In the realm of the demons, a place in hell, there was a feud between a sect of demons whom wanted to live a more peaceful life, where violence is only necessary when it is inflicted upon oneself first. As a result, those demons were persecuted by demons and ridiculed. They were given the name; "Kawavil" which translates to "Cowardly Villains" in the language of the demons.

Eventually, a great war begun and the Kawavil, desperate to win, realised they needed to stray from the path of a regular demon, or as they liked to call them; "Follosvin" which translates to "The Foolish Monsters". The result of their conviction to stray from the path of the Follosvin was a 12 class system between the Kawavil. Animals, occupations and mythical creatures each represented different classes; Dragon≥Serpent>Tiger>Hunter>Dino>Giant>Cheetah>Fox>Wolf>Soldier>Elf>Chick. Each class is genetic and you cannot go up or down in these class systems. Dragons and Serpents are the most powerful of these classes, and unfortunately were the rarest. The number of Kawavil soldiers fighting in the battle was 200,000, against an army of 900,000,000,000 Follosvin soldiers, and the population of Dragons was 10, and a mere 7 Serpents. The class system indeed separated the Kawavil from the Follosvin, with the average strength of a Follosvin, whom had no class system being the average strength of an Elf Class Demon, fortunately for the Kawavil, Elf Classes and Chick classes, like Dragons and Serpents were quite the minority, with a majority of them being Solider Classes. However, they were still heavily outnumbered, which led to a battle of 1000 years ending in the defeat of the Kawavil. After the war had ended, in its first battle, the remaining soldiers that still lived after their concession, decided to flee.

The powers of the 10 dragons and 7 serpents were more than enough to be able to open a dimensional gate which allowed all the soldiers to flee the realm of the demons, as well as hell, itself. They found theirselves migrating to the lower world, where they decided, they will find a world with life energy, and not only multiply, but also live in peace. As time passed through their search, they found a galaxy, which radiated an immense amount of life energy, especially in this one rock. They decided to explore the rock, and found themselves already at war with the civilisation whom had already lived on the rock, humans, whom mistook the Kawavil Demons as Alien invaders. However, there was one man, a dragon class at that, by the name Jiuphoros Belios whom managed to take an understanding of the human language, the most popular one, English. He made a peace offering, and assured the humans that they come in peace, and fled from a war which they had suffered a humiliating defeat in. The humans eventually understood, and demons and humans had been co-existing ever since, under the conditions that they stay suppressed in a human form, which they were fine with, which resulted in these demons having a battle mode, and a peace mode. Battle mode being the form they took as demons, peace mode being the form they take as humans to interact with others.

Not Many female Kawavil Demons actually remained, which led demons to form rituals on any humans they may have fell in love with, in which the demon would share his blood with her to make her a demon too, to make procreation for them, still possible. Now, in the year 2035 AD, the population of Kawavil Demons is at an all time high of 3.6 Billion, they blend in perfectly with human traditions and cultures, and even adding their own culture, and live all over the world. Many join militaries, and use battle mode during wars, being very productive as military grade weapons. Of course they only accepted because war and the endless violence that the Follosvin had was far worse.

All demons also have their own special abilities, which they had before the Kawavil rebellion ever became a thing, split into 3 special types: Predator, Prey and PredaPrey. Predator type abilities are more offensive type powers, Prey abilities are more defensive type abilities, and PredaPrey being both offensive and defensive, simultaneously, abilities. These abilities stem from the power that a demon wants, and even the Kawavil now, still have it, but it is commonly used to back up the abilities they are given from their class system, to numb down any side effects, which they realised is what caused huge problems during their Thousand Year battle with the Follosvin.
