Manor Maid Man

You are a lucky young man who has just been gifted a luxurious mansion! Not only that, the mansion is staffed with beautiful girls of different humanoid species, which are very rare, and they're all completely obedient to their master! However, there's something you weren't told. You are not the true master. Only the true master of the mansion can possess it. Anyone else who takes possession of the mansion will turn into a maid within a week. Your transformation into a catgirl has already begun. If you want to remain human, male, and free, you need to solve the puzzle of the mansion and become the true master within a week! Otherwise, you'll serve as a catgirl maid for the rest of your life! If the number of maids in the mansion exceeds two dozen and there is no master, some of the maids will have to leave. Whatever place they choose to stay in will become a new magical mansion with similar rules and its own puzzle.
