That summery leaves a lot to be desired, I don't even really have enough info to ask questions to find out if this is a game I would be interested in. Like is it saying there are 3 girls and the rest are futa? or is it a different game mode? Is it saying the getting cucked is if you lose a battle? Or is it just somthing that happens. What is the base premise even, just collect them, for what reason? Its a trainer, what are you training them for, to be yours, to be whores, you put it under a spoiler tag but it doesnt even really give any details.
As is this is ether a I will for sure play, or a hell no, and yet I have no clue from such generic descriptions.
