Lelouch Lamperouge is an exiled Britannian prince who was sent as a bargaining tool to Japan, along with his sister Nunnally Lamperouge, by his father, Emperor Charles zi Britannia, after his mother, Marianne vi Britannia, was killed. When Marianne was murdered, Nunnally was set up as a false witness. Because of this, her sight and her ability to walk were taken from her. After the war in the ruins of a Japanese city he then vows to his Japanese friend Suzaku Kururugi that he will one day obliterate Britannia. Seven years later, Lelouch gets caught up in a terrorist attack and finds a girl called C.C., who saves Lelouch's life from the Britannian Royal Guard, by making a contract with him that grants Lelouch a power known as Geass.
