Chapter 1

In what seemed like an operation theater, a young black haired kid roughly of age 6 lied with operations marks all around his body while an old doctor stood at the side as he pulled his bloodied gloves off his hands.

"Tch! …what a waste of potential" the doctor said in a grumpy tone as he removed his mask.

Just then the door to the room opened as a man entered the room on his wheelchair. He donned a navy blue, skull-like gas mask with angular tubes at the top, a wide collar-like life support system around his neck with additional pipes connecting his front and back presumably a breathing aid, wearing a black suit over a white shirt.

"Calm down doctor, no need to get agitated like that though the experiment failed we still got some useful data" the man who just entered said.

"Indeed, it appears we underestimated the potency of that blood sample we got… though the kid had great potential to survive through these two years and assimilate with the blood he died the next second the process finished" the doctor said as he explained his findings to the man while disregarding the fact they were experimenting on a 4 year old kid for past two years.

Soon another man came in who took the kid's body and stored it in a body bag and left the place.

***

A black van was passing through the streets as it moved towards the outskirts of the city.

"Man that doctor is a complete psycho" the guy driving the van said.

"Ya! …hey, should we stop doing this?" another guy sitting on the seat beside the driver said.

"Are you an idiot or what… don't ever say that or else it will be us in those bags next time, we have already come too deep in this shit-hole to leave now" the driving guy retorted.

Soon the van reached an abandoned town at the foot of a mountain, throwing the bag in some alley they hurriedly left the place.

*drip* *rumble* *drip*

Just as they left heavy rains started pouring as if the nature itself was mourning at the heartlessness of human race. Thunder rumbled in the dark rain filled clouds, as heavy downpour ensued followed by thunderous roars. With a loud roar a lightning bolt struck the bag, destroying the bag to smithereens, engulfing the kids body.

The kids chest rose slightly, *ba-dump* the once dead heart started beating again while the kid laid there breathing slowly.

***

"Please… no more…" the black haired kid said his partially open eyelids showing his blue eyes who had a lifeless look in them something a kid of his age should never have.

His frail and weak cries of pain were ignored as an old man with weird round shaped googles entered his view smiling sadistically with some weird tools in his hands as he injected the kid with some red serum, while the kid screamed in pain.

Soon the room was filled with a mixture of cries of pain and maniacal laughter…as the kid's vision dimmed and…

"Huff! …Huff!" the black haired kid hurriedly woke up, rubbing his forehead he groaned in pain, with slight sweat trickling down his forehead.

Slowly opening his eyes he looked at his arms and limbs which were bandaged, he touched his bandaged chest.

"Eek! …man it hurts, where the hell am I and why is my body so small… what the fuck just happened and what are these thoughts…no… they seem like memories… ugh what is happening"

Sighing the kid tried to take deep breaths to calm himself as he cleared his mind and thought calmly on his current situation.

'Alright let's get this straight somehow I transmigrated while I was on my way home from my college and took over this body… a kid named Ritsuka who got abandoned by his family for being quirk-less… quirk, this words brings some memories from what I recall it was from some anime called MHA, where almost everyone had one of these quirks wanting to be heroes, fighting villains and stuff… man I regret now not watching that anime.

Anyway returning back, my memories of what happened after being in an alley for a week are quite obscured… all that comes to my mind is painful screams and some hoarse voices talking… but for now the main question is where am I?' the kid now Ritsuka thought as he tried to move his body, he frowned from feeling the still lingering pain.

Somehow he managed to leave the bed, walking out of the room he looked around to what seemed like a living room. He noticed the front door was open, walking up to the door while looking around he picked one of the knives placed in the knife rack on the table near the kitchen. Holding it behind his back, he pushed the door open to be met by the scene of a forest.

He walked out and looked around trying to see if someone was around. Just then he heard footsteps coming from one of the sides of the house. Being on full alert he watched as an old man with bald head, visible wrinkles, hooked nose and pronounce cheekbones. With red eyes, long eyebrows, long mustache and hip-length white beard. Wearing a black kimono and a white haori draped over his back.

