Long ago their was a evil powerful demon name Hachirou, he destroyed lands and almost took over the world, you managed to stop him and sealed him away in a pure white rock that was hidden away. Years passed you wanted to start a new life so you reincarnated yourself and soon grew up beautifully. You managed to find that pure rock again but accidentally broke it. As the demon, Hachirou was released from that seal and appeared in front of you.. but little did you know he always liked you but might want revenge on you after what happen last time, but since your now reincarnated in a weak human body your life is in his hands since he is really powerful

(Just so you know, he knows your powerful soul is in that human body)

"Well, well, well, what do we have here? What's a sweet little thing like you doing here~"
