100-man no Inochi no Ue ni Ore wa Tatte Iru

Yusuke Yotsuya, a distant middle school student gifted with a keen sense of logic, is transported into an alternate world that resembles a game. With his female classmates Iu Shindo and Kusue Hakozaki, he thus becomes the third player to undertake a quest riddled with dangers. Due to his unemotional nature, Yusuke manages to face the most difficult situations thanks to his detachment, even sometimes playing with the lives of his companions.
