Shusaku Tanokura presides as patriarch and leader of the Tanokura family, a powerful faction entrenched in the rural town of Kimujuku. The family’s longstanding dominance, built on control of local mining and tourism enterprises, contends with rival factions seeking to erode their authority. Renowned for his methodical composure, Shusaku stands in stark contrast to Samekichi Shirogane, the brash leader of the rival Ginzame yakuza clan. His composed authority and reputation as an ostensibly flawless leader anchor the family’s operations against mounting internal dissent and external threats.

To safeguard his family’s interests, Shusaku adopts ruthless pragmatism, such as recruiting outsiders like George Kodama to protect his daughter Miyuki—a tactical move reflecting his willingness to exploit external skills against adversaries. Though publicly embodying unshakable stability, he steers through lingering tensions from Kimujuku’s violent past, including unsolved mysteries surrounding a gold bullion train heist. His measured dealings with figures like Sanae Araki suggest veiled alliances and intricate stratagems woven into the town’s fractious power struggles.

As a stabilizing pillar amid turmoil, Shusaku’s calculated choices occasionally expose cracks in his impervious facade. His dynamic with Miyuki illustrates the weight of familial duty, while his rivalry with the Shirogane clan showcases his deft maneuvering to retain control. The scope of his influence and decisions within the current narrative implies, but does not explicitly detail, a history shaped by calculated ambition and entrenched loyalty to his lineage.
