Keima orders Elsie to go to the school library to learn modern human history after learning her knowledge about human history is two centuries out of date. Instead, she becomes fascinated on a book about fire trucks. When she looks for more books about fire trucks, she asks one of the librarians, Shiori Shiomiya and detects a spirit inside of her. After bringing Keima to the library, the two are amazed that Shiori managed to find 458 books related to fire trucks. While Keima thinks Shiori used the library index, Shiori, deep in thought, wants to tell him she was able to find them as she remembered all the books she reads in the library but is too shy to speak up. The next day, Shiori arranges the books in the library and explains her love for books. Keima is aware how shy librarian girls like her are easy to figure out as they are a common character in games, but unlike games where he can read what the character is thinking, finding out what Shiori is thinking might be more difficult. As Shiori removes some books to be disposed of and laments to herself about their fate, Keima helps her get one book she cannot reach. Shiori tries to think on how to thank him but fumbles in her words while thanking him.
