In the spring of his second year of high school, protagonist Shizuma is arbitrarily placed by his teacher into a school trip group with high-ranking classmates he has no prior association with.

Suddenly, their group, along with the microbus they were traveling in, is summoned to an unknown world.

Through the power of a mysterious entity wielding strange powers, 'The Dungeon Master,' the entire group obtains the right to have any wish granted, albeit with conditions. However, Shizuma is left behind due to the machinations of one student――

As a result of his granted wish, Shizuma obtains power far exceeding expectations. He kills the Dungeon Master and, to decide how to wield that power himself, breaks ties with the summoners and his former classmates.

「I don't actively seek revenge, but I probably won't help them, I guess.」

How will Shizuma, who possesses all types of characters—'Combat Jobs,' 'Production Jobs,' and 'Joke Classes'—operate?
