Juuzou Kushinada commands the powerful Kushinada clan, rulers of the isolated mountain town of Jouga. As leader of the Kamibito—divine beings dwelling in the old town sector—he enforces strict ancestral laws to preserve a fragile peace with the Ochibito, fallen humans inhabiting the new town. This duty demands he oversee rituals and human sacrifices necessary to appease the region's wolf spirits.

Generations of supernatural conflict have shrouded the Kushinada family in tragedy, fostering a belief among the townsfolk that they carry a curse. Juuzou upholds practices requiring periodic human sacrifices to avert the wolves' wrath, positioning him at the heart of Jouga's darkest secrets. This burden fractures his bond with his daughter, Nemuru Kushinada, who sometimes challenges his unwavering commitment to these harsh customs, despite her own sacred role as the Hakurou Kannon executioner.

Juuzou carries himself with a reserved, serious, and aloof demeanor, often perceived as cold or intimidating. His leadership is defined by an analytical, pragmatic mind, prioritizing order and clan authority above personal ties. He tackles crises directly, relying on keen observation and decisive action grounded in tradition.

The arrival of Hiroshi Kuzumi, a "Temptation" whose intoxicating scent ignites the Kamibito's predatory instincts, unleashes chaos in Jouga. As multiple Kamibito succumb to bloodlust, Juuzou faces an unprecedented threat to the town's stability. He authorizes extreme containment measures proposed by his subordinate, Eiji Kasai, including lethal force against affected individuals like Isuzu Tsumuhana's brother, Issei.

Navigating the ensuing turmoil, Juuzou balances complex tensions between Kamibito and Ochibito factions, his duty to safeguard Jouga's secrets, and his strained family connections. His every action strives to maintain the town's precarious equilibrium, even as external forces like Shunichiro Sakaki seek its destruction.
