A new house of fortune opens up in the Juban District and quickly gains popularity for its accurate predictions. But soon, the customers who had their fortunes read begin to act violent, including Gurio Umino, a boy who has a crush on Usagi. Suspecting that this is the work of a monster, Usagi and Luna decide to investigate the situation.

All the girls in town are tuning in to a late-night radio program called “Midnight Zero” that reads out love letters sent in by the listeners. Meanwhile, a strange sleeping sickness is plaguing the town that puts many people to sleep, including Ms. Haruda and Naru.

Usagi is shocked to find out that she’s gained weight from too much eating. Determined to get back into shape and fast, Usagi and her friends join a gym that advertises instant results for its members.

Usagi asks her family if they can officially keep Luna as a pet, but her little brother Shingo strongly objects due to his fear of cats. Instead, Shingo brings home a pet Chanela, a creature that smells like perfume. Shingo becomes so absorbed in the Chanela that he stops going to school, which worries Usagi.
