Booty Royale: Never Go Down Without a Fight! Vols. 11-12 (manga)

The all-woman (and one robot) Ultimate Beauty and Power Showdown is down to the final four! But first, K-cup karateka Haebaru Misora has the chance to get down with her new comrades-in-fist before facing them in the cage, thanks to the machinations of a peculiar and perhaps pervy billionaire. Will Misora make it past her semifinal opponent to sing in the climactic aria of the Valkyrie Opera, and if so, whom shall she face: the P-cup judo queen Alevtina Guseva or the mysterious and ultraviolent lethwei genius Maomao? Someone has a crush, and everyone else is gonna get crushed! Place your bets!
