As the summer cleansing ceremony approaches, Tatsuo tells Satoru to invite some friends, which leaves him flustered. He continues to practice hard as a member of the kendo club, but he hasn't managed to break the ice with the other members. One day, he gets in a fight with Kosugi, another member, and ends up in a kendo match against Kinugawa, the captain.
But if you make one mistake, 
it turns out all wrong.
Aber wenn man einen Fehler macht, 
wird das Ergebnis komplett falsch.
pero un pequeño error lo arruina.
pero un pequeño error lo estropea todo.
Mais à la moindre erreur, 
il n’est plus bon.
Ma se fai un solo errore, viene male.
Mas um errinho e dá tudo errado.
