Just beat Katrina and recieved an offer to be her eternal slave. Upside, lots of spankbank material in serving the mistresses assuming every domina will give that offer. Downside, it becomes impossible to finish the game when the MC accepts the offer, because she will keep you in her realm for eternity without ever getting the chance to leave again. A thought just occured, after beating all 13 you could get one of 3 choices, #1:- you fufill your duty to the goddess of light and she restores your human life for a happy ending. #2:- you use the 13 seals to betray the goddess and become all powerful with a harem of all 13 domina's for an evil ending. And #3:- after you get the 13th seal the reaper tells you that the domina's have an offer, give all 13 seals to one of them and she will become the leader of the domina's, make you her right hand man and favourite slave for when she will begin the invasion of the human realm which will happen after she has absorbed the power of the seals for an enslaved world and an MC domintation ending. It's just a thought though, only the developer know how this game will end.
