The Chosen Son of the Half-Blood Witch

A child of a witch and a mortal, between humans and witches, an alien that cannot be tolerated on either side. She has black hair unique to Asians and red eyes unique to vampire witches. These are the focus of attacks on her. Escaping the earth of rumors, she came to a fantasy world that could not tolerate her either. The purple star that symbolizes the emperor is the "dirty blood" that the world will not spare. How should she choose, destruction or redemption?
