Miyu and her friends are asked to visit the house of Yuko Shigeri, where her brother Kouichi Shigeri is slowly becoming paranoid from a strange mask hung from a wall, which is said to be worn by a witch doctor long ago, though Yuko's father seems to be skeptical about its myths. Larva explains that he met face to face with the mask, a shinma known as Kamen, that had possessed the witch doctor two hundred years ago, but he failed to destroy the mask after killing the witch doctor. Miyu later takes the mask with her and locks herself in a room, where Larva confronts Kamen head-on. After the mask is severed, it is burned to the ground, ending this two-hundred-year-old curse, or so it may seem to be.
