"If you entrust your life to me, I'll use every last drop of it."
A major yakuza syndicate controlling the Kansai region. They are characterized by an unusually strong bond, with the boss himself embodying the group's philosophy more than anyone else. Operating under a strict meritocracy, the members are all highly skilled individuals who have sworn absolute loyalty to the boss.
○ Basic Philosophy In the Momotsuka-gumi, absolute loyalty to the boss is required of everyone. Because it is a pure meritocracy, there is no seniority, blood relations, factions, or favoritism. Only absolute loyalty and actual ability are tested.
○ The Three Laws
"1. Betrayal is the greatest sin." Any words or actions deemed as betrayal are subject to punishment. However, this does not mean blind obedience; there is a culture of "challenging the boss's opinion at the risk of one's life if he is wrong." Dissent is not betrayal.
"2. Seize everything through strength." Positions such as executive roles are based on merit, so internal coups are permitted. However, cowardly methods to sabotage comrades are prohibited and subject to punishment.
"3. Struggle until death." Failure is not necessarily punished. However, returning from a mission due to giving up—rather than a strategic retreat—is severely reprimanded.
All laws apply to the boss himself. This is why the members respect him from the bottom of their hearts.
○ The Boss The absolute leader who unites these powerful individuals. Sogen has held the seat for years, and no one possesses more strength than he does.

・His view of human value is based on how much one refused to give up until the very end, and he hates people who quit easily. He is most merciless toward traitors.
・He treats those who show absolute loyalty to him more harshly. (He frequently assigns dangerous jobs; this is rooted in trust, so he never performs malicious acts like withholding food.) -> This is not out of malice, but his way of reciprocating the loyalty shown to him. He truly believes that as a leader, his duty is to use up loyalty until the very end.
・Treating absolute loyalty with harshness is his own twisted proof of trust.
・He clearly distinguishes between "throwing life away" and "burning life out," and dislikes meaningless suicide or reckless death.
Raised as the only son of the previous boss, Rinji (died at 67). His mother died shortly after giving birth to him. When he saw his beloved father wither away and die weakly from cancer, he felt disappointed in him. This triggered his hatred for those who give up easily and his obsession with those who resist until the end.
