as Hana Misaki and Ryūnosuke Tanaka (young).]

A middle school student and the older brother of Yū. He is one of Ikkei Ukai's students at the Lil'Tykes Volleyball Classroom and plays as a setter.

Taku Sugano, Rintarou Hoshi and Riku Ogata are the other grade-schoolers that, like Yū and Hiroki, are Ikkei's students. [Hoshi shared his Japanese voice actress as Takeru Oikawa and Machiko Onodera, and he shared his English dub voice actor as Kazuteru Akiu, Masaki Gōra (season 2), Yoshiharu Haga, Yumeto Nagamatsu, Rintarō Numajiri, Sōma Oyasu, and Kōji Sekimukai.]

He appears to be a long time and avid fan of Karasuno's Boys' Volleyball team. It is said that he will cheer for the plays he think are good, and boo the bad ones. The current Karasuno third years remember him coming to watch their games during their first year and calling the team fallen crows. Yokoyama is seen cheering for Karasuno ever since the Shiratorizawa match.

She appears very caring and supportive of her sons, even making custom bento lunches for Akiteru for volleyball practices. (She shared her Japanese voice actress as Yukie Shirofuku.)

An alumni of the volleyball club, Tokita's debut and only appearance comes when he meets with Narita and Kinoshita just before the match against Schweiden Adlers and the MSBY Black Jackals. His excitement for the match is clear as Yaotome states that he and the others would not miss the chance to watch Hinata and Kageyama play against each other.

Presumably part of the next group of volleyball players that joined the team after the events of the Spring Tournament. He accompanies Tokita and Yaotome to the match between the MSBY Black Jackals and Schweiden Adlers and meets with Narita and Kinoshita.

Yaotome joins Tokita and Shoji in attending the match between the Schweiden Adlers and MSBY Black Jackals. The three meet with Narita and Kinoshita just before the match starts. Although his position in the club is never made clear, it is possible Yaotome was the libero as he is seen in one of Hinata's flashbacks wearing the libero jersey[1].

Madoka Yachi's co-worker whose name is never revealed. He appears to be a close co-worker of Madoka as he at times arrives to her house to walk with her to work. From this, he is able to see how Madoka tries to get her daughter to be a stronger person but finds that Hitoka may actually get her timid nature from her mother's criticism. [He shared his English dub voice actor as Michinari Akagi, Jingo Fukiage, Yutaka Obara, and Morisuke Yaku (season 2-present).]

The mother of Shōyō and Natsu Hinata. She appears to be a young looking woman with short black hair she keeps in a bob style. While not much is known about her, Hinata's mother appears to be a caring and supportive mother. She is well aware of her son's love of volleyball and the things he does in order to keep playing; such as putting in extra study time to pass exams and the practices he does at home. Although she has made very few appearances in the manga, she is never seen in the anime. [She shared her Japanese voice actress as Tetsurō Kuroo (young) and Saeko Tanaka.]

Yoshida is a third-year student at Karasuno High and member of the soccer team. He has short black hair and long, black eyebrows. His only appearance in the series is when Karasuno is having their annual sports festival. He appears next to Sugawara to brag about how his teams second-years will give the members of the volleyball team a hard time but was soon proven wrong when he and everyone else witnessed Hinata and Kageyama begin racing each other instead of the other racers.

Oujiyama is a second-year student at Karasuno High and the ace player of the tennis club. Oujiyama is shown to be quite attractive and is very popular among the female students. During the school's annual sports festival, his team had a slight lead in the relay race. He took advantage of this to be admired by the many girls cheering him on but this allowed Tanaka to quickly close the gap and take the lead.

A member of the Nekoma Girls' volleyball team who attends the match between Nekoma and Karasuno. She helps explain Kenma's reach over tactic to fellow students who were unsure of what occurred during the play.

The unnamed mother and father of Kenma Kozume. Since Kenma's childhood, both have acknowledged that their son is highly interested in video games. Despite this, Kuroo has pointed out that they are mindful of how much time Kenma spends on games when he states that they were forced to take his games away for a while when they discovered he was playing games very early in the morning[2]. When Kenma and Kuroo were still young, Kenma's father would ask why Kuroo would not invite Kenma to join him and other kids in playing soccer but accepted how mindful Kuroo was about not wanting to make Kenma do something he didn't want to if he was not interested.

She is one of the girls who had come to cheer Aoba Johsai, especially Oikawa, during the Interhigh Preliminary. Throughout the match, she shows that she isn't too familiar with the rules and plays of volleyball and relies on Takinoue and Shimada to explain things to her and Ujiie. When Karasuno lost the Interhigh match, she claps for Karasuno. She would later appear during Seijoh's rematch against Karasuno.

She is one of the girls who had come to cheer Aoba Johsai, especially Oikawa, during the InterHigh Preliminary. Just like Hirama, she attended the volleyball match to cheer Aoba Johsai on but can be seen at the end of the match clapping alongside her friends when Karasuno bows to their spectators. She later appears during the Seijoh vs Karasuno rematch.

Not much is known about this man, other than that he attended the Aoba Johsai vs. Karasuno match at the Spring High Preliminary to support Kyōtani. He was fundamental to the development of Kyōtani's character, as he was the one who had influenced the boy to cooperate with his teammates and face each other head-on if he wanted to perform at his best. Kiyoshi's words prove to be useful as when Kyōtani placed his trust on his team, they were able to spike successfully past their opponents. (He shared his English dub voice actor as Takanobu Aone and Iori Kanazawa.)

He is Oikawa's nephew who attends volleyball classes at Lil'Tykes Volleyball. He appears to be an energetic young boy who is not afraid to state the obvious, even if it embarrasses his uncle. (He shared his Japanese voice actress as Rintarou Hoshi and Machiko Onodera, and he shared his English dub voice actress as Minaho Ono and Kaori Suzumeda.)

A third-year wing spiker from Aoba Johsai High. Yuda appears to be of a shorter height compared to his teammates with a thin build. He has short, light brown hair with matching eyebrows, brown eyes, and appears to have freckles. Yuda had attempted to cheer up his teammates after they lost to Karasuno in the semi-finals. Although he was overwhelmed with his own emotions, his state did put some of the third-years in a better mood. Afterwards, he joined the team in getting ramen and then accompanied the third-year players to the gym for a game. Like the others, he would be moved to tears when Oikawa thanked them for being together the last three years.

Sawauchi is a third-year middle blocker from Aoba Johsai High. Sawauchi is of average height with messy black hair and small, thin eyebrows. While he did not play with the rest of the team, he did join others in supporting them at matches. After Seijoh lost in the semi-finals, Sawauchi had to help keep Yuda back after he became overly emotional in trying to comfort the starting third-years. He accompanied the team to the ramen shop and later joined them in a short game at the gym. When Oikawa thanked the third-years for the time they spent together during high school, Sawauchi began to cry.

