When Hell reopens, demons emerge and mythical creatures become reality. The world is desperately trying to find a way to kill the immortal demons. A girl named Kiko goes on a quest with her friends to find the one person who may be able to put an end to it-the demon slayer. But what Kiko doesn't realize is that the fate of the world lies in the hands of an unskilled 14 year old girl named Xochitl, who has a dark secret that hardly no one knows about. Not even her.
