In the year 2158, World War III was brought to a close. By then, every country had joined the UN, which changed its name to the UEA, the United Earth Association. However, the threat of war always lingered just around the corner, waiting for people to lower their guards before striking again.
It was about that time that some of the most renowned scientists in the world decided to get together. Their goal was simple: create a group of super soldiers to keep the peace in the world. So they set to work creating a serum to make their dreams a reality.
However, this group met quite a setback. In their first test run of the serum, only one of the participants survived the process. Experiment #000, a young 13 year-old boy named Tomoshibi Fujidana.
However, the single success helped scientists learn what was wrong. Of all the participants, only Tomoshibi had been a child. Thus, the theory that only children could survive the process due to their adaptability arose. With this in mind, the scientists gathered the strongest children they could find and performed the same experiment on them, this time with a perfect success.
However, the experiment did have one flaw. Each surviving experiment developed uncanny abilities. Thus, they became known as Demons. The scientists pushed the children to their limits, making sure that nothing would stop the Demons from reaching their full potential. During the process, most of the experiments grew more and more hateful of the outside world, wanting to take it for themselves. And so, one day, those that agreed with the philosophy that they should be in control revolted against the government of the world, attempting to seize control of it from the older and more experienced generation. War had reared its ugly head once again, though it turned out to be a quick one. Because the children had more power than all the armies combined, they seized control relatively easily.
It was during this process that Tomoshibi stood against his fellow experiments, fighting to protect the world's safety. During one particular battle with his brother, who had been included in the experiments, he was lost to the world, disappearing into the abyss. Or so it seemed.
Five years have passed since that time, now known as the 40 Days of Weeping, and the world lies in a state of eternal chaos. But it does have one hope. A young man, 18 years of age, who has no memory of his past, no memory of who he truly is. The only thing he knows is Zero, the number written on his right arm. In full, the tattoo reads Experiment #000. What this means he does not know. But he will have to find out, because if he doesn't, the world may not see another day. If he doesn't, he will die when those that fear him most of all find him. And so begins a new day, one of chaos and destruction, but most importantly, one of hope.
