Prologue

In this world, there are three glorious realms and on each realms lives different race with distinct features.

The first realm is the paradise called Heaven. The most abundant source of pure light energy and the realm has limitless space like the infinite universe. The Heaven is rule by the mighty sole God. He also created the celestial hierarchy of the Holy Order. From the highest order was the Seraphim the Guardians and to the lowest order of the Angels of Virtue. These celestial beings hold an extraordinary amount of power creating miracles and at the same time calamities to the world.

The second realm is the surface known as Earth. In all the three realms, the Earth is the riches source of diverse energies these are the element of fire, water, nature and wind. Also a vast numbers of races live on Earth. These are the Humans, Elves, Demi-beast, Dwarf and lastly the Magical Beast. However, unlike the three realms, they were all independent; no one ruled over them as a whole instead they were organize by their own leader.

But among them, there is one particular race that is feared. They can be equal in terms of power to the ruler of the first and third realm. These are the powerful Dragons, few in numbers yet their strength can shake both the Heaven and Hell.

And lastly is the realm of Hell the deadly pandemonium. Devoid from anything, has only nothing but dark cold air and their only source of energy is the crimson Darkness of the bloody moon. It is a place where sinister beings reside, the High Demons, the evil spirit Devils and the undead Lich. With a monarchy system, they were ruled by one and only supreme Overlord, the most powerful vicious tyrant who dominate among these vile creatures.

There is only one rule to them. 'Power is Everything' and because of it their greed is bottomless that they eventually wage war against the two realm and their first target was Earth.

The Great War turns the world into chaos. The rage of war tears down the wall that divided the realms. Many had suffered during the time of war but in the end the Overlord failed to conquer the two realm. The ruler of the Heaven obstructed him and at the same time, he underestimated the strength of the Dragons and the influential fragile race, the Humans that helps in uniting the different race.

The war continuous until it lasted over a thousand years. Soon the war ended. It is when the Overlord was defeated but not in the hand of his enemies, instead his own blood descendant had defeated him and after the succession, the new Overlord made truce with the other realms for peace.

The union of Heaven and Earth that resisted the invasion eventually accepted the new Overlord proposal.

In one condition.

All high ranking Demons must sealed there power including the new Overlord.

Of course, the demons refused but the Overlord obliges in sealing her own power for the sake of her wish therefore, her supporters followed her example.

However, some still rebelled against the new Overlord but even if she had sealed her demonic power, she was still able to fight them back.

The Rogue demon that are not in favor for the peace bare hatred toward the new Overlord and the two realms but because of their numbers and the enemy was too great they decided in secretly wait in shadows before taking their revenge.

Afterward the peace between the three realms had finally began and because of the unexpected cooperation from the new Overlord. The union also granted her selfish wish and that is…

"I want to build a school!"
