Here is the formula: play as a pretty lady with some serious weaponry, such as pigtails with rotating blades. Clear a small section of the stage by taking on hordes of adversaries, often fellow ladies. Progress through the level to meet the boss. Power up and reveal (via an anime sequence) a skimpier outfit and seemingly boosting your stats other than your vital stats. Give boss a good beating and cause her to lose items of clothing (again via anime sequences.) Defeat boss, end level. Stylishly done with a real aplomb and an appreciation of the mass market as much as the doujin title. Hats off (and not just to protect the boss' modesty.)
