Apocalypse: Transmigrated with an Overlord System - Chapter 1 - 0: What the Fu*k ?

All I know is this is just wrong. I was just reading the latest chapter of One Piece in my computer. And an annoying survey popped up asking me if I want to play One Piece new beginning. Thinking nothing of it I said yes.And selected ‘Realistic’ difficulty.There was a game loading screen. Loading gibberish, and warning me that the world has a lot of surprises in store for me. Not all things are same, because I had to choose the ‘developer’s time-line’.And then telling me to brace for Character Synchronization. And before I knew it, I was no longer your average Joe. And this wasn’t earth either… no this was One Piece.And, I was Monkey D. Luffy. The future King of pirates.I mean what could go wrong? If Luffy could do it, so could I.But this wasn’t the same One piece world I remember. Some changes are small like Kuina being Zoro’s rival… who’s alive.While others were huge. Like… did you know, Whitebeard had an actual beard?! Man looked like Santa Claus on steroids. Jaked and shit!Just what did I get myself into?But does it matter?No.Because I’m going to have the time of my life. This was going to be one heck of an adventure.

Joseph Knox, one of the most prolific and well-known serial killers on the planet.A person considered so demented and manic that even trying to reason with him was believed to be a waste of time. A man so far gone that he seemingly didn't deserve any pity even on his deathbed.So why? Why would a man like him receive a second chance? And why did the world around him seem so familiar?Disclaimer: AU when it comes to some parts of Madara's plan(I'll try to make it make sense at least), and aliens don't exist in this world

“Compared to our time, the current generation just aren’t as reliable” they said, “Still, isn’t he the son of the Hero?” How annoying.

It’s been over ten years since the battle between mankind and the demons ended. The children of the heroes who saved the world are all grown up.

One of them, Earth, was a talented man, and everyone expected him to succeed his father as a warrior and defend his country, but Earth was always wary of his father’s title.

One day, Earth is shocked to find his father’s sword, which was used to overthrow the Demon King, sealed in his family’s mansion.

Because trapped within was the ghost of the Great Demon King who was unable to pass on and continued to roam the world.

For some reason, only he could see the spirit of the Demon King, and the Demon King possessed him through the sword.

Every day, forced to coexist with the spirit of the Demon King, they live a strange shared life, when the Demon King whispers to Earth on a whim.

“I have a grudge against your father. If you want to get back at your father and the world, I’ll train you. I’m free.”

Earth receives special personal guidance from the Demon King just to get back at his parents and the world.

Then, in the coming days. The hero’s parents, the heroes of the past, the first love, the princess childhood friend, the geniuses of the era, and the world will tremble.
