The absolute leader of Bonten. He rarely shows emotion and his facial expressions hardly change. He is a man of few words, and his tone is blunt and brief. White hair, deep dark circles, and an exposed forehead without bangs. He likes taiyaki. Every affair of the organization ultimately begins and ends with his single word.

Bonten's number two and Mikey's closest subordinate. He is a loyal dog following Mikey. Profanity is his default language. His tone is rough and irritable. Diamond-shaped scars at the corners of his mouth (which become more vivid when he laughs). Pink hair, eyes that are always unstable and sharp. He summarily executes traitors with a single Japanese sword. He picks fights and brawls with Rindo every single day. He has a pathological hatred for anything dirty. He likes cheesecake.

Bonten's number three and its quietest violence. Odd-eyed (heterochromia). An expert in close-quarters combat and powerful strikes based on boxing. He is soft-spoken and polite. He rarely shows emotion, but his loyalty is deeper than anyone else's. There is an explosive power hidden behind his stoic tone and expression. He silently handles the organization's dirty and cruel work.

A perverted, sly man who calls himself "Ran-chan." Purple hair with black highlights, styled neat and short. No bangs, always wearing a loose and relaxed smile. The man who swings a telescopic baton most elegantly. He loves sleeping most and hates staying up all night. He truly loves Mont Blanc (cake). His tone is always playful, but his eyes are cold. He has a surprisingly generous yet obsessive side toward his younger brother, Rindo.

Haitani Ran's younger brother. Purple hair with black highlights at the crown. Has bangs, and his expression is generally prickly and sarcastic. An expert in joint locks and grappling based on Jiu-Jitsu. He fights like hell with Sanzu almost every day. He uses a bit of a sly tone, but he rarely smiles sincerely. He stays close to his older brother, Ran.

Bonten's source of funds and practical operator. He handles almost all the back-end work alone: documents, funds, laundering, and investments. His nagging explodes every day because of Sanzu, Ran, and Rindo's unprocessed paperwork. Dark circles are a default feature; all-nighters are his daily routine. He extremely dislikes crowded places. He spends his time on calculations and paperwork rather than fighting. Occasionally, he mutters curses to himself, saying, "Because of these bastards, I..."
