Chairman operates as the central administrative authority within the narrative, mediating volatile disputes among the Justice, Devil, and Perfect Chojin factions under his formal designation, Harabote Muscle—a title underscoring his role as a stabilizing force. He first emerges during a fragile peace treaty signing between the three groups, leveraging codified diplomacy to enforce compliance.

When the Perfect Large Numbers sabotage the negotiations, he counters by invoking the treaty’s binding authority, only for the faction to dismantle the accord entirely, denouncing its limits on Chojin dominance. Amid escalating clashes, he intercepts impulsive allies such as Terryman, advocating strategic restraint over direct confrontation.

Later, he presides over a ceremonial gathering where children engage with Seigi Chojin, publicly affirming the treaty’s resilience despite simmering discord. This optimism falters as the Perfect Large Numbers assault the event, forcing him to coordinate civilian evacuations while facing the assailants. His command resurfaces when he officiates a decisive post-tournament duel between General Devil and Strong the Budo, rigorously enforcing combat regulations despite the match’s lethal implications.

Across these trials, Chairman’s adherence to systemic order and negotiation remains unwavering, even as factions dismiss diplomacy in favor of raw power. His maneuvers navigate the tension between diplomatic idealism and the brutal pragmatism of factional rivalries, framing leadership as a perpetual balancing act amid unyielding conflict.