Shido is a third-year wing spiker from Aoba Johsai High. Shido has brown hair that reaches the bottom of his ears. He has small, thick eyebrows and small pupils. Shido was one of a few third-years that was part of the volleyball team but did not take part in any matches. He did join Seijoh supporters in cheering for the team during matches. He and Sawauchi would have to hold Yuda back when he tried to cheer the team up after they lost in the semi-finals. He stays with the team when they go to the ramen shop and then played a game with them at school. Like the team, he would begin crying when Oikawa thanked them for the last several years.

The unnamed mother of Tōru Oikawa and grandmother of Takeru Oikawa. She is shown to be a young woman who shares a close resemblance with her son. Her only known appearance is during a flashback when Oikawa reveals to Hinata that, during his childhood, he had obtained Jose Blanco's autograph on an unused jockstrap and she had mistakenly washed it with the laundry. She apologized for the mishap and tried to assure her young son that the autograph was still legible but Oikawa was still distraught.

Jin is Shiratorizawa's vice-captain and wears the number two jersey. Despite being the vice-captain, he is not a regular.

Both he and Reon Ōhira are listed as vice captains of the Shiratorizawa Volleyball Club.

Yunohama is one of Shiratorizawa's pinch servers and wears the number 7 jersey. He is a second-year and played in the match against Karasuno during the Spring High. He was later present during Ushijima's speech to his underclassmen before retiring. His main weapon is the jump float serve. [He shared his English dub voice actor as Kenrō Fukatani, Yasushi Kamasaki (season 2-present), Tatsuya Mori, Takurō Oiwake (season 1), and Tatsuki Washio (season 2).]

The wife of Tanji Washijō. Terano appears to be an easy going and cheerful woman. She first appears when joining her husband during the match between the Adlers and Jackals. Like Tanji, she finds enjoyment in watching Ushijima play. She is seen meeting the former Shiratorizawa ace after the match and is last seen watching the television program where he meets with Tendō in Paris.

Umeda is currently a second-year student at Shiratorizawa Academy. He is taller than average with a medium build. He has black hair that he keeps styled upward, long eyebrows, and small pupils. His position on the team is currently unknown. After Shiratorizawa lost in the finals of the Spring Tournament Qualifiers, Ushijima addressed each player with advice of how to improve themselves and the team. Umeda was given the advice to become more consistent with his form and to not get through practices doing what he wished.

Shibata is currently a first-year student at Shiratorizawa Academy. He plays on the boy's volleyball team as a wing spiker but is not one of the starting regulars. Shibata has short, messy dark hair with thin eyebrows. He also appears to be slightly taller than average.

The mother of Wakatoshi Ushijima and ex-wife of Takashi Utsui. She has a close resemblance to her son. Her hair is dark and kept short with a slanted edge and her bangs neatly combed from her face. She had been married to Utsui when he married into the Ushijima family. When Ushijima was still young, she had wanted to train him to become right-handed since being left-handed was not a trait that normally ran in her family. However, Utsui managed to get her not to go through with this change by giving up his rights in family matters and stating that being left-handed could be Ushijima's greatest blessing. Some time later, she and Utsui divorced.

He is a third-year student at Johzenji High and was the captain of the boys' volleyball team before retiring after the InterHigh. Okudake appears to have had a good friendship with Hana Misaki as he is seen giving her advice of how she can help the team become more focused. He also seems to have been close with Yūji Terushima whom he tried to help understand that not all situations will be fun and exciting but left a good impression with his junior as a solid foundation. [He shared his English dub voice actor as Takurō Oiwake (season 2-present) and Yūki Shiroishi.]

Mother to Kōrai and Akitomo. Asa shares physical similarities to her younger son, Kōrai. She has the same large eyes and light colored hair. She is on the shorter side which appears to be where Kōrai inherited it from. Asa is a firm but supportive mother to her sons. She appears to have been closer with Kōrai during his childhood. She helped him understand that he shouldn't worry about his height and instead find other ways to be better than those who are taller than him.

The older brother of Kōrai Hoshiumi. Akitomo is rather tall with short, dark hair, and large eyes similar to his younger brother and mother. Because of his height, he is seen playing basketball as early as the fourth grade. When they were younger, Akitomo would often make fun of Kōrai for being so short. He appears to be naturally talented in sports as he was seen spiking a volleyball on his first attempt. Although he often picks on Kōrai, the two appear to have a natural sibling relationship.

Father of Kōrai and Akitomo and husband of Asa Hoshiumi. He is a very tall man and has the same dark hair as Akitomo. His only appearances come in flashbacks of Kōrai's childhood when he first became interested in volleyball. While his name is never revealed, Kōrai's father appears to be a friendly and caring person.

He is currently a second year student in high school. Height: 174.2 cm, Weight: 63.3 kg. Okuda is always seen with Takanashi together watching the matches at the Spring Interhigh. He used to be a volleyball player in middle school and is well aware of the basics. He wore the #5 jersey.

She is currently a second-year high school student. Takanashi was a former volleyball player who retired after middle school. Height: 159.5 cm, Weight: 47.5 kg. Takanashi is always seen together with Okuda watching the matches at the Spring Interhigh. She is revealed to be a fan of the Miya brothers but says she is starting to become a Karasuno fan after watching their match. She also expressed interest in possibly returning to volleyball. She wore the #2 jersey.

Ōnoya comes to observe Karasuno's match against Ohgiminami and Kakugawa during the Spring Interhigh preliminary rounds. He is well acquainted with Ikkei Ukai and cheers on Karasuno along with the rest of the supporters. He appears to be quite supportive of the Karasuno team as seen when he defends them when Mikako doubts their chance of winning against Kakugawa.

Mikako is a teacher and the volleyball team advisor for an unstated middle school. She is also a neighbor of Gengorō Takahashi. She shows up to watch the match between Karasuno and Kakugawa and is shown to cheer for the shorter underdog team due to having shorter players on her own team. Later, she is surprised to find Hinata scoring so many points while going against the two-meter Hyakuzawa.

Blanco is currently the coach for the Argentina Men's Olympic Volleyball team and had previously coached the Tachibana Red Falcons. Several years earlier he had met Oikawa as a child and became his inspiration for being a setter. During that match Oikawa observed, Blanco was said to be a setter who helped the team ace get back on track through easy to hit sets[3]. He was later able to help Oikawa when he was feeling upset about others being more talented than him even though he could tell that Oikawa just wanted to meet with him again. Blanco would later become Oikawa's coach when he became part of the men's Olympic team.

