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.
