The Demon King's Favorite

I was beyond furious. How dare this happen in my kingdom. "Your Majesty, it's true we fought and yes, I did threaten to get back at her but I wasn't the one who attacked her and took her horns" the blonde haired witch pleaded. I was in a dilemma. The demon whose horn had been sawed off was seething and would not be patronized. "Where were you when it happened yesterday?" I asked the kneeling woman. "I-I was in my home sick, your Majesty" "And do you have anyone to confirm it?" "No, I'm a widow and I live at the outskirt of the three kingdoms" "We'll look into this further. I'm tired now, we'll continue tomorrow after further investigation. For now there's nothing incriminating against her" I said taking my leave of the throne room. "She lies my Queen! I could have sworn I smelt her before I got knocked unconscious" the female demon whose horns were severed spat out. "You would watch your manners in my court" I hissed to the demon whose name was Menilia. "My apologises my Queen" Giving him a deathly stare, I head to my chambers where the maids were already waiting for me with a hot bath. *** The old witch was found dead in her home the next day and her fellow witches were crying for blood and demanding justice. Never had this happened in my twenty years of ruling the two kingdoms. I couldn't give them the demon even if she was guilty of killing her and let them take justice into their own hands. I passed my judgement and Menilis was beheaded for killing the witch and I thought it was over there. A year later, the female demon's population had reduced to more than half of what it once was . Female demons died during childbirth and gave birth to stillborns. A knock on my chamber's door jolted me out of my thoughts. "Come in" "My Queen" Agyris my second in command bowed in greeting. "What brought you here? You can sit" "I have news" "Well...then tell me" "Not news actually, more like rumors. Word on the street is that it was the witches. They cursed us" Sighing, "We are out of options, bring the leader of the coven to me now. I don't care if you have to drag her all the way here" "Yes, your Majesty" Few minutes later, she stood in front of me in the throne room. "I know what you want to ask. Yes I did it" she says smirking with a crazy glint in her eyes. "You admit to cursing us?" I ask incredulously, shocked at the audacity. "Yes. We've been oppressed enough. You limit the use of our powers. Our children have grown weak, they have little or no knowledge of the old ways. They only knew useless spells. You made them weak with your rules. The previous King wouldn't have accepted this" "The previous King was a tyrant and a witch. He became mad after the loss of his only child and fell into dark magic! Take her to the dungeons!" "There's no need" she said spitting blood and clutching her stomach. "I'm dying anyway. The curse is going to die with me and so are all your females" She fell on the floor laughing till she stopped breathing.  It was then I knew she killed herself to be a matyr to the witches. The witches started revolting and I declared war on all witches. By the time, we won the war, there were only few witches left and they pledge their loyalty to us in exchange for their lives but the problem of infertility couldn't still be solved. So I did the only thing I could to save my species from extinction. We went to the human world.
