Shindou Yuu is an amateur model at the top of her class, and Hakozaki Kusue is a physically weak girl who misses school a lot. One moment, Yotsuya Yuusuke is thinking that the sight of these two together seems unusual... and the next, he finds himself in another world. Suddenly Hakozaki, a warrior who can't even swing a sword, and Yotsuya, whose only weapons are a hoe and a sickle, are a party with zero combat experience stuck with the task of defeating a powerful troll.

After being told by the Game Master to hit on a certain girl, 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. When she's summoned into the other world, Tokitate develops a deep admiration for Shindou, whom she sees as much stronger and prettier than herself.... but Shindou also has a past that she can't tell anyone about.
