The Mastermind Is My Housekeeper

If you could get your dream house for a bargain under the sole condition that you keep it spotless, would you sign the deed? I sure did! I didn't expect it to come with a clean-freak ghost, but I figured I could just hire house staff. Except that's when the problems started... Why did a revolutionary leader, the master of the Magic Tower, a swordmaster, and a literal demon answer my job post?! I do need the extra pairs of hands, though... Oh well, what's the worst that could happen?
