A brief description of the My Instant Death Ability is So Overpowered, No One in This Other World Stands a Chance Against manga:
Cheating skills? Endless magical energy? The ability to destroy an entire species? What’s the point if instant death comes after a single attack?
High school student Yogiri Takatou was on a tour when he woke up because a dragon attacked their bus. The only survivors were him and his screaming classmate Tomochika Dannoura. It turned out that the other classmates had received superpowers from Zion, a woman who introduced herself as “The Sage,” and ran away from the dragon, leaving those who had not received any powers to tear the monster apart.
And so the misunderstood Yogiri was sent to a parallel world full of dangers. Still, Zion has no idea who she called!
