Being forced to carry his innocent sister through a sea of bodies would have broken much older men. For Lelouch, it merely strengthened his resolve. But he was only human, and let his mission slip to one other. Confronted with the possibility of failure and staunch allies in his corner, he swallows his pride and actually prepares himself for his rebellion. AU, harem— Fanfiction Dot Net summary.
Code Geass: The Prepared Rebellion
is a Code Geass Fan Fic that is a mix of Alternate Universe Fic and Rational Fic written by SeerKing.
Lelouch has sworn to destroy Britannia in the aftermath of the Invasion of Japan. However, he has gone a step further and (initially somewhat reluctantly) taken up physical exercise and reading up on battle tactics so that when he begins his rebellion, he isn't as physically weak or as tactically inflexible as he was in canon. Nor is he the only one who is acting smarter and more rationally: Ohgi, Jeremiah, Kallen, Milly's grandfather Reuben, and Sayoko, among others, are also more rational in their thoughts and actions with few exceptions.
