Universe 3462665###^$%%$#(Mushoko tensei World)

In the vast Multiverse, the Universe 3462665###^$%%$# can be said as a Mid-High World/Universe or at least how it was. Currently, its rank has dropped to Mid-Low World/Universe. How did this Universe drop in Rank? A question no one asks after all how many know about the existence of the Multiverse? How many can travel between worlds/Universes? The majority of People who can travel are at least Galaxy Tier beings and they are strong enough to create their own world so they won't care about a low-rank world such as Universe 3462665###^$%%$#.

This Universe was created by a being called Creator God by the people of this world.

The Creator God, a being at Galaxy Level created this world, he created six dimensions of this universe for different species. They were Dragon World, Demon World, Human World, Beast World, Water World& Sky World. The different species inhabited each world and they were named after the species of the residents of the world.

The Creator God used much of his power in Creating the worlds and his level dropped to a planet-level being, he will be having a huge lifespan and still die like a mortal. His death started disputes between the different races, though there wasn't a war due to each species having a different world their disputes created a rivalry, and to win the rivalry each race needed strong people, Strong people were respected, and soon the feeling of power, respect corrupted the strong people, they started thinking themselves as the rulers, overlords, and superior beings than those who were weaker, a hierarchy of strong prey over weak started and started inner turmoils in the races.

The Creator God had predicted that something like this will definitely happen and so to ensure that each race doesn't become extinct he create Gods who presided over each world.

The Dragon World had Dragon God and the Five Dragon Kings/Generals, Demon World had Demon Gods, the Human World had Human God, Beast World had Beast God, The Water World had Water God and the Sky World had Sky God.

Though the Gods did have disputes they ensured the survival of their own race. Everything was fine or that was how supposed it should have been.

Due to the release of Negative Energy by Humans, a being or Evil entity was born. The Entity usurped the powers of the real Human God and became Human God itself. The being Named himself Hitogami.

The being wanted to destroy the world and get more powerful by the release of the Negative energy that will be caused by the chaos, destruction, and war. However, he wasn't that strong to take on all Gods himself yet during that time so he decided to Manipulate the Strongest God to start a war with all the other Gods.

He manipulated the Dragon God and his five Generals on destroying the Demon World, beast world, sky world & Ocean world. Due to the Negative Energy produced by the massacre and destruction of the world, he became a Constellation-level being. He was now strong enough to take on the Dragon Gods himself so he started a war with them. Dragon God finally realized how Hitogami manipulated them but it was already late, Hitogami has became too strong by that time for them to kill him.

Hitogami killed all four Dragon Generals, Dragon God seeing that he can't kill him teleported his son Orsted to the Human world and used his all powers and life force to trap the Human God in the void a place which even the Creator God feared of. Before his death, he ordered his last serving Dragon King/General, The Demon Dragon God Laplace to find a method to kill Hitogami. Laplace took an oath that he will kill Hitogami or die trying.
