AOKANA: Four Rhythm Across the Blue

Mashiro Arisaka meets a ditzy student, Asuka Kurashina who he later discovers to be a transfer student to Kunahama Academy.

After Reiko leaves, Shion begs Asuka and the others to join the Kunahama's Flying Circus team. At school, Shion's younger sister Madoka congratulates Asuka on scoring against Reiko. Madoka then encourages all of them to join the team. Asuka agrees almost immediately, but Masaya refuses and Misaki says she needs to think about it.

To boost the new recruits' skills, Aoi calls the Takafuji Flying Circus Team to arrange a training camp during spring break. During the last day of the camp, Reiko arranges some practice matches. Asuka is up against Rika Ichinose, a first-year and Speeder at Takafuji and she manages to score a point with an Air Kick Turn, surprising everyone, but ultimately loses the match.

Mashiro has been kept busy by make-up exams recently, causing her to often be late to FC training. Meanwhile, Misaki and Asuka are improving at a fast rate, leaving Mashiro lagging behind. After bumping into Rika by chance, Mashiro asks her to teach her the basics. Training starts the next day, and slowly Mashiro begins to pick up, and finds that she is more suited to be a Speeder like Rika than a Fighter like Misaki.

The Summer Tournament has started, and Asuka is up against a girl named Arika Okoze from Shitou Suisan Academy. Misaki is up against Rika and Mashiro against Reiko. There, Asuka also spots the white-haired girl, Inui Saki from Kairyou Academy, who is playing against Shion. First up is Mashiro's match against Reiko.

The second day of the Tournament has begun, and Asuka is up against Kasumi Kurobuchi from Dougaura High. Asuka wins 6-8 with an angry Kasumi wondering how Asuka can smile so happily during a serious match. Misaki is up against Kazunari next, with the latter taking the lead and avoiding the dogfight that Misaki is looking for.
