One year after the events of the season 1 finale, Lelouch returns to Ashford Academy, having no memory of his time as Zero, his Geass power, or his sister Nunnally. The Black Knights were defeated in the Battle of Tokyo, and all but a few of them have been captured or killed. The remaining Black Knights, along with C.C., find Lelouch and help him regain his memory. Afterwards, Lelouch resumes the role of Zero while attempting to hide the fact that his memories have returned.
