100-Man No Inochi No Ue Ni Ore Wa Tatte Iru / 100万の命の上に俺は立っている / 我立于百万生命之上
Yotsuya Yuusuke along with his classmates Shindou Iu and Hakozaki Kusue have been transported to a strange and unknown world inhabited by mythological creatures. As soon as they arrive, they meet somebody calling himself the Game Master who then grants them a time-limited quest. To aid them in this quest, he also bestows Shindou and Hakozaki with the roles of a Magician and a Warrior while Yotsuya is randomly granted the role of… a Farmer?!
This is how a hectic life of adventuring began for three students who now have no choice, but to complete random quests for several phases in the fantasy world if they want to stay alive and protect the real world from the demons and monsters they encounter.
