After being summoned to another world, Yogiri and Tomochika were abandoned by their classmates as bait to distract a rampaging dragon. Thanks to Yogiri's ability to cause instant death with a single thought, the two of them survived and made the arduous journey to reunite with their classmates in the capital city. Although they overcame tremendous danger along the way, rejoining the other students is still only the beginning. From the intricate schemes of the Sages Yogiri inadvertently made into his enemies, to being stalked by Ayaka Shinozaki, a synthetic classmate who acquired the power of a dragon and swore to take revenge on them all, to the machinations of Lute, the spawn of a monster Yogiri slew, who is now bent on releasing yet another Dark God imprisoned beneath the city, there is no shortage of people determined to kill them. Somehow, the unlikely duo must juggle these threats while attempting to draw out the Sage Sion in hopes of discovering how to make it back home.
