I'd love to see it too, but the problem is that it's hard to find a recognizable cos. Except for their school uniforms (which aren't that different from "generic school uniform", at least for the guys), most of what they wear are simple everyday clothes. =/
(One of these days, it'd be fun to do Arima Reiji... but I don't know what to wear that would distinguish him from any other "guy in a suit".)
