Kakuto (格闘) - Female Boxing Game
This one isn't anything particularly exciting but its a cute little game that Houkodou made several years back shortly after finished Boxer Girl's Little Adventure.
The premise is pretty straightforward; you have a stamina bar that slowly refills and you can attack using three different punches. There isn't much of a difference if you win or lose so enjoy this video of two devil girls slugging it out!
