This Impatience an Awakening - S2.E5

Futase explains she is fully aware of WIXOSS' secrets, but still desires to battle, agreeing to tell what she knows if someone beats her in a battle. With Chiyori already having two losses, Ruko steps in to battle against Futase and her LRIG, An. With Ruko struggling to bring out her full potential, Iona tells her that she needs to get serious if she has any hope of saving Tama. With this new determination, Ruko manages to grow Iona into a previously impossible Level 5 LRIG and win the battle. Futase then reveals that she herself was a LRIG whose Selector was the real Fumio, who initially wanted to achieve her wish by her own esteem. She eventually gave into battles and soon became an Eternal Girl while Futase took Fumio's place, during which she overheard Mayu mention about a "Girl of Black" and a "Girl of White", which Fumio believes that "Girl of Black" was referring to Iona.
