What is C code: Definition and 33 Discussions

C.C. (シー・ツー, Shī Tsū, pronounced C2) is the pseudonym of a fictional character in the Code Geass: Lelouch of the Rebellion franchise by Sunrise. With her real name kept from the audience, she first appeared in the 2006 initial anime season, and afterwards has appeared in many manga, OVA, anime, and video game spinoffs. She is voiced by Yukana.
Introduced as a captive human test subject of the villainous Holy Britannian Empire, C. C. is revealed to be an immortal young woman with special powers called the Geass. Sardonic, stubborn, and mysterious, she can give Geass powers to others, which she does to main protagonist Lelouch Lamperouge. She becomes an ally and protector of Lelouch, at times piloting a mech and leading the paramilitary group the Black Knights to do so. She later assists Lelouch at destroying other Geass users misusing their powers, including her former students, and supports the regime changes that follow.
In the 2006 Anime Grand Prix, C.C. was awarded third place for most popular female character, then first place in the following two years.
