The white cat who swore revenge indulges in lazy sleep on the dragon king's lap [Novelization & Manga Adaptation]

On her way to university, Ruri is suddenly summoned to another world along with her middle school classmates when the ground begins to glow. It seems she was caught up in a summoning ritual—those performing it intended to call forth a shrine maiden princess who would bring prosperity to the nation. At first relieved that her food, clothing, and shelter were guaranteed, it wasn't long before one of her classmates' conspiracy resulted in her being abandoned in the forest as a criminal. Chased by mysterious monsters, Ruri—who had sworn revenge against her classmates—was rescued by a witch living quietly in the forest. Learning magic under the witch's tutelage, Ruri steadily gained the power needed for her revenge, and then... For some reason, she had become a white cat and was contentedly napping on the lap of the Dragon King. The work has been novelized by Arian Rose. Additionally, a comic adaptation is currently being serialized on Comic Walker.
