Guinevere su Britannia (ギネヴィア・ス・ブリタニア, Ginevia su Buritania) is the First Princess of the Britannian Imperial Family. She is referred as Britannia's Marie Antoinette, due to the fact that she likes to spend her wealth on extravagant monuments and buildings. She has a tattoo above her left breast. After the one month time skip she is seen in the royal court, whom Lelouch uses his Geass to compel her and everyone in the Royal Court to accept him as the new emperor. She is then employed as a maid along with most of the female royal line. Her fate after the F.L.E.I.J.A.'s use on Pendragon is unclear.
