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.

Gli esami sono vicini e i nostri Ronins sono immersi nello studio mentre il Natale si avvicina. Una leggenda dice che se una persona si dichiara per la Vigilia di Natale, potrà vivere felicemente con la persona che ama. In un clima natalizio, sorretto come sempre da splendide animazioni ambientate in una città decorata e grazie ad una e sempre fantastica colonna sonora, Keitaro e Naru vivono questa nuova avventura che segnerà un passo decisivo nel loro rapporto.

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.
