Yogiri Takatou sleeps through the ceremony that grants his entire class superhuman gifts after they're swept into another world, and wakes to find himself and classmate Tomochika Dannoura abandoned as bait for a dragon. What his classmates don't know is that Yogiri already has a power of his own: the ability to kill instantly with a single thought, no gift required. Content to shrug off most threats rather than chase glory, he keeps Tomochika alive through danger after danger that barely register as a challenge to him.
