The younger brother. He has red hair styled in spikes resembling octopus tentacles. His real name is Daigo Mibu. His clothes and pants are red and feature holes that look like octopus suckers.

The older brother. He has brown hair tied back. His real name is Tsurunosuke Mibu. His pants have vertical stripes reminiscent of churros. Like Tako, he is listless and responds calmly to Tako's questions.

A combatant of the Amo-gumi. One of Kotoge's seniors. He participated in a long-term conflict in Shikoku for a year and a half as support for a local yakuza ally, making his first appearance mid-way through the Haou War. Known in the underworld as "Aoyama of the Hunting Knife," he is feared as a monster-class combatant due to the pure power unleashed from his massive frame and his high level of adaptable combat sense. In daily life, he is a bright and friendly person who never fails to show meticulous care (and flattery) toward his superiors, while remaining a master of communication who treats subordinates like Kotoge frankly. He is particularly close with his contemporary, the cross-dressing hitman Shion Kazuki. He occasionally refers to himself as the "Real Superman."

The Amo-gumi's ultimate cross-dressing hitman. He sets honey traps using genius-level disguise skills. As a result of intense training under Noda's direction, he has become a beauty so stunning it seems like a prank from God. His quick-draw skills with a handgun are exceptionally high. He is a contemporary of Aoyama. His biological sex is male.
