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

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.

The second day of the Summer Tournament begins and Saki has won against Ganeko Mayu from Shitou Suisan. Only Kazunari and Saki are left for the final. During the ten-minute break, Irina approaches Aoi and explains to her that their style of FC was inspired by her, requesting that she watch the next match. Kazunari is confident but Saki slowly starts to dominate the match.

Asuka is facing off with Saki. Asuka uses three consecutive Sonic Boosts and a new technique called Pentagram Force to score the first two points. After scoring a point herself, Saki attacks Asuka but the latter evades all her attacks and scores her third point. Now 3-1, an angry Irina orders Saki to switch off her balancer, allowing her to tap into the full potential of her shoes.
