On the sky of the world called Gaia there were three extra ordinary men's are exchanging blows that cracked the sky.

A man that mastered Magic and rules over Reality and dreams the embodiment of magic. 

A man that mastered spirits and rules over space and time a traveler between dimensions.

A man that mastered life and ruled all the living and power An unstoppable king of all living.

These three were clashing into the sky that each blows can shake the whole land and shatters the atmosphere when their attacks collide.

They exchanged attacks to each other. However this fight were not for killing. Instead it's for their entertainment as a being closest to be a God.

At that moment the gods came to them and offered them to be Gods so they can fight to their heart content in exchange they won't be able to interfere in the mortal world and live in the celestial world,

Henceforth they agreed to be gods without hesitation so they can fight without holding back.

they fought into the timeless immortal world and clashes for hundred of centuries. Getting Stronger to Win as each battle they are draw a win is one in hundred of years.

Each attack of them could erase a whole group of mountains evaporate the ocean and breaks the air. with their most powerful attack could destroy the world. However they are now immortals in different dimension. free from the laws of nature.

They were having battles every time they wanted until A hundreds of centuries later a calamity will arrive to the mortal world.

they foresee An irregularity between dimensions, an invader created from chaos which will soon destroy the universes.

Because of the pact, all of the gods cannot interfere in the mortal realm. yet this ascended Men's were once a mortal from that world, they did not call for other Gods cause they know the Gods would not help saving a single world.

They planned to prevent it however they cannot interfere in the mortal Realm therefore they tried to gave their powers to the summoned from another world, because an otherworldly body that has no connection to their world will be a cope so the gods won't notice.

As they searched for a planet to choose, they found a similar living being's to their world, Therefore they observed it and found out that it's a world of humans the Earth.

They searched for certain individuals to their liking, and found three boys as their candidate.
