The Gun Devil (銃の悪魔, Jū no akuma) is a very powerful devil who embodies the fear of guns.


When summoned by the President of the United States, the Gun Devil's body resembles a monstrous humanoid figure with multiple building-sized rifles for arms, a roughly skeletal body crammed full of disembodied screaming heads, and an oversized gun barrel emerging from its skull-like face.[1]

The main parts of both its arms appear to be M4 Carbines, with other well-known assault rifles in its arms well. These include: the AK-47, the M16A1, and the Mk18 assault rifle. Both arms appear to wield the same rifles. The Gun Devil's head appears to be the slide and barrel of a large M1911 missing the hammer. Any firearms attached to its back are unidentifiable.


The Gun Devil's personality is currently unknown.



Thirteen years before the present day, the whole world tried to cash in on guns as a countermeasure against devils. This led to an increase in gun use during crimes and civil revolts. Due to heavy media coverage of gun crimes in every country, worldwide fear of guns has increased drastically.[2]

The Gun Devil's Destruction

On November 18 a large terrorist attack involving guns occurred in America, causing that to be the day that the Gun Devil first appeared.[3] The Gun Devil hit Japan for 26 seconds, killing 57,912 people. Aki Hayakawa witnessed the Gun Devil destroying his house and killing his family as it passed by.[4] It hit several countries around the world in succession eventually leading a death toll of 1.2 million lives in only five minutes.[3] Aldo, Joey and their brother survived the Gun Devil's attack but lost their home along with their father, mother and grandmother. This would one of the events in their lifes that would lead them to believe that they're immortal.[5]

After that the Gun Devil disappeared but its impact on human society led to an overall increase in fear in all devils.[6] An international law has been prepared to strictly control the manufacturing of arms in every country to lower the fear of guns.[7]

At some point of time, the Gun Devil has been taken down by someone unknown and he was found by the Soviet Union while he was in an unconscious state. His body is seperated into several pieces and held by countries and devils.

Bat Devil arc

Makima asks Denji for a favor; she wants him to defeat the Gun Devil whose location is currently unknown. She offers to grant any one wish he has if he can kill it.[8]

Makima explains the history of the Gun Devil to Denji and explains that they're currently trying to track it using pieces of the Gun Devil's flesh.[9] Meanwhile Aki and Himeno take down a devil and recover a chunk of the Gun Devil's flesh from it. The pull of the Gun Devil's flesh leads them to Morino Hotel where they dispatch a six-man team to investigate.[10]

Eternity Devil arc

A piece of the Gun Devil's body is recovered by Aki from the Eternity Devil's corpse.[11] Later at a party Aki comments that devils with Gun Devil pieces are becoming more common.[12]

Katana Man arc

The Katana Man confronts Denji, Aki, Himeno and Power in a restaurant and relates a story to them about his grandfather. As he finishes up, he tells Denji that the Gun Devil wants his heart and opens fire, wounding Denji, Aki and Himeno.[13] Simultaneously most of the members of the Special Divisions elsewhere are assassinated.[14]

After learning from Madoka that most of the humans in Special Divisions 1, 2, 3 and 4 have been killed in coordinated gun attacks, Makima states that it is likely the Gun Devil is involved.[15] However, Makima later claims that these guns are manufactured by humans secretly despite the international law.[7]

Bomb Girl arc

Beam tells Aki that the Bomb Devil is the ally of the Gun Devil. When pressed on how he knows this Beam claims that if he reveals this information that he will be killed and that he promised Makima to keep it secret.[16]

Gun Devil arc

Makima reveals that the Gun Devil is already defeated and its separated pieces are held by various countries. Currently, twenty percent of his body is possessed by America, twenty-eight by the Soviet Union, eleven by China, four by other countries and the remaining thirty-seven is held by devils around the world as flesh pieces.

The President of the United States contracts with the Gun Devil to kill Makima in exchange for one year lifespan of every citizen of the United States. On September 12, 1997 the Gun Devil hits the city of Nikaho in Akita Prefecture, Japan from off the coast for 12 seconds. Immediately upon his appearance, he activates his ability to fire bullets. The Gun Devil advances toward Makima while killing the people and destroying the cities he passes. He is sighted by Makima at a distance of 500 kilometers. The Gun Devil stops and he begins gunfire towards Makima. Makima activates her ability before she is shot by one of the bullets. He kills Aki and Makima. It is recorded that it is Makima's 29th death. To counter it, Makima activates her ability to use the contracts of Aki Hayakawa, Tendo, Yutaro Kurose and Akane Sawatari and the abilities of Spider Devil and Angel Devil.

However, Makima "failed" to defeat the Gun Devil. His remnants possessed the corpse of Aki Hayakawa and they become a Gun Fiend. Swiftly, the fiend moves towards Aki's residence, and arrives with a knock at the door. Denji, after being told to by Makima, opens it, and after a few short seconds, is shot in the stomach by the Gun Fiend. This attack destroys a large amount of Aki's residence, and sends Denji and Power flying through the air in the direction of the attack. The Gun Fiends then engages in combat with Denji, destroying large parts of the surrounding residential area. Denji, after receiving blood and pleads from the residents of the area, then overpowers the Gun Fiend, defeating and killing it.


Physical Abilities

Immense Speed: The Gun Devil is incredibly fast, able to kill 1.2 million people in various countries across the world in five minutes.[17] Its speed is so great that pieces of its flesh burned off of its body as it moved.[18]

Supernatural Abilities

Bullet Projection: The Gun Devil is able to fire bullets from the several guns which are parts of its body with great precision and speed. He is able to fire a bullet through the head of every adult male within approximately 1000 meters of himself, fire a bullet through the head of every child up to 12 years old within approximately 1500 meters[19] and fire a bullet through the heart of every living thing born in January, February, March, May, June, August, September, November or December in approximately 1000 meters of himself.

Bullet Flesh: The Gun Devil can discard its own flesh which resembles bullets due to its own speed and power. When devils of any type consume pieces of the Gun Devil's flesh, their power is greatly enhanced. These bullet parts attract with each other and fuse together when touching and will attempt to rejoin the Gun Devil's main body to regenerate.[18] As stated by Makima, his body is currently separated into several pieces and remains in a unconscious state. Twenty percent of his body is possessed by America, twenty-eight by the Soviet Union, eleven by China, four by other countries and the remaining thirty-seven is held by devils around the world as flesh pieces.

Contract Creation: As a devil, the Gun Devil can bestow contracts upon humans for a price. The contracts with it seen so far are:

  • A contract with the President of the United States in exchange for one year lifespan of every citizen of the United States to kill Makima.[20] It is unknown that this contract has been made by complete body of Gun Devil or twenty percent of it.

Blood Consumption: As a devil, the Gun Devil should be able to restore its health by consuming blood.[21]

Revival: As a devil, the Gun Devil should revive in Hell after being killed effectively making it immortal.[22]
