Takahito Misumi is a high-ranking executive board member and chairmanship candidate within the Doushinkai yakuza organization, having previously led the Shinseikai group. He stands 180 cm tall, weighs 76 kg, and possesses brown eyes. His slicked-back black hair shows signs of graying, and wrinkles mark his eyes and forehead with age. Extensive traditional Japanese tattoos cover his body. Misumi favors formal attire and smokes Parliament cigarettes.

Intelligent and perceptive, Misumi also demonstrates a capacity for genuine affection, evident in his relationships with his deceased wife, her son Amou Shizuma (his personal secretary), his bodyguard Kurobane (considered his "other half"), and Yashiro. Despite this warmth, multiple sources document a history of extreme violence. This duality shapes his leadership style, intertwining loyalty and intimidation.

Deeply embedded in yakuza structures, Misumi recruited Yashiro into the Shinseikai shortly after Yashiro graduated high school, setting him on the path to becoming a boss. Their relationship evolved from mentor-protege to lovers, later settling into a brotherly dynamic. In yakuza terms, Misumi is Yashiro's foundational "parent" figure. His rise within Doushinkai did not lessen his persistent favoritism toward Yashiro.

Currently, Misumi awaits a meeting to compel Yashiro into service, citing the Doushinkai boss's illness and senior ranks' hostility toward Yashiro. He advises Yashiro to dismiss his bodyguard, Chikara Doumeki, expressing open dislike for Doumeki's presence through intimidation masked as jokes. Misumi views Doumeki as an unwelcome influence in both the organization and Yashiro's life.

His relationship with bodyguard Kurobane encompasses both protection and significant intimacy, a distinct bond absent elsewhere. Personal trivia includes preferences for sushi, whale meat, mahjong, clubs, golf, and luxury vehicles like Mercedes-Benz. His blood type is O, and his birthday is August 21.
