The Shadow Demon

Chapter 1

Life was not fair.

He learned that at a very young age when he watched his parents get murdered right in front of his eyes.

To survive in this world, one had to be strong and fight. Everyone needs to make their own path in life and travel along it. There is no other way to survive. If one was not strong, they would find themselves dead early on because there will not always be someone there to protect them.

At just seven years old he learned this when he became an orphan out of nowhere.

As a child he was a crybaby and no-good at anything. He would always mess everything up and had somewhat bad grades. The other kids would tease him because of this. He never fought and took everything that was thrown at him. The idea of fighting scared him because he feared pain. In fact, he feared a lot as a child.

But then his parents were killed in front of him, and that was when reality set in. If he wanted to survive, he would have to rely solely on himself, and at his present state that would be impossible. So he decided to change.

It was hard. It was long. There was a lot of work to be done, but he managed to do it.

No longer did he cry like a baby. He toughened up by learning how to fight and learned to evade. There was so much he learned, had to learn if he wanted to survive. Without his parents he had to learn to survive. Without his parents he had to find a way to support himself.

That is when thieving came to him.

At just twelve years old, he became a thief. Now, he had nothing he wanted to steal. There was no way he could steal money, which was all he needed, because he knew it would somehow be traced back to him. So that is why he became a thief for hire. Anyone could call him up to hire him for a job, but that didn't mean he accepted every single job. He only took jobs that he deemed wasn't going to hurt innocent people. He was a thief, not a killer, which meant he wasn't going to steal something for someone that would lead to chaos and hell.

At thirteen, he was the most famous thief in the world.

Because he was such a famous thief and he had no desire to be arrested, he never showed his face to anyone. There was a phone number to contact him. It was untraceable and constantly changed. This phone number was only available to those in the underground world. It worked especially well since most of his dealings were with the Mafia, and almost always, he was tasked with stealing from other Mafiosi, and there was no way anyone in the Mafia would ask the police for help. If they ever needed something from him, they would have to call that number because there are never any house calls.

Because of his great thievery skills and the fact that no one has ever seen his face, they call him The Shadow Demon. He wasn't a real fan of the name since he didn't consider himself a demon. In fact, he thought he was really nice when he considers the type of world he found himself involved in. Maybe he was too nice for this world, but it couldn't be helped. They needed something to call him by, and since he refused to provide them with anything, they chose his name for them.

He supposed it came from the fact that he worked in the shadows and never showed his face to anyone, unless it was with who he actually was. And the demon part? Well, that was entirely not his fault! Nope, he decided to blame it all on one of the Famiglias he was stealing from. They were strong and caught up with him. They attacked him, but he wasn't so easily defeated.

Actually, he wasn't defeated by them, but it wasn't easy to win.

Granted, in this world, they fought with box weapons and flames. And he only had one box weapon and didn't have a powerful ring that could handle his flames so he had to use his box weapon sparingly. He also had to spend time collecting rings for himself. So that would put him at a disadvantage, though he rather that then having people find out what flame he had. Because of that, he chose not to fight with his flame often which is why he learned to be stealthy and try to escape unnoticed.

When that approach doesn't work, there was always his dying will mode, but he preferred to not use that. It was reliable and he trains in it to work on some techniques, but he prefers people not to know about it. It was his trump card for when the time calls for it.

Besides that, he only recently learned how to access dying will mode when he was thirteen. It took a while to get complete control over it and be able to stay in it for extended periods of time.

And now at fifteen, he found himself to be powerful, but he was not so arrogant as to think that he was invincible. He knew there were others out there with dying will flames. There would always be someone stronger out there that was waiting. He wouldn't arrogantly think he could beat everyone. That was a great way to end up getting killed!
