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...?
Avant la finale tant attendue, les vainqueurs des qualifications des différents districts sont invités à un séjour en station thermale. Quelques surprises sont au rendez-vous.
セイとレイジはリン子やチナたちと一緒に、夏の海へとやってきていた。日頃のバトルを忘れ、海を満喫した一同は、宿泊先である山間の旅館へと向かう。そこには、なんとヤカサ・マオがいた。不穏に感じる一行に、さらなる事件が起こった。トラックが旅館に突っ込んできたのだ。トラックの中から現れたのは、世界大会出場経験者で、灼熱のタツの異名を持つ男であった。果たして、この男の目的とは……！？
诚与岭司成功晋级世界大赛后，便与凛子、千奈等人来到夏日的海滩。众人将对战抛诸脑后，在海滩尽情玩乐，之后他们入住山上的旅舍，却意外遇上一个人——矢坂真生。原来真生也入住了同一间旅舍，更似乎对老板娘的女儿美崎有意思，一直借故亲近。诚等人虽感无奈，也努力尽情享受旅程，但旅舍却显得分外冷清。一行人感到不安，此时再有意外发生，一辆卡车竟然撞进了旅舍。卡车上出现了一个男人，他曾经参加世界大赛，人称「炫热之辰」。这男人到底目的何在…？
