"Geass" is a supernatural power granted to those deemed worthy of wielding it. While its specific effects vary according to the user's wishes, those who command it possess devastating strength. In the distant region of Area 11, formerly Japan, the sharp-witted 17-year-old student Lelouch Lamperouge receives his own Geass from the enigmatic woman C.C., granting him absolute obedience over anyone upon whom it is used. Armed with this ability, Lelouch vows to dismantle the sole world superpower—the Holy Britannian Empire—operating under the alias of the revolutionary freedom fighter Zero, to seek vengeance against those who destroyed him and his family.
