While jogging for several kilometers for his daily training Jayden is working up quite a sweat. His face was drenched in sweat while his bright green eyes looked forward with a grin. He was 6'3 and had a large, muscular frame and a few scars on his face from the tournaments he fought in.
He ran through the Golden Gate bridge and planned to stop at the end as he was done with his morning routine. he stopped to catch his breath and pulled down his hoodie showing his black hair and sweaty face.
"Almost their Jayden, keep going."
He had to get ready for his next tournament then he could relax for a while and bring read manga. He had just finished Demon Slayer not long ago and the last fight was still on his mind, His favorite thing to do was to put himself in the place of villains and see how he would do in their place.
he loved the Demon Moons, but more importantly, he loved Akaza and Kokushibo,. Sadly they both lost which he felt if it were not for plot armor they would have won that last battle. He sighed and kept jogging, but while he ran the bridge that was maintained well was destroyed and before he could even yell he died.
When he came too he was in front of a woman who looked to be in her early 20s, but she was not even paying attention to him. She was looking on her computer screen which he walked up to see what it was.
"WOW, IS THAT THE DEMON SLAYER ENIRRE ANIME ANIMATED!"
The girl looked at him without care and nodded.
"Yup, I can turn manga, comics, and anything I wish into perfect anime and animation, without any bullshit censoring that the snowflakes of the current human world have. Well, if you are here it means you are dead. What do you want, I am in a good mood."
He shook his head and took the chair next to her with his happy eyes.
"HELL NO! I want to stay, if you can animate anything at will can you do Charm of Soul pets or Legendary Mechanic for me. What about, Solo Leveling anime without a crappy ending."
Hearing his ideas she smiled and got to work on her computer.
"Not bad, I guess you can stay as until I finish this."
She was right as it only took her a click of a button and an anime on the level of the best-animated movies on a light novel, mangas, and video games. She could also make perfect video games about anything she wanted and he ended up staying with her for about 80 years.
In that time several more souls had passed by and had gone sent off to their dream worlds and yet he could careless. He later learned her name was Naomi and she was a goddess of reincarnation, but she was bored and became a neet.
She could see anime from other worlds even which meant they had near endless time to binge-watch anime. She also could make perfect food by just willing it into existence. He was more than happy with his anime binge-watching life with Naomi the goddess, but all good things come to an end.
While they were watching an anime from a world several light-years from Earth they heard a crumbling sound. They looked at it and they saw that his right arm had crumbled while he started at it in shock. Naomi sighed as she paused the anime.
"You knew this would happen in time right Jayden?"
"Yeah, I watched and read enough fiction to see where this is going. Souls cannot stay in soul form too long right?"
She nodded.
"Your soul has stayed for over 80 years in soul form and it reached its limit. Normally each person I reincarnated only gets one wish, but for a friend, you get three. Don't tell anyone, though, your world is MHA."
"Crap, you know I hate it."
"Exactly, you are wrong. How could you hate it when y-"
"Heroes suck, and Deku sucks. Fine I will get my wishes, is my appearance free or do I got to choose that."
"Free, I am your friend. Not a bitch."
"I want to look like Kokushibo, as for my first wish I want to be a demon of Demon Slayer with the blood purity of Muzan, but the power of Kokushibo."
"That is two wishes, but it will be done. As a freebie you will be immune to the sun can't have such a stupid weakness now, can you. You also won't have the extra brains and hearts, that was excessive."
"Will I know Moon Breathing?"
"Included in the package duh."
He nodded and thought about it.
"For my last wish, I want to be born 12 years before the birth of Deku."
She nodded as she looked at her computer and walked up to it.
"I enjoyed your company, Jayden. Enjoy your new life as a badass demon. Surpass Kokushibo and show the heroes why they are wrong."
He stood up and made a joke before leaving. He raised his right hand and looked at it with a smile.
"I would salute, but in this state no dice."
She rolled her eyes and gave him peace of good news.
"As you are will be a demon you can eat human flesh to grow stronger. Still don't you worry, you will never just go crazy if you stop and you can even eat normal food as a substitute. Still, why would I make your life terrible? Have fun."
She launched him through a portal to his new world and the next thing he knew he was being born. It was quite strange for him as he was coming out of her. You were not supposed to be self-aware when this shit happen for good reason and he cried from pure trauma.
When he opened his eyes he saw he only had two and he felt no different than a baby. He would roll his eyes if he could, but he was forced onto the nipple of his mother. He started to suckle instinctively.
His mother looked to be a gorgeous Japanese woman while his father was just as handsome. His father went to look at him while he nursed and smiled.
"He is sure to be a handsome boy in the future, Kanna."
She smiled as she leaned on her husband's chest.
"He takes after you, Tashiro."
The doctor came over and congratulated them.
"What do you intend to name him?"
His father smiled proudly and looked at him.
"Kokushibo Yukimura."
