On her way to university, Ruri was suddenly summoned to another world with her junior high classmates when the ground unexpectedly glowed.

The summoners had intended to call forth a shrine maiden princess to bring prosperity to their nation, but Ruri was merely an unwitting participant.

Fortunately, her food, clothing, and shelter were guaranteed, but her relief was short-lived when, due to the machinations of one of her classmates, she was abandoned in the forest as a criminal.

Pursued by mysterious monsters, Ruri, who had sworn revenge on her classmates, was picked up by a witch living quietly in the forest.

Learning magic under the witch's tutelage, Ruri steadily gained power for her revenge. Afterwards…………