The old man noticed him as he said "It seems you are all healed young-one and you can keep the knife away, I am not your enemy"

Though Ritsuka was surprised, still lower his guard neither did he put the knife away. Seeing that the old man sighed and said "I was the one to bring you here and heal you, if I wanted to harm you why would I save you in the first place"

"Very well, thank you for helping me but it would be better if I leave now… though I will be sure to repay you in future" Ritsuka said.

"Hmm… and where will you go?" the old man asked as he casually hovered in air a little, crossing his legs in a seating position, it looked like he was sitting on air.

Seeing the display of power, Ritsuka gulped but still replied "Not sure but I will figure something out eventually"

"Then why not stay here till then?" the old man offered.

Narrowing his eyes Ritsuka sneered and said "Old man, I not a naïve brat to think there is something like free lunch in this world… so what's the catch?"

The old man hovered silently for a while, his eyes half closed since the beginning. Seeing him contemplating Ritsuka stood there for a while as time passed.

5 mins, 10 mins… Ritsuka couldn't wait any longer as he shouted "Old man!" Ritsuka's shout brought him out of his thoughts as he looked at Ritsuka and said "So what were you saying?"

'This old man fckin fell asleep thinking' Ritsuka thought as his head twitched in anger.

"Old habits never mind, there is indeed something that I want from you" old man said in a serious tone.

"What?"

Old man bit his thumb as he held it in front of Ritsuka. Ritsuka wasn't sure what the old man was doing soon as if something possessed him, his eyes turned bright red and he felt his throat dry while he started craving for blood.

"Wh-what is happening to me… Grr! … damn you old man what are you doing?" Ritsuka said as he threw the knife in his hand, holding his neck falling to his knees trying to fight back the sudden foreign urge taking over him.

The wound on the old man's thumb healed as Ritsuka soon felt the urge diminishing and finally disappearing as he laid on his knees his hands on the ground supporting him from falling face flat.

"Huff! …Huff! …what was that?" Ritsuka asked while sweat covered his body while the bandages loosened from the sweat.

"As you saw you are no longer a human… what I mean to say is you are not a complete human. For some reason your body has the blood of a demon"

"What do you mean demon? I have never heard of them existing before"

"Indeed demons don't exist but quirks do, now are you willing to stay and listen to me"

Ritsuka nodded and held himself up, seating cross-legged on the ground, he looked at the old man for answers.

"So then first let me introduce myself, I go by the name Genryusai Shigekuni Yamamoto… people call me Old Man Yamamoto, so can you, now what about you?"

"My name is Ritsuka… I was abandoned by my family when I was 4, after that I don't remember much… though I think I was being used for some kind of experiment and was finally disposed of"

Old man Yamamoto nodded his head in understanding while he sighed at the way people looked at quirks. Shaking his head he looked at Ritsuka and said "It might be true, I found you a few days ago, lying naked in an alley… aside from burn marks and scars on your body, you were completely fine… now going back to the demon thing…."

After long explanation about this 'demon', Ritsuka started racking his mind, trying to add up things.

'So the previous owner of this body was experimented on that demon's blood which somehow merged with his body but he died and was thus thrown away after which I somehow took over the body and the mutation I went through activated, healing my body while this old man felt my mutation through his quirk and brought me here… from his words I am an anomaly since demon's die under sunlight while I am immune to it not to mention the old man said my aura felt like 'him' '

"Though it's hard to accept I am a demon, considering what happened just now, I can't completely deny it… so now what are you planning to do… kill me?" Ritsuka said accepting the fact he is now Ritsuka and this, his new reality.

Old man Yamamoto opened his eyes slightly showing his surprise since he didn't expect such words.

"Indeed I had thoughts of killing you when I first saw you but I wish to give you a chance… over the years I have fought and killed many demons, all the fight has weakened me and the fact that I believe 'he' is still alive doesn't let me leave this world…" Before the old man could continue Ritsuka interrupted him saying "So you want a successor and that happens to be me"

Old man Yamamoto though annoyed at being cut-off like that nodded nonetheless.

"…but what if I turn out like him?"

Old man Yamamoto looked at Ritsuka and said "Then I will kill you myself" as his bloodlust leaked pressuring Ritsuka, who felt the pressure suffocating just when…