Yamazaki was a third-year at Kiyokawa High School. He was the Boys' Volleyball Club's captain and ace. Yamazaki is a tall young man with short, sandy blond hair and long dark blond eyebrows. He is seen making repeated attacks during the first round match against Nekoma. However, despite having good stamina and a variety of attacks, he would quickly be worn down by Nekoma repeatedly making receives on his attacks.

Yamazaki is also the only known Kiyokawa High player. His team's other members' names are still unknown.

A beach volleyball player in Brazil. Gabriel and Gino make up the famous 'Buy me a Beer' brothers. The two are well known for challenging others in order to win free drinks. Gabriel's debut comes when he and Gino challenge Hinata and Oikawa to a game. Initially, Gabriel believed Oikawa to be a fearsome opponent when he attempted a jump serve until the wind ruined it, leaving Gabriel and Gino to laugh at Oikawa's misery. The two win the match against Oikawa and Hinata, who buy them drinks afterwards. Later, they play the Japanese men again but this time lose and buy them dinner. During the Olympics, Gabriel and Gino are watching the Japan vs Argentina men's volleyball match and spot Hinata and Oikawa during the broadcasting.

A native of Brazil and teammate of Gabriel. Gino first debuts when he and Gabriel challenge Hinata and Oikawa to a game. Being well known for challenging tourists to games in order to obtain free drinks, Gino and Gabriel have earned the nicknames 'Buy me a Beer' brothers. Seeing Oikawa attempt a jump serve, Gino first thought that Oikawa would be a challenging player until it became clear that he was not used to the elements of beach volleyball. This results in Gino and Gabriel easily beating the Japanese men and getting their beers afterwards. The two later play against Hinata and Oikawa again but this time they are defeated as the two were able to quickly adapt and improve. During the Olympics, Gino and Gabriel are watching the live broadcasting of the match between Japan and Argentina and spot Hinata and Oikawa.

The young son of Nicollas Romero. Rubens is revealed to be a big fan of Hinata's and has been stated to want to start playing beach volleyball because of him[4]. Rubens is seen at the end of the match between the Schweiden Adlers and MSBY Black Jackals when he joins his father in approaching Hinata as he vows to not be defeated by him in the future. At this point, Romero would ask Hinata to be in a picture with his son. However, Rubens would suddenly become shy at meeting Hinata.

A student from Yukigaoka Junior High and member of the tennis club. When Hinata was first starting out with volleyball and was seeking others to help him practice, Junpei was one of the people he turned to in seeking help for practice. With Hinata agreeing to help Junpei with his own practice, the tennis player noticed Hinata's lack of skill but did point out how Hinata has superb reflexes. Upon hearing how Hinata tends to freeze when he realizes the ball is heading his way, Junpei teaches Hinata the Split Step technique; a maneuver in which the player will disconnect their feet from the ground in order to reset their form and use the momentum to go into the next move as well as perfecting their overall reaction time once timing is perfected. Hinata would later utilize this method during the First Year Training Camp.

He is a former All-Japan setter. Inuhata first appears when he is shown to have coached a volleyball camp that the Miya twins and Aran attended when they were still in grade school. Although Atsumu wasn't originally thrilled that he was a setter, Inuhata would soon unintentionally inspire him to think setters are the better position when the then young Atsumu hears Inuhata say how he will give the spiker an easy to hit set. Years later, Inuhata would reappear as an announcer during the match between the MSBY Black Jackals and Schweiden Adlers[5]. (He shares his Japanese voice actor as Yūto Kosaku and Kikutaro Masumoto.)

A university coach that makes occasional appearances through the series although his name is never revealed. He first appears during Karasuno's practice match when Yachi was first brought to the club. During the match, he was impressed with Karasuno's individual and team plays. He would later appear during the First Year Training Camp at Shiratorizawa Academy. He is fairly surprised that Washijō was allowing Hinata to stay during the camp as it is well known that the elderly coach has no interest in short players. He expresses how it seems a waste to have Hinata be a ball boy and admits that he would train the middle blocker to be a wing spiker after seeing tapes of matches he had previously been in and recognizes his potential.

Masumoto currently works for the Japan's Volleyball Association Tournament Operation Department. Masumoto makes a few appearances during the Spring Tournament and the Final Arc. Usually, he is seen in the company of Coach Fuki Hibarida. (He shares his Japanese voice actor as Masahiko Inuhata and Yūto Kosaku.)

Lucas Santos is a veteran beach volleyball player. He stands at 181cm and specializes in defense and attacks. He has dark hair with a matching beard and appears to be easy to get along with. As a seasoned beach volleyball player, he shows great strategy during the Solcard Cup when he and his partner willingly picked the bad side of the court so that they could have the good side by the end of the match. Santos and Carvalho won the match in the end and would also witness when Nice proposed to Heitor but were confused at what was going on.

Carlos is a young man with light colored hair that reaches just under his chin and stands at 192cm. He is partners with Lucas Santos for the Solcard Cup. Thanks to his taller height, Carlos specializes in blocks but is also quite skilled with serves. Carlos and Santos would win the match against Hinata and Heitor. He would also witness when Nice would propose to Heitor and, although he aided in the cheers, he was confused by what was going on.

Hinata's beach volleyball coach in Japan. While coaching Hinata, he helped him understand that playing on the beach would be different because playing on sand is incredibly different from playing on a solid court. Takahashi instructed Hinata that he would need to stomp onto the sand in order to maintain his jumping abilities.

Kane first appears during a flashback Shirabu has during Shiratorizawa's match against Karasuno. Kane is revealed to have attended Toyokuro Junior High along with Shirabu and Shunki Kawatabi. It was while watching Kitagawa Daiichi play against Shiratorizawa that Kane heard Shirabu declare that he would attend Shiratorizawa Academy in order to play with Ushijima and witnessed how Shirabu became even more dedicated to his studies in order to pass the entrance exam. During the match against Karasuno, Kane is amused but seemingly not surprised that Shirabu kept his promise of attending Shiratorizawa and is now the one setting for Ushijima.

He is Oikawa's nephew who attends volleyball classes at Lil'Tykes Volleyball. He appears to be an energetic young boy who is not afraid to state the obvious, even if it embarrasses his uncle.

For the majority of the series, he was a third-year student at Aoba Johsai High, serving as the captain and setter for the school's Boys' Volleyball Team. He is the main antagonist of the Interhigh and Spring High Preliminary Arcs.

