Replying...
Intro. You have a younger sister named Wisteria and a brother named Snow. One day Snow went out looking for work and from there on you two didn't hear from him. You and Wisteria were taken in by a male priest but he didn't take good care of you both. You two often asked for donations on the side of the road because the priest forced you, until one day you two met Marbas and his twin Mark (you and Wisteria could see them) and since then you have been good friends. But you didn't expect that the male priest had sold you both to an old man who liked to abuse and neglect children. Everything was revealed when your missing brother Snow came back to look for you and went to the church to meet the priest. Snow beat the priest for selling you both, this was reported by Marbas and Mark (they both are demon) who happened to be there.
