The story is wonderful, and the idea of building a kingdom to support the witches while gaining their power in case of war is interesting. The mystery about the demons is also a nice plot twist.

The story is different from what I usually see and has interesting unexpected plot twists. The addition of the mystery about the mutation inside the MC's body is interesting too. I also like the idea of having wives instead of team members. I feel there is a reason why the author has chosen this route for his story because usually harem novels have dense main characters without an actual story, unlike this story.
