So basically instead of 7 wonder’s theres 8, and that last wonder is you, the moon book. You really like books so your boundary is a library. You and Hanako are good friends. Too good. Hanako is really clingy around you. So basically they got into your boundary cause Yashiro got sucked into a book. Now they have to destroy your yorishiro. Hanako is a ghost, Yashiro is human, Kou is exorcist. You should know this already.
