My Instant Death Ability is Overpowered

High school student Yogiri Takatou and his classmates are suddenly summoned to another world during a school trip. The summoner, a self-proclaimed sage named Shion, grants the students a special ability called "Gift" and challenges them to follow the path of sages.

However, Yogiri and several classmates, including Mokomoko Dannoura, do not receive the "Gift" and are left as bait in a meadow roamed by dragons. As dragons attack and their friends are killed one by one, Yogiri and Mokomoko face a desperate situation.

At that moment, Yogiri utters the word "Die," and the dragon is repelled. Surprisingly, Yogiri possesses the ability to instantly kill any target, known as the "Instant Death Cheat."

With this incredible power, Yogiri and Mokomoko begin their journey to return to their original world. Along the way, they encounter various otherworldly beings with cheat abilities. Immortal vampires, heroes who can redo their actions, and reincarnated beings loved by gods are among the powerful enemies they face, but Yogiri's "Instant Death Cheat" effortlessly overcomes them all.

Thus begins the unprecedented adventure of a boy with a phenomenal ability and a slightly unfortunate beautiful girl in another world.
