Tachiji, a member of Noshiga’s trio, sports a blonde afro and dons glasses over his fox mask during the perilous game of Otokoyo. Alongside Noshiga and Suku, he joins initial discussions about chilling rumors tying child disappearances to demonic forces linked to the game. As the group navigates shadowed tunnels, Tachiji voices unease about their surroundings, urging caution and chastising Noshiga for reckless noise that might draw unseen threats.

When a dormant demon statue awakens after Noshiga’s aggressive provocation, chaos erupts. Fleeing the enraged entity, Noshiga accidentally shoves Tachiji down, leaving him unconscious. Reviving briefly in the aftermath, Tachiji becomes Kimotori’s first captive—eliminated swiftly from the game. His abrupt capture, marked by vulnerability and misfortune, cements his role as a secondary figure whose swift exit starkly frames the lethal consequences awaiting those who underestimate Otokoyo’s dangers.
