The Supernatural Studies Club meets Miyamura's sister, Leona, in their search for the seventh witch. She has dropped out of school in order to escape from that witch's power to erase memories. The instant one learns her name, all of their memories related to witches will be erased.

воспоминания, связанные с ведьмами?
