Decades ago, the world government set up an ambitious organization of crazy people who were highly skilled at assessment training.
The project is a superhuman project, where the project is used to create various humans who can be used as soldiers for the benefit of the world government.
This idea began to be created because they suffered several defeats after defeat on the part of the Elves and Bestmen.
The project is led by a mad scientist who is crazy about Magic research, with the basis of making grimoires scattered around the world, he began to think of a way to make an invention that was not inferior to the one who could create such a grimoire.
Some of the things the researcher did to get his wish, from taking various corpses from various races to become the object of his research, that he did to achieve what he wanted.
Although not known to the world, the impact of the study still caused a world uproar.
Because there are thousands of children who suddenly disappear for no apparent reason, to cover up such a thing the government is doing all sorts of ways to cover it up, including making some areas in a cementitious so that the attention of the world's population is slightly diverted.
The thousands of children were selected in such a way that they became superior seeds, from the thousand children they managed to get, they almost eliminated half of them, children who did not pass the Selection.
Will soon obtain the memory removal magic, and soon be released in the outside world, they will be lucky enough if they can return to where they came from.
Five hundred children they continued to train, and they used as objects of experimentation. The experiment was aimed at eliminating the function of the Grimoire as the need for witches as a tool to fight and prefer to use their bodies as a catalyst for magic.
What they believe in by using the body as a Magic catalyst, it can make longevity like what happened with the Elves.
Horrible experiments, and training to become a tough soldier that is no less frightening by making one by one the children there fall.
In the facilities they are detained they are simply named Using numbers, the lower the numbers they use As names, the higher the value for the government.
And sometimes the highest name holders get better treatment, so among the children who are there fighting for names has become commonplace.
It seems like the treatment that the children received there did not make them happy at all, but instead grew a seasoning of resistance, one of the people who most often instigated people who were there was the highest rank among the children who were there.
The one called Absolute Zero, to the children who were in the lower classes, to them Zero was a monster they could not defeat.
In various ways he managed to send several messages to the children in this shelter, to devise a plan to escape immediately.
Absolute zero is none other than the young diablo, he wore his fame a to continuously instigate and obtain various information from the various essentials involved in this research.
He slowly began to carry out his plan slowly, with the help of several colleagues who fared the same, using the knowledge they got from this research they managed to trick the researchers and guards.
With one chance, he got all the children there to fight, the plan was executed well, so as not only to escape the research facility that had locked him up for a long time.
After successfully exiting them all decided to take their respective paths including zero, although not knowing what to do, he continued to walk after the wind.
But since he had just come out he was not the least bit careless by accepting the offer of food from the Stranger making him get his first slave Seal.
He was the expert of the experts who had been formed by the world government, if he wanted he could easily release the slave Seal attached to it.
But because he does not know what to do after coming out, some children may still think to look for his parents, but Zero different he from the beginning is just a street child, indeed, who survive by stealing from others.
One of the reasons why he was caught in the organization, at that time he was caught by the store owner, and ended up being sold by the store owner to a slave trader.
And ending up inside the research facility, he casually continued to follow the slave trade, until he got his first master, he was quite unlucky in getting the master, he was quite unlucky in getting the master, so Zero prefers to kill his master.
This becomes a step phenomenon where a slave who has killed his parents, because usually the slave seal that has been installed in his body can make the slave will also die If the master dies.
But to Zero it was common, with the Brief he disappeared the slave seal, the slave seal that was in his body did not disappear forever but only disappeared for a moment, but in that short period of time Zero was able to kill his master easily.
Yet zero continued to make every death of his master like a mere accident, so that after the incident it kept repeating for several times made his famous as a cursed slave.
Until One day, He felt a very terrible Aura come out of a child who was almost the same age as him. HE found the boy very attractive, so he made the child as attractive as possible to him.
And the plan was successful so that during the slave auction that took place in Gowa kingdom, the aak got it young. Because after his name zero is famous as a slave of doom.
No one else wanted to buy it, but after he met the Child, he found that the Child was not interested in him at all.
What is not known turns out from the beginning the child named Aether from the beginning was not interested in him, but he was only interested in the Aura issued, but he was only interested in Aura, but after seeing it directly He found that the aura of zero was no longer of interest to him.
The Aether at that time felt a very intense killing aura, so the initial assumption was an aura from a person who had killed many nyama, the aether initially thought that it was the aura of a swordsman.
But by looking at it directly Aether could find out that zero was open to a swordsman, he immediately lost his interest, and this treatment made Zero even more interested in him.
And Finally Zero finally managed to persuade Aether to become its master, because getting such an offer made Aether not refuse.
“Zero seems like a bad name, from today your name is Diablo, a demon who will continue to be at the top of the food chain.” Said the aether giving a name to his new followers.
That was the beginning of the meeting of the two who in the future would continue to shake the world with his abilities.
