Girls und Panzer
You may have heard of kung fu, but the girls at Oarai High School practice gun-fu - really, really big 75mm gun-fu, in fact. It's called Tankery, and it's the martial art of operating armored tanks!
They take it seriously too, and since winning the national Sensha-do championship is such a huge deal at Oarai, they sometimes go to extreme ends in order to get the best students from Panzer class to sign up.
They may not be on the half-track to fame and fortune, and maybe a few of them would rather shop for tank tops than become tops in tanks, but once their focus is locked and loaded, they're absolutely driven.
