After what seems like years of studying to get into prestigious Tokyo University, Keitaro finally gets a break. The whole gang from Hinata House takes a trip to the beach for a summer of fun in the sun.

If he doesn't find a way to win back her affections soon, he may lose her for good to his romantic rival, Seta-san.
