Ep. 9: Ryuko faces Ira's self-inflicted power-up while Senketsu devises an internal attack strategy.

Ryuko prepares for her match against Ira, but Aikuro advises her to withdraw, claiming she is unprepared to fight the Elite Four. She refuses his warning, and the duel commences. Ira activates his Shackle Regalia, injuring himself to generate the energy required to transform into Scourge Regalia. Ryuko discovers that the Shackle Regalia protects its Life Fibers, making it impossible to damage without first powering up the Scourge Regalia form. Despite this obstacle, she continues her assault, compelling Ira to unleash the full strength of Scourge Regalia to forcibly mold her into a model student. Senketsu then executes a plan by removing Ryuko from synchronized mode. This allows her to utilize Senketsu's fangs to breach Ira's uniform and destroy it from within using a new form called Senketsu Senjin, securing her victory in the match.
