Who is that girl in the devilishly cute maid outfit with a pair of Uzis? Why it's Mir your new queen of Slytherin House, master of cosplay, yaoi dojins, casual nudity and Cutey Honey style transformation, and genocide.

Yes, she is a bigger mass murderer than Voldermort. Yes, probably bigger than Hitler. No, she is only here to lower the number of points for her house by disregarding the uniform code in favor of her own personal style. She is not going to identify with the arrogant, inbred losers who fancy themselves hot-shit in her house. For one thing, she's way too arrogant for that.

She is here to corrupt the youth and redeem herself a little bit.
