It starts from a great war that occurred about 500 years ago, between the demon race against the angel race along with its allies. That is the race of humans, dragons, fairies, elves and also other races.
As the powers of the demons are at their peak and begin to destroy the natural order in the world, they all unite against those demons to save the world from destruction.
The 100-year-long war has taken a huge toll and damaged almost all parts of the world.
Until the time of the last war, where the demons had a chance to end the war and take over the world with their power which is currently at its peak.
But before the Demon King took action to attack, it could be known first by one of the four Archangels named Shiel, the leader of the angel race who led the entire army.
With his skill in combat strategy and his keen instincts,
he can know the opportunities and ambitions of the demons.
He realized that with the power of the demons that can now destroy the entire race, and managed to rule the world.
The leaders of various races gathered, including the great goddess Aria who was the great leader of the entire race of angels, they talked about the strategies that would be used in the next war.
"The demons will attack first with their full power, If it happens then it is finished our history and this world," said Shiel firmly.
"Right, I feel that the current strength of the demons is much stronger than before" said one of the leaders of the dragon race.
"Then what are we going to do?" ask a king of the human race.
Shiel seemed silent for a moment while strengthening his mind and heart to make a decision.
"Prepare your entire army! We will attack the demons first, and eliminate them in his own kingdom" Shiel replied loudly.
With strong ambition, the angel race and the rest of the races decided to come directly to the demon kingdom with their full strength, and eliminate the demons in their own kingdom.
The angel race along with the entire army of the other races began to invade the demon kingdom, while the demon races were shocked by what those who dared to directly invade the demon kingdom did.
The demon king who was sitting on the throne with his children, and the 10 strongest demons with them.
Suddenly a demon warrior leader came in and gave the information to the demon lord.
"Pardon the noble demon lord, the angel race along with the other races are directly attacking the demon kingdom with their entire army" said the demon warrior leader.
Hearing the news made those who were there shocked and angry.
"So they prefer to deliver their own lives? Haha, it's better than I have to pick them up," said the Demon Lord haughtily.
"All right, let's greet them" the Demon Lord told his children and the 10 strongest demons.
Immediately they all just went out of the palace and faced the entire army of angels and other races.
Finally the great war was fought, the war was so fierce with their full strength.
But after such a powerful attack, the angel race and the others were able to break through the defensive lines of the demons.
Until the entire army of the goddess Aria was faced with the demon king and the demon princes named Zelios, Azel, Diablo, and Astora.
They also fought each other with their enormous strength, but the Supreme Goddess Aria and the Demon Lord Satan had yet to bring out their full strength.
A very fierce fight ensued between Arch angel Shiel with the power of his sun, against one of the demon princes named Zelios with the power of his great sin that is Sin of Warth or Sin of anger.
Despite his full strength, Zelios has not been able to bring out the true power of the Sin of Warth, and that has cornered him.
His younger brother named Azel realized that, but he could not help him because the Arch Angel he was fighting back then was very strong.
Zelios ran out of power and began to spiral out of control, consumed by his anger and unable to control the power of his own Sin of Warth.
Meanwhile, Shiel, who realized it, immediately pulled out a ball of sun that was so big, bigger and hotter than he used to make.
"Go back into the holy fire!" shiel said with all his strength.
Then Shiel threw the sun ball right at Zelios, the attack was the ultimate attack from Shiel who used a lot of magic power and made him limp.
While Zelios is out of control, trying to stop the attack.
But the attack was too strong for Zelios, he growled in pain with his body gradually consumed by the sunball.
"SISTER!" Azel called out to his brother loudly, trying to resuscitate him.
But it did not work to resuscitate him, Azel frantically tried to go save his brother, but he was constantly confronted by the Arch Angel who became his opponent.
The other demon princes were also unable to save Zelios, because the resistance Arch angel gave them was so strong.
Likewise with the Demon King Satan who is dealing with the goddess Aria.
Zelios was still trying to resist the attack with all her strength until she shouted out loudly, but it was also a waste, the sunball was getting bigger as Zelios' body was consumed by it.
Finally, all the demon races had to accept that Zelios the demon prince as well as the power holder of Sin of Warth had to be killed on the battlefield.
Since then, time has continued to go on. The power of Sin of Warth disappeared along with Zelios' death.
The great war that almost destroyed the world ended mysteriously, but that does not mean it is over.
The Demon King disappeared to recover his strength back with a very long sleep.
The empty throne was filled by the eldest son of the Demon King, Astora, along with his two sisters Diablo, and Azel, they guarded the integrity of the kingdom and the army of the demon race.
More than 500 years have passed, but wars between races continue.
Starting from the rise of the vampire race that broke away from the demon race and established many kingdoms, also the angel race that does not want any dark power to rule freely.
Once, a dispute between the human race and the vampire race ensues, humanity begins a war with one of the Vampire kingdoms and is aided by the angel races to exterminate all dark forces.
After the destruction of the Vampire kingdom, 20 years passed, and the human kingdom succeeded with the protection provided by the angel race.
Life at that time was quite peaceful than the previous one full of great wars, now life between races began to get its balance back.
At least until the Demon Lord woke up from his long slumber and the resurrection of the demon race after gaining his full strength.
In a human kingdom, there lived a boy named Yuuta Hajime, who could not use his magic power at all.
But when that power rises from within him, he must accept the harsh reality and must leave his homeland.
