Euphemia Margaret li Britannia (ユーフェミア •マーガレット• リ • ブリタニア Yūfemia Māgaretto ri Buritania), born Euphemia Walpole (ユーフェミア • ウォルポール Yūfemia Worupouru), 13 years old (14 at R2), is the fourth princess of the Britannian Imperial Family and is Lelouch`s half-sister. Much like her older sisters, Cornelia and Euphemia, Margaret is extremely skilled in Knightmare Frame combat, and helped Cornelia complete the establishment of Area 18 shortly before they both arrived in Area 11. She serves as one of the main antagonists during the first season but later becomes a neutral character during the second. When she was only a baby, the E.U kidnapped Euphemia on the night that Marianne vi Britannia was assassinated with her being adopted into the Walpole Family. She was rescued when she turned two, and has been slowly integrated into the Britannian Imperial Family over time.


Euphemia is as beautiful as she is cold and detached on the battlefield, with long pale-blonde hair
