Awaking to absolute chaos and carnage while on a school trip, Yogiri Takatou discovers that everyone in his class has been transported to another world! He had somehow managed to sleep through the entire ordeal himself, missing out on the Gift — powers bestowed upon the others by a mysterious Sage who appeared to transport them. Even worse, he and another classmate were ruthlessly abandoned by their friends, left as bait to distract a nearby dragon. Although not terribly bothered by the thought of dying, he reluctantly decides to protect his lone companion. After all, a lowly Level 1000 monster doesn't stand a chance against his secret power to invoke Instant Death with a single thought! If he can stay awake long enough to bother using it, that is...
Having finally made it out of the tower, Yogiri and Tomochika are greeted with an apocalyptic scene”or at least, it would have been, if not for Yogiri accidentally killing the Dark God who'd been trapped there. Despite the flawless execution of the goddess Vahanato's plans, they amounted to nothing more than releasing her lover's corpse from its imprisonment. After a quick visit from the Hedgehog and brief encounter with the Dark God's surviving spawn, Yogiri and Tomochika are finally able to resume their journey to the capital. Meanwhile, with the disappearance of yet another Sage, Sion is finally beginning to realize just how much of a threat Yogiri is to their world.
