Code Geass follows the path of Lelouch as he embarks on his quest to get revenge against the Britanian royal family, his own family, for the murder of his mother and the crippling of his younger sibling Nanaley. Good things can come from the worst of intentions, and bad things can come from the best intentions. Which Lelouch is doing is unclear.
On his journey he meets a strange being that is not of human kind. Her name is C-2. She makes a contract with Lelouch and gives him the ever evolving power to controll peoples minds. One question remains, will he take the to creating a perfect world in which Nanaley can live safely, or the path that leads only to death and destruction.