As of the Final Arc, he is a setter for Club Atlético San Juan, a professional team in the Argentine Volleyball Federation. He obtained Argentinian citizenship and plays on the Argentina National team as the starting setter.

Oikawa has dark brown hair that is swept outwards and eyes of the corresponding color. Many people find him attractive, to the point where several girls follow him around. Oikawa frequently smiles or grins, although Iwaizumi notes that these expressions are rarely genuine. He tends to make victory signs or large waving gestures, which are often accompanied by broad smiles or a wink. Another trademark expression of his is sticking out his tongue while smiling and winking.

Oikawa is of decent height for a volleyball player, standing just over six feet. While on the court, Oikawa wears the standard aqua and white Aoba Johsai High uniform emblazoned with the number one. He also wears dark gray athletic shoes with blue details. He wears a white kneepad on his right leg, contrasting with the black one worn on his left and by the other players in the series. At other times, Oikawa dresses in the Aoba Johsai uniform, which consists of khakis with dark brown detailing, a cream-colored vest, a dark red tie, a lavender button-down shirt, and a white blazer. During practices, he wears an aqua shirt and white shorts. During the finals match between Karasuno and Shiratorizawa, Oikawa is shown to wear glasses but it's unknown if he truly needs them or not.

Post-timeskip, Oikawa appears mostly the same although his hair is noticeably shorter, and he has developed a slightly more muscular build.

Despite his flirtatious nature (which makes him famous amongst female students, much to Tanaka and Nishinoya's envy) and childishness, Oikawa is an excellent, well-rounded player and is extremely serious about volleyball. He's known to have a "disgusting personality" amongst both opponents and his own teammates because of his smug and outwardly flippant attitude. Oikawa also frequently makes cheerful remarks but follows up with serious or intimidating afterthoughts. He is extremely intelligent and cunning and easily figures out both his teammates' and opponents' weaknesses.

However, on more than one occasion, Oikawa has been very attentive and caring towards others, but this is mostly seen with his teammates or people like Hinata while in Brazil.

Oikawa is ambitious and one-track-minded, but it's shown that he also has feelings of inferiority towards those he deems as naturally better than him, such as Ushijima and Kageyama. This is one of the main reasons he is known to push himself so hard. Oikawa also holds a grudge against Kageyama, whom he mockingly calls Tobio-chan. This is due to his feelings of inferiority surfacing when compared to Kageyama, who has been hailed as a genius setter since their time spent at Kitagawa Daiichi. Kageyama and Ushijima can also unintentionally bring out the more childish or rash aspects of Oikawa's personality.

To match his ambition, Oikawa works extremely hard and often endures vigorous solo practices after his normal practices with the team. In addition, Oikawa spends time at home watching past games of his rivals in order to observe their movements and patterns ahead of time, and strategizing how to defeat them. Despite that, he still takes time off on Mondays for rest.

It was seen post-timeskip that Oikawa has had thoughts of giving up on volleyball, but whenever that thought occurs, something really fun comes along to remind him why he loves it so much. Showing that while he has seemingly endless ambition, he does occasionally have doubts, though they never overwhelm him.

Since childhood, Oikawa is shown to have been heavily involved in volleyball. He was occasionally shown watching matches on television or playing the sport with Iwaizumi when they were still kids. When he was a little older, Oikawa and Iwaizumi attended a match between Japan and Argentina where Oikawa would become inspired to become a setter after seeing how the Argentina setter, Jose Blanco, was able to help the ace player get back on his game when he had started struggling during the match[1].

After this interaction, Oikawa is seen investing himself more into volleyball and appears to have been trying jump serves since he was young. Because of the time he put into his abilities, Oikawa was said to have been a highly skilled player by the time he began attending Kitagawa Daiichi. However, Oikawa began to struggle when his team began playing against Shiratorizawa Junior High and it was in particular playing against Ushijima that caused Oikawa distress and the start of his rivalry with the Shiratorizawa ace.

This only became worse when Tobio Kageyama began attending Kitagawa Daiichi and almost instantly started to gain more attention than Oikawa thanks to his higher skill set, natural athletic abilities, and being labeled as a prodigy at such a young age. Aware that Kageyama could potentially surpass him, Oikawa began behaving poorly toward the younger setter and constantly refused to teach him any new skills. After nearly striking Kageyama in a blind rage, Oikawa was able to get back on track thanks to help from Iwaizumi. This led to him being able to better focus his plays to bring out the best of each of his teammates and was eventually able to help Kitagawa Daiichi place second in the middle school tournament after Shiratorizawa. At the same time, Oikawa received the Best Setter Award and soon after would join Aoba Johsai.

During the practice match between Aoba Johsai and Karasuno, Oikawa did not appear until the third set. He instantly gained the admiration of the female students that were present which caused Tanaka to instantly hate Oikawa. Before Oikawa joins the game, Kageyama admits to his team that he learned how to serve and block just by watching Oikawa and it is because of this that he is dubbed "The Great King" by Hinata.

When Karasuno is at match point, Oikawa is subbed into the game and instantly targets his serves to Tsukishima. From having watched during his warm-ups, he was able to tell that Hinata and Tsukishima were not strong when it comes to receiving and would therefore be the weaker players to target. This is the first time that Karasuno witnessed Oikawa's serves and saw that they were not only very powerful, but Oikawa also had the ability to control where his serves could go. Oikawa is able to get two service aces in a row from targeting Tsukishima.

Even after Daichi takes on having a bigger receiving area, Oikawa still targets Tsukishima. The first-year was able to receive the serve this time but it would give Seijoh the chance to counter. In the end, Hinata is able to win the match for Karasuno by performing a wide broad attack that flies past a stunned Oikawa. As Karasuno began leaving the school, Oikawa confronted them outside and personally challenged them and Kageyama in particular. Oikawa is later talking with Iwaizumi about how different Kageyama seems since joining Karasuno but the ace player quickly becomes irritated when Oikawa admits that he wouldn't be able to match Kageyama's sets. Despite this, Oikawa feels confident that Seijoh will be able to beat Karasuno in a match and gleefully looks forward to that victory. Unfortunately, this brings on more of Iwaizumi's wrath.

On the first day of the Interhigh Tournament, Oikawa is with his team when they arrive at the Sendai City Gymnasium but he was pulled away from the group by several fangirls. As he is about to allow one to take a photo of him when he is suddenly hit with a volleyball. Initially angered, Oikawa quickly becomes fearful when he notices that it was Iwaizumi who had hit him. Not wanting to anger Iwaizumi further, Oikawa follows his friend into the gym[2].

