Shûsaku Tanokura leads the Tanokura family, one of the two dominant rival factions controlling Kimujuku. His family embodies the wealthier, more established syndicate within the town, increasingly focused on safeguarding their reputation and financial stability amidst the ongoing conflict. Tanokura consistently maintains a composed and calculated demeanor, projecting an image of unshakeable control even as surrounding tensions escalate. This calm, collected approach stands in sharp contrast to the impulsive and volatile leadership style of his rival, Samekichi Shirogane, who commands the opposing Ginzame yakuza clan. The dynamic between these two leaders forms the central axis of Kimujuku's power struggle.

Tanokura's presence fuels the underlying tension in Kimujuku, a place symbolically known as "The Town of the Demon," reflecting the morally complex and dangerous nature of its inhabitants. His actions and decisions as faction leader directly impact the town's stability, shaping the environment encountered by the protagonist, George Kodama. Tanokura embodies one pole of the entrenched conflict defining Kimujuku's social and political landscape.
