1001 Divine Year, Ancient Calendar.
A powerful storm was brewing heaven and earth. Seven Deathly Sins were on the peak of their power. So-called Gods and Humans had joint forces to wipe Underworld clean, under the influence of Sins. A grave mistake.
While the so-called demons and devils wreaked disasters on crust, the real demons and devils were enjoying their lives. Singing, dancing, painting, crafting etc. Everybody was busy, everybody was working hellishly hard, to make their and others life smooth and comfortable. They didn't knew what was going on the crust, and how will that result in their extinction. Supreme Devil Emperor or The Evil himself, was helping souls to cleanse their sins by absorbing them inside his body.
Afterall, it was his duty to remove and harvest sin from souls and sometimes living beings. Just like Death and Life, his elder cousins.
Now one might think, ' What's happening ? '. Well your thinking is true. It isn't Earth 0 or Main Earth on which you all are living, It was Earth 056 the branch of Main Earth on which Death's judgement about to descend. So, what happened next was very simple. But very complicated on cosmic scale.
The Demons and Devils died one after one, the gods and humans were having fun, they didn't knew what will be the consequences after the battle was done. So rythmic. So they fought till end and slayed all the demons. But Supreme Devil Emperor's wrath was awakened, the prisoned the strong Gods. But humans and so-called Gods, called Ciel the Ancient God King.
While this was happening, The Evil sent the real demons and devils to other dimensions. Having seen the fragments of future with his high perception. He died while fighting Ciel and the other gods. To borrow time for his people.
Hence, even after the death of so- called The Evil. Evilness only grew. Then, the judgement day of this planet came. Time was all this, all the time. Hahahaha! Funny right! Well, yes. Time wasn't able to blink it's eyes just like others. Time sent a (The) Dimension Reaper (well it's actually a grim reaper but it's cloths are made of cosmos and dimensions. And they are the beings that originated from The Void, so it's shapeless and formless void's manifestation.)
And then, the planet was doomed by The Judgement of The Death 0. The Death 56 and that whole dimension was doomed by Dimension Reaper. Well, to be exact not everybody was doomed. Ciel and his followers went to heaven (other dimension, to be exact), engeries of that dimension (Qi, ki, mana etc) were spread to other dimensions, Demons and Devils continued to spread from universe to universe, dimensions to dimensions (without creating hovac.) . Souls of that dimension were given Birth, Death and Reincarnation Department (BDRD). But there was one soul missing, that was the soul of The Evil. Dimensional Reaper gave The Evil's soul to Dimensional Death. It gave that to Multiversal Trinity (Equity, Necessity, Impartiality (and Consequences))
Trinity gave it to his superiors and atlast it is in possession of Time. Now I, Time of 10 Omniverses as the Head of ## Sector of ## floor, will take the test of The Evil himself. How much fun would it be?
