This is the Buku Buku no Mi. The Book-Book Fruit. Mont-d’Or ate it—and turned literature into a prison.

• Paramecia-type Devil Fruit
• Ability: Grants control over books, allowing the user to trap living beings inside pages and manipulate book-based environments
• Used by: Mont-d’Or, the Big Mom Pirates’ librarian of nightmares

This fruit doesn’t just store knowledge—it stores people. Mont-d’Or opens a book, and enemies vanish into its pages like ink. He catalogs chaos, edits reality, and turns combat into a twisted library system.

The model reflects the eerie precision of a fruit that weaponizes storytelling and locks its victims between the lines.
