Knight the First, and the strongest knight in the empire. He rides the enormous Knightmare, "Galahad," and wields the huge sword "Excalibur" (larger than a human being) that was personally given to him by the Emperor.
He hides the power of Geass, one that can predict the immediate future, in his left eye, but he sealed it because of his loyalty toward the Emperor and Marianne.
He leads the Knights of the Round to defeat Lelouch who killed the Emperor, but meets his death in a fierce battle with Suzaku.
