My Instant Death Ability Is So Overpowered, No One in This Other World Stands a Chance Against Me! -AO-, Vol. 7 (manga) — Tsuyoshi Fujitaka

With the events of the tower behind them, Yogiri and Tomochika begin making their way through the Meld Plains, a foggy expanse of crystalline plants and animals, towards the capital, in hopes of reuniting with the classmates who left them for dead on the bus. After dealing with a short distraction on the plains, they manage to make it to the city but find that getting permission to enter may be a bit more complicated than they had first hoped. Meanwhile, another member of the class who had been abandoned wakes up in the ruins of their tour bus. Disoriented and critically wounded, she finds she is not quite as alone as she thought, and Yogiri left behind just the thing she needs to treat her wounds.
