Lelouch has overtaken the empire, establishing himself as Emperor. He starts by abolishing the aristocracy and announcing Suzaku as the Knight of Zero. Lelouch announces that Britannia will join the U.F.N., but Schneizel makes an unexpected move.

The Black Knights fight a close battle with Schneizel, neither side giving way. Before the F.L.E.I.J.A.'s can destroy them all, Lelouch must outsmart the brother he has never beaten and face the sister he has spent his life protecting.
