Lelouch's sister. She was kidnapped by V.V. during the Black Rebellion and went missing, but she returned to Area 11 as the new viceroy, being the 87th in line to the throne.
After that, she worked hard to achieve an innovative way to govern, such as suggesting the re-formation of the Special Administration Zone of Japan.
She was thought to have died in the explosion of the F.L.E.I.J.A., but she was saved by Schneizel. She then reappears in front of Lelouch as his enemy, being in support of Schneizel becoming Emperor.
