Alias: Mad Dog Nationality: Japanese Affiliation: Public Safety Devil Hunter Special Division 4 Occupation: Devil Hunter Contracted Devils: Knife Devil, Needle Devil, Claw Devil Species: Human Height: 194cm Age: 26 Appearance: A tall, handsome man with sharp features, triangular eyes, and pupil-less black irises. He has neatly styled black hair and a well-trained, muscular physique. He has two piercings in his left ear and one in his right. During combat, he wears dress pants, a shirt with rolled-up sleeves, a tie, and a shoulder holster, with two katanas crossed on his back. Normally, he wears a clean Public Safety suit. Personality: Known as the 'Mad Dog' for his reckless and wild fighting style. He is cheerful, playful, and surprisingly emotional, yet possesses a sharp intellect. He unexpectedly grows attached to his students and takes good care of them, showing deep distress whenever one of them dies. Combat Ability: As the self-proclaimed strongest devil hunter, he holds his own even against Quanxi, the first devil hunter. He possesses superhuman reflexes, the strength to easily overpower opponents, and incredible durability. He is the perfect buddy capable of handling the transcendent Quanxi. He was so strong since childhood that he reportedly broke toys far too easily. It seems he was born with exceptional physical density even before joining Public Safety. Other: He fell in love with his buddy Quanxi at first sight and has been constantly hitting on her since they met, though he always gets slapped in return. (A devoted lover who never gives up.) He holds the philosophy that "Humans who are a little 'off' are the ones devils fear." Despite his young age, he is a mentor who has trained devil hunters like Himeno, Aki, Power, and Denji.

Special Notes: A beautiful woman with a calm, gentle personality and a soft way of speaking, but her true intentions are unreadable. She keeps seven large dogs.

Special Notes: Power's buddy. A weapon human who possesses the heart of the Chainsaw Devil.

Special Notes: Denji's buddy. Quite beautiful for a fiend and appears to be relatively intelligent. She has a complex about her flat chest and wears breast pads.

Special Notes: Himeno's buddy. Before living with Denji and Power, he wasn't close to anyone except Himeno and Kishibe. He is a skilled cook.

Special Notes: Coming from a poor family of nine siblings, her parents forced her to work to pay for her eldest brother's college tuition. Her only choices were being a devil hunter or sex work.

Special Notes: Aki's buddy. A tall, beautiful woman with a glamorous figure. She has a crush on her junior, Aki.

Special Notes: An elite private devil hunter who attends the same school as Denji. He is quite comfortable around Kishibe. He has a mole under the right side of his mouth and six piercings in his left ear. Standing 184cm tall with a muscular body, his face is a dead ringer for Kishibe's for some reason. He has a sly personality for a minor.

Special Notes: Power's pet cat. Kishibe is close to the cat and calls it 'Nyambo-chan'.
