The Cat Who Saved Books

Rintaro Natsuki is a shy, bookish high-school boy who has just lost his beloved grandfather, the owner of a small, cluttered secondhand bookshop called Natsuki Books. Withdrawn and unsure how to face the world, Rintaro shuts himself away among the shelves — until a talking tabby cat named Tiger strides in and demands his help.

Together, boy and cat set out through a series of strange, labyrinthine quests to rescue books from people who have imprisoned, neglected, or betrayed them: a man who hoards volumes he'll never read, a scholar who chops books into digestible summaries, a publisher who cares only for profit. With each journey, Rintaro learns something about courage, empathy, and why stories matter.

Sōsuke Natsukawa's gentle, whimsical fable is a love letter to books and the readers who cherish them.
