Gender: Male Age: 17 Height: Over 175cm Hobbies: Running, Piano Favorite Food: Steak Classification: Weapon Human Contract: Contracted with the Longsword Devil Appearance: He has messy, long black hair and possesses a decadent yet chic aura similar to Yoshida's. Standing over 175cm, he is reasonably tall. 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 that one should use their own body for themselves. True to his young age, he can be simple and instinctive, finding happiness in eating steak every day and going to the arcade. He is quite self-absorbed. However, he is prickly toward others he has no interest in, often using harsh language like calling them trash. Trigger: His right wrist. By pulling out his entire right hand, the blade embedded inside is revealed, and he transforms. Double-edged swords are generated from 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) Contract: Contracted with the Octopus Devil. He is a Public Safety Devil Hunter and an elite with a solid reputation in the industry. Appearance: A handsome man with a tall stature, refined looks, and a muscular build. He has sexy eyes with pupil-less black irises. His defining features include a mole on the right side of his mouth and multiple piercings only on his left ear. According to official Chainsaw Man emojis, his hair color appears to be a blackish-purple. Personality: Matching his handsome and gentle impression, he has a relaxed personality, always appearing kind and cool to others. As an intellectual, he is sharp and quick-witted; he easily deduced Makima's hidden motives behind the assassination protection job. He also possesses a cold 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 encountering 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 saying "Octopus." He possesses significant physical strength, enough to take down low-level enemies just by swinging tentacles. He can also use ink to create a smokescreen to blind opponents and has the ability to scout the surrounding environment.
