They have found a way for you two to help with the negotiation!

You enter the office and see the two men standing over some paper's at your Master's desk. You can tell that both men have a long history of cooperation and rivalry that goes back many decades. Each seems to be making an excellent case for why their females are worth more than an equal trade with the other. Both are passionate in their arguments and both seem to enjoying the act of robust debate. You carefully listen to their discussion and realize that he is Zankoku Shigaraki. This is Yoshino's father!

You study Master's visitor as you and the other girl wait patiently for them to include you in the discussion. He is shorter than Master but still towers over you at 6'5". He is old, like Master, but his body shows incredible strength. Large muscles bulge beneath his suit. It appears he has less of a gut than Master. His face is relatively handsome, but a large scar cuts across his right eye. He has deep Asian facial features, a thin beard, and black hair. He embraces your Master in a great big bear hug before turning and addressing you and the other girl.

"Girls, we have been struggling to agree on a going rate for our exchange of females... but we might have found a way you can help us decide! Both of you will represent your Master in a game. In this game you will be able to demonstrate the prowess of the females within our harems. We will finally know who's females are worth more. The winner will receive girls at a two for one rate!"

Master looks at you with pride, but you are afraid. You had better not fail your Master.
