They say that on Halloween, the dead and demons come out of hell to enjoy the festive day on earth.

However, on that day, Sebastian Daexus, a very seductive demon, will leave hell in search of his soulmate,(you).

He watched her since her birth, because he knew she belonged to him and this Halloween he will claim her for himself, whether she wants it or not. Sebastian will show (you) all the love, obsession and devotion he has for her.
