Character History[]

Mao is mentioned by Alice that she used to be an Irregulars member just like her, before she left she took a large amount of Neutralizer with her. She first appears in chapter 11 in Nightmare of Nunnally trying to remove Nemo from Nunnally. Because C.C.'s cell matter causes cellular breakdown, she seeks to steal Nunnally's bond with Nemo, which she believes to be a possible cure. After Alice breaks Mao's remaining suppressants, before she died Mao curses Alice letting her know that this is the fate of all Artificial Geass User, then her body turn to dust and finally died.



Her Geass the Refrain in addition that it allow her to read the mind of other people and control it, it allows her to render her victim catatonic by forcing them to relive past experiences, similar to the drug in the anime it is named after. As an Artificial Geass User just like the rest of the Irregulars she also receive the same weakness as the rest of them, the C.C. Cell inside her will eventually reject her body causing the host to died from the process.
