The C3 Club travels to a remote island for a practice match against the Seto Family team from Kansai, which they manage to win thanks to Yura's quick thinking. After the match, they spend the rest of the evening having a barbecue and setting off fireworks. Later that night, Yura has a nightmare about falling back to her old self and becomes determined to win the next match. The next morning, when everyone's flags are accidentally burned, they decide to have a Capture the Center Flag match using bikini tops instead. As the match gets underway, Sonora notices Yura is a bit more fired up than usual whilst the other members struggle due to the Seto team's strategy of using dual weapons to confuse their numbers. With Yura's help, the C3 Club manage to overcome the Seto team's strategy and win the match, though Sonora does not seem happy about it.

Yura joins up with Meisei's airsoft club, which the C3 Club come to learn of after Aira spots her and informs Karilla. However, Yura becomes upset when Rin assigns her as a medic role during a match that they narrowly lose, feeling she could've won if she was regular attacker. As Rin tells her to figure out the reason for herself, Yura assumes she needs to get stronger and begins training herself intensely, bringing worry to Rento when she comes to visit her. After another medic match, Rin informs Yura that she is ignoring the team and focusing too much on her own victories. During another match, in which one of Meisei's girls injures herself, Yura ignores her in favor of winning the match after she sees that the injured girl is taken care of by other members of Meisei. Rin becomes disappointed in Yura, stating that she is only fighting for her own self-satisfaction, and takes her off the team.
