Lelouch Lamperouge's ambition to topple the Holy Britannian Empire is gradually collapsing. His sister Nunnally has been seized by Schneizel el Britannia, while Suzaku Kururugi refuses to heed his urgent calls for help. The Black Knights are increasingly losing confidence in Lelouch as their commander, and the United Federation of Nations has declared worldwide war against Britannia. After enduring repeated betrayals, a marked loss of influence, and mounting hatred toward Emperor Charles zi Britannia, the wounded Lelouch resolves: if he cannot crush the Empire from outside, he will seize it from within and rally remaining allies together today.
