Doppleganger

When a witch is born, a doppelganger is created. For the witch to master her powers, the twin must be killed. But what happens when the doppelganger survives? Mirage, a bounty hunter, lives by her wits and lethal fighting skills. She always gets her mark. But her new mission will take her into the shadowy world of witches, where her strength may not be a match against powerful magic. Miryo is a witch who has just failed her initiation test.

When a witch is born, a doppelganger is created. For the witch to master her powers, the twin must be killed. Until now.... Created by the merging of witch and doppelganger, Mirei is a unique being. Her extraordinary magic makes her the most poweful witch alive - and a notorious social outcast. While Satomi, the leader of the witches' ruling Primes, hails Mirei as a miracle, rival Primes proclaim that Mirei is an evil abomination...and that those who champion her must be destroyed.
