S1E6 This Just Can't Be Right

Homura suddenly materializes on the battlefield where Sayaka and Kyoko are fighting. Without warning, she steps in and takes Sayaka down with just one strike, leaving her unconscious. Witnessing this, Kyoko immediately tenses up, wary of Homura's intentions. Rather than engage, she chooses to withdraw, bringing the confrontation to an abrupt halt.
