After the Mark Nemo pilot was captured, Suzaku was approached by Lelouch, who was shocked when he revealed the pilot was Nunnally and had no choice but to help him, and later passed the information to Euphemia. Suzaku, along with Lelouch as Zero, arrived on time to stop Nunnally from being executed by her "other" brother, Rolo Vi Britannia, on Euphemia's orders and proceeds to fight Rolo and his knight, Anya Alstreim, only to be defeated by Anya's "Tristan" Knightmare Frame. After Alice flees with Nunnally and Emperor Charles zi Britannia declares the Holy Nation of Eden Vital, Suzaku is arrested along with Euphemia, Cornelia as well as his comrades Guilford, Lloyd and Cecile. He is rescued by Zero and, despite his mistrust, helps him make Euphemia the Empress of Britannia. Having lost his original "Lancelot", Suzaku deploys the "Lancelot Albion" with Zero in his "Gawain" against the Emperor's Knights of Rounds (who are revealed to be undead zombies). Suzaku and his "Albion" are almost defeated, but are saved by Charles' defeat. At the end of the series, Suzaku remains as Euphemia's knight and the two of them meet Lelouch for the last time when he appeared to them in Euphemia's office to bid farewell.
