Go in Guns Blazing. - S1.E12

Sonora challenges Yura to a one-on-one match, matching each other move for move and rekindling their excitement for airsoft. In the middle of the match, Rento comes by to give Yura some more ammo, earning her thanks for inviting her, whilst Karilla comes to support Sonora, with the entire club soon getting involved and turning the game into a free-for-all. As the day comes to a end, Yura urges everyone to keep fighting til the last pellet is fired, bringing everyone into her dream world where they fight against the entire academy. With the day finally coming to an end, Sonora invites Yura and the others to come visit her any time. After Sonora leaves for America, Yura takes some initiative and invites some other students to join the C3 Club.
