Theodore smirked at the succubus who was begging for his mercy and said in a devilish tone, "Don't be afraid dear, I won't kill you. But if you don't do as I say, then I just might make everyone forget you by making you disappear from the face of Hell."
The succubus didn't want to disappear from existence. She wanted to live for as long as she could. That was the sole reason why she went to Earth in the first place. And now that the Devil Prince was threatening to wipe her whole existence, she began to wail like a little baby whose toy was snatched away from them.
She joined her hands together and pleaded to the Devil Prince while crying her eyes out, "I will do anything that you ask, Your Highness. But please, don't kill me."
