This is the opening movie for Senran Kagura Burst on 3DS. In the words of Jonathan Holmes, "I've never seen something switch from totally awesome to totally stupid so rapidly."
It begins with your typical "stare longingly out into space" bit common in anime intros, followed by a chick's lifting around five tons of barbells above her head, followed by another girl's blowing up a tank with Oswald Cobblepot's umbrella then shielding herself from the resulting blast with said umbrella.
Later, two other gals disintegrate one another's clothing by the shock waves formed by bumping their huge bubble butts together.
DJ Assault would be proud.
