the man with the black tie is the head: principle Yuhiko ( it's a japanese school btw, obv,) he's half english and has a somewhat unique approach but he's a good headmaster, I think. FYI, Yoko is japanese. Tani is half japanese, half Maori ( Maori is the native newzealanders. Tani is a maori name...yeh...)

thought I'd just give some background since it may be confusing that in a school in Osaka the charas constantly use pommi/british slang. xD
