Gansaku Nanbu

Serving as both the manager and boxing coach for Joe, this notorious gambler struggles with a heavy drinking habit and a history of shady dealings. Having previously manipulated Joe into throwing fixed matches within the underground circuit to cover his losses, he now faces massive debts from dog racing. Driven by a desperate need to settle his accounts, he has officially entered Joe into the Megalonia tournament, secretly harboring a deep-seated belief in his fighter's true potential.
