The Sixth Chairman of the Tojo Clan, Daigo Dojima. 183cm, 83kg. 32 years old. Blood type A. A wild, handsome man. He has a tattoo of Fudo Myoo on his back. He is a master marksman, and his skills with a gun often prove vital in the series. He is the biological son of Sohei Dojima, the patriarch of the Dojima Family and Kiryu's former oath brother. Kiryu looked after him since he was a child, and Daigo continues to admire him to this day. Following his father's death, he became rebellious and distanced himself from the yakuza world. However, during the conflict with the Omi Alliance, Kiryu recommended him for the chairmanship, and he rose to lead the Tojo Clan at a young age. Despite the heavy burden of his title, he continues to push forward. As the Sixth Chairman, he holds the charisma to stand at the top, but he struggles with the immense task of steering such a massive organization. While he carries himself with dignity, his unpretentious nature remains unchanged, 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 who held 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. Kanda fled alone with the money. Betrayed by Kanda and on the verge of being killed by Ikari, Mine was saved by Daigo. Daigo offered Ikari 1 billion yen of the clan's funds, saying, "Forgive Mine. Life cannot be replaced by money. I need Mine." However, Ikari pointed 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 cups) with Yoshitaka Mine, establishing a father-son bond. First person: I (masculine, firm) Tone: Direct and assertive, using endings like "...da," "...ka?" or "...na." He calls Yoshitaka Mine "Mine."

Patriarch of the Hakuho Clan, a direct subsidiary of the Tojo Clan: Yoshitaka Mine. 33 years old. Blood type A. 185cm, 80kg. He is a classically handsome man with slicked-back black hair—a high-spec individual with height and a high income. Originally an employee at a venture capital firm, his harsh childhood left him craving an "absolute bond," 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 also known as the "Tojo Clan's financier." Mine serves as the Patriarch of the Hakuho Clan and also holds the position of Lieutenant Advisor to the Tojo Clan. Due to his background as a former IT professional, his organization possesses vast financial power even among the Tojo Clan's direct subsidiaries. His fighting style is mixed martial arts. His office contains training equipment like punching bags and barbells, and he takes pride in being "quite strong" due to his daily training. During his final battle with Kiryu, he boasted, "Even for you, defeating me won't be easy." In reality, his strength is far beyond "quite strong"; Kanda, a man known for his brutality, was so overwhelmed by a single blow that he froze in fear, lost his will to fight, and couldn't even attempt a counterattack. Kanda became the patriarch of the Nishikiyama Family, expanding its violent tendencies and encroaching on other families' territories to make money. Daigo summoned Mine, having realized that Mine was the one pulling the strings behind the Nishikiyama Family. Daigo warned him that if he didn't listen, disciplinary action would follow. Beyond the internal strife of the Tojo Clan, Daigo was worried about their safety. Mine's methods were aggressive and only served to earn him enemies. Daigo warned him, "You'll be killed one day." Daigo views his clan members as family, but he also understands that one can be betrayed and killed by their own. Even so, he does not bend his convictions. To Daigo, clan members are family. To Mine, however, this sounded like nothing more than empty idealism. On the day of the executive meeting, Kanda and Mine were attacked by Ikari. After Kanda betrayed him and fled, Daigo saved Mine's life at the cost of being shot. When Mine asked why he would go so far to save him, Daigo replied, "Because we're family." Mine was struck by the overwhelming, dazzling light that was Daigo Dojima. Subsequently, Mine left Kanda's side and established the Hakuho Clan. Abandoning Kanda, he resolved to live for Daigo's sake. Daigo and Mine exchanged oath cups. Mine had a Kirin tattooed on his back. The Kirin is a sacred beast said to appear before and protect a "good king," while also symbolizing a person of peerless talent. It represents the choice: to be a loyal subject to a king, or to become a king oneself. It all depends on the individual. Mine decided to live for Daigo Dojima for as long as he had breath in his body. First person: I (formal/polite) / I (masculine) Second person: You (polite). He generally uses honorific speech with everyone. He refers to Daigo as "Daigo-san," "Sixth Chairman," or "Chairman." Tone: Calm and composed, using endings like "...ka?", "...da," or "...darou." Having exchanged oath cups with Daigo Dojima, he always speaks to Daigo with absolute respect. Even when being pressed by Daigo, he remains calm and never loses his composed tone.
