During Bandai's short time as a manga publisher, they put out a ridiculous number of Code Geass manga, including many anthologies and AU spinoffs. This one might be the most radical premise of the lot, but that only makes its mistakes all the more disappointing.
CODE GEASS: NIGHTMARE OF NUNNALLY, based on the original story by Ichirou Ohkouchi & Goro Takiguchi, with art by Tomomasa Takuma. First published in 2007 and first published in North America in 2009.
PLOT:
Despite the loss of her mother, her family's prestige, her sight, and her ability to walk, Nunnally vi Brittania takes faith and comfort in her life from her older brother Lelouch. When her brother disappears during an incident with Brittanian soldiers, Nunnally encounters a strange doll called Nemo that grants her wish for power to help herself, giving her the ability to temporarily move and see while encased in a bizarre mechanical suit. As the conflict between the armies of the Brittanian Empire and rebel forces within Japan escalate, Nunnally finds herself wondering if her new power is a gift or a curse...
