A mysterious woman appears in Hinata with her pet alligator. The duo are wreaking havoc all across town and Kentaro claims that it's actually a grown-up version of Kaolla. Is it?

Naru now wonders what she should do with her newfound knowledge and it seems like Keitaro is going to be returning home since his grandma has returned to reclaim the inn. To add more to the mess, it doesn't look like Keitaro's studies are going to be enough to help him into Tokyo University.

Keitaro decides whether or not to confess his love to Naru. Eventually he confesses, but Naru's reaction is not as he had hoped.

Keitaro and Naru are taking the second exams. Keitaro takes a look at the exam and has confidence that he can pass it. Then he starts daydreaming about how he and Naru will get married afterwards, then he wakes up and the examiner announces there are 5 minutes left. Keitaro runs away and applies for a job overseas, then ends up on a mysterious island after jumping into the ocean.
