まい

The middle sister. Although she is the middle sister, Mai governs household affairs such as the budget. She longs to leave the mansion but does not want to burden Ai whom she knows does not have the willpower to deal with such responsibilities. Mai has a tomboyish personality and is very short-tempered, especially when it comes to Chris, the more so when she thinks she'll lose face. She is the only character who vehemently opposes Chris's staying at the mansion. [Edited from Wikipedia.]
