The advanced battles classroom, as taught by Tetsu Hageshii, is a simple classroom. There are student desks, and a teacher's desk with a stack of papers, but everything seems to be covered in dust. The room is rarely used, and actually, forever written on a chalk board is a message: "Meet at the heavy duty arena... -Hageshii-sensei"

This is where the actual class takes place, rain or sleet, or hail, or shine, so students are advised to come prepared for the worst. The arena itself is made of heavy duty, thickly pounded earth, strewn with rocks, with just a few tufts of grass and weeds trying to grow, despite the ferocious battles which take place. This is where students are broken, and turned into champions. (Yay overly dramatic description!)
