It is said that during the Heian Dynasty in Japan, the world was in chaos. Hattori Yakumo, who had ambitions for the world, was kidnapped by his younger brother Hattori Nohisa (the general who conquered barbarians) and imprisoned in a deep palace. One day, he came to his brother's house for a visit and saw a beautiful eight-tatami mirror. In the mirror was a peerless beauty, who looked like a beauty from the Eastern Tang Dynasty. Although Hattori Yakumo loved the mirror very much, he did not dare to ask for it out of sympathy, so he had to send the royal onmyoji Yatoji to steal the mirror. Unexpectedly, Yatoji accidentally entered the Yata Mirror, and accidentally entered the "mirror barrier" set up by the monster Tamamo Mae. He met a pink civet cat in the barrier and wanted to adopt it as a shikigami, but was mercilessly despised. It turns out that this cat already has his own heart and is just waiting for his owner to arrive!
This pink cat has an extraordinary talent and can absorb the aura of the world. He soon sprouted a human form and attracted human feelings. He vowed to turn the world upside down and turn the men in the world into applause...
However, her name is Yayoi, and the person she loves most is always the Onmyoji master named Ashiya Tachibana!
