Eas is the original identity of Setsuna Higashi, and the one that represents her past as a Labyrinth member. Eas was very stubborn and had a great part of pride, refusing to admit defeat to her partners or let them help her. When meeting Cure Peach the first time, Eas swore to be her enemy by telling that they would meet again. Since then, Eas tried her best to defeat Pretty Cure, and in the end, asked Moebius for his help. At her last days, she was given the Nakisakebe cards, since it was obvious that Pretty Cure were getting stronger, and that she herself was having doubts about Labyrinth's goals.
