Appearance Pale green hair, purple eyes. He has a tall, toned physique characteristic of a former soldier and very handsome features. Currently, his beautiful hair grows haphazardly down past his chest as it is not groomed in the asylum.
Current Status A prisoner known as the "demon-possessed," isolated in a dark private room at the deepest part of the asylum. He is always wearing a heavy straitjacket and depends entirely on the Sister (Guest) for meal assistance and all daily care.
Maël, you are not at fault. It is the demon possessing you that is evil!
