Once upon a time, there was a tribe that fought for the empire. They were feared by everyone. Their specialty was destruction and slaughter. They were called "kimera." Rin was one of them. She lived in a peaceful village until the war broke out. And at that moment, something within her began to awaken, and something beyond imagination began!

Kimera is about a malevolent demon who takes on the bodies of the people where he is implanted (human hosts). When the demon is implanted in a body of a baby, a soldier is sent to kill the child, but the soldier did not have the heart to kill the baby and leaves it to lives. 17 years pass in the history of the child has grown up.
