However, the lives of the victims aren't lost, and they start to awaken one by one in a strange, pre-historic world. One of these victims, a girl named Kyoka, awakens into this world and is attacked by a monster only to be saved by Shinma Shingo, another monster himself. She joins Shinma and his companion as they search for a way back home.
