They ask what he is doing, and Jibanyan says he has moved in. After Whisper fails to get anything out of him, Keita asks why he has moved in, and Jibanyan reveals that his old resting place has been filled up by other ghostly cats who need a home. Keita agrees to let Jibanyan live with him, as they are friends, but soon discovers that Jibanyan's behavior is rude and disrupting his mother and father's lives, using a large paper fan to try to keep him in line, and both he and Whisper are at their wits' end. Keita's parents reveal they have hired an exorcist to try to remove the evil spirits from the house, and his prayers actually begin to work on Jibanyan and Whisper, sending them away to heaven. Keita tries to disrupt the exorcism, to the best of his ability, and only succeeds by convincing the exorcist and his parents that the evil spirits are gone from his room. The next day, Jibanyan has turned a new leaf, and has cleaned the house top to bottom to apologize.
