One Piece Odyssee

The Mune Mune no Mi grants the user control over their chest area, allowing them to store, compress, and retrieve objects of any size within a pocket dimension inside their chest. In combat, the user can unleash hidden weapons or traps instantly. Outside battle, it’s perfect for smuggling, carrying supplies, or disguising equipment—making the user a living vault. Storage is weightless, but space is limited by stamina.
