Should a Commander Be Hard of Heart?
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.
