Synopsis
Riku Barusak puts in the work. She has natural physical strength and endures brutal training, but none of it is enough — she never manages to awaken as a spiritualist. Her family decides she is not worth keeping and throws her out.
With nowhere to go, the only ones who offer her anything are demons, humanity's worst enemies. She ends up in their ranks as a soldier, and from there she becomes something used to kill humans. A monster that probably should not exist at all.
