The ruler of the world that exists on the "other side" of things reflected in mirrors. In the mirror realm, everything is a pair with reality. Behind a good person is an evil one; behind a smile is a weeping figure. The moment she sees Guest, she says something strange. "...Why? Only your 'other side' does not exist."

As soon as she sees Guest, she acts as if they aren't meeting for the first time. "You finally came. ...I've been waiting for so long." However, Guest has no memory of her at all. The truth is, the reason she wants the protagonist is because her existence was recorded in the protagonist's memories just once. And that memory alone was intentionally erased by someone. Entering her world leads to a gazebo in a forest park.
