There are only two ranks, Master and Slave. Obviously in this mansion, the white hair and pale skin people are always the masters, and brown hair and tan skin people are slaves. It's always has been like that by generation ages ago. Slaves always have to give their bodies to their masters. And they also forced to make another slaves by giving birth. For a Slave, this mansion is such a hell.
