Synopsis
Makoto starts helping Goro at Iwatobi Swimming Club, acting as a swimming coach.

Meanwhile, Sosuke decides to help coach Nitori to improve his swimming.

As Makoto notices one of his students, Hayato, struggling with swimming without a kick board, he discovers that his brother is Kisumi Shigino, an old classmate from his and Haru's middle school. As the two reminisce, Kisumi explains to Makoto how Hayato developed a fear of swimming after he nearly drowned after falling off a boat.

Told by Haru to think over his own experiences of learning to swim, Makoto teaches Hayato how to do the backstroke, helping him to overcome his fear. As Makoto's time as a coach comes to an end, he and Haru learn from Kisumi that Sosuke had recently obtained an injury to his shoulder and had been competing in tournaments in spite of it.
