Ash is the phantom of a young man who protects Marona. When he was alive he worked alongside Marona's parents as a Chroma. After dying along with them, he found himself stuck between life and death, thanks to the efforts of Marona's father. He has since sworn to watch over and protect Marona, feeling that he owes Marona's parents for being the only one to "survive" their unfortunate demise. He is usually careful and well-intentioned, if overprotective of Marona, but is sometimes known to frighten the unwary when he accidentally speaks aloud while concealed in his phantom form. He frequently objects to Marona's selfless behavior.
