My Instant Death Ability is So Overpowered, No One in This Other World Stands a Chance Against Me!

Yogiri Takatou finds himself awoken in the middle of chaos during a school trip, only to discover his classmates have been transported to another world while he slept through the event. The others received the Gift, special powers bestowed by a mysterious Sage, which Yogiri somehow missed out on. He's left to protect his one remaining classmate, who was abandoned as bait to distract a nearby dragon. Yogiri possesses a unique ability: he can instantaneously kill creatures with a single thought, a power that should make him a formidable force against the Level 1000 dragon.
