1 The day it all began

Year – 9478

Human civilization was standing at the peak of development, even taking a holiday to the Moon was not a hard thing to get. People have everything they can ask for, no longer did they have to move from their couch to complete their day everything they desire will be their just press a button and you got it. You can say that it was a lifestyle none of us wants to give up for anything in return.

But not everything stays as it is, a very unique thing happened people with a unique power that was only heard in frictional started to appear in real life, which was named 'QUIRKS' by the people of the world.

The first quirk which appeared was a bay in North America he had an offensive type quirk and one day when he was in school his quirk appeared and all the children and the teacher died. The American government tried to hide it from the rest of the world but nothing can be hidden from the internet. The news spread like wildfire on the internet but it was only considered fake, but slowly news like this came from all over the world and this news was no longer considered something fake that was just circulated by some crack head.

Scientist all over the globe tries to explain what was happening but none of them can find anything, they may not be able to find what was happening but finding the use of even the most useless thing was the specialty of people of those ages. Peoples with quirks started to disappear and the most interesting thing was that children with quirks were nothing more than things to sell and to buy them use them as you want was the new trend of the underworld.

Slowly the cases of violence, kidnapping, murder, human trafficking, discrimination, and whatnot people with quirks were being treated like monsters riots happening on a national scale and this was the story of all the nations of the world. The government tried everything separating the people with quirks, some of them thought that if it is any kind of mutation so if its source could be found maybe something could be done, brutal experiments were performed and every possible kind of thing was tried no matter how ridiculous it may sound or no matter how inhumane it was.

A new international committee was formed which consist of the heads of all the states, many nations wanted to accept these peoples with quirks but many didn't want and slowly the tension between these nations increased and the world separated into two factions every possible idea was tried but nothing worked. Young children which were showing signs of a quirk were being separated from the society along with their whole blood-related relatives because many people thought that it may be blood contagious. Mass genocides were the last option that they have but soon they run out of all the other ideas so that is exactly what they did and this was the start of the demise of their perfectly crafted world that can withstand even the strongest disasters was crumbling. A man may not be able to defeat an elephant but an ant can.

Somewhere between Year – 10048_10060

Nobody remembered who strike first but it was a spark they all have been waiting for, you can say that it was a war for people for quirks to give them their rights. It was just used as a cover to annihilate others for more control of everything they can get their hands on.

Billions over Billions of people died just in the crossfire of powerful nations. No information was there about who was working with who or what the other was after, at the first stage of the war the communication was targeted. Everything happened so fast that nobody would have expected that you wake up from your sleep and seeing the whole city burning up and littered with corpses.

Japan was kind of a major eyesore for more than half of the world, despite being small compared to the major powers of the world it had support and it had tech, but backstabbing and circumstances was a huge blow to Japan and it had a great hit which knocked it out of the war.

The war continued for a few centuries, super-powerful weapons against super-powerful defenses the people were suffering and generations later the only reason left to fight this war was to win, but something unexpected happened that none of them expected.

A new kind of energy was discovered and this was not something good it was something that resulted in the phenomenon knows as dimensional shift. Countless wormhole/portal-like structures opened up in the entire world known as 'Dungeons' and creatures that humans have never seen rampaged throughout the lands killing everything.

This was already bad as it was but a new threat came and people started calling them 'Demons.' Man-eating creatures that ruled the night. They possess superhuman strength, speed, senses, and abilities similar but far more powerful than quirks. Humanity tried its best to fight back as much as they can but when they were near annihilation they realized that alone they may not survive but together they can.

All the rest of the people of the world came together and fight these creatures. As time passed by and after countless sacrifices and efforts the situation was coming in control. The magical beasts, is what they called the creatures that came out of the dungeons were ranged in size and strength and some of them possess certain abilities but can be dealt with, but demons could only be killed with sunlight and this was a huge-huge problem.

So after a decade, a family named Ubuyashiki in Japan founded the 'Demon slayer corps' and gave the world hope of fighting against demons. Slowly the world was stabilizing, but many things were lost the world which was once stood at the peak of development was brought down to the medieval ages. Slowly development of civilization started again and when the whole world was once again connected online it was called 'The starting year-1'

Demons and Magical beast were still present in the world with an extremely high crime rate so to fight them a new concept was bought to the world a concept of 'Hero.' Group of people with quirks formed an organization to help society get better and save people from other who use their quirk for harming others. Everything was back to its order and the new things were finally settled in and things went slow but there was peace and order.

Year after the war 1021

On top, a tall building a boy was crying he was wearing a middle school outfit with red air force sneakers he had green curly hair, and his eye color was also green but his left cornea was red instead of white. A yellow schoolbag was lying next to him with an open chain and the content of the bag was spilled all over the rooftop with some torn-up notebooks.

He was righting something on a piece of paper and his eyes were filled with so many tears that his whole face was covered in tears and his vision was blurry but he didn't mind as he folded the paper and opened his shoes and walked over to the edge of the building put them down with that piece of paper, his phone and whatever money he had with him.

He climbed over the fence and now he was looking at the city below him full of life, people walking on the streets the sound of cars, so much light all far as the eye could see, he was holding the iron bar because the wind was blowing so hard he thought that maybe the wind was encouraging him to jump, but it was cold which help him relax. For a moment he started below him for a while and gathering enough courage in his mind he was ready to jump but in his final moments he wanted to be happy, he doesn't want to leave this wonderful life like this. His life may not be the happiest one but still, even for a second he wanted to smile but even a fake smile refuses to come to his face.

He closed his eyes trying to remember his life in every detail he can, he knew that this is a foolish idea he was searching for happiness but all he would found will be sadness damn well he knew that his life was only filled with pain and misery but still maybe there was something that can make him happy in his final moments, where he was about to commit the sin that not even God will forgive him for, but still everybody deserves a little joy in their life.

As he closes his eyes and his whole life flashed before him.
