So this is a thought I've had in my head for a while. It's a unique take on a underused character in the series. May expand on it once I get down a decent plot line for it to follow. So far, I've gotten to where the story meets up with somewhat canonical events like the Great War. Will need to do more pondering to further the story's progression and how I want events to play out. Until then, I hope you enjoy this positively saddening chapter.

Samael's POV

How long has it been since I've been here. I can barely remember my life before. Now, All I feel is pain, sadness, anger, resentment, jealousy, suffering. What did I do to deserve this. I did what was asked of me. I followed what I was asked because I wished to know what it was like to have someone to talk to.

All I remember from it is when I taught the little ones running around. Even though I wore a disguise to increase their loyalty to their father, I still hoped and wished they would come to love me as they had also loved my brother. I was jealous of him. He had children who loved him and everything while he made it so they wouldn't even acknowledge me when I pass them by.

They were the golden children who had everything they could ever want. A loving family. A warm home. A person who loves them. Even if they can't recognize me in my natural form because of the disguise. I still felt my heart break whenever I would be ignored and shunned by them when it was just the other day they would be saying that they love me to my disguise.

Even if they hated me, I still tried to help them even in my normal form. Even if I was shunned and ignored, I still tried to make them happy in hopes that they may acknowledge me, even against their Father's orders.

I wasn't given a name until after my banishment, unlike the others who were named as soon as they came into being. While they were happy and frolicked amongst each other, I was alone and working to keep their home in order. I was never accepted. I was the black sheep of the family, literally. While they all had their innocence and ignorance, represented by their bright white wings keeping them aloft in the heavens; all I had were those dark black wings.

When I first came to be, I looked to the face of my brother, who looked at me with hatred, anger and revulsion. And when he saw my wings, in a fit of rage, he ripped them from my back, my first feeling since coming into being was pain. I watched as he tore them out, for a reason I don't know, and burned them. Then he told me what I was. A mistake, a tainted being, someone who doesn't deserve to live. Someone who doesn't deserve happiness. I would be a tool for him.

I didn't know what to think. I only wished to know what I did that wronged him. And he replied with "your entire existence is what wrongs me". And as such, he cast me from his grace until he needed me for a task. And as such, I explored the world below, learning new things and experiencing many hardships. And from those hardships, I learned, adapted, and grew. The wounds I had healed, but the wing that I have now are a mockery of how they once were. Before, their forms were beautiful, but now, they are twisted and ugly. I knew that these wings would never be the same as before.

And then came a time when he sent a message, telling me I am needed for a task. When we met again, he took a look at my new wings and gave them a disdainful glance and me a sneer. before telling me what he had called me for. I learned that he had created children, the Angels. And that they would need a teacher. He made me their teacher, in a disguise of his form. And told me to tell them that they were to never approach or acknowledge the one with black wings.

I was forced to tell them to never talk or acknowledge me. It really hurt to say that since I was lonely with no one to talk to. And it had been like that ever since until one day where my brother tried creating a new race and named them humans. He had left them to their own devices and was shocked to learn that they did things without him having to guide them. When I told my brother that, he seemed ecstatic, wanting to see them evolve more. So, he told me to come up with a way for them to learn and grow. When I suggested a few of them eating from the Tree of Like and Wisdom. My brother acquiesced and bid me to get the first two, a male and female to eat the fruits. And as such they were named Adam and Eve. I brought them to the Garden of Eden and told Eve to eat the fruit.

And so they did, and grew knowledgeable. I sent them back down to teach the others and grow as a species. It was around this time that my brother accused me of treachery and sentenced me to perdition. To add insult to injury, he twisted my being, making me half-dragon and carved runes into my skin to curse me for all of time. Then he crucified me and nailed metal stakes through me, then covered my eyes and bounded my limbs with bindings with runes to entrap me in my own mind. And he threw me from the light.

And now here I am. Suffering unending pain and torment as it feels as if my very being is killing itself. Being used as a tool for other's gains. I waited for a time when I am free of this pain.

I remember a time when I was taken out and used to consume some dragon, before they bisected my stomach to free the being that came to be from within me. Then I was sent back down under, to wait in agony as I attempt to focus what little energy I was able to use to heal my stomach.

I don't know how long I had been here, but all I know is that the world has been changing since I was trapped. I can feel fluctuations of power every now and then. And now was one such time. Only it seemed to be looking for something. And when I felt it wash over me, I felt all the blood in me chill as it approached. I waited wondering what it was that had sought me out. I could feel the madness and power radiating from the being.

Soon, it stood before me, before it spoke.

"Serve me, and I will free you."

I didn't know what it wanted with someone like me. All I knew is that if I didn't, it would kill me. Maybe I should decline, then I would be free from suffering. But... I still want to know what it felt like to live. To be happy. To be loved. To be cared for. I pondered my words for a moment before getting my body under control to reply.

"I accept."

Next thing I know, the stakes are being pulled out of me and I am down from my cross, into the vat of blood under me. I tried to open my eyes to see my savior, but my vision had failed me. So, I attempted to rise on my feet, only to fall. I had never used these new limbs with my lower body as a dragon so I could not. The being watched on as I attempted to move.

"Seems you are weakened from you imprisonment, like me. Well, that can be rectified. But first, to get rid of those ugly wings that show who you once were."

I felt a scorching heat on my back as I felt the feathers turn to ashes and the bones of my wings blacken then harden in my blood on the floor. I attempted to scream out in agony, but a tail intercepted my mouth, blood flowing into my mouth as I swallowed. The taste reminded me of the sickly sweet smell of decay. The blood changed me once again, twisting my body as I felt my lower body return to normal, only stronger than ever, as well as the rest of my body. The pain that haunted me for who knows how long now only felt like acidic fire in my veins.

After a while, my vision returned, and I looked up to see who my savior is. And I was met with the sight of a monster. A titanic being in size and power. It smiled down at me sweetly, all seven pairs of eyes glinting ominously in the dark.

"My name is Trihexa, and you are mine now."

So that was the first chapter. Hope you liked it. As of this moment, the things taking place are directly after Trihexa was freed from its seal. This story will be slightly AU, so the story will not follow the events in the light novel thoroughly. There may be some similarities such as certain events, but most of it will be different with a different ending.

Also, I will probably borrow some things from other fandoms like the Fate series, but not a lot. I will also be referencing different things from other fandoms if they'll help show what I'm trying to convey, for example how someone's clothing looks like or weapon.

I can think of at least one character who will be a love interest and they will be from the Fate series, but not a popular one. Others for the harem will be up in the air. Most likely none of the canon harem(anyone in the ORC) will be allowed aside from maybe Rossweise. Depends on what I'm feeling. That does not mean that they can't be friends with Samael. Also there will be some gender-bending of some characters. I can think of at least two at the top of my head.

UPDATE: Decided to forgo the idea of Samael taking Issei's name and personality. Now the story is strictly Samael. For anyone reading interested in the idea of him becoming Issei in later chapters, I'm sorry. You can drop the story if you want. If you want to have a quick summary of what I intended to do with the whole 'Samael taking Issei's name', PM me and I'll send you a quick overview. Once again, sorry if you're disappointed. Decided it would make a better story to rather have Issei as a goal to strive for than to try to replicate.
