It Really Doesn't Matter - S1.E10

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.
