The Shiro Shiro no Mi[2] is a Paramecia-type Devil Fruit that allows the user to become a living fortress, making the user a Castle Human (城人間 Shiro Ningen?). It was eaten by Capone Bege.[1] Its powers were first revealed in the Sabaody Archipelago Arc, but the name of the fruit was not given until the Zou Arc.


  • "Shiro" (?) is a Japanese term for "castle".
  • In the Viz manga and Funimation subs, it is called the Castle-Castle Fruit.

Strengths and WeaknessesEdit


Shiro Shiro no Mi's Size Manipulation

The fruit manipulating size around the user.

The main strength of this fruit is that it allows the user to become a living fortress, the inside of their body holding many openings, including cannon ports, portcullis and drawbridges; deeper inside contains various rooms, ranging from stone brick rooms for combat to well-refurbished meeting halls, complete with long-table, chairs and even decorations. The user can hold even living people inside their body, by shrinking their sizes as long as they are within the vicinity of the user. When the objects and people within the user get out they return to their normal size. This can be done by exiting a certain distance away from the body, shown by a pinkish layer of an unknown aura centered on the user's location, or through a unique alternative route like when the Sanji Retrieval Team left through the Mirro-World.[3] When the user grows to unleash the fortress' full size, the shrinking affect is nulled. In addition, the user's castle defenses can be deployed in a circular formation to give them a full 360 degrees of protection and attack coverage, as well as the potential to conduct decisive surprise ambushes.[1][2]

Bege's Banquet Hall

The banquet hall within the body fortress.

As long as the user does not manifest castle features on their external body, the castle features of their internal body will remain concealed and unnoticeable. This has the advantage of lulling others into a false sense of security who think they are facing a single individual in combat who appears to be lacking armaments on the surface, only for the fruit's user to reveal the militia and weaponry hidden within. If the user does not wish to engage in combat personally, they can shield themselves by releasing their subordinates and let them do the fighting for them. The user can also use their body as a storage facility for recreational purposes, as they are shown to house food and drink for subordinates and any outsiders.[2] The user has complete control over the fortress in their body, and can telekinetically move around and create objects from inside as they see fit. However, movement from the outside does not seem to affect the inside, as the Straw Hat Pirates did not feel any movement vibrations when Bege started walking back to the ship.[4]

Capone Bege Inside Himself

Bege creates a miniature version of himself inside the fortress.

The user also seems to have the ability to make a miniature version of themselves through a strange fluid as a way to communicate with those inside, however, being in their own body, the user can still just talk in order to be heard.[2] They are capable of being alert and moving around in the real world while also being in their own body.[4] Should any damage occur to the outside body, the miniature version will reflect said damage on itself, feeling pain and showing visible injuries on their equivalent spot of the damaged area.[5]

Additionally, the user can also turn their body into an actual fortress, resembling a humanoid golem; while they still retain a humanoid form, they will grow significantly in size as their skin becomes stone and the rooms in the castle become life-sized.[6] The fortress has immense defensive power, being immune to cannonfire and even withstand a ruthless beating from the Yonko Big Mom (at least for a while), making it a suitable safe haven in the midst of a battlefield.[5] The user is able to turn their body into parts of a fortress, as shown when Bege turned his legs into tank treads.[4]


So, far this Devil Fruit has displayed no direct offensive abilities that affect those outside the user. This Devil Fruit's full potential seems to be dependent on the presence of other people within the user's fortress body in order to use weapons and launch ambushes against threats located outside the fortress.[1]

Should the user be inhaling smoke or any similar substances, the insides would be filled with it as well, as when Bege was smoking a cigar, the soldiers inside were suffering from secondhand smoke.[1] Anyone can escape his body should they simply exit through an opening, so the user must monitor prisoners at all times or keep the doors closed.[4]

The insides of the fortress can also take structural damage such as by catching on fire, although it is unknown how this affects his body.[4] On the outside, when in full fortress form, the castle is a sturdy defense, but not impregnable. Since the fortress is the user's actual body, any damage inflicted onto the walls is effectively injuring the user. Should the giant castle be destroyed, it will disappear and the user will die, and anyone taking refuge within will be expelled into the open. The artillery of the giant fortress seems to have limited ammunition, and they can be clogged by foreign objects, causing them backfire. Also, the mobile strength of the fortress can be restrained by sufficient strength, such as specialized candy.[5]

Other than that, the user is affected by the standard Devil Fruit weaknesses.


You guys have already lost... in sheer military force.

Capone Bege's Ability

Bege launching a heavy ambush attack with his ability.

Capone Bege primarily uses his ability to launch powerful surprise attacks against unsuspecting adversaries. Holding his entire crew within his own body, they can fire guns or 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 and surround their enemies. All of this results in bullets, large cannon volleys and cavalry seemingly popping out of nowhere from one man.[1]

Bege Controls Banquet Hall

Bege controlling the inside of his fortress, creating traps and weapons.

Bege also uses this ability to provide a place for him to have private conversations with other people.[2] When he does this, he is able to appear from a liquid form. When his larger body isn't moving, it remains dormant, and his eyes glaze over, however, his body is still capable of walking when he chooses to do so. Having his targets inside his castle grants him a field advantage, allowing him to overwhelm his opponents by forming weapons and traps anywhere he desires.[4]


Castle Tank

Castle Tank.

  • Castle Tank (キャッスルタンク Kyassuru Tanku?): Bege manifests tank treads around his leg area, allowing him to move at high speed, similar to Franky's technique. It is unknown if his legs are covered by the treads or transformed into them; the anime shows the latter. This was first used to escape Nekomamushi after capturing Sanji and Caesar Clown in his body.[4]
Big Father

Big Father.

  • Rook In Voller Größe: Big Father (城 (ルーク) イン・フォラ・グレーセ 大頭目 (ビッグ・ファーザー) Rūku In Fora Gurēse: Biggu Fāzā?, meaning "Castle at Full Size: Big Boss"): By raising his pinky and middle fingers, Bege transforms his entire body into a gigantic, heavily armed and fortified fortress-like golem, towering even the massive Big Mom. The golem has a large number of cannons that can fire from various points in its body. The golem has immense defensive capabilities, and can easily resist cannonfire, and is resilient enough to withstand being smashed apart by an enraged Big Mom, who could easily destroy cities and sink battleships, for a limited period of time. However, it is still Bege's body and any damage done to it still injures him, and should it be destroyed, Bege himself will die and anyone within will be thrown out into the open.[5] This was first used to protect all his allied forces after the assassination attempt on Big Mom failed.[6] In Voller Größe is German for "In/At full size". It's name in the Viz Manga is Full-Scale Rook!!: The Big Father


  • The Yami Yami no Mi, Numa Numa no Mi, and Blamenco's ability are similar to this fruit, as the four of them create a space inside the user's body where things can be stored. The main difference being the Shiro Shiro no Mi is a Paramecia type while the other two named Devil Fruits are Logia types.
  • In the banquet hall of Capone Bege's castle body, there are pictures of himself hung on the wall.
  • This is the second Devil Fruit used by a Supernova to be named (other than Luffy's), 304 chapters after its initial appearance,[2] the first being Trafalgar Law's Ope Ope no Mi.
