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 to crush my skull between her thighs!” ?
Well, then...
UnderGirl is a femdom-themed 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.

Thank you everyone so much for your support this year. Honestly, at the beginning, I couldn\'t even imagine that I would be able to ship a whole game and receive as much attention as I did -- drawing stuff and make videogames are things I allways wanted to do It all makes me very happy and inspire me to create more! So I promise to not back down. I have big plans for 2026, even though I work slowly and spend a lot of time on other things, mostly IRL problems.

Today is Mila\'s birthday!
You fear her, but youre fascinated by her. You want to fight her, but you dont want to die. Its time to wish Mila a happy birthday!
By the way, does anybody know why she left the military, anyway? It wasnt mentioned in the game! D-Does it mean? Could it mean Mila has a lot more cooking up for her content-wise outside of UG:SP?

Hey there, cuties~ Katsumi here! We really need to talk about your, uhh... not-so-secret replaying of my gameover scenes over and over again. The game was released over 3 months ago, but the average number of daily active users still stays around 42 even now! You must really like me, huh? Huuuh?
Well, nows your chance to prove your never-ending love for a cute girl like me! This \"Steam Awards\" thingy sounds fitting for that. Kado really worked her butt off with the visuals, you know! And the mechanics. And the story... well, pretty much every aspect of UG:SP.
Hey, what do you mean we wont win?! What do you mean there are games way bigger than ours?! Shut up right now or Ill bonk you! Katsumi never loses!!! You should know better.
