So I was re-reading through posts, both OOC and IC cause I'm checking to see who's officially dropped out by now and I noticed something in the IC. Juju, I had completely forgotten that you had re-written your intro post and I'm sorry to say this, you're going to have to again, specifically for the classroom bit. Yamaku Academy is an extremely anachronistic school, much more than you described in your post, just to give you all examples, here's what it looks like is is described as.
katawashoujo.wikia.com said
"Hisao, upon first seeing it, comments on the gate being too 'pompous' for what it is."
"Despite having a 'grand' exterior, classrooms and other areas appear quite plain and simple, with basic wooden desks, old windows and classic blackboards (but as Hisao would say: 'Simple and efficient.')."
And there you have it, and for those of you who don't know the dress code
Boys: white collared shirts, black ties, green slacks, dress shoes, blazer is optional
Girls: white blouses, green skirts, knee high socks, dress shoes, black bow ties (or whatever they're called)
In some cases though, some girls tend to wear the boy's uniform.
