Shindou Yuu, Hakozaki Kusue and Yotsuya Yuusuke suddenly find themselves in another world as an adventuring party with zero combat experience and must defeat a powerful troll.

Shindou and Hakozaki are unable to revive themselves after being eaten by a troll; in the midst of fighting alone to raise his level, Yotsuya is upgraded to a new job class, Chef. He uses his new job skills to save the two girls.

The party heads toward Radodorbo, a village far to the west, to complete the latest stage of their quest; however, bandits capture Shindou on the way; Tokitate and Hakozaki want to save her, but Yotsuya just wants to hurry on.

Yotsuya's party saves the people who were under attack by kobolds; they find out the group is a squad of soldiers from the dictatorial Kingdom of Deokk and they're escorting heretics to Radodorbo to be executed.
