Haruka and the boys have trained hard to prepare for this showdown against Samezuka. After Day 1 of the tournament, Gou and Amakata-sensei treat the boys to a fabulous, carb-rich feast and allow them to take a breather. Meanwhile, Rin is faced with a tough decision as captain of the Samezuka Swim Club. Who will he choose to swim the relay with him?

Upon Rin’s invitation, Haruka finds himself venturing to “a certain country.” Knowing that Haruka has hit a wall worrying about his future, Rin opens up and speaks to him about his own thoughts and feelings. Afterward, Rin quietly asks Haruka what he will do about his own future...

Rin, now living in Australia, trains hard every day with swimmers from all around the world. Then a Japanese guy shows up where his team is training, challenging each of his teammates to races and beating them one by one. Even Rin is surprised when this newcomer reveals his identity...

Hiyori still remembers the first time he saw Ikuya smile. Both boys grew stronger through rigorous training while they studied abroad in America... but seeing Haruka threw Ikuya off his stride. Now Hiyori wishes Ikuya would just forget about Haruka for good.

Nagisa, Rei, and the rest of the Iwatobi Swim Club have come to cheer on their former teammates at the All-Japan Invitational. Makoto tells them the story of how ever since Haruka swam for the first time, he'd been swimming only freestyle.