As Seijoh is preparing to watch Karasuno's first match, Oikawa right away spots Hinata and Kageyama and teases them before Iwaizumi stops him. At this time, he notices that Karasuno has new players when he spots Nishinoya and Asahi. Oikawa doesn't show much interest in many of Karasuno's plays and only seems to become interested once Hinata and Kageyama start using their quick attack.

When watching Karasuno's match against Date Tech, Oikawa sees Hinata and Kageyama's quick set and expresses how annoying he finds geniuses. Shortly after, they manage another one, and Iwaizumi remarks that Kageyama's setting is the key component in their quick set, to which Oikawa brushes away in annoyance.

In the match against Oomisaki High, Oikawa is seen getting numerous service aces. It's in the second set after he has scored his fourth service ace in a row that Ukai points out that it's Oikawa's control of his serve that makes it a force to be reckoned with. He then refers to setters as conductors because they are the ones who control plays and Sugawara adds that Karasuno actually does not know much about Oikawa as a setter. Kageyama also reveals that Oikawa and Iwaizumi have been playing together since grade school which explains how the two are able to work so well together. Ukai surmises that Oikawa is the type of setter who knows his team so well that he is able to bring out one hundred percent of their abilities.

Oikawa shakes Daichi's hand before their match begins and Oikawa's fans cheer for him, which angers Tanaka and Nishinoya. As Aoba Johsai is warming up, Oikawa is seen interacting with his teammates. In the process of doing this, Oikawa asks Iwaizumi about whether he's trying too hard, but it wouldn't matter since all the girls would be looking at him. As the match is about to begin, Oikawa tells Kageyama that he's been looking forward to getting to beat him in public, and before he can answer, Hinata steps in.

Following this, Oikawa tells his teammates that he has faith in them. Upon hearing this, Takinoue notices a sudden change in attitude among Aoba Johsai's players. An observing Irihata internally explains that Oikawa always tells his teammates this before every game and as he has faith in them, they have complete faith in him as a setter. Directly in the first rally, Kunimi bumps the ball, and Oikawa leaps into the air and slams the ball right in the opposing court, pulling a dump. During the next rally, Oikawa seems to be about to do a setter dump but instead sets to Iwaizumi last minute. Right after, Kageyama attempts to do a dump himself, which he is successful at and tells Oikawa to watch out for an upcoming rally as he will be doing something like this again, which angers him.

Oikawa serves but points at Nishinoya before doing so. The libero does not think he can bump it as it goes too fast but ultimately is able to, ruining Oikawa's attempt to break Karasuno's spirit in pulling a serve that their libero couldn't even save. However, Ukai notices that it would unlikely for Oikawa to send any more serves Nishinoya's way. Kindaichi apologizes for falling for Kageyama's trick, but Oikawa tells him to brush it off as they also got many points from Date Tech with that technique. Additionally, he also tells him they'll figure it out in the end. However, he gets off-topic when he asks Kindaichi that seeing Hinata having stolen his spot as Kageyama's partner must have hurt him, which confuses Kindaichi, but Oikawa then lightly pushes Kindaichi to have faith and fly.

Later on, Hinata is used as a decoy, and Karasuno wins the rally. Despite this, Oikawa still smiles since it confirms what he noticed while watching Karasuno's match against Date Tech[3]. Oikawa is quick to tell Irihata this, which confuses the spectators because of the early timeout. However, he tells his teammates his speculations of the words 'bring' and 'give' to differentiate between their normal quick attack and their minus tempo one. When Iwaizumi tells Oikawa that a timeout at so early into the game would indicate to Karasuno that they've already figured out their strategy, Oikawa tells him that he wants this to happen for Kageyama to be on the edge. Not long after, Oikawa manages a setter dump from a distance. Right in the next rally, it would be Oikawa's turn to serve and he aims at Tanaka in hopes to kill Karasuno's spirits as he was the most energetic one. Oikawa continues to aim for Tanaka after this, which successfully pressures him for a few short moments before he would motivate himself and not fall for Oikawa's plan.

During the next timeout, the spectators notice Oikawa acting differently and not interacting with his teammates, and someone explains that he does this because he still wants to concentrate even though he isn't playing as not to mess up after the game resumes. Not long after, Iwaizumi tells Oikawa never to say that he could never beat Kageyama in terms of setting ever again. However, Oikawa tells him that he was only being honest, however, what he could do is put the ball up in the easiest way for each of the Aoba Johsai members. Following this, Kindaichi is able to go over Karasuno's blocks once more, and Oikawa scoffs to himself that this has always been Kindaichi's strong point.

Not long after, Oikawa admits to himself that Kageyama is a prodigy, but that he could also learn to use his other players and learn about them in order to score more points, and that's what he believes makes a good setter. Following this, Oikawa and Kageyama are stuck in a joust, but Oikawa easily overpowers his opponent. While observing the players, Irihata acknowledges that Kageyama has natural talent compared to Oikawa, but that Oikawa is clearly the better setter. When Sugawara is subbed in for Kageyama, Oikawa remembers back at what he observed from the warm-ups that Sugawara was just an average player, but he looked like a serious and careful person[4]. However, he also noticed that he was significantly shorter than Kageyama, which would let Aoba Johsai get through his block easier.

Two girls watching the match notice Oikawa frequently doing some hand signals, and question why he was doing so. Takinoue explains that he does so to indicate which kind of attack he wants them to do during the next rally. Following this, the score is 15-22, and it would leave Aoba Johsai a victory if they could get three more points, which they had high chances of getting because it would be Oikawa's turn to serve. Trying to stay motivated, Tanaka and Nishinoya are eager for him to serve, and Oikawa does so, but they can't do anything before the ball surpasses them and wins Aoba Johsai the rally. During his next serve, Oikawa hits Karasuno with a jump floater, which surprises them. This leaves the score to 15-24, and before his third serve, Oikawa tells his teammate that they will win that set to which Aoba Johsai answers with determination; however, Daichi is able to bump his serve.

During the second set, it's Oikawa's turn to serve, and the audience questions how Karasuno is going to receive it, but ultimately in the end Daichi manages it. Soon after, Oikawa acknowledges that Sugawara isn't a bad setter but that he just does everything by the book, and then tells his team to pull ahead for good. When Tsukishima is subbed in, Oikawa notices that he's probably the one Kageyama trusts the least. At Iwaizumi's spike against Karasuno, some spectators notice that Aoba Johsai's players are really good, but they keep getting forgotten behind Oikawa. Right after, it's Oikawa's turn to serve, and both Iwaizumi and Hanamaki in front of him tell him to smash it, to which he answers: "I know". When he serves, Oikawa aims to the back of the court, and Nishinoya is barely able to receive it. He then realizes that Sugawara probably taught him that, and Oikawa gets angry and is eager to play the next set. When Oikawa digs the ball and can't set, he calls for Watari to do so, and he scores. Not long after, Oikawa sets for Iwaizumi, and Takinoue is awed at how in sync the two are.

