In addition to deleting the memories that Ruru had made with everyone, Criasu member Listle reprograms her with a battle protocol. Meanwhile, Harry explains that Ruru is an android sent to spy on them, but the girls remain determined to save her. Following her reprogramming, Ruru equips a battle suit and confronts the Cures, using their battle data to predict their moves. As Ruru tries to obtain more data from the Cures, she starts to regain the memories that she herself prevented from being deleted. With help from Hana, Ruru gains a human heart and turns against the Criasu Corporation. As Ruru finally rejoins the others, Emiru discovers the Cures' secret identity.
