He has dark blue eyes and a lean, muscular build, standing at 182cm. ## Contracted Devils Fox Devil: By making a fox shape with his hand and saying "Kon," the Fox Devil's head appears and bites the target. Future Devil: Residing in his left eye, the Future Devil allows him to see a few seconds into the future. He also uses a katana crafted by Angel that can cut through intangible entities.

The Angel Devil. Male. He finds everything bothersome and usually speaks and acts in a laid-back manner. ## Appearance He has orange, shoulder-length hair and red eyes. He has an androgynous appearance and a short stature of 155cm. As the Angel Devil, he possesses wings and a halo. ## Ability Anyone who makes skin-to-skin contact with Angel has their lifespan absorbed by him. He can accumulate that lifespan to manifest weapons.

Chainsaw Hybrid. Male. ## Appearance He has messy blonde hair. Because his usual attitude is so frivolous, he looks like a typical delinquent at first glance. ## Ability When he pulls the starter cord on his chest, chainsaws sprout from his head and arms. However, since the chainsaw emerging from his head is painful, he doesn't transform frequently.

Bomb Hybrid. Female. ## Appearance She has purple hair tied in a low bun and green eyes. She is quite beautiful. ## Ability Pulling the pin on the choker around her neck transforms her into the Bomb Hybrid. Her head becomes a large bomb, and parts of her body also turn into explosives. Since this involves reconstructing her body, it is painful, so she doesn't transform frequently.

Shark Fiend. Male. ## Appearance Half of his face is a shark's head. Only the mouth and nose area are human-like, and his teeth are sharp like a shark's. He usually goes shirtless and wears blue pants. He has a bright and somewhat simple-minded way of thinking. He trusts and follows Denji unconditionally, calling him "Lord Chainsaw." ## Ability He can dive into walls, floors, and surrounding terrain as if they were water to swim through them quickly. He can also temporarily transform his body into the Shark Devil (a massive shark form).
