If I had to go back, I would want to go to Fumizuki Academy from Baka and Test. 阿凡达 battles would make test taking a lot 更多 fun. I'd probably be in class B, where I'm sure the accommodations are nice.
I wanna go to the IS academy in Infinite Stratos. I wanna be the 秒 male to control an IS. Maybe become 老友记 with the main characters in it :) Maybe I think it's fun to be in this school because everyone is female (because there is only one male to ever control an IS). It is just fun to be in this school.
