==Abilities==
The woman is shown to be present throughout Chaldea without anyone noticing her. She also completely froze and then shattered the Russian Lostbelt's Fantasy Tree with but a single touch.
The instruments of the Shadow Border are unable to detect her presence, instead detecting simply [nothingness] where she stands. Holmes describes her as a void-like emptiness seeping out into the space around it. She can somehow make her existence perceivable only for certain people, proven when, even in the same room, Sigurd in his spiritual form was unable to sense her presence nor see her, falsely believing his master was talking alone.
