A long time ago, Zeus, god of thunder, was up to his old tricks, basically screwing around with anything that moves.
However, doing this to a female prostitute,would bring out a change in the world by giving birth to the two shigaraki twins.
The gods didn't realize this until it was too late, so, to appease his wife hera, no god was allowed to go to earth again unless it was as an extreme punishment.
That's where our story begins.
Unknown to the mortals, there is a goddess that was always a problem for the other deities, Skoria, goddess of waste, a woman so dirty not even Zeus would put his dick in her.
After not being allowed on earth, she began putting her things in the Olympus, and they were so many the place began to reek.
So,they unanimously decided to kick her off Olympus until she learned to be more organized.
What no one knew was that this would change the history of humanity.
