So, are there gonna be more interactions with the dead maids besides 'using' them, or is that ending... well, a dead end.
Edit: If you don't have any future plans for this route, might I make a few suggestions if you're open to it? These vary based on how much of a psychopath you want the MC to be.
Since you've already established the existence of magic in this world, I don't think a Necromancy Route would be very far fetched. You could just make the resurrected girls mindless, obedient zombies, but I think it would be far more interesting to have them keep their minds intact and be forced to cope with the fact that their new master is, not just cruel, but also a fucking necromancer.
Alternatively, you could turn the MC into a full on horror antagonist with a "You're My Toys Now" Route. Basically just have the MC play with the girls like dolls, and I mean full on treating them like dolls; dressing them up, doing voices for them, the works.
Either way, I highly suggest making their skin turn blue like the girls from Zombie Land Saga.
Just a few thoughts of mine, thank you for reading <3.
