The aftermath of the Avalon's arrival inexplicably leaves Lelouch, Euphemia, Kallen, and Suzaku on the mysterious Kamine Island. Suzaku encounters Kallen, and learns she is a Black Knight and the pilot of the Guren, while Euphemia is found by Zero, confirming her suspicions that he is Lelouch. Meanwhile, Schneizel, Lloyd, and Cécile Croomy survey the island's ancient ruins. When Lelouch, Kallen, Suzaku, and Euphemia suddenly fall into the ruins, Lelouch and Kallen steals the Knightmare Frame Gawain to escape. As Suzaku is detained for insubordination, it is revealed that Lelouch used Geass on Suzaku, giving him the command to live, through which he prioritized his own survival over Zero's capture. Elsewhere, the exiled Japanese government from seven years ago launches a full-scale assault on Kyūshū with the help of the Chinese Federation.
