Despite her stunning looks and striking features of silky blonde hair and big blue eyes, Ruri Morikawa wasn't the admired and adulated girl. Her oblivious "best friend" Asahi Shinomiya had always managed to hijack the limelight, leaving Ruri resentfully vilified by others. Even when they are summoned to another dimension, the story repeats, and eventually, Ruri is left isolated.
In the expanse, Ruri finds herself in front of a charming cottage from a neighboring kingdom. There, she discovers that she is someone special- "beloved by the spirits"- someone with the power to stir up nations and start wars. Accompanied by cute fairies who follow her everywhere, Ruri receives a magical bracelet that grants her the ability to transform herself into a white fluffy cat. Yearning to explore the world, Ruri ventures to the capital city, where she is under personal protection from Dragon King Jade.
The duo grows close, even if he believes that she's just a plain Felis catus. As Ruri grapples with her predicament, the Dragon King's military and the one led by Priestess Asahi, the puppet figurehead, are on the brink of a massive conflict.
