The second prince of the Britannia Empire. He also serves as Chancellor.
He is a brilliant strategist, and due to him the EU lost many of its territories. He is also involved in issues other than politics, and supported the ASEEC and Nina's research.
He is the only one Lelouch couldn't beat in chess when they were younger.
During the Second Tokyo Battle, he negotiated with the Black Knights and succeeded in tearing Zero away from the Black Knights. When he reported the situation and turn of events at Area 11 to his father, the Emperor brushed them off as mundane affairs. That statement was the last straw in his resentment, and he decided to become Emperor.
