Great Demon King - prologue

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

Broken-hearted and drunk, Yoshida, a 26-years old salaryman, stumbled upon a runaway-from-home high-schooler on his way back from the bar.

“Hey, you. JK.”*

“What the heck are you doing out here. Go home already.”

“Uncle, let me stay at your place for the night.”

“You can do ‘that’ to me if you let me stay.”

“If you meant that as a joke, it’s not funny.”

“I’m not joking. It’s fine by me.”

“Then allow me to tell you that I have no interest in brats.”

“Hmm?”

“Then, just let me stay.”

Notes:

[*] JK is slang for Joushikousei (high school girl)

The old man pointed to the flower-like woman and said, “Call her mother from now on.” He then pointed to a flower-bud-like girl and said, “This is your sister.”

My younger sister was not cute.

She was arrogant, taciturn and weird, but she knew how to please our parents.

She was two-faced and deceitful, but it seemed like she only treated me that way.

I cared for her, tried to please her as much as I can, but she still disliked me.

Until one day, I found out her secret, our relationship began to get a little bit weird…

What would happen in a world governed by the Ascendants, the highest level people in the System, when the System itself resets due to the death of its creator? When the levels, classes, skills, and even Legendary Feats of every user are wiped, and everyone is sent to a new dimension to start all over again? Alexia, on what should’ve just been her very first Dungeon dive in the Royal Dungeon, finds her life, her body, and her entire world changing after the Creator of the System itself forces her to kill him, resetting the System entirely. But after being turned into a quantum reaper and given the powerful quantum element as a ‘prize’ for her Legendary Feat, will she thrive? Or will she fall? What to expect: Quantum Magic using Main Protagonist, Anti-Hero Protagonist, System Reset, Polearm using Protagonist in terms of their weapon, and LitRPG. What not to expect: Magic to follow science and reality based on quantum mechanics. There will be some skills that will have some relation to quantum mechanics in the much later books of the story, but definitely not at the start, and not too deeply related. Do not expect magic to follow laws of science. The world that the main character is in prior to the Reset is not a modern world. It is more similar to a fantasy world with swords and sorcery in terms of the morals and ethics of the people just with modern technology. Furthermore, Alexia is twenty years old. Furthermore, the vast majority of the reviews are out of date due to me editing the story as it goes on.