As his parents looked at him he saw pure hope in their eyes. He did not know why, but he had a few theories. Either they were quirkless and hoped on the off chance he got a quirk from his grandparents if they had some.
if not they might just want a happy family, but either way he was a little happy. His family in his past life died when he was 9 in a fire and he grew up in an orphanage. He was glad to have a family this time.
he fell asleep and when he came home he saw that they lived in quite a modest home.
His mother Kanna and his father Tashiro both looked to be in their early 20s. From what he had overheard he was correct that they were both quirkless, but his father got a decent job as an owner of a small restaurant."
As for his mother, she worked as a waitress, but they had had him and hoped he could become a hero in the future. It would keep him from being bullied like they were in their youth as the quirkless and those who had 'Villain quirks', had bad lives.
They hoped better for him and for the next 4 years he lived a comfortable life. It was not flashy or expensive like he had lived in the latter part of his life, but it was happy. While he was in his home with his mother in the kitchen on the high stool he felt his body flair in pain.
"AHHHHHHH!"
Hearing her son's screams she rushed to his side as she saw his veins bulge and his eyes bleed.
"KOKUSHIBO!"
She picked him up and as his father was not home she rushed to their car and drove to the nearest hospital while he was still screaming in agony. He forgot that becoming a demon was not just a quirk, it was a total species change.
Lucky for him he would not lose himself to his demon side and he could still control himself. He also felt a rush of memories of his breathing technique and Blod demon art that would take some serious training.
Kanna rushed to the front desk while a few nurses who heard his blood-curdling screams ran to her.
"MISS, COME WITH US!"
Kanna ran with the nurses while they put him in the ICU, just from the sound of his screams. A doctor rushed in who had a healing quirk as he looked at his skin that was getting a little paler and a pair of red marks appeared on his face.
He got a syringe and injected Kokoshibu with a very strong anesthetic to be used on peaple with healing quirks and from there he blacked out. He did not wake up for several hours as they injected enough to knock out a person with regeneration for hours.
When he woke up he saw his face was covered in wet bandages which were actually his blood. He felt he was tied up to the bed with strong straps and when he moved his head the doctor walked to him.
"Young man, can you hear me?"
"Y-yes. Where is my mom?"
The doctor sighed and called in his parents and they were shocked when they saw the body bandages. They went to remove them, but the doctor stopped them.
"Please, you should get ready for a lot of change in his and your lives. His quirk was is not a gentle one. He will need a lot of support for the changes he went through. I just hope you won't abandon this child when you see him."
Kanna was pissed at his words.
"I would never leave my child."
His father nodded and they looked at Kokushibo who knew what they meant. He could feel it already, he now had 6 eyes and he had to say looking in 6 different directions was awesome. Not only that, but he had something that he did not ask for, but he thanked his friend.
She gave him complete compiled memories and experience of the original Kokushibo so as long as he trained hard, he could surpass both Muzan and Kokushibo. Plus, how would eating humans with quirks affect him, he could hardly wait to sink his teeth into the scum of the Earth.
He felt the doctor remove the straps first and help him sit up. Slowly, but slowly the doctor removed the entire bandage showing his parents his new face. They were shocked as he now had 6 eyes which were bright yellow.
His skin was so paler, but not too pale. Kanna wrapped her arms around him as she did not care how he looked, she cared more about how he would live from now on. He would live a hard life full of bullying as this was a mutation quirk in her point of view.
As for his father Toshiro he too did not care how his son looked like. Some of the best friends he had in his life were peaple with mutation quirks.
"Kokushibo. Before you look in the mirror just know we love you no matter how you look like. How do you feel?"
"Like I have 6 eyes, It is cool."
They saw how his eyes all moved around like a chameleon, which was freaky. Still seeing him smile as he use his new eyes they felt he would be ok.
"Do you feel different Kokushibo?"
He nodded.
"Strong."
hearing him say strong they were interested in the true abilities of his quirk. The doctor saw how they did not react negatively to his mutation and sighed in relief that they were good peaple.
"We can test his quirk here, do you want to do it now or later."
His father shook his head.
"Later, my son just went through unimaginable agony. He needs to rest."
The doctor nodded and let them go on their way. His parents wanted him to wear a hoodie to hide his eyes for his sake, but he did not want to. He was used to being bullied as he was an orphan before.
As he walked out of the hospital some peaple saw his eyes and they flinched in disgust or pity. One thing was that he could look at those people with just one eye to freak them out. he was glad that he would not stay little all this time and he would have to stop his aging himself.
He planned to stop when he was 22 as it seemed to be a perfect age. Not too young, or old. he also had to learn swordsmanship as just having memories did not mean he had experience. He looked at the sun, one thing Muzan never could do.
What would the Michale Jackson look-alike say if he could see him now?
At the start of MHA, Midoriya was 14 and when he starts at UA he was 15. So Kokushibo will be 27 when that starts. His parents will not be around for long, Villain backstory after all.
