One Piece Wiki

The Jara Jara no Mi is a non-canon Paramecia-type Devil Fruit that allows the user to grow chains from their body, making them a Chain Human (鎖人間 Kusari Ningen?). It was eaten by Mad Treasure.[1]


  • Jarajara (ジャラジャラ・じゃらじゃら?) is a Japanese onomatopoeia for the jangling of metal, such as chains.
  • The FUNimation sub names this fruit as the Chain-Chain Fruit.

Strengths and Weaknesses

The chains granted by the fruit can be used as powerful blunt weapons, should the user be able to wield them effectively. The chains can also be used as a sort of armor for self-defense. The user is also capable of tying things up with the chains, and tightening the chains telekinetically (the chains he does this with glow red). The ends of the chains can be made sharp, allowing the user to stab opponents and latch onto faraway surfaces. The user can make the chains various sizes from being the size of a average chains to being large enough to act like a bridge.[2]

Although the chains are strong, they can be broken with sufficient force. Otherwise, the user is affected by the standard Devil Fruit weaknesses.[2]


Mad Treasure uses this fruit in combat, attacking people in a variety of ways. He also uses it to chain people up and capture them, and can crush them with the chains. His chains can also come in alternative forms, such as accessories like necklaces, sashes, and collars, which he use to make people do what he wants by tightening them. The chains can also have different kinds of ends, such as large claw-anchors to latch onto things or weights increase the power of their strikes. Mad Treasure can change the metal or material the chains are made of since he has been shown changing his into gold along with stating they can be changed into diamonds to further boost the chain's offensive and defensive capabilities.[2]
