(Narrator's pov)
100 thousand years ago the earth was created by an entity known as The Absolute Being. Then briefly after came the humans who quickly rose to the top of the food chain.
Thousands of years later spatial distortions, forming portals later named gates by the humans, started appearing at random worldwide. Unleashing monsters upon the human race.
Nearly wiping out humanity in only 5 years causing the Absolute Being to take pity upon his creation granting them spiritual cores giving them access to supernatural abilities.
Thanks to these abilities the humans were able to fight back against the monsters leading to a 100 year war where the humans managed to defeat all the monsters residing on earth although the portals showed no signs of stopping.
The humans realizing that they could not continue like this created the adventures guild where brave heroes were paid to kill any monsters exiting the Gates and entering the human realm this marks a new era for humanity known as year 0
-300 YEARS LATER
(Nurse's pov)
"Doctor, unfortunately she didn't make it," is what i said to the doctor after realizing that the woman's heart was no longer beating."What a pity the child will have to be sent to an orphanage", an orphanage? What about his father? Is he dead too? "If you don't mind my asking what about the child's father?" the doctor's expression saddened at the mention of the child's father. "His father was a good man, unfortunately he died 6 months ago, although his body was never found".
"I see well i will call for a carriage right away"
-5 hours later
"So how much longer will it take to get to the orphanage?" I asked the coachman. "Only a few more hours" It's getting cold. I'm worried the children will get sick they're only kids so they're prone to getting sick.
Out of nowhere I heard a wolf howl. Scared, I asked the coachman how common are wolf attacks around these parts of the forest. With a carefree attitude he says "Dont worry ive worked as a coachman for 5 years now and never once have I been attacked by any animal or beast" as soon as he said that his head was ripped out of his body as his blood was sprayed on me and the orphan children.
The baby that lost his mother today while giving birth at the hospital suddenly started giggling as if he enjoyed the gruesome scene in front of him.
"Hehehe that baby sure knows the meaning of the word fun I wonder how he'll react to me killing all of you" I was in shock this giant wolf like man was about to kill all of us. I ran, I didn't care about the kids anymore I dropped the baby and ran as fast as my feet would carry me. Before I knew it I could see my headless body on the ground.
(Demon's pov)
" Serves you right for thinking you could escape from a demon as powerful as I" I was surprised she actually left the kids to fend for themselves, so much for human righteousness.
(Narrator's pov)
In a matter of seconds the demon killed all the orphans except for the newborn baby "Know it's the ba-". The demon's arm was suddenly sliced off and the baby was now in the arms of this old man.
"I've been looking for you Yamato i haven't seen you in nearly 7000 years not since you abandoned us during the war against the gods"
"You sure we've met cause I dont think i've never seen a face as ugly as yours" enraged the demon charged at the elderly man. The old man readied his blade which got engulfed in a black and red aura as the old man struck the demon with his blade ending him in one strike. "Well that's taken care of now what am I gonna do with you little man"
The baby looked at him with a massive smile on his face as if he hadn't just gone through such a trauma inducing event."it must be nice being able to go through life without a care in the world" seeing that the baby seemed to be an orphan the old man decided to take him in and raise him to teach him how to survive in this cruel world where power is everything.
-4 years later
(Yamato's POV)
"!!!COME ON DO 50 MORE LAPS!!!FOR 4 YEAR OLD YOU GET TIRED PRETTY FUCKING FAST."
"Come on gramps give me a break i've been doing 150 laps every day ever since i turned 4, 5 months ago can we please do something else"
"Not until you can manage to do 150 laps in your sleep."
Without any other choice he got to it
-2 years later
"Happy birthday little man now that you've turned 6 is time for me to teach you how to properly swing a sword,here" I threw a wooden sword at him although he wasn't as good as i thought he was at catching looks like i'll have to teach him how to catch with his hands instead of his face."
Damn he's bleeding a bit too much I think i'll give some slack for an hour or two
"Hey go clean that blood off of you we will get started with your training later consider this your birthday present"
-50 minutes later
"Ok times up I practically gave you a whole day of rest know it's time to start training those swords skills"
"!!!HUHHH!!! What nonsense are you spouting old man it's barely been 1 hour at least have the decency to let me rest properly on my birthday"
"Stop acting like a little bitch know get your ass up pick up the damn sword and come get your ass whooped"
(Narrator's pov)
The boy picks up the sword next to him and charges at the old man and proceeds to thrust at him with all his might
The old man dodges effortlessly and smacks him on the head. This went on for hours but all the old man could deduce from this little match is that the boy has a hard ass head.
So for the next few months he taught him how to properly wield a sword
-8 months later
"Wake up little man where going to hunt a bear."
"Gamps I don't think you realize this but, IT'S 3 IN THE MORNING!!!!"
"Of course i know its 3 in the morning where leaving in 4 hours so go warm up in that time, of course by warm up i mean intense training but im sure you deduced that on your own"
-6 hours later
They find the bears footprints and start to follow them
"Gramps my bodies killing me we've been following these footprints for hours and i'm tired could it be that maybe you somehow manage to forget i'm a 6 year old"
"Come on now im too young to have alzheimer of course i know your 6 which is why i'm not going too hard with your training regimen"
"Tks not going too hard on your training regimen he says i'm not buying it"
"Shhh i hear something i think we found our prey"
As they were looking towards the forest where the noise came from a giant bear easily surpassing 9 ft in size while standing appeared in front of the with a bloody mouth
"Think you can take him? You have been training pretty hard"
With a bit of fear in his eyes the boy answered with a yes although not looking too sure about himself.
"Y-yea i think i can take him im sure my training will pay off"
The old man then proceeds to smack his head
"That was a trick question your weak sauce can't beat him no matter how hard you've trained he'll split you in half without even trying, listen if you wanna survive in life you need to know the power difference between you and your opponents and proceed accordingly"
The bear roared at them as he got ready to charge them
"Stand in the back of me little man"
The old man readied his blade and lift it vertically above his head as it got engulfed in a black falme outlined in a red aura
"Demonic slash"
He said before he slashed the air sending a crescent like vertical energy slash at the bear cutting him in half
"!!Whoa!! Gramps since when were you able to do that "
"Hahaha don't worry about small things like what i just did you have way bigger things to worry about,like carrying that bear back home"
"!!!hahahahaha very funny gramps you sure know how to make people laugh come on let's go home"
"What are you talking about i wasn't joking if any thing you should probably start cutting him into pieces you can carry and take them home one by one, if your fast enough you'll be finished before nightfall"
He said while walking away
"!!HEY GRAMPS COME BACK HERE I'M NOT CARRYING THIS GIANT BEAST HOME BY MYSELF GRAAAAAAMPS!!"
He carried the whole bear home piece by piece it took him about 14 hours by the time he was done he was starving,dirty and really tired fainting before reaching his bed
- the next day
"*yawn* dammit i always wake up in the best part,whatever time to make the little man get ready for training"
He gets up and and starts heading outside in order to get some fresh air when he hears the noise of a sword getting swung outside so he decides to take a look before heading out himself
"Hmm the little man seems to have already started training glad to know he's finally started to enjoy training as much as i do"
"Lets see if i remember correctly he lifted his blade above his head like this and then he…" '!!WAIT WHAT'S HE?!!'
He then used the same technique the old man used against the giant bear cutting down a tree in front of him not long after he fell to his knees as if he had depleted all the energy in his body
"How? that's impossible only beings a demonic core can do something like that"
