Shiro Shiro no Mi

Unreleased

The Shiro Shiro no Mi is a Paramecia-type Devil Fruit that allows the user to become a living fortress. "Shiro" (城) is a Japanese term for "castle". It was eaten by Capone Bege.

Strengths and Weaknesses
The main strength of this fruit is that it allows the user to becoming a living fortress, the inside of their body holding many cannon ports and drawbridges, and stone brick rooms. The user can hold even living people inside their body, by shrinking their sizes as long as they are within a vicinity within the user. When the objects and people within the user reach a certain distance away from the body, shown by a pinkish layer of an unknown aura centered on the user's location, they revert to full size.

Should the user be inhaling smoke or any similar substances, the insides would be filled with it as well, as when Capone was smoking a cigar, the soldiers inside were suffering from cigar smokes. Other than that, the user is also weak to the standard Devil Fruit weaknesses.

Usage
You guys have already lost... in sheer military force. Capone Bege primarily uses his ability to launch a powerful surprise attack against unsuspecting adversaries. Holding his entire crew within his own body, they can launch cannon blasts from his body, which would return to full size once leaving the boundary of Bege's ability. The troops can also rush outside of their captain's body via horses to overrun the enemies. All of this results in large cannon volleys and cavalry seemingly popping out of nowhere from one man.
