Sei and Reiji have now earned their place in the World Tournament. Together with Rinko and China, they go to the summer sea, where they can all forget the usual battles and enjoy the seaside. They head for an inn in the mountains, only to find Mao Yasaka there—he too has come to stay at the inn. What’s more, it looks like he’s taken an interest in Misaki, the landlady’s daughter, and one way or another he keeps making passes at her. Nonetheless, Sei and the others try to enjoy their stay at the inn, but it seems that the inn is in some kind of decline. They begin to feel uneasy as more incidents occur, and then a truck crashes into the inn. From the truck emerges a man known as Blazing Tatsu, a veteran of previous World Tournaments. What could his objective be…?
