My Instant Death Ability Is So Overpowered, No One in This Other World Stands a Chance Against Me! -AO-, Vol. 2 (manga) — Tsuyoshi Fujitaka

Transported to another world and abandoned by their friends as bait for a nearby dragon, Yogiri Takatou and Tomochika Dannoura manage to survive thanks to Yogiri’s power to invoke Instant Death at will. Despite having been abandoned by them, the pair decide that their best option for making it in this world is to reunite with their classmates, and they set off after them. After a few close encounters in the city of Quenza and on the train taking them onwards, the two manage to reach the city of Hanabusa, a place that seems to mirror modern Japan. They decide to wait there for the rest of their class to catch up but come across a rogue classmate who has already reached level 10,000 and seems dangerously close to world domination!
