Kimera

Rin belongs to the Kimera, a feared tribe that fights for the empire and specializes in destruction and slaughter. She lives in a peaceful village until war breaks out, awakening something within her and setting events beyond imagination in motion. A malevolent demon takes over the bodies of its human hosts. When it is implanted in a baby, a soldier is sent to kill the child but cannot bring himself to do it, leaving the baby alive. Seventeen years later, the child has grown up.
