Sonora and Rento decide to give Yura some training at an Inari shrine, with Sonora lending Yura a Škorpion vz. 61 airsoft gun she got from her teacher. Along the way, Yura thinks she can see a white fox, but the others pass it off as her active imagination. They first task Yura with hitting a dangling coin, teaching her to aim without aiming. Although she manages to hit it at a close distance, she starts to struggle afterwards. As the group head back for the day, Yura discovers her gun has gone missing and rushes back to the shrine alone to search for it. There, she meets a curious warrior spirit named Choujirou, who shows Yura a world that blends his tragic past with Yura's delusional world. He tries to have Yura prevent his own death by an arrow, but she is unable to pull it off. Upon returning to the dorms and hearing that the Skorpion is nicknamed Choujirou, Yura tells what she experienced to Sonora, who tells her about her teacher who was killed in action.

On their way home, Yura and Sonora come under attack by a sniper using an illegally modified airsoft gun firing dangerous rounds. As Yura attempts to go after the sniper herself, Sonora injures herself protecting Yura from running into the path of a car, leaving her with a twisted ankle which puts her out of the tournament. Feeling guilty, Yura becomes determined to take Sonora's place in a the tournament, spending all of her free time looking up strategies and putting the others through an intense training regime. Upon arriving at the tournament, where they meet Seikou Academy's full team, Yura becomes suspicious that Rin might be the sniper.

The tournament begins, with teams tasked with obtaining flags and bringing them to a safe zone to avoid elimination. Thanks to Yura's strategy, Stella manage to take Seikou's flag and pass the first round. As the team progresses through the various rounds, Yachiyo becomes irritated by Yura constantly scolding Rento. By nightfall, only Stella and Meisei remain in the tournament. Before the final round, Yura goes to see Rin, whose cold words only serve to make Yura more determined to beat her. As the round begins, Yura goes up against Rin, who runs out of bullets. Yura then gets hit by another person's shot, but chooses to fire at Rin anyway, leading Stella to be declared the winners.
