Code Geass: Nightmare of Nunnally

Code Geass: Nightmare of Nunnally is a manga series that reimagines the alternate-history narrative of the popular Sunrise anime series Code Geass: Lelouch of the Rebellion. Serialized in Comp Ace beginning in 2006, the story shifts the central perspective from Lelouch vi Britannia to his younger sister, Nunnally. While it shares the fundamental premise of a Britannian invasion of Japan, the narrative diverges significantly by introducing a unique supernatural element known as the Nightmare Frame Mark Nemo, which Nunnally pilots to navigate the geopolitical conflict.

The manga was authored by Tomomasa Takuma under the creative supervision of Goro Taniguchi and Ichiro Okouchi, the original creators of the anime. The design direction sought to contrast the gritty, tactical nature of the anime with a more personal, character-driven journey, utilizing a distinct art style that emphasized the psychological weight placed upon Nunnally. The series was generally well-received by fans of the franchise for its willingness to experiment with the established canon, offering a darker and more introspective take on the series' core themes of resistance and rebellion.
