After winning a difficult match, the Dachi High sumo club cheers, but Reina feels uneasy and does not join in the cheerful mood. Reina breathes new life into Dachi High through their loose and lax mood, strengthening their resolve to win. Then the team tournament begins. Leading off against Eiga High is Chihiro, who will face Hyodo Masato, who turns out to be his brother.
Sans surprise, c’est le lycée Eigadai qui accède en finale face au lycée Ôdachi. Hinomaru a déjà hâte d’affronter Sôsuke Kuze. Mais avant ça, ses camarades vont devoir briller, et c’est Chihiro qui commencera.
激戦が終わり、勝利を喜ぶダチ校相撲部であったが、その和やかなムードに礼奈は一人違和感を覚える。勝利に浮かれ緩んだ空気に礼奈が喝を入れることで改めてダチ校の気持ちがひとつになったのであった。そしてついに団体戦の決勝戦。栄華大に挑む先鋒・千比路の前に立ちふさがる兵藤真磋人（ひょうどう・まさと）は、千比路の実の兄であった。
Após uma luta disputada, o Colégio Dachi comemora, mas Reina não está no clima de celebração. Ela impõe vigor novo no time e espanta o ambiente descontraído e desleixado, reforçando sua gana de vitória.
