Mai is the main character of a Prequel Manga called "Remix Heart". In Truth, Mai is actually a man that was permanently transformed into a woman thanks to the "Pure Grimoire". Mai's Centralfiction profile describes her as being cheerful and positive, sincerely caring towards others, that she values her friends above all else and that she often neglects herself due to the strength of her feelings. She has completely gotten used to being a woman at this point, although still dislikes the clothing she is subjugated to, mostly due to her body type. Despite this, she still speaks in a somewhat masculine manner, similar to a young boy.
