From BH007:nMika's sister gives her a mirror that supposedly grants her any wish she deisres, so she wishes for a world where boys don't get perverted thoughts when looking at a girl. The result? Mika is thrown into a world where girls happily walk around topless! What's more, wearing panties is considered perverted and girls who walk around with a top without good reason are chased down and punished! nNow that's only the first of Mika's many bizzare adventures, thanks to her sister inventions!
