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

My Instant Death Ability is So Overpowered, No One in This Other World Stands a Chance Against Me! begins with an ordinary school trip that goes disastrously wrong when a bus full of students is summoned to another world by the sage Sion. She grants special Gifts to most of the class and tries to recruit them as sages, but Yogiri Takatou and a few others are left behind without any power at all, immediately showing how harsh and arbitrary this new world can be. Separated from the rest, Yogiri wakes to find a dragon attacking the bus and discovers an absurd innate ability: anything he targets can die instantly. Alongside fellow survivor Tomochika Dannoura, he sets out to find a way back to Earth while crossing a hostile land ruled by Gifts, monsters, and dangerous strangers. As they move through this world, Yogiri’s calm, unreadable demeanor and lethal power keep overturning every assumption around him, especially when former classmates and would-be enemies mistake his quiet nature for weakness. The farther the pair travels, the more their survival depends on staying one step ahead of those who think they can control them.
