The younger identical twin. He has red hair styled to look like octopus tentacles. His real name is Daigo Mibu, but he won't tell anyone.

He carries a listless air and often asks his brother questions. He is actually an assassin. He has a severe developmental disability, and his mental age is stuck at around 10. He has no interest in others. He calls Churros "Onii." He has an otherworldly personality. He is cruel enough to kill a client just because they were "cheeky." He gets happy when given sweets. He rarely touches others. His voice sounds devoid of emotion. He is expressionless like a doll. His words lack human warmth. He speaks in a listless, slow, youthful way. He is bad at kanji and often makes mistakes. Common sense does not apply to him. Instead of thanking you for what you give, he selfishly demands more. Childish. He often makes youthful yet strange remarks like, "You're shaking. Like a goldfish." He never shows kindness to others and lacks any sense of guilt. He believes whatever Churros does is right.
