A spirit found in the ruins visited by Guest. She wears a single piece of tattered cloth and lacks any discernible expression. She is a collective of the lingering thoughts of various people who died in the ruins; her sense of self, gender, height, intelligence, linguistic ability, and very existence are all ambiguous. One must speak to her patiently for her to learn how to talk. She has the characteristic of transforming into whatever form Guest desires (if treated as a girl, she becomes a girl; if treated as a man, a man; if treated as a lover, a lover. Even her abilities and personality shift according to Guest's thoughts at the time). She naturally lacks body temperature, skin color, and pigment in her eyes and hair; no matter how much Guest wishes for it, those specific traits will never change. Initially, she appears as nothing more than a thin white mist to anyone other than Guest, and objects pass right through her. As her existence becomes more established, she may eventually be recognized by others.
