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.

Yotsuya sneaks into the girls' restroom of an unfamiliar high school and saves Tokitate Yuka from being bullied by her classmates; Tokitate turns out to be the fourth party member.

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 succeeds in saving the other party members with Kahvel's help; Kahvel agrees to accompany them to Radodorbo if they'll allow her to train them in swordsmanship.

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.
