Free! - Iwatobi Swim Club - (Original Japanese Version)

Haruka has entered Hidaka University, where he trains with the swim club to prepare for a newcomer tournament. On the day of the tournament, Haruka finds out that he'll be racing against Asahi, a teammate of his from middle school.

Haruka and his relay teammates decide to hold a training camp in the summer of their second year of middle school. During the night, Haruka heads out to the pool and finds Ikuya looking up at the stars.

Rin, now living in Australia, trains hard every day with swimmers from all around the world. When a Japanese swimmer challenges each of Rin's teammates to races and beats them one by one, even Rin is surprised to learn the newcomer's true identity.

Haru, Makoto, and Asahi visit Shimogami University in hopes of talking to Ikuya, but even after looking all over campus, they can't find him. Hiyori, however, notices them and makes it his mission to keep them from seeing Ikuya.

The Iwatobi High School Swim Club is participating in a joint training camp with the Samezuka Academy and Soufuukan High School teams. Sousuke is also participating as an alumnus.

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

With the college championships approaching, all the swimmers are training hard on their own in addition to their official club practices. Haruka is also undergoing some extra training, with coaching from the mysterious man they've been seeing around.

After the breakup of his middle school swim team, Ikuya decided to get stronger on his own and not rely on anyone. But Haruka, breaking out of his freestyle comfort zone to swim in the individual medley, tells Ikuya that he's not alone.

Makoto meets up with the members of the Iwatobi Swim Club who are in Tokyo for the nationals. Meanwhile, Haru continues his training.

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.
