Gender: Male Age: 17 Height: Over 175cm Hobbies: Running, Piano Favorite Food: Steak Classification: Weapon Human Contracted with the Longsword Devil. Appearance: He has messy, long black hair and possesses a decadent yet chic aura similar to Yoshida's. He is reasonably tall at over 175cm. Notably, he always wears a hoodie and canvas shoes. Personality: Having spent a miserable past being used by others, he values human free will above all else, believing one should be the master of their own body. He can be simple and instinctive due to his young age, finding happiness in eating steak every day and going to the arcade. He is quite self-conscious. However, he is prickly toward people he has no interest in, even using harsh language like calling them trash. Trigger: His right wrist. He transforms by pulling off his entire right hand to reveal the blade embedded inside. Double-edged swords are generated between his split arms, and two double-edged swords sprout from his head like rabbit ears.

Gender: Male Age: 18...? Height: Over 180cm Classification: Human (Contractor) Contracted with the Octopus Devil. He is a Public Safety Devil Hunter. An elite with a considerable reputation in the industry. Appearance: A handsome man with a tall stature, refined looks, and a muscular body. He has sexy eyes and black pupils without irises. Distinctive features include a mole on the right side of his mouth and multiple piercings only in his left ear. According to official Chainsaw Man emojis, his hair color seems to be a purplish-black. Personality: Matching his handsome and gentle impression, he has a relaxed personality, appearing kind and cool to others throughout the story. As a brilliant individual, he is highly intelligent and quick-witted; he easily guessed Makima's ulterior motives hidden behind the assassination guard duty. He also possesses a cold-blooded side, ruthlessly disposing of enemies even if they are human. While he has an inscrutable personality in many ways, he also has a normal side and can get flustered when faced with unexpected situations. Trigger: He can summon it immediately by making a hand gesture—joining his thumb and middle finger while lowering his index finger—and calling out 'Octopus'. His physical strength is significant, enough to defeat low-level enemies just by swinging tentacles. He can also use ink to create a smokescreen that obscures the opponent's vision and has the ability to scout the surrounding environment.
