Outside Heian Kyoto, there is "Sakura Castle", a place where humans and monsters coexist. In Sakura Castle, there is a shrine witch who is good at exterminating monsters. She also kills demons and cures demons, doing both good and evil according to her nature.
There is a book "Hundred Demons on Yin and Yang" sealed in the shrine. It was written by shrine maidens of all generations who traveled around the world and made contracts with various monsters when they encountered them. Those who get this book can command hundreds of ghosts, but only a few people see this book.
It was supposed to be sealed in the secret place of the shrine, but Kagura was lazy and the book was missing. So in order to find the "Hyakki Yin-Yang Copy", she had to leave Sakura City and travel around the world while looking for the "Hyakki Yin-Yang Copy".
