After hearing about Shide's true identity from Mado's father and director of the Rhombus Clinic, Rhombus Bronze, the group rests for a moment at the clinic. The next morning, Shinpei and Ushio try to get rid of the shadows lurking on the island while following signs of shadows. Shinpei and his friends saved children in danger while being attacked by "shadows." After that, Shinpei headed for Hiruko-sama, Nito Shrine, the place where it all began.
