I don't really get how the adventurers fit into the picture.
What stops the wolves and foxes from killing or getting killed by adventurers?
What's the plan with the upper floor settlements like the succubi, elven and vampire ones? Adventurers will need to pass through but the people living there are more or less MC's subordinates and it's bound to cause conflict. It has been months since they opened the tower but this has been completely overlooked.
