Code Geass / Ohkouchi, Ichirou

The Black Knights travel to Area 11 to take back control of Japan, but when Lelouch learns that Nunnally has become the viceroy for Area 11, he is obligated to send his friend, Suzaku, to rescue her.

Now that Lelouch is Emperor of the Holy Empire of Britannia, his and Suzaku's promise to create a kinder and gentler world is realized, but he will have to fight to hang on to that world.

Mao, a new Geass user, appears after Lelouch strikes a devastating blow against the Britannian Forces, and must continue in his quest even as the world starts crumbling around him.

Lelouch, a Brittanian in Japan after the Holy Empire of Brittania conquered the country and renamed it Area 11, vows to demolish his own government, and meets a girl who bestows him with the power of Geass, which allows him to control people's minds and become the terrorist known as Zero.
