After Lelouch and C.C. enter the mystical "Sword of Akasha" spirit realm, she reveals to him that her greatest wish is to die by giving up her Code. Since Lelouch is not ready to accept it, she intends to offer it to his father, Emperor Charles. Lelouch attempts to stop her and save her, and in doing so, her memories of everything after the day she acquired her Geass are lost, reverting her to a frightened slave girl. Believing himself to be responsible, Lelouch confines C.C. to his quarters and attempts to make her comfortable. Later the spirit of Lelouche's mother, Marianne, possesses a body and locates C.C. to restore her memories. The two then leave for Kamine Island to re-enter the Sword of Akasha, rescuing Suzaku Kururugi along the way. They enter the "Sword of Akasha", where C.C.'s presence allows the Emperor to begin the Ragnarök Connection and merge everyone into the collective unconscious. When Lelouch kills Charles and Marianne before the connection can be completed, C.C. is spared because she had turned against their plan. A month later, she helps Lelouch seize the throne as the new Emperor of Britannia.
