Megumi Morisato, Keiichi's sister, arrives unannounced at the temple and tells Keiichi that she has been accepted as a student at the Nekomi Institute of Technology, and will therefore be moving to the town. She gives Keiichi a specification for her ideal home, threatening to live with Keiichi and Belldandy if Keiichi does not find a home for her. In spite of his conviction that an apartment meeting Megumi's specification will be impossible to find, Keiichi undertakes the task. After a fruitless day's search, Megumi reveals that she would be happy to lower her expectations, and that she never intended to move into the temple anyway. The following day, Belldandy casts a spell, which leads them to an apartment meeting everything on Megumi's wish list. The reason for the apartment's availability, and its low price, is soon revealed in the form of a "third-class" Earth spirit, who attacks Keiichi and Belldandy. After defeating the spirit, Belldandy discovers why it is haunting the apartment. In return for Belldandy's help, the spirit agrees to protect Megumi when she moves in.
