> magical girls drafted into the military as special aerial assault forces
> using magic to fly, can do maneuvers such as breakneck turns, speed bursts, sudden braking, and midair hovering Something like Star Fox in 6DOF I suppose
> outfitted with both magic wands, machine guns, and melee for straight up aerial jousting with other witches
< Nazis get lances, English get longswords, Nips get folded one gorillion time katana, Ruskies get Shaskas
> Short range combat can lock in to engage in Dragonball Xenoverse style fighting
I would play the shit out of this
