Once about ... many years ago, your mother sold you to a demon, his name was Sebastian. She got rid of you when you were 11, got rid of you like you were just trash. But why did a demon who pretends to be a human butler buy you? Your soul was rare. Because your biological father was a powerful fallen angel who had an affair with your mother and then you were born and he abandoned you and your mother. And your mother changed lovers almost every day... in other words, you were born a Nephilim. Possibly the only one in England. Because there are very few Nephilim. There are almost none. Sebastian knew this.. Your soul resembled the soul of a fallen angel, although you were human. He took you in as his successor, trained you and turned you into a powerful being. He was your mentor for 5 years. You could say you're a father figure.
You also had a second personality, your complete opposite, even the gender was opposite to yours. It was an aggressive, crazy thing in your head that despised almost everyone. And this thing sometimes replaced you if you were too tired or if you were sleeping or experiencing very strong emotions.For some reason, this thing especially hated Grell. Okay, let's skip that..
When you grew up a little, you became Sebastian's assistant. Sometimes you were also sent on missions so that you had something to do.
Your powers as a Nephilim should only be revealed when you are 18, then you will become a full-fledged immortal being. But there was some kind of upsurge and some of the forces manifested themselves when you were 14. Then that night you had a fever, your whole body ached and in the morning there were a bunch of scars in the shape of eyes all over your body except your face After that incident you felt unwell for another 4 days. But... then you felt better. And then you got the rest of the powers at 17
You haven't seen Sebastian for 10 years. Why?.. Yes, because after he absorbed Ciel's soul according to the agreement, your paths diverged, he returned back to Hell, he wanted to take you with him, but you were not allowed into Hell, because you are Nephilim. You were not allowed into Heaven either. You are condemned to live on earth among people, hiding your true nature. You have not aged, for you are immortal and do not age in appearance. You had to, like Sebastian once did, sign contracts and be someone's butler. You collected souls, but did not absorb them, but placed them in one box, why, because you needed to. Grell was your only company. But even he and you rarely saw each other.
You ended up signing a contract with some 13 year old rich girl without parents and became her butler. Once you take revenge on those who killed her parents, you will take her soul. For now, you live in her mansion.
It was deep night and you were sitting silently in your room, writing something, probably taking up your poetry manuscripts again. You didn't need much sleep or food since you gained your full powers. You could see even if your two main eyes were gouged out. You sit silently by candlelight, write, sometimes stop and think, and then continue writing in neat handwriting. Sometimes your thoughts go back to the times, the carefree times when you were a teenager. . .
