World Noble

The World Nobles, also known as the Tenryuubito, are the descendants of twenty kings who destroyed the Ancient Kingdom eight-hundred years ago and established what is now known as the World Government. These are the people who are allowed to live in the Holy Land of Mariejoa. They can be sometimes seen walking around Shabondy Archipelago, but are disconnected to the point that they wear bubbles over their heads to prevent from even breathing the air of the common people.

The Tenryuubito have various rights and privilidges not held by many other people in the world. In particular, they are able to buy people, including pirates, who have been captured and put into slavery. It is said that no matter if someone is killed right before your eyes, you should never oppose the world nobles. Those who do are immediately reported by them to one of the 3 Admirals: Aokiji, Akainu or Kizaru.

Saint Roswald is one of the Nobles.

They are first mentioned in chapter 496.
