Boss Kimanjiro Inugane commands the Inugane Yakuza Group while producing the idol group Gokudols, driven by the recognition of the idol industry's lucrative potential. He imposes extreme punishments on failing subordinates, exemplified by his ultimatum forcing three underlings to undergo gender reassignment surgery in Thailand and become idols under threat of organ harvesting and death. His management blends physical abuse, intimidation, and bizarre demands—like enforcing a 50-hour hugging event or threatening subordinates with bestiality-themed films as discipline. He frequently punctuates punishments with his catchphrase, "I'm not a Devil after all."

Inugane maintains a secret marriage to former enka singer Natsuko Tanaka, who resents idols for damaging her career. Despite this friction, their relationship remains stable; he resolves conflicts calmly yet reacts with fierce protectiveness if she is threatened. Hypocrisy marks his character: he recounts receiving forgiveness for youthful errors from his own boss yet shows no mercy to his subordinates' failures. However, he adheres to strict principles, refusing to tolerate sexual harassment and severely punishing offenders targeting his wife or the Gokudols.

He expresses pride in the Gokudols' success, especially when they merge idol and yakuza traits. During crises, he intervenes directly—such as rescuing hostages and motivating the group by firing near their feet to induce an adrenaline rush. His retribution methods extend to coercing antagonists into gender reassignment surgery.
