Inshun Hozoin, a 17-year-old male student of Kohfukuji Academy aligned with the Kansai faction, carries the legacy of Hōzōin In’ei as his S-class Toushi successor. Born on November 13th and standing 1.82 meters tall, his silver hair and brown eyes mirror his striking presence. Initially defined by pride and overconfidence, his unwavering belief in his prowess obscures awareness of his flaws.

During the Kansai faction’s assault on Seito Gakuen, Inshun clashes with Kan’u in a decisive duel. Though he enters as an S-class combatant, Kan’u’s mid-battle ascension to the same rank overwhelms him, culminating in his defeat. The loss becomes a catalyst for introspection, dissolving his arrogance into humility. Returning to his dojo, he overhears his students’ candid criticisms but suppresses his instinctive anger, channeling their words into a resolve for growth. This measured response baffles his pupils, slowly transforming their skepticism into deepened respect.

His journey confronts further trials when Himiko, a seeker of spiritual relics like magatama and tsuba, challenges him. Despite fierce resistance, her superior combat skill prevails. His students rally to aid him, yet their collective effort falls short, underscoring both Inshun’s lingering vulnerabilities and the escalating tensions surrounding mystical artifacts.

Inshun’s arc pivots from brash self-assurance to quiet perseverance. Each defeat fractures his former hubris, revealing a disciplined dedication to refinement. His evolving demeanor—marked by restraint and introspection—contrasts sharply with his past impulsivity, positioning him as a nuanced figure within the Kansai faction’s struggles and the shadowy wars over ancient spiritual objects.
