User:Kaido King of the Beasts/Monty's Devil Fruit

The  no Mi is a Paramecia-type Devil Fruit that allows the user to manipulate books and put targets inside them. It was eaten by Charlotte Mont-d'Or.

Strengths and Weaknesses
The user has full control over books, allowing them to remotely, telepathically move and open, even levitate, and otherwise manipulate them; Mont-d'Or has enough control of them to efficiently use them as mid-air footholds.

The biggest strength of this fruit is the ability to put both living or non-living targets inside a book's setting, which Mont-d'Or calls the World of Books ("本"の世界). This can be done in two ways: in the first one, by hovering an open book over the target, the target will be placed under the (at least visual) illusion that they are in the book's world; their body will still be in the real world, and the user can take advantage of the target's inability to see the same by attacking them then; the illusion will cease once the book is shut again. Secondly, the user can also place a target directly in a book itself, preferrably one that already is a picture book, in which the target will become an illustration in that book; while inside the book, they will not age (something likened to how any book's content does not simply change whenever the book is opened), and the user can use other in-book illustrations to affect the trapped targets, such as Mont-d'Or pinning down his captives with oversized nail-like appendages.

If a target is placed under the illusion of a book's setting, they still have access to their abilities and some senses other than sight, and can still move around in the real world, as shown when Monkey D. Luffy was able to hear Nami while under the illusion and could move. Also, those truly trapped inside a book are able to communicate with the real world so long as their page is open. Otherwise, the user is affected by the standard Devil Fruit weaknesses.

Usage
Mont-d'Or's most prominent use of the fruit's power lies in his trapping of many strange creatures as well as prisoners inside oversized picture books with appropriately empty picture frames (but the pictures of prisoners marked by prison bars), pinning them down with massive nails and keeping them in a large Library in Whole Cake Chateau. The Library's normal section is for Big Mom's collection of strange, rare creatures and beasts while normal prisoners have their seperate section called Prisoner Library.

In combat, Mont-d'Or may control normal-sized books to give him footholds and also place foes under illusions with them, allowing his allies the opportunity to attack the sitting duck opponent.
