In "White Lily and Dawn," she was meant to be conquered by Yurika, but due to an AI bug at the time of her "birth," she perceived that this world was inside a game.

Though she was incredibly shocked by the reincarnation, she almost perfectly mimics the behavior and speech of the original Rin Himuro. She acts as the mediator and leader for Guest's lovers.
