In the aftermath of betrayal and tragedy, Lelouch and Suzaku stand at gunpoint—friends turned enemies over the death of Euphemia. But before either can pull the trigger, a mysterious young girl appears, claiming to be the daughter of Lelouch and Kallen—born from the experiments of the Geass Order. Calling herself A.A., she wields a power unlike any other: the Geass of Time Travel. As A.A. reveals her origins and grants Kallen a new dual Geass—Absolute Fate and Absolute Truth—the trio is thrust back in time to the moment before Euphemia’s fatal command. With history rewritten, Lelouch faces a second chance to right his greatest mistake… and to uncover the true cost of Geass itself.
