Synopsis
At the start of a new school year, Haruka Nanase and the others meet up with Rin Matsuoka at Samezuka Academy for an event to send off the third year members, where they end up getting roped into a freestyle relay against the school.

Afterwards, as the Iwatobi Swim Club struggles to recruit new members, Goro reveals he has reformed the Iwatobi Swimming Club, now known as Iwatobi SC Returns, giving the guys a chance to use the indoor pool prior to its opening.

Later, Rin, who has been made captain of the Samezuka Swim Club, participates in a race against Haruka, managing to tie for the lead.

Later that evening, Haruka and the others invite Rin to the school pool, which they have cleaned and filled with cherry blossoms so that Rin could swim in it, since it is something that he wanted to do when he was younger. However, the unexpected rain ruins the opportunity.

The next day, Rin is surprised to find out that an old acquaintance of his, Sosuke Yamazaki, has transferred into his class.