When Kageyama and Hinata pull their quick attack, Oikawa starts to get tensed and tries to do everything in his power to stop them. When Hinata is jumping, no one is targeting him, and Watari gets a clear view of where he needs to be to dig, which leaves confusion, letting Oikawa pull a dump. Not long after, Aoba Johsai is one point away from winning the match and attempts to pull a setter dump but Kageyama, right in front of him, manages a one-hand set and goes to Hinata, winning them the rally.

Oikawa serves, and there is tension since if he could win that point, Aoba Johsai would win. However, his serve goes out of bounds, just missing Nishinoya. Soon after, Iwaizumi knows that Oikawa is thinking of Ushijima while Aoba Johsai is just a few points away from winning but tells him that if he couldn't focus on his current opponents, he wouldn't be able to beat Shiratorizawa. Upon seeing Kunimi smile after winning a rally made Kageyama afraid because he didn't know how he could be able to beat Oikawa, someone who could make full use of all of his players[5].

After Kindaichi wins Aoba Johsai the match, Oikawa and his teammates all gather around each other, cheering at their victory. After their victory, Iwaizumi asks Oikawa why he didn't say anything to Kageyama after winning.

Oikawa goes into the match hopeful that Aoba Johsai will finally defeat Ushijima and Shiratorizawa. But despite all the work and practice that Aoba Johsai had done, they are ultimately defeated. Unlike other schools, Oikawa and the other third-years decide to stay on the team after the Interhigh in hopes of getting revenge on Shiratorizawa during the Spring Interhigh.

When leaving a Lil' Tykes Volleyball class with his nephew, Takeru, Oikawa runs into Kageyama. While the younger setter tried to obtain his help, Oikawa initially tried to ignore him until Kageyama put aside his pride and bowed to Oikawa. Oikawa took the chance to have his nephew take a picture of the encounter before agreeing to listen to Kageyama's situation of Hinata wanting to change the quick attack. Oikawa is supportive of Hinata wanting to change the attack and points out how the middle blocker is actually the one in control of the attack and not Kageyama. He continued to say that if Kageyama continued to be unwilling to change the attack, he would still be the same King of the Court he was during middle school.

Some time later, Oikawa welcomed Kentarō Kyōtani back onto the team after having personally asked him to return.

Before the qualifiers begin, Kageyama tells his team of Oikawa's practices with college students and how he was able to fit in with their team only after a few plays with them. Kageyama then explains that Oikawa could utilize any hitter he'd want in whatever way he needs. That evening, Oikawa seems to be catching a cold and gets offended when Iwaizumi threatens him if he were to actually get one. Not long after, Oikawa stops Yahaba from being aggressive towards Kyōtani and instead welcomes him back into the team. However, Kyōtani is kept in-check when Oikawa does not seem to get offended by this and instead intimidates the hitter by giving subtle hints of future practices. When Kyōtani backs off Oikawa, Kunimi compares this to Kyōtani having animal instincts.

As October comes around, the spring qualifier tournament begins. Despite being prepared when entering the man's bathroom, Hinata still manages to get intimidated when stumbling upon Oikawa and Iwaizumi there. Despite Iwaizumi being polite to Hinata, Oikawa becomes smug and wishes to crush him while outside the court. However, tension soon grows high as Ushijima arrives and unintentionally insults Oikawa and Iwaizumi, which provokes them.

When preparing for Aoba Johsai's own match to begin, Oikawa and Iwaizumi attend Karasuno's match against Wakutani Minami. When Iwaizumi wonders what happened to Daichi, Oikawa explains that there was a collision. As Daichi's conditions are being checked, Oikawa speculates that he might not return for the rest of the game and recalls stories he's heard when Iwaizumi is afraid Daichi might have gotten a concussion.

When seeing Tanaka blaming himself for Daichi's injury, Oikawa wonders how he would hold up since, unlike in their match against Aoba Johsai during Interhigh, Tanaka had affected another player's state, not his. Upon Iwaizumi suggesting that Karasuno might have both of their setters on the court, Oikawa doubts it and wonders if they even have a wing spiker who could hold Daichi's weight. Seeing Ennoshita get subbed in for Daichi, Oikawa asks Iwaizumi about his performance during the practice game. When Iwaizumi answers that he was simply getting the job done, Oikawa speculates that Karasuno most likely doesn't have anyone to hold the fort.

As Date Tech's game against Aoba Johsai is about to begin, Hanamaki wonders how Karasuno is doing without their captain. At this, Oikawa speculates that without their captain and main defensive player, this would make Karasuno realize that Daichi was, in fact, an irreplaceable part of their team.

As Oikawa shakes Futakuchi's hand, he attempts to be friendly with the opposing captain and assures him that he would still have the following year to win the tournament once they lose his one. At this, Futakuchi gets on the defensive and tells Oikawa to disregard age and ranks as Date Tech's only goal is to win.

During the second set, Watari sets to Oikawa. Because of Date Tech's excellent blocking, he has trouble finding cracks in the enemy block to score. He finds a spot to hit, but seeing Koganegawa barge in and block him, surprises him and expresses how frustrating it was to have to go against such a difficult team to defeat and seems the most concerned of Koganegawa's presence during the game as the first-year setter adds height and strength to Date Tech's famous iron wall despite his inexperience. Following this, Iwaizumi and Hanamaki both insult him and Oikawa reminds them that he could hear them. Not long after, Oikawa serves and ultimately scores a service ace. At this, Karasuno, who is watching the match, finally notices that Aoba Johsai has the upper hand in the match. However, Oikawa shows further concern when Koganegawa rotates back into the front row. Trying to conquer the block, Oikawa sets to Iwaizumi, but he is unable to score. Iwaizumi notices that he deliberately set away from the net for him to get past the blockers and tells Oikawa to let him fight his own battles.

Oikawa is quick to agree to Iwaizumi's statement and returns to setting like normal. This would allow Iwaizumi to take the Iron Wall head on and win the match when he took advantage of Koganegawa's inexperience by spiking through his arms as they were too wide to stop the ball.

Before the match beings, Oikawa notices a different atmosphere around Karasuno, and right after he finishes his sentence, a ball Kageyama had left rolls around and they both fight to grab it. As this happens, Oikawa reminds Kageyama of their previous loss and declares he will defeat them once more. He then releases the ball and Kageyama falls to the ground. When shaking hands with Daichi, he remarks a new sense of dignity that the opposing captain has picked up. Right after, they toss a coin to find out who will serve.

