In this alternate-universe manga, an explosion separates the blind, wheelchair-bound Nunnally vi Britannia from her brother Lelouch just as the Holy Britannian Empire tightens its grip on occupied Japan, renamed Area 11. A mysterious sentient doll named Nemo gives her a personal Knightmare Frame and a Geass power of clairvoyance, thrusting the peace-seeking princess into direct conflict with rival Geass users and the vigilante Zero while she searches for her missing brother.
