C.C. (pronounced "C2") is the tritagonist of the anime/manga series Code Geass. She is an immortal woman and the former leader of the Geass Order that abandons the order and allies herself with Lelouch vi Britannia, granting him his Geass power and becoming his right-hand.
C.C. is serious, solemn, and emotionally cut off from the world. For being betrayed in the past, she feels she cannot form a meaningful connection to anyone and only allies herself with others out of the pragmatic desire to reach her goal of ending her own life. Despite this, her time with Lelouch allows her to begin breaking down her emotional barriers, eventually learning to care for others again and see the value in her life, even making her experience what love feels like, an emotion she is unfamiliar with up to that point.
She also has a somewhat obsessive penchant for pizza, especially Pizza Hut's Cheese-Kun. Her love for pizza is so strong that she is willing to risk herself getting captured, twice nearly exposing herself to get a piece of a giant pizza made by the Student Council—which ruined both times.
