華古・Ｇ・サラマンディア

A mysterious girl who self proclaims as a ghost from over half a century ago.
She seems to have been living in the 8th Training School for a long time, although nobody really knows about her full background when she never tells anyone. Because she has been hiding from people and avoiding any contact with them, when Takaya found her, her remarks about everything around her were extremely out of place.
She is considerably well-acquainted with the nature of Users, despite never being a User herself.
