Pluton

The Pluton ( プルトン, Puruton ) is a secret organization of the Holy Britannian Empire that has carried out black operations for the Britannian Imperial Family for generations. It is led by the Zevon noble family, and was under the leadership of Oiagros Zevon. Some time after, Oiagros abandons his position, and V.V. takes control of the organization.

Organization History
Not much is known about Pluton except that it undertakes secret and dirty jobs for the royal family. One such job was attacking a village in southern Hungary and killing all it's inhabitants to eliminate two escaped test subjects from the Geass Order, Orpheus Zevon and his lover Euliya. They were present during the Assault on the Geass Order when they confronted Benio Akagi in their Sutherland Pluton Custom and nearly cornered her when they shot the Benihozuki's Radiant Wave Surger until when they were shot by the group of Akatsuki trying to back up Benio.

After V.V.'s death, it is possible that Charles took over the organization until his own death.
