In "Toilet no Hanako-san - 04", Nene and his friends continue to unravel the mysteries surrounding Hanako-san, delving deeper into the dark history of their school. Meanwhile, in "Kukkyou Taimashi - 04", Kaito faces a new challenge as he confronts a powerful entity that threatens the balance between the human and spirit worlds.

Episode 04 serves as the climax of the first major narrative arc. Following initial skirmishes where Kongou systematically defeats various regional spirits, the power dynamic drastically alters. The Defeat and Absorption of the Urban Legends
