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.
That's why I'm his only friend.
Deswegen bin ich sein einziger Freund.
Como es así, solo me tiene a mí como amigo.
Y por ser así, yo
soy su único amigo.
Du coup, je suis son seul ami.
Per questo sono il suo unico amico.
Por isso sou o único amigo dele.
