Sokushi Cheat ga Saikyou sugite, Isekai no Yatsura ga Marude Aite ni Naranai n desu ga.

Yogiri Takatou wakes on a school trip bus to discover that his entire class has been transported to another world and most of his classmates were given special powers by a mysterious Sage. Because he slept through the event, Yogiri received nothing, and soon learns that the others abandoned him and Tomochika Dannoura as bait for an approaching dragon.

What no one knows is that Yogiri does not need a “Gift” from this world. He can kill anything simply by deciding it should die, regardless of strength, immortality, or magical protection. He tries to find a way home with Tomochika while causing as little trouble as possible, but a world filled with arrogant heroes, monsters, and beings who consider themselves gods keeps challenging the one person it absolutely should not.
