S1·E21 The Fourth: Kirio

Kirio pays a visit to Ushio to take the scythe from him. But they are interrupted when Kuragi, an insect like yōkai, who is avatar of Hakumen no Mono attacks the Kōhamei Sect headquarters, unstoppable by any. Ushio and Kirio are taken there by Shigure where Ushio meets Mikado Hizaki. Later, as Ushio falls after failing to defeat Kuragi, Mikado Hizaki freezes the monster and Kirio finishes it off. Mikado Hizaki dies after exhausting her powers. Afterwards, we see Kirio telling his mother how he finished the monster himself, and that no one believes him when he says that they don't need the Beast Spear to defeat Hakumen no Mono. She gives him the Beast Spear's red cloth and tells him that if no one believes, it is ok to break the spear to show them so.
