Behind the mask of Zero is Lelouch Lamperouge, a Britannian student who uses an extraordinary power to pursue revenge against Britannia. His campaign unfolds in Japan, which the Holy Empire of Britannia conquered in 2010 as it began establishing its military dominance. Renamed Area 11 after its rapid defeat, the country remains a site of armed resistance seeking independence.
Lelouch becomes involved when he is caught in fighting between Britannian forces and Area 11 rebels. A mysterious girl named C.C. enables his escape and grants him Geass, a power that allows him to command absolute obedience. Recognizing what this ability makes possible, Lelouch adopts the identity of the masked vigilante Zero and launches a ruthless offensive against Britannia.