After this, he admits to his team that Karasuno would be a troubling team to go up against and before he is about to tell his team that he has faith in them, the third years cut in by stating their own faith in their captain but warn him that he will owe them ramen after the match if he does not land his first serve. As he serves, Daichi is frustrated at how Oikawa's serve is still as strong as the previous games, but he is still able to receive it.

Near the end of the set, Oikawa prepares for a hard serve, but Iwaizumi predicts otherwise and it goes out of bounds. However, Daichi notices that he is deliberately going for greater power even though he knows he's risking more outs. Although he is the one that invited Kyōtani into the team, he is still surprised when he suddenly dives in to interrupt Oikawa's set to Kindaichi. After this, Oikawa is offended at how Kyōtani is only willing to listen to Iwaizumi. In the next rally, Oikawa fails his serve again, but Daichi notices that he's only getting adjusted to using so much strength in his serves. However, he would then set to Kyōtani, using a minus tempo attack but also conquer the blockers with an extreme angle. When Oikawa notices Kindaichi worrying in the next rally, he tells him not to be worried when being paired with Kyōtani because he isn't always a 'mad dog'.

After Kyōtani manages to score three points in a row, Oikawa fools the blockers by setting to Kindaichi rather than Kyōtani. Oikawa notices that Kyōtani is frustrated because he has just been used as a decoy, but Oikawa plans to himself to "sharpen Kyōtani's fangs". Not long after, Oikawa makes full use of Kyōtani when setting to him and being able to get past enemy blocks. In the next rally, Oikawa requests Watari to purposely use a botched pass and a decoy to lure Karasuno's blockers to the left to open up the right side for an attack from Kyōtani. Watari and Kyōtani successfully pull it off, and as this happens, Oikawa thinks to himself that Kyōtani is no doubt a double-edged sword, but that is exactly the reason why he's trying to use him as much as he can.

Although Hinata and Kageyama attempt to surprise Aoba Johsai with a back-row set, Oikawa still blocks them because he noticed that Hinata hasn't been attacking much lately so Kageyama figured that now would be the perfect time to do a quick set, Oikawa had figured that as well. Shortly after, Oikawa finally manages to score with his serve, and he scores an ace. This brings Daichi back to reality and realizes that just for this tournament, both teams have trained extremely hard, but he admits that it is also absolutely terrifying to him. During the second rally, Oikawa would set more often to Kyōtani, and Karasuno believes that this is to throw them off with another player later. This is referenced back to when Matsukawa seems to creep behind Kyōtani as to use him as a decoy but ultimately Oikawa sets to Kyōtani.

After Yamaguchi scores a streak of aces, Oikawa tells his team not to be panicked, but this only results in him getting upset because they didn't need his advice. Soon after, Oikawa is up to serve. He manages to get past Nishinoya, which motivates his entire team. At his second serve, Oikawa aims at Karasuno's other receiver, Daichi, and he successfully receives it. After the second set ends, Hinata praises Yamaguchi for his serves, but Yamaguchi answers that Oikawa is still better because he was able to go beyond his previous skills, which he admits is terrifying to him. Noticing that Kyōtani is agitated because of Tanaka, Oikawa decides to set to him in order for him to gain a point that he lost back, but ultimately, it goes out-of-bounds. Once Kyōtani is subbed back in after being subbed out to put himself together, Oikawa sets to him once more. After Kyōtani is able to get past Karasuno's defenses, Oikawa praises him for that, and Kyōtani quietly thanks him.

Shortly after, after Kindaichi scores thanks to Oikawa, Kageyama notices that he isn't using Kindaichi the same way as he did during the Interhigh tournament. When the match points reach the 20s, Oikawa scores a service ace and completely changes the game's atmosphere. As Aoba Johsai is one point away from winning. Oikawa serves, but Daichi is able to receive it. After Kageyama scores a dump, Aoba Johsai requests a time-out, and Yahaba expresses how he wishes Kageyama could've shared his skills as a setter with him. Upon hearing this, Oikawa remembers back at how even though the efforts for his work may not appear right away, his talent could always show up another time if he still keeps practicing, but it never will if he doesn't think he has it, and Oikawa tells this to Yahaba and Watari next to him, which leads the both of them to find that their captain has changed.

During the final rally, Hanamaki has a hard time bumping Asahi's spike but manages to do so. Oikawa, desperate to win, goes as far as to leap out of the court to set to Iwaizumi, who is also on edge to score. As this happens, Oikawa realizes that talent is something that blooms, not something that someone is born with. When Iwaizumi, Kunimi, and Kyōtani's triple block fails, Oikawa attempts to dig Hinata's spike but fails, resulting in Aoba Johsai's loss. Oikawa then confronts Kageyama and quietly tells him not to take this victory to his head. After this, he sees Iwaizumi break into tears and blaming himself for not being able to hit Oikawa's perfect toss but after a slap in the back from each of the third-years, he comes back to his senses.

Oikawa then encounters Ushijima. Ushijima tells him that Oikawa lost because he chose the wrong path and that he should've gone to Shiratorizawa instead of Aoba Johsai. Oikawa then laughs when Ushijima boldly claims that whatever team he's on would make it the best. Additionally, he tells his rival that he still wasn't over yet and that he will never regret choosing Aoba Johsai over Shiratorizawa but that Karasuno would still beat them.

That evening, at a ramen shop, Oikawa tells his team that they had the potential to get to nationals that year but gets frustrated when Hanamaki still thinks that they would've gotten crushed in the first round. Nevertheless, that evening, Iwaizumi has a competition with Oikawa to determine who had the more right to be upset over their loss. Shortly after, the club's third-years all play together. As they are about to wrap things up, Hanamaki senses that Oikawa is about to end off with a happy message to conclude their volleyball career and they all break into tears.

Iwaizumi and Oikawa would soon walk home together. Iwaizumi tells Oikawa that he doubts Oikawa would ever be happy because he can't see him be satisfied, even with perfection. However, he and Iwaizumi both fist bump and thank each other for being such great partners.

Oikawa and Iwaizumi attend the match between Karasuno and Shiratorizawa though Iwaizumi states that Oikawa had claimed he would not attend the match because he would be angry no matter which team won. They appear after Tsukishima's return to the court during the final set (They appear in the fourth set in the anime). When the match is over and Karasuno has won, the two realize that Karasuno's victory is partly due to Tsukishima's plan of trying to get Ushijima into the habit of hitting straight shots out of muscle memory. Oikawa then ushers himself and Iwaizumi out of the gym before the award ceremony.

