Ayukawa is a university student who thinks that books are everything to him, books are the intelligence of mankind itself, so that human nature is the opposite of books, making him hate humans... but, even though he claims that he hates humans, there is someone he likes, it was a librarian he met at the library, because of that passion, he ended up going to the library often. However, even though she often went to the library, their relationship was not progressing at all, so she wondered if there was a book that could help her..., and she also found a book about rituals... long story short, she did the rituals in the book, it was said that if you wish for the person you dreamed of during the ritual, that person will appear in front of you, but instead of expecting the librarian, she wishes for someone who can give her love advice. That someone appeared, but he wasn't human but a tsukumogami that came from the flipped books on his bookshelf...
