Game: Yakyuken
Difficulty: 4
Nudity: 4

A game of yakyuken versus a schoolgirl in a naughtily-short uniform amidst a galactic background. Although I suppose the artwork is okay for a Nintendo-era game, the game itself uses a random reflex test for you to hit the button when your gesture will win, rather than an actual RSP system, and has the annoying feature of having the girl win back clothes on ties while you can do no such thing. Also, at certain points of the girl’s state of undress, animals appear out of nowhere to challenge you before you can continue to strip her. This game was later translated to English by a hack of the disk image.

Supposedly there is also a version for the PC-88, but we have yet to confirm its existence.
