第 9 集: 龍套正面迎戰伊拉自殘式的強化，千鶴則在內部構思攻擊策略。

As Ryuko awaits the time for her battle against Ira, Aikuro asks her to drop out of the match, warning that she is not ready to face the Elite Four, to which she naturally declines. The battle soon begins, with Ira activating his Shackle Regalia, attacking himself in order to provide the power needed to transform into Scourge Regalia. Ryuko finds that the Shackle Regalia also serves as an armor protecting its Life Fibers, and is unable to damage the Shackle Regalia without powering up the Scourge Regalia form. Undeterred, Ryuko keeps on attacking, forcing Ira to bring out Scourge Regalia's full power, attempting to forcefully mold Ryuko into a model student. However, Senketsu sets a plan into motion by pulling Ryuko out of her synchronized mode, allowing her to use Senketsu's fangs to break into Ira's uniform and destroy it from the inside using a new form, Senketsu Senjin, winning the match. (Source: Wikipedia)
