May-Yu's younger twin sister, one of the Garuda's Wizards, though she occasionally works as the Wizard for Chris after Arque's death. In the battle of the Shanghai server, she was salvaged to the Oceanus. The bespectacled sister, Kyo refers to her as the cute one, much to May-Yu's chagrin. Like May-Yu, May-Yen is devoted to Lu-Shen. She and her sister are from Shanghai.
