Issei: The Noblesse

Prologue

A long time ago, there was a being with the ability to face up to being able to face the most powerful creatures that exist. This being is someone who has even caused fear in the Biblical God. This being was someone who was feared by many people who knew him.

This being was responsible for dictating the fate of many people. Thanks to his legendary power, there were those few who admired him. However, most feared him because of his power. And then the years went by quickly. The being became more and more feared as time progressed.

What most people didn't know was that this being once lived among humans. His name as a human was Hyodou Issei. He adopted the appearance of a young teenager with brown hair and eyes. However, several things led him to become what he was today. Someone who dictated the fate of others of his race. Someone totally unshakable. Someone with legendary power.

And so, he was finally isolated. No one wanted to get close to a creature with the ability to completely destroy them. The being lived isolated in a mansion in a place that was only known by very few people. He just accepted all that and stayed in his castle.

More years passed, and the being remained in its castle. They say he never left that place. However, at a certain time, this being learned that there would be a war between the three main factions. Angels, Fallen Angels and Demons.

Honestly, he didn't care about any of this. However, there was something he did not accept at all. And that was the fact that innocent people were involved in mindless killings. The being greatly admired humans, and his people protected them most of the time.

So, the being did something considered unheard of by many.

He left his castle.

He went straight to the place where the factional war was taking place. When he got there, he witnessed the ridiculous slaughter. He really wanted to do something, but that wasn't his job. He would only interfere if it was absolutely necessary. He had the power to interfere, but it would cost him a lot. So who knows how long he would sleep if he ended up getting into a full-scale fight like the one he was involved in in the past. There was no way he could predict this time. So he just watched everything.

However, something caught the being's attention.

A silver-haired woman in an outfit that resembled a servant. She seemed to be running away from some demons. He remembered that there are demons that are part of the ancient faction of demons. He found this strange. Hadn't they already lost the war against the new demons?

Seeing that the woman was in danger, the being saved her.

After that, she decided to pledge allegiance to her savior. She realized he wasn't one to talk much.

So, as time passed, living in the mansion, now with a new person who acted as his servant, he lived as before. He didn't say much.

After some time, a man with long blond hair seemed to have invaded his castle. Initially his servant was hostile towards him, but his master just raised a hand to her. Afterwards, some of his people came to the castle claiming that a human had entered the castle, but the being just said that he was another servant of his, surprising the man himself and his guards.

After that, the man began to do the same for his maidservant. She took care of cleaning the castle, while he did the food and teas. Over time, the being gained two people living with him.

Although...

In one day, the being had completely disappeared from the map. He disappeared without leaving any traces. It was like he never existed. Only a very few people knew about him, and some even started looking for him. Some after his legendary power, while others just wanted him back, after all he had a great duty.
