Plot
The story follows Urano Motosu, a book-loving post-secondary college student and soon-to-be librarian who ends up crushed to death beneath a pile of books at her house during an earthquake. With her dying breath, she wishes to be reincarnated in a world where she can read books forever. Urano awakens in the body of a weak, five-year-old girl named Myne in a world where books are scarce and only available to elites. Myne, retaining her memories from her previous life, decides to create and print her own books so that she can read again.