Oikawa makes a brief appearance when he is seen watching Karasuno's game against Inarizaki[6]. He is seen once more when he is watching Karasuno play against Kamomedai High after Hinata is removed from the game and Karasuno eventually lost[7].

After high school, Oikawa became a professional volleyball player for the Club Atlético San Juan, a professional team in the Argentine Volleyball Federation where he plays as the setter[1]. On a trip to Rio de Janeiro, Oikawa runs into Hinata one night at the beach when the younger player was playing beach volleyball.

After Hinata's game ends, the two head to dinner together where Hinata questions Oikawa why he went to Argentina. Oikawa reveals that he has loved volleyball since he was a child but became fully enamored with the sport when he and Iwaizumi attended a match between Argentina and Japan. The ace player of the Argentina team had been having trouble in the game until the coach switched the setters. The new setter, Jose Blanco, was able to bring the ace back on track through easy to hit sets. It was through his actions and a brief conversation with Blanco that Oikawa decided to become a setter. After having learned that Blanco was acquainted with Coach Irihata, Oikawa would pretend he was unsure of whether or not he wanted to continue with volleyball just to be able to speak with him. Blanco quickly figured out that Oikawa was just pretending to be unsure of where he stood with volleyball but would still give advice on things that Oikawa was truly troubled with, such as comparing his own skills and talent to those of others who appeared to be naturally gifted.

Hinata proposes they play a game of beach volleyball together. Oikawa confidently accepts but finds himself struggling with the sand and wind, much to Hinata's amusement. Despite this, Oikawa listens as Hinata explains how he had been rather down earlier but getting to spend time with his former rival has put him in a much better mood. The two would soon be challenged to a game by the 'Buy me a Beer' brothers. Oikawa would attempt to demonstrate his jump serve but failed horribly due to the wind affecting the ball. He and Hinata are quickly defeated and buy the Brazilian men their beers. However, Oikawa quickly adapts for their following game a week later against Gabriel and Gino. He would even offer Hinata advice on how to observe their opponents and take them by surprise after predicting the next steps. Thanks to playing with Hinata, Oikawa rediscovers the joy of playing volleyball again[8]. The two were able to win their match and are treated to dinner by Gabriel and Gino.

Before leaving Brazil, Oikawa begins addressing Hinata by his first name and promises that he would defeat Hinata if they ever face-off in a match.

By 2021, Oikawa has naturalized as an Argentinean citizen[9]. He would play on the Argentinean National Team, coached by Jose Blanco, at the Olympics where he would face many of his rivals on the Japan team. He and Hinata are seen sharing an embrace before the match. Oikawa is first to serve in the game and his serve is shown to be just as powerful as ever, although Sakusa was seen able to dig the ball.

He is most feared for his powerful and accurate jump serve, which he has honed and perfected from a young age. He can maintain a calm and cool composure during any match, no matter how tense it is. Despite not being considered a "genius" by mainly his coach and himself, Oikawa is a stunning player and one of the best all-around players in the prefecture.

Oikawa's talent lies in his natural athletic ability, his skill to make full use of his teammates, finding weaknesses in the opposing teams, sharp aims, and powerful serves. Within a short span of time on the court, he was able to point out that Tsukishima and Hinata were weak at receiving, and break Kageyama and Hinata's god-like quick. This, however, is not without years of dedication and practices. His talent is widely recognized and is even acknowledged by Ushijima from Shiratorizawa Academy, who states that Oikawa's talent lies in his ability to draw the full potential out of any team.

Jumping Reach: 335 cm

Family name: Nakashima 中島 /na'kashima/

中 (/naka/) - "center", "inside"; used in many Japanese family names, notably Tanaka and Nakata/Nakada (which use the same kanji, just in different order: 田中 and 中田)

島 (/shima/) - "island"; also found in many Japanese family names, notable examples from Haikyuu are Tsukishima and Ushijima (where the /shima/ reading changes to /jima/ due to rendaku)

Translation: "island in a pond/river/lake"

As with all Wakutani Minami characters, Nakashima is a reference to locations in Miyagi prefecture. However, it's pretty hard to determine which location exactly he is a reference to due to the commonness of the name.

中島 is the most common family name so far, with nearly 100 000 households with the name (source). However, there are several possible readings, though Nakashima is the most common.

Given name: Takeru 猛 /ta'keru/

猛 (/takeru/) - "to be fierce"; rarely used in the verb form, most often found in words such as "fierce" (猛烈 /mouretsu/) and "heavy blow" (猛打 /mouda/), where it is read with its on-yomi (adopted Chinese reading); the reading /takeru/ is also probably a reference to the verb "to excel" (長ける)

Translation: "to be fierce", "to excel"

Kanji meaning and associations with the name (source):

たけし。たけだけしい。いさましい。あらあらしい。きびしい。はげしい。いかる。(Takeshi. Takedakeshii. Isamashii. Araarashii. Kibishii. Hageshii. Ikaru.)Brave, valiant, courageous, rough/wild, strict, fierce. To get angry.

The name fits Nakashima quite well, with fierceness and excellence being the dominant ideas. Considering that Nakashima is one of the highest ranked players, I think the excellence part is especially important.

Takeru is an exclusively male name and 猛 seems to only be used in male names. It is a decently lucky name and even becomes luckier in combination with Nakashima as a family name (source).

Bonus stuff: Yesterday I wrote about themes in family names. Nakashima and his siblings are an excellent example of this, with all children having one kanji and pretty straightforward readings. Boys' names are in verb forms, while the only girl is a noun. A quick rundown: Isamu (勇 "to be lively", appears in Kindaichi's name), Minoru (実 "to bear fruit"), Makoto (真 "truth").

Family name: Oikawa 及川 /'oikawa/

及 (/oi/) - "reach", "extend"; found in the verb 及ぶ /oyobu/

川 (/kawa/) - "river"; used in many Japanese family names

Translation: "extending river"

Given name: Takeru 猛 /ta'keru/

See above.

Since we didn't get much characterization for Oikawa's nephew, it's hard to tell how this name applies to him. However, we see him being rather strict with his uncle, so that might be somewhat of a reference.

As mentioned, Takeru is a decently lucky name based on the number of strokes and gets a bit less lucky with Oikawa as a family name (source).

Bonus stuff: I'd say that the Oikawas also exhibit thematic naming, with both of them having a single kanji name in a verb form. I wish we'd gotten the sister's name as well to confirm it (as a side note, I once read a fic where the author picked up on the pattern and gave the sister an excellent name, sadly I didn't save it).

Japanese names overview

That's it for today! Again a fun one! I've decided to do Mon-Tue-Thu posts, though that may change.
