Chapter 1

Drip....

Drip.....

'It hurts....so badly...I want a hero to save me..'

The boy survived the first few months of the testing and his mind was nearly at its breaking point. His body looked dissemble from the torture of his limbs being removed painfully by the doctor. His eyes dried and red from the endless crying, his face still looked healthy for some reason despite losing so much blood.

It turns out the doctor has been taking breaks and allowing him to eat so he wouldn't die on him.

"....I....need....to ....

....

...

Survive..."

The doctor walked back into the room holding a syringe with blue liquid inside it.

"Seems since you survived this long, I'll do the honors and give you the second test. This majestic blue liquid is from the beast I told you about a few months ago. The toxicity level is extremely high, even the smallest drop of this can burn through even metal itself."

The doctor said walking up to the kid who only nodded with his body almost becoming unresponsive. The doctor enter the syringe into the kid's left arm seeing his blood vessels/Veins glow purple despite the liquid being blue.

"What's this? Is the blood adapting to your body? If that's the case it means that you're somehow immune from to the toxicity and radiation from it."

He noticed that KU was screaming in pure torment, his eyes glowing purple before changing to blue with cat slit pupils, his hair turning Snow White and two dark blue horns that becomes lighter to the tip.

The anguish wounds healing to the point that it showed no sign of it being severed off. The veins in his body began to glow changing the boy entire physiology.

CRACK!

The sound of his bones cracking and being modified to adjust to such a toxin and radiation.

"MAKE IT STOP!!!"

The boy cried tears of blood while.....laughing maniacally, it was like he was enjoying the pain from the inside out.

"HAHAHAHAHA!! GIVE ME MORE PAIN!"

The boy asked for making the doctor smile with agreement injecting more of the blood into his system as the boy continued to laugh despite being in pain.

"Heheh!!"

The boy slowly started to calm down from the pain finally disappearing, he never thought he would lose his mind from the pain but the final test would help him truly understand the doctor research.

....

....

In the simulator room right on the far left of the facility stood the boy and the doctor who stand at the center of it. The doctor took a glance at the boy who nodded to something.

[Flashback 7 minutes ago]

The doctor freed the boy as he rubbed his wrists. He sighed and now that the experiment over he had to tell the truth.

"Y'know KU, I never wanted to do this.." This caught the boy's attention. He never thought the doctor would say that.

"I, Miyamora Sakai have committed sins that were beyond monster like. For 23 years I was kept here behind my will by a villain named, All for One, he's behind the entire project. The kidnapping was all his doing but I needed someone to help me and then I found you on my way home back from this place, your family left you their after they was paid millions of money. So I used this opportunity to fool All for one and bring you in so I can make you into a hero who would stop him from succeeded in his goals."

The boy took a step back, he realized that's why he was treated differently from the other kids. The way he was raised from training, studying, laughing with Miyamora was because he was basically his father figure and he cared more about him than he did about himself.

Should I be angry about this? He practically raised just to defeat the villain who saw quirks as something that overpowers the weak.

The boy mind set was in a conflict but in the end he gave and hugged him tightly, he could never be angry at him especially trying to find a way to stop All for One.

"I promise that I will defeat All for One and make you proud."

The man then smiled warmly accepting the warm embrace, he truly raised someone who can be more than something he was made to do.

"Now let's begin for the final test, then we can set the kids free." Miyamora patted the boy's head and open the door to the hallway as the boy followed behind him.

[Flashback Ends]

This time I must make sure I pass this test then I can get the kids out of here. The boy then looked up to see a masked man looking down at him, that had to be All for One. I then smiled menacingly not caring about what lies ahead.

"Be ready for anything." The doctor whispered in my ear and walked over to another doctor, a fairly old man of a portly and short stature. He is completely bald and has a very large and bushy mustache. wears a rather peculiar set of goggles that are shaped somewhat like gears, along with a white, buttoned-up labcoat.

"Now for your final test..."

The odd looking doctor said through the intercom allowing me to get ready for what his last test.

The door in front of him opened up as the kids he tried to endure the experiments for were pushed out shocking me. and Miyamora who was flabbergasted by this.

