In a forest where no light seems to penetrate, a US Commander and his armed forces were watching a man who sat in a chair as calm as the breeze in the wind. This individual was not bound or chained because no prison could hold him.
A fighting demon, the most feared fighter in the world. Most of the armed forces were trembling as they watched the fighting demon who sat calmly in the chair that he grabbed from somewhere.
"What do you want, fighting demon?" asked the commander signaling his troops to not fire.
A smile as wide as a crescent spawned on the fighting demon's face, the commander widened his eyes and signaled for the troops to fire.
Sounds of machine gun fire went off until there were no rounds left in anyone's guns. A giant smoke screen was in front of everyone until it was blown away by some cliche wind. The commander and everyone else guessed it.
The fighting demon was riddled with bullet holes and yet, his smile remained. "RUN!" yelled the commander as he threw away his gun he saw the fighting demon begin to regenerate.
Flashback:
The fighting demon was a regular human who happened to be kidnapped and experimented on. They gave him the X-Gene treatment, the fighting demon was never the same after it. He gained regeneration at an insane level but at the cost of his sanity.
He endured so much and finally broke out of the facility after learning how to control his body with 100% of his brain. He just punched the glass tube he was in, even if he broke his whole hand or there was glass in his hands.
He regenerated and went on a killing spree, after that, he made a name for himself on the dark web and underground fighting arenas.
The reason the fighting demon was here, in this case, was because he was bored. He had too much money after stealing everything, so he just wanted to visit America and play with them for a bit.
Forgot to mention, that the fighting demon is Mongolian and 6'2.
Back to the present:
Stretching as the bullet holes closed up, he stepped on the ground 20 times and used Soru...
All the commander heard was screaming and silence one after another as his old bones croaked. Tripping, the commander braced for impact and fell onto the ground as he kept hearing death around him.
Suddenly, the voices stopped, and the commander was shocked and scared. Then, a horrible sound permeated the forest, footsteps, slowly approaching him from the direction of the death trap.
Slowly turning his body, he faced the monster in front of him. A bloody man who wore nothing but wolf skin covering his lower half as his chest was exposed. His eyes filled with joy and enjoyment as he witnessed the commander piss his pants.
The fighting demon shook his head and sighed, "You are no fun, I thought you guys would have some type of fun here, but there are only some weaklings."
"Haha! You fell for it, stupid."
"Huh?" The fighting demon then saw the commander slowly take out a button. "You have a button? Wow, so strong."
"Let me show you," said the commander as he smirked. Pushing the button, a nuclear alarm blared all over the forest.
"Self Nuke in 3..."
"This...was a f*cking trap this whole tim-"
*BOOM*
The end of the fighting demon was so simple, all because he was bored.
In an alternate universe...
"I don't like you, Wu, how many times have I told you that," said Kushina face palming. This was the 5th time Wu Jin had asked this question to her.
"But..."
Kushina hugged him, "Even if I don't like you, I am still your friend, okay?"
Wu Jin, at this moment, felt the biggest heartbreak in the world again. Reluctantly agreeing, Wu said, "O-Okay..."
Releasing the hug, Kushina patted Wu on the shoulder and smiled brightly, "Don't worry Wu, if anyone dares to bully you, I will teach them a lesson, okay?"
Wu looked at the only sunlight in his world and wondered, how did he get so lucky. "I...okay, thanks," said Wu looking down sadly.
Kushina sighed and patted Wu's fuzzy black hair, "Cheer up, we are almost ready to enter the Academy."
Wu swatted Kushina's hand away and nodded.
Looking at the sky, Kushina said, "Wu, it is almost my curfew, so, I am gonna go, okay?"
Wu looked at Kushina's bright blue eyes and felt his heart thump loudly. "See you, tomorrow."
Kushina nodded and waved goodbye as she left.
Suddenly, it started to rain as Wu made his way to his house. An old house near the edge of the village away from most people. Entering the entrance, he looked around and sighed. He used to have a family but during a mission, his mom and dad died protecting The Second Hokage.
Both of his older brothers went into Anbu and died in battle. He only had their memories to accompany him. Striding to the door, he opened it with his key, opening it, a loud creek was heard.
"Maybe I should oil it with animal fat?"
Wu sat on his bed and then...took out his shrine of Kushina including a candle in front of a picture of Kushina. Strands of her hair in a clip, and nail clippings.
Crying, Wu began to break down, "You are mine, nobody can have you, but why do you do this to me, my sweet Kushina?"
Kissing the picture, he showered and went to bed. Without Wu's knowledge, a foreign soul of unknown origin entered his body.
Wu opened his eyes in his mindscape, "Where am I?"
He then saw a big man wearing wolf skin covering his lower half, the big man understood what happened as soon as he saw the young boy with fuzzy black hair. Rushing towards the kid, he began to devour Wu's soul.
Wu tried to run but this unknown man was too strong and ate him whole. "HAHA! It seems I have reincarnated, just like those Isekai novels." Gaining full control of Wu's body, the fighting demon stepped foot in Naruto...
