On August 10, 2010, a.t.b., the Holy Britannian Empire declared war on Japan and subsequently conquered it. Seven years later, teenage student Lelouch Lamperouge finds himself pulled into a battle between anti-government terrorists and the Britannian Army in the Shinjuku Ghetto. In the midst of the conflict, a mysterious, green-haired girl saves him from death by granting him "the power of the king," which allows him to compel others to do his bidding.
