why aki become gun devil?

When summoned by the President of the United States, the Gun Demon's body resembles a monstrous humanoid figure with several building-sized rifles in place of weapons, a skeletal body filled with screaming disembodied heads, and a gun barrel of large size emerging from its skull-like face.

The main parts of the arms appear to be M4 carbines, with other assault rifles on their arms. The AK-47, the M16A1, and the Mk18 assault rifle are included. The arms are holding the same rifles. The slide and barrel of a large M1911 appears to be the head of the Gun Demon.

His back has any firearm attached to it.

The Gun Demon's personality is not known.

Weapons were used as a countermeasure against demons for 13 years before the present. The use of weapons increased during crimes and civil unrest. The media coverage of gun crime in all countries has increased the fear of guns in the world.

The Gun Demon struck Japan for 26 seconds, killing 57,912 people, on November 18th, the day after a major terrorist gun attack in the United States. Aki Hayakawa witnessed the Gun Demon destroy his home and kill his family when he passed by. It successively affected various countries around the world, ultimately causing a toll of 1.2 million lives in just five minutes. Aldo, Joey, and his brother survived the Gun Demon attack but lost their home along with their father, mother, and grandmother.

They would believe that they are immortal because of this event.

The impact of the Gun Demon on human society led to an increase in fear in all demons.

The Gun Demon was shot down and found unconscious by the Soviet Union. His body is held by some countries and demons.

Makima wants Denji to defeat the Gun Demon, who is currently unknown. She offers to grant him whatever wish she has if she can kill him. Makima explains the history of the Gun Demon to Denji and tells him that they are currently trying to track him down using pieces of the Gun Demon's flesh. Meanwhile, Aki and Himeno defeat a demon and recover a piece of the Gun Demon's meat. The attraction of the Gun Demon's flesh leads them to the Hotel Morino, where a six-man team is sent to investigate.

Aki comments that demons with parts of the Gun Demon are becoming more common.

Denji, Aki, Himeno, and Power were confronted by a man who told them a story about his grandfather. Denji, Aki, and Himeno were wounded when the Gun Demon opened fire after he finished.

After learning from Madoka that most of the humans in Special Divisions 1, 2, 3, and 4 have been killed in coordinated weapon attacks, Makima states that it is likely the Gun Demon. However, Makima later claims that these weapons are manufactured by humans in secret despite international law.

The Bomb Demon is the ally of the Gun Demon, according to Beam Aki. When asked how he knows him, Beam said he would be killed if he revealed the information and promised Makima that he would keep it a secret.

Makima says that the Gun Demon is already defeated and its pieces are held by different countries.

The United States, the Soviet Union, China, and four other countries have possessed a large portion of his body.

The President of the United States has a contract with the Gun Demon to kill Makima in exchange for one year of life for every person in the United States. The Gun Demon hit the city of Nikaho in Akita Prefecture, Japan, in 1997. Immediately after he appears, he shoots bullets. The Gun Demon is killing people and destroying cities.

Makima sees it at a distance of 500 kilometers. The gun devil stops shooting. Makima activated his ability before a bullet hit him. He killed Aki and Makima. Makima's 29th kill was recorded.

Makima has the ability to use Aki Hayakawa, Michiko Tendo, Yutaro Kurose, and Akane Sawatari's contracts and abilities.

Makima failed to defeat the Gun Demon. The Gun Demon Man was created from the remains of Aki Hayakawa. The demon man went as far as knocking on the door of Aki's residence.

Denji was shot in the stomach by the Gun Demon Man after being told to do so. Denji and Power are sent flying through the air in the direction of Aki's residence after the attack. Denji and the Demon Gun Men engaged in combat, which destroyed a large part of the surrounding residential area.

Denji defeated and killed the Gun Demon Man after getting blood and pleas from the area's residents.
