He attends the Ashford Private Academy in Area 11.
He has a sharp mind and is the Student Council Vice President.
Suzaku captured him during the Black Rebellion, and the Emperor of Britannia sealed his memories, but C.C. reawakened him as the demon. He then announced the formation of the "United States of Japan" once again.
Later, he strategizes with the Chinese Federation, destroying the Geass Organization, but one by one he loses the people who are close to him and finally he is sold out to the Britannian Forces by the Black Knights. He loses everything and once he had lost his dear sister Nunnally, he was determined to kill the Emperor of Britannia, the source of all his misfortunes. He then went to Kamine Island and killed his father and also his mother, who had revived due to the power of C's World.
And then, he became the 99th Emperor of Britannia... Lelouch vi Britannia.
