20

After hearing word of a student named Ruri Sone having survived a house fire, Miyu is invited to spend time with her there. Miyu meets Hiroshi Sone, Ruri's soft-spoken father and former paleontologist. The next day, Ruri explains to Miyu that Hiroshi received a butterfly as a gift and let it roam free in the greenhouse, yet she believes that her father has become obsessed with this butterfly since he goes to the greenhouse every night just to see it. This butterfly has actually taken the form of a fairy, making Hiroshi's dreams come true, but Miyu interrupts and ends this cycle. It is revealed that Ruri's mind has been inhabited by a shinma named Maji-Kan, who distorted Hiroshi's thoughts of her being a fairy. When Miyu sends Maji-Kan into the darkness, Hiroshi runs into the flames and is burned alive. Miyu then puts Ruri into an eternal sleep so that she will never feel lonely ever again.
