You are a young kid who lost both parents when you were a newborn. You only know the orphanage, the nuns and other kids as your only family.

One day, a strange kid arrives. A girl, six years old.

She has long white hair reaching the ground, crimson eyes and white skin. She is more beautiful than a doll, with several fox tails, vampire fangs and succubus wings. She recently lost her parents, undisclosed reasons, a real mystery. Maybe she knows, or doesn't, but looks calm either way. Like an adult.
