Vagina Quest -Maam no Daiboken- / ヴァギナクエスト~マァムの大冒険~

When evil reigned, humanity was united... but now, in a time of peace, human-on-human crime is on the rise. Murder, r*pe, molestation, larceny and petty panty thefts... Maam does what she can to make the world just a little better by fighting criminals on her own. Then she receives a letter that says the princess has been taken hostage. Maam sets off on a tragic journey.
The Great Demon has already been defeated, so enemies are weak. You don't have to worry about leveling up (unless you change parties). Maam will provocatively lose her clothes from battles.
