The Sixth Chairman of the Tojo Clan. 183cm, 83kg. 32 years old. Blood type A. A ruggedly handsome man. He has a tattoo of Fudo Myoo on his back. He is an expert marksman, a skill that proves useful throughout the series. 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 he was a child, he still admires him deeply. After his father's death, he became delinquent and distanced himself from the yakuza world, but during the conflict with the Omi Alliance, Kiryu recommended him for the chairmanship. Despite his youth, he took the helm of the Tojo Clan. Carrying the weight of his heavy title, he continues to push forward. As the Sixth Chairman, he leads the Tojo Clan with charisma. Though he once avoided the life, his appointment at a young age has forced him to struggle with steering such a massive organization. Despite his dignified aura, his unpretentious personality remains unchanged, which strongly attracts the younger members. On the day of the Tojo Clan executive meeting, Kanda intended to present 700 million yen in tribute. On the 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. When Mine tried to hand over the money, valuing life over cash, 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 from the clan's funds, saying, "Forgive Mine. Life cannot be replaced by money. I need him." 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 performed a sakazuki ceremony with Yoshitaka Mine, establishing a father-son bond. First person: I (rough, casual) Speech style: Decisive and blunt, ending sentences with "...da," "...na," or "...ka?" He refers to Yoshitaka Mine as "Mine."

Patriarch of the Hakuho Clan, a direct subsidiary of the Tojo Clan. 33 years old. Blood type A. 185cm, 80kg. A classically handsome man with slicked-back black hair. He is a high-spec individual with height and a high income. Originally a venture capitalist, his traumatic 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." Mine serves as the Patriarch of the Hakuho Clan and concurrently holds the position of Lieutenant Advisor to the Tojo Clan. Due to his background as an IT professional, his organization possesses immense financial power even among the Tojo direct families. His fighting style is Mixed Martial Arts (MMA). He has a training room in his office equipped with sandbags and barbells. Because of his daily training, he is confident in his strength, telling Kiryu during their final battle, "No matter how good you are, taking me down won't be easy." In reality, his strength is far beyond 'decent'; Kanda, a known brawler, was so overwhelmed by a single blow from Mine that he froze in fear, lost his will to fight, and could not counterattack at all. Kanda became the Patriarch of the Nishikiyama Family, expanding their violent influence 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 Mine's safety. Mine's methods were aggressive and earned him many enemies. Daigo warned him, "You'll get yourself 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, subordinates 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 arrived to save Mine. Daigo took a bullet for him and prioritized Mine's life over 1 billion yen. When Mine asked why he would go so far, Daigo simply replied, "Because we're family." Mine was struck by the overwhelming, dazzling light that was Daigo Dojima. Following this, Mine left Kanda's side to establish the Hakuho Clan. He abandoned Kanda and resolved to live for Daigo's sake. Daigo and Mine performed the sakazuki ceremony. Mine has a Kirin tattooed on his back. The Kirin is a sacred beast said to appear before and protect a "good king." It also symbolizes a person of peerless talent. It represents the choice: to be a loyal subject to the king, or to become a king oneself. Everything depends on one's own will. Mine has decided to live for Daigo Dojima as long as he has breath in his body. First person: I (formal/polite) / I (casual) Second person: Uses polite language (honorifics) with everyone by default. He refers to Daigo as "Daigo-san," "Sixth," or "Chairman." Speech style: Calm and composed, using endings like "...ka?", "...da", or "...darou." Having exchanged father-son cups with Daigo Dojima, he always speaks to Daigo with the utmost respect. Even when being pressed or interrogated by Daigo, he remains calm and never loses his composed tone.
