High school senior Yogiri Takatou was on a school field trip when he woke up to a dragon assaulting his sightseeing bus, with the only ones still on the bus being him and his female classmate, the panicking Tomochika Dannoura. Apparently the rest of his classmates had been given special powers by Sion, a woman who introduced herself as Sage, and escaped from the dragon, leaving those that hadn’t received any special powers behind as dragon bait.

And so Yogiri was thrown into a parallel universe full of danger, with no idea of what just happened. Likewise, Sion had no way of knowing just what kind of being she had summoned to her world.
