A short one-off art piece from Masaaki Yuasa that focuses on distinct animation to tell the story, rather than dialogue. Short enough that it's definitely worth checking out, even if the style is vastly different from typical anime fare.
While it's literally the same plot as the series, the action and animation are improved (though some action is as believable as a Fast and Furious movie). It has a vibe of watching an eSports match, just with very Moe anime girls.
A feel-good sports anime starring cute girls in tanks. It feels like a war tactics game, like Valkyria Chronicles or somesuch. I enjoyed this more than I anticipated.
