It’s the birth of the strongest protagonist who can kill all his enemies instantly!

During a school trip, Yogiri Takatou and his classmates were suddenly summoned to another world. The one who summoned them is a Sage named Sion. She gives them a special ability called “Gift”, and unilaterally pronounces that they must complete the trials to become a Sage.

Even though they are all still shaken by the sudden situation, they begin to take action.

However, for some reason, some students cannot receive Gift, including Yogiri and Tomochika Dannoura. Those students without abilities are left as decoys when a dragon is approaching.

The remaining students are killed one after another by the dragon. yogiri and Tomochika are in danger!

…that was what we thought.

“Die.”

Yogiri defeated the dragon with a single word. And what a surprise, he has an “Instant Death” ability, which allows him to instantly kill any target of his choice!

Yogiri and Tomochika begin a journey in order to get back to their original world. They meet various people from another world who have cheat-like abilities. An immortal vampire? A redo of a hero? A reincarnated person who is doted on by the gods? They are not a match against the Instant Death ability!

An adventure in another world of a downer boy with an unprecedented cheat ability as his weapon and a slightly clumsy pretty girl now begins!