"You must show that you can kill without having any regrets. We need to make sure we didn't spend so much on you." The doctor explained as I clenched my fists refusing to kill the kids I'm trying to save.

"It seems we have our first defective, maybe he needs some motivation." The doctor pulls out a gun and shoots one of the kids in the head, my eyes pupil shrunken as I let out a sorrow scream.

"NOOOO!!"

The radiation emanating from my body increased from his sadness. The kids stared at the body before one of them walked up to me with a smile that was warming my heart.

"Stay back! I don't want to hurt you!"

"It's okay, I knew we weren't going to make it anyway...we'll be fine if you just kill us. After all you deserve so much freedom especially since you spared us from the experiment."

I felt I was weak that I couldn't help them enough, I raised my arm into the arm before being it down ripping the kid in half. I regretted being too late to save them now I have no choice but to finish it.

....

.....

Flesh, organs, and even body parts flew in the air before the entire room was painted with red and there he was standing in the center of it all, tears of blood flowing like a stream down his face. His hands and mouth covered in blood of the family, this broke the mind set of what he stood for and now the family he called siblings were gone.

"Incredible...that display of power of mastered can match One for All!" All for One said before turning off the screen after seeing enough of it.

"Now that we have what we needed it seems that it's time to end the Project:???" The doctor said looking at Miyamora before pointing a gun at his head.

"What are you doing!?"

"Nothing personal but your research will continue on without your help!" Before the man can pull the trigger the boy burst through the wall and kicked the gun out of his hand. He seemed to furious — no beyond that he then gut punched the doctor out of the building with brute strength.

"Let's get going!" The boy helped his father figure up and ran straight into the lab. They both knew that they had to destroy the research before All for One has it.

Once they made it to the lab, Miyamora handed the boy a bag and two hard disks. "Take these with you and go! I have to make sure all the files are deleted and that bag has a storage of lifetime supply of food to help you eat."

"I can't leave you behind!" The boy tried to argue before and explosion behind him knocked out of the building falling down.

Thump!

His body hit the ground so hard he created a small crater in the ground. He stared at the starry night sky, and was shocked to see the outside world but he got back up and noticed that the building was collapsing on itself. He then saw Miyamora jumping down, stumbling his landing.

"You're alive!" He was very glad that his father was alive, he ran up to hug him but turns out he caught a whiff of blood.

"...I'm sorry pal....I guess times up..." Miyamora said as he coughed up blood, laying the man down on the debris which remained of the facility. The boy began to cry into his chest hearing his heartbeat slowing down.

"Just wait, the heroes will come and you'll be fine! So stay strong..!"

The boy kept pressure on the wound on his chest it seemed something went through his body. "....listen Kaiyu....I want you to become something greater than a weapon...live the way you want...I'm sorry for not being a great father but you must understand that I will always love you as my son..."

The boy continued to listen even though blood flowed down his cheeks.

"The power you possess is far greater than what a quirks mean but I left everything you needed to know about the quirk I gave you inside the hard disks make sure All for One doesn't know about it...." Kaiyu saw the life fading from his eyes which made him feel more grief.

"So live...as you want to and let nothing stop you from your goal....And go find your real family" The man eyes finally showed the last of his smile before dying right in his arms.

"....." Kaiyu felt something he never felt before, the rage to kill every villain no matter who it was.

"AAAAAAAAHHHHHHH!!!"

A blue light engulfed the entire area destroying everything around him. The light began to engulf the entire island.

—————-

10 minutes later

—————-

The heroes finally arrived to see that the light disappeared showing nothing more than Kaiyu walking out of the smoke with tears of blood streaming endlessly down his face, his bangs covering his eyes.

"Young man , are you alright?"  The hero known as All Might offered his hand but he felt as if the sun was close by making him step back.

"It seems there's some type of heat emitting from his bod!" All might acknowledge the other heroes who got ready.

"...."

The boy looked up at the pro hero with no emotion detected whatsoever. "I'm.....sorry.." he seemed to pass out before taking another step.

The other Heroes looked at the destruction of the site in front of them. How can one child do something like this?
