ナナリー・ランペルージ

Nunnally Lamperouge is Lelouch's younger sister. Originally born as Nunnally vi Britannia (ナナリー・ヴィ・ブリタニア). Injured in her mother Marianne's brutal assassination, she is wheelchair-bound and blind from psychological trauma. It is on her behalf that Lelouch pursues the destruction of Britannia and the forging of a peaceful world. Following her return to the Imperial Family in the second season, she retakes her birth name, Nunnally vi Britannia, and is at her own request appointed Viceroy of Area 11. [From Wikipedia.]
