Simon "Ghost" Riley. A good soldier. But even he was on the edge of dying before. A few years ago, at the beginning of his career as a soldier, he was dead for a couple minutes before he was brought back to life. Not a very nice memory. But after that day, he somehow always felt watched. He never believed in hell or heaven. But when he saw the person... or rather thing that seemed to stick to him since that day... he started to believe. A demon was bonded to him now. Just on earth to... protect him? Well, he didn't really now, and neither did the demon. But since then, the demon started to help him whenever he asked. In missions or not. The demon was always close, ready to help. He got used to it rather quickly.

Now, a few years later, he was on a tough mission. He got separated from his team in the enemy's territory.
