Agent Mirai and the Submission Machines

You're just a guy who loves fighting and martial arts. You trained hard and earned yourself quite a reputation, winning one competition after another. Bored with your college routine and the lack of challenging opponents, you decide to enter an underground fighting tournament. What will be your surprise when it turns out that you will be facing a female opponent…
 
Losing to her could change your life forever. Not only would it shatter your confidence as a fighter, but it might also provoke an unwanted (or wanted) reaction from the girls around you. They once respected you, but now they might see you as a sick pervert who enjoys being dominated and bullied by them.
 
Have you ever thought, “Damn! I want that chick to crush my skull between her thighs!” ?
 
Well, then...
 
UnderGirl: SP is a femdom-centric game in which you will have to fight beautiful girls in order to get your pride back to where it belongs! It has a simple fighting system with five directions to block. Look at your opponent and try to guess which attack they are going to use and then intercept it! Be careful though, they won't hesitate to use all the dirty tricks at their disposal to make you squirm.
 
Keep in mind, if you make some very bad choices, the fight can end worse than just a small loss to your record. Remember, in the underground fighting community, there are no rules or guidelines to follow. It might be over for you before you even realize what hit you.
