Euphemia-euphemia li britannia
Euphemia li Britannia (ユーフェミア・リ・ブリタニア, Yūfemia ri Buritania?) is Lelouch's half-sister and the Third Princess of the Holy Britannian Empire. She is a kindhearted and open-minded woman who despises conflict in any form. Euphemia joins her older sister Cornelia in governing Area 11, becoming the Sub-Viceroy. She develops a relationship with Suzaku Kururugi, whose views reflect her own, and eventually appoints him as her personal Knight.
