I'm Standing on a Million Lives (2020)

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.
