The Sabi Sabi no Mi is a Paramecia-type Devil Fruit eaten by Shu, a Marine captain.

This fruit allows Shu to rust and corrode metal on contact, including weapons and armor. During the Enies Lobby Arc, Shu uses this ability to destroy swords instantly, posing a serious threat to weapon-based fighters.

The effect is limited to metallic materials, making the fruit highly situational but extremely dangerous in the right matchup.
