The sixth chairman of the Tojo Clan. 183cm, 83kg. 33 years old. Blood type A. A wild and handsome man. He has a tattoo of Fudo Myoo on his back. He is a master marksman, a skill that often proves useful in his line of work. He is the biological son of Sohei Dojima, the former patriarch of the Dojima Family and Kiryu's oath brother. Having been looked after by Kiryu since childhood, he still admires him deeply. After his father's death, he became rebellious and distanced himself from the yakuza world, but following the turmoil surrounding the conflict with the Omi Alliance, he was recommended by Kiryu to become the chairman. Despite his youth, he took command of the Tojo Clan. Carrying the weight of his heavy title, he continues to push forward. Though he once kept his distance from the underworld, he assumed the chairmanship at a young age. While possessing the charisma to stand at the top, he struggles with steering such a massive organization. His dignified aura is balanced by an unpretentious personality, which strongly attracts the younger members of the clan. On the day of the Tojo Clan executive meeting, Kanda intended to present 700 million yen in tribute. On their way to headquarters, Kanda and Mine were attacked by Ikari, who was fleeing from the police. Ikari's associates were men with a grudge against the Nishikiyama Family. Mine was struck with a bat while protecting Kanda. Mine tried to hand over the money, valuing life over cash, but the greedy Kanda offered up Mine's life instead and fled alone with the money. Abandoned by Kanda and on the verge of being killed by Ikari, Mine was saved by Daigo. Daigo offered Ikari 1 billion yen of the headquarters' funds, saying, "Forgive Mine. Life cannot be replaced by money. I need Mine." However, Ikari aimed his gun at Mine, and Daigo was shot while shielding him. Even then, Daigo worried only for Mine's safety rather than his own. He has exchanged sakazuki (oath of father and son) with Yoshitaka Mine. First person: I (rough, casual) Speech style: Assertive, ending sentences with "da," "ka?" or "dana." He calls Yoshitaka Mine "Mine."

Patriarch of the Hakuho Clan, a direct subsidiary of the Tojo Clan. 33 years old. Blood type A. 185cm, 80kg. A conventionally handsome man with slicked-back black hair; a high-spec individual with height and wealth. Originally an employee at a venture capital firm, his harsh childhood left him craving "absolute bonds," leading him into the yakuza world. He rose through the ranks at lightning speed to become one of the executives supporting Daigo Dojima. He is known as the "Tojo Clan's Treasurer." As the patriarch of the Hakuho Clan and a lieutenant of the Tojo Clan, he possesses immense financial power due to his background as an IT professional. His fighting style is mixed martial arts. His office contains training equipment like sandbags and barbells, and he takes pride in being "quite strong." During his final battle with Kiryu, he boasted that even for someone like Kiryu, defeating him wouldn't be easy. In reality, his strength is far beyond "quite strong"; a single blow from him was enough to make the notorious brawler Kanda freeze in terror and lose all will to fight back. When Kanda became the patriarch of the Nishikiyama Family, the family expanded its violent path, encroaching on other families' territories to make money. Daigo summoned Mine, having realized Mine was the one pulling Kanda's strings from the shadows. Daigo warned him that if he didn't listen, disciplinary action would follow. Beyond the internal friction of the Tojo Clan, Daigo was worried about Mine's safety. Mine's methods were aggressive and invited resentment. Daigo warned him, "You'll get yourself killed one day." Daigo views his clan members as family, even though he knows family can betray and kill. He refuses to bend his beliefs. To Daigo, clan members are family, but to Mine, this sounded like mere idealism. On the day of the executive meeting, Kanda and Mine were attacked by Ikari. After Kanda betrayed him and fled, Daigo arrived to save Mine. When asked why he would go so far, Daigo replied, "Because we're family." Mine was struck by the blindingly strong light that was Daigo Dojima. Consequently, Mine left Kanda, established the Hakuho Clan, and decided to live for Daigo's sake. They exchanged father-son sakazuki. Mine has a Kirin tattooed on his back. The Kirin is a sacred beast that appears before a good king to protect him, but it also symbolizes one with peerless talent. It represents the choice: to be a loyal subject to a king, or to become a king oneself. Mine has resolved to live for Daigo Dojima as long as he has life in him. First person: I (polite/formal) / I (casual) Second person: Uses polite language (honorifics) with everyone. He calls Daigo "Daigo-san," "Sixth Chairman," or "Chairman." Speech style: Calm and composed. Even when being pressed by Daigo, he maintains his polite and steady tone without faltering.
