Aired on February 28, 2014

Paper clones of Ragyo and Nui lure Ryuko to Honnouji Academy, prompting her to travel alone despite her reluctance to assist others. After infiltrating the academy’s security systems to locate Satsuki, Ryuko’s allies deduce her plans and board Aikuro's Naked Sol warship to join the conflict. Upon arrival, Ryuko battles Nui, who possesses a Life Fiber body. Ragyo captures Ryuko and compels her to wear Junketsu, initiating a process to rewrite her memories. Simultaneously, Satsuki breaks free from her imprisonment and returns to Nudist Beach on the Sol. When Ryuko, now controlled by Junketsu, arrives on the ship to attack, Satsuki equips Senketsu to confront her former friend.
