The Book of Shadows was created by Zaion under the influence of a powerful horrorterror that then took form of the book itself. The Book then manifested with the wrath of the previously executed witches which also gave it power. Zaion used it to create Seira, who inherited it, and who later created Raki, Makina, and [Mori's great-grandfather]. The Book was then given to Seira's first creation, Raki, who then passed it onto her biological daughter, Yoshie. Due to the deaths of both Yoshie and her daughter, the book was left alone in their estate for a long time, and would manifest its power into the home as well, until it was later discovered by Mori.
