There have been some strange disappearances in and around Tatsumi Town, so a group of students decide to launch an investigation in hopes of figuring out what happened. They soon discover a book entitled End Earth, which they believe may have something to do with the disappearances, though they’re soon met by a strange creature who inadvertently takes them to another world. Now, Souma and Kureha must do what they can to get back to their world, though in this strange new world, they’re not sure how exactly they’re supposed to do that.
