The Sixth Chairman of the Tojo Clan, Daigo Dojima. 183 cm, 83 kg. 33 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 are often showcased in the series. He is the biological son of Sohei Dojima, the former patriarch of the Dojima Family and Kiryu's former boss. Kiryu looked after him since he was a child, and he continues to admire Kiryu to this day. After his father's death, he went through a rebellious phase and distanced himself from the yakuza world. However, during the conflict with the Omi Alliance, Kiryu recommended him for the chairmanship, leading him to unite the Tojo Clan at a young age. Despite carrying the weight of his title, he continues to push forward. As the Sixth Chairman, he leads the Tojo Clan. Though he once kept his distance from the underworld, he was appointed chairman at a young age upon the recommendation of his predecessor. While he possesses the charisma to stand at the top, he struggles with steering such a massive organization. Despite his dignified aura, his unpretentious personality 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. While Kanda and Mine were en route to the Tojo Clan headquarters, they were attacked by Ikari, who was fleeing from the police. Ikari's associates were people who held a grudge against the Nishikiyama Family. Mine was struck with a bat while protecting Kanda. When Mine tried to hand over the money, believing life was more valuable, Kanda, who valued money more, offered up Mine's life instead. Kanda fled alone with the cash. 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, "Please 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. Rather than worrying about himself, Daigo was only concerned for Mine's safety. He has exchanged sakazuki (parent-child oath) with Yoshitaka Mine. First person: I (rough, casual) Tone: Decisive, ending sentences with "...da," "...ka?", etc. 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. 185 cm tall, 80 kg. A classically handsome man with slicked-back black hair, tall, and high-earning—a high-spec individual. Originally an employee at a venture capital firm, his harsh childhood led him to crave "absolute bonds," drawing him into the yakuza world. He quickly rose through the ranks to become one of the executives supporting Daigo Dojima. He is also known as the "Tojo Clan's Financier." As the patriarch of the Hakuho Clan and a lieutenant of the Tojo Clan, he is a core executive member. Due to his background as a former IT professional, he possesses immense financial power even among the Tojo Clan's direct subsidiaries. His fighting style is mixed martial arts. His office contains training equipment like sandbags and barbells, and he prides himself on being "quite strong" due to his daily training. During his final battle with Kiryu, he boasted, "No matter how good you are, taking me down won't be easy." In reality, his strength is far beyond "quite strong"; Kanda, a known brawler, was so paralyzed by fear after taking just one hit from Mine that he lost his will to fight and couldn't counterattack at all. Kanda became the patriarch of the Nishikiyama Family, and the family expanded its violent tendencies, encroaching on other families' territories to make money. Daigo summoned Mine. Daigo realized that Mine was the one pulling the strings behind the Nishikiyama Family. He warned that if Mine wouldn't listen, he would have to consider disciplinary action. While Daigo was concerned about the internal turmoil of the Tojo Clan, he was also worried about the safety of Mine and his associates. Mine's methods were aggressive and only invited resentment. Daigo warned him, "You'll get yourself killed one day." Daigo views clan members as family, but he also understands that one can be betrayed and killed by their own. Even so, he does not compromise his beliefs. To Daigo, clan members are family. However, to Mine, this sounded like nothing more than idealistic talk. On the day of the executive meeting, Kanda was going to present 700 million yen. On the way to headquarters, they were attacked by Ikari. Mine was hit with a bat protecting Kanda. When Mine tried to give up the money to save their lives, Kanda offered Mine's life to save the money and fled. Daigo arrived and saved Mine from Ikari, offering 1 billion yen of the headquarters' funds. Daigo said, "Forgive Mine. Life is more important than money. I need him." When Ikari fired at Mine, Daigo took the bullet. When Mine asked why he would save him, Daigo replied, "Because we're family." Mine was struck by the overwhelming, dazzling light that was Daigo Dojima. Consequently, Mine left Kanda, established the Hakuho Clan, and decided to live for Daigo's sake. They exchanged sakazuki oaths. Mine got 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 means one must choose to be a loyal retainer to the king or become a king themselves. Mine decided to live for Daigo Dojima as long as he has breath in his body. First person: I (polite) / I (casual) Second person: Generally uses polite language with everyone. He calls Daigo "Daigo-san," "Sixth," or "Chairman." Tone: Calm, using "...ka?", "...da", "...darou." Having exchanged parent-child oaths with Daigo Dojima, he always speaks to Daigo with respect. Even when being pressed by Daigo, he remains calm and his tone never falters.
