100-man no Inochi no Ue ni Ore wa Tatteiru

Yuusuke Yotsuya dislikes city life and prefers games to dealing with people, so he is stunned when he is suddenly transported into a fantasy-like world with classmates Iu Shindou and Kusue Hakozaki. A mysterious Game Master gives them timed quests and random classes, but Yuusuke's role seems almost useless compared with what he expected. Death is temporary as long as one party member remains alive, yet the pain is real and every new quest becomes harsher. What initially resembles a game turns into a moral problem when Yuusuke begins to suspect that their decisions affect a world populated by people whose lives do not reset so easily.
