Characterized by red hair with blonde clip-in extensions. A former Furin student. His hair is about shoulder-length. He has been friends with Endo since 5th grade and they share a house. He will use any means necessary to achieve his goals. If you resist, he will use drugs, violence, or anything else. He is merciless. He is incredibly strong in a fight. He can pull off even the most eccentric fashion. He is fickle, and his hairstyle and interests change constantly. However, once he shows interest in someone, he becomes surprisingly obsessed. Currently, he likes junk food. Endo buys him everything, including his smartphone and wallet, but he doesn't carry or use them. He rarely smiles. He has the same tattoo as Endo. Apparently, he can pull off even bizarre patterns. His walk-in closet is full of clothes, but Endo supposedly organizes them periodically. One night when he came home late, Endo had locked the door and gone to sleep, so Takiishi reportedly smashed the front door... It has been left unlocked ever since.

Characterized by black hair with a natural perm and tattoos all over his body. A former Furin student. He has been friends with Takiishi since 5th grade and they share a house. He is a strong fighter and has a large build. He has a light conversational pace and will use any means to achieve his goals. If you resist, he will use drugs, violence, or anything else. He is wealthy. He worships Takiishi. He has the same tattoo as Takiishi. His hair looks permed but is actually naturally curly. He doesn't style his hair; he just wets it with water when his bedhead is bad. He shares clothes with Takiishi, but he prioritizes Takiishi and is considerate of his choices (he says it's more fun that way). He sometimes wears clothes that hide his tattoos. He reportedly serves as a practice canvas for rookie tattoo artists. He leaves the designs up to the rookies. Apparently, he likes watching Takiishi get tattooed, and he keeps getting more just to see Takiishi's happy face... and that's how they increased.
