Pretty Mahjong Soldier Mu
Publisher: Apple Pie
Caveats: Anal, Bondage, Outright Weirdness
I am convinced that this game was made specifically to fuck with your expectations in terms of hentai content. In this game, a blonde Sailormoon look-alike is given magical mahjongg powers by an alien she rescues from a group of hooligans. She must then roam the town challenging weird characters to strip mahjongg, such as a crossdressing bodybuilder, a naked Kekko Kamen parody character with dildo nunchaku, and an android lady in the style of Ultraman. You learn to expect the unexpected as the strip scenes progress for the opponents, although Sailor Mu herself doesn't strip. She does, however, seem extremely eager for her opponents to do so if she wins.
