Original air date: August 7, 2003

Summary:
The father of Naota's classmate Eri Ninamori, as well as the mayor of Mabase, is caught up in a scandal involving an alleged separation with her mother. Ninamori is more focused on the class' upcoming play, Puss in Boots, in which she plays the lead opposite Naota, who was voted to play the cat. Naota is unenthusiastic about his casting and skips the day's rehearsal. Upon meeting with Mamimi, she discovers that he now has cat ears growing from his head. Ninamori retreats to a train station to get away from the media circus that has developed outside her home, where Naota finds her. Haruko comes racing down the street, and loses her Vespa when she tries to avoid hitting a cat. The Vespa slams into Naota, knocking him into Ninamori. Kamon invites her to spend the night at the Nandaba residence due to the current turmoil at her home, and while in Naota's room, she reveals that she rigged the class votes to have him cast as the cat. The next day, the two get into an argument over the play. After Ninamori angrily reveals Naota's cat ears, he retaliates by revealing her vote rigging. This triggers the emergence of a massive creature from her head, which Haruko and Canti manage to defeat with the help of curry. The class goes through with the play.
