The Rerumu Rerumu no Mi is a Paramecia-type Devil Fruit that allows the user to manifest the aspects of the Six Realms and control their properties as long as they are currently in usage of the certain realm, turning the user into a Realm Human(レルム人間 Rerumu ningen). Rerumu(レルム) means "realm". It was consumed by Mugen's leader and Shukketsu Clan member, Shukketsu Raudo. After the Timeskip, Raudo was able to find the fruit within the Underworld and consumed it. After consuming the fruit, he spent his time trying to master the fruit in hopes of furthering his endeavors with its powers. Despite not currently being a master of the Devil Fruit, Raudo has shown to be very proficient in its usage, as some could consider him a prodigy with the fruit.
