Yura finally meets Sonora, who had returned from a shooting contest in America and becomes impressed by her skills at making onigiri, reminding her of her own marksmen training. Revealing herself to be the president of the C3 Club, Sonora asks Yura if she wants to officially join, but Yura doesn't have enough confidence to agree. Meanwhile, the other members try their own hair-brained schemes to get Yura to join, with little success. Becoming impatient and not giving Yura time to give an honest reply, the members challenge Yura and Sonora to an escort match, in which Yura must safely escort an unarmed Sonora, stating that if they lose, Yura will be forced to join the club. Sonora manages to take Yachiyo down with her own weapon whilst Yura manages to use a clever rouse to get Rento and Honoka to take each other out. As Yura becomes nervous about facing Karila, Sonora tells her to think of her gun as an onigiri and together they manage to take down Karila.

After Sonora is discharged from hospital, Yura confesses to everyone that she violated the 'zombie rule', in which players cannot shoot other players once they have been hit themselves. Yura informed the tournament holders about this, but Rin tells them they didn't violate any rules so their victory stands. Not content with this decision, Yura states she wants to face off against Meisei again, but is met with objection from the others, who can no longer hold back their frustrations with Yura's recent behaviour. Yura confronts Rin over why she kept quiet about her cheating, to which she responds that she just have faith in herself. After seeing a news report of Rin helping to capture the real sniper, stating some words that she heard Sonora use before, Yura calls Sonora to the shrine to ask what her relationship with Rin was. Sonora explains how she and Rin met in America and became friends whilst learning airsoft.
