Hisashi, Izuku...he is dying. Those words alone struck at heart. The cries of his wife was enough motivation to get his ass in gear. He worked to hard for it to end like this. He left her alone to long but when Izuku came everything was alright. The sudden news of his only son dying terrified him.

With his quirk, he combine many different properties of other quirks such as hyper regeneration and recovery, endless stamina and endurance, unyielding strength and power. It was the most frightening yet resolving conclusion he had come up with. Making a combination of not two or four quirks but twenty. If this didn't work than his son would mostly be a vegetable covered in the quirk scars of his father's creation.

He only had so much time! It was now he had to do it. Putting all the quirks into a syringe filled with highly dense protein might have help the process of absorbing the quirks but Might was all he can expect.

It didn't take long to get to the hospital. I saw my own son strapped with all of those... cords and needles. It sickens me but I must persevere for my family.

Inko was asleep still holding onto our sons small helpless hands. I walked in the room unnoticed. The camera was there so I simply disabled it with a short emp blast that covered the entire floor.

In that moment of darkness came the screams and shouts of patients, visitors, and the hospital staff. My time was short and better keep it that way. The syringe was now upon my sons chest. Forgive me Izuku, if you mange to make it out alive then please do better than what your useless father has ever achieved.

It was quirk the liquid entered my son. He was now breathing rapidly but I feared that the worse case scenario would be he would die right there or turn into a monster but nonetheless die.

Inko was waking up but I did not look back. I ran out making sure I would disappear for good. The money was there enough to support them for another fifteen years if they spend wisely. Sadly I know for a fact after this moment I won't be leaving the market alive.

Ten years later~

"I'm sorry young man but you can't become a hero without power." Those words stab right through Izuku's aspirations. All Might already had taken off to turn in the criminal.

"You knew it Izuku, but you just couldn't see it for yourself." He told himself as his tears flowed down the cheeks of once a aspiring hero. Walking past the crowd to meet his end by the green blob that already tried to make him his vessel.

"What's the point?" The image of his mother holding him in sadness as she did not believe in him.

"Why even try?" Another picture of him being beaten down by his childhood bully over and over again.

"How come I did not accept it sooner?" And finally a last memory of his idol, All Might telling him he can't become a hero.

"Kid! Stop!!" Izuku heard the voices of the pros that did nothing to help Kaachan. Good for nothings all of them, even him. Born with no power to use is really pathetic. But... those who has the power to do something but choose not to use it...they are inexcusable scrums of the hero society.

That look of pain, the expression of needing help reached Izuku. He saw through the eyes of Bakugo, his bully needing help. Without a second thought, Izuku ran towards the danger. He was not doing for himself, not for Katsuki, no he was risking his life to fulfill the obligation of any hero by instinct.

Throwing his backpack as a way to create an opening, Izuku saw the glass shards on the ground. Hastily, he grab it not caring how his hand placement was. The sharp pain in his palm was ignored and thus letting the adrenaline move throw freely. The villain flinched downward from the backpack.

Now was the chance to strike. With a shout of all his will, Izuku brought down the glass shard down on the green blobs eye. His whole hand was covered in blood, most likely from the strike he just dealt.

His bully finally freed himself from the cliches of his captor. Izuku felt the rush, yet what mattered was that Bakugo getting out of there. In a flash of a second, Izuku saw his idol finished the job but before he could, All Might apologized briefly about abolishing him.

The next hour became a blur. Bakugo was getting praised for having a quirk. Izuku did not want to be lectured by some half-ass heroes so he left. "Hey! Where are you going? Your hand is not treated!" Kamui Woods shouted at him.

"Oh so now you care, where was that when Bakugo was held captive? I didn't see you try to stop me or save him!" The green haired teen yelled at the heroes leaving the reporters silent.

With that said, Izuku left the scene to annoyed with the turn of events. As he was walking on the road which took a long detour home, Midoriya needed it. As each step was taken, he recalled all the things that prevented him from being a hero. Quirkless, no support from his family, and the downright discrimination that came with his status.

Everything felt pointless now, that is until he met him. A killer as he first saw him being. It was clear that the target to his sword was killed. Izuku knew fear yet he wasn't so scared of this presence.

"Who goes there?" Asked the killer.

"A boy sir." Izuku said to him.

"A boy yet you look broken." He claimed.

"That's what you get for being quirkless." Izuku stated.

"Then either leave now or you will meet the end of my blade."

"Please do, life just sucks and I can't become a hero all because of some damn lack of a power to be born with." Izuku pleaded empty words.

"A hero huh? Tell me kid what makes a hero?" He asked me lifting his sword off of the dead person.

"A hero? A hero is one who smiles in the face of danger. One who faces fear itself to give others hope and courage. Through his actions of courage he brings upon the hope of a better tomorrow for not himself but for the sake of those he saves. He won't ask for nothing more than a smile on the saving faces of the innocent. Telling them 'it's all right why because I am here!' That's my meaning of being a hero." Izuku answer his own ideology of what it means to be the thing he can't become.

"Kid, with that mindset I am surprised that you are trying to end your life. But I can't judge you. So how about this you train under me and we will become the heroes this city needs. Purge the world of money greedy heroes who take advantage of their powers to only benefit themselves!" He sheath his blade and walk towards the boy.

"But you kill, how can we be heroes if we kill others? The thing we do isn't what we aspire to be but the opposite!" Izuku question him.

"Listen kid, this world is not all black and white. There is a gray line, it's called being a vigilante. Sure there will be cases were killing is upmost mandatory but otherwise we are here to send a message and give light to a new world. So killing will almost never the option unless it is urgently necessary." He told the teen.

Izuku thought very hard on his offer, a chance to rid of the world of people whose abuse the title 'hero'. He looked at him with clear clarity with no hesitation he said. "I will rid the world of fakes and give the real definition of a hero." To that statement he grinned at Izuku.

"Kid, I am the Hero Killer and the road ahead is going to be long and hard but as long as you have the determination and conviction you will succeed!" He shouted giving me a combat knife. "Now then let's get to training."

As the months had gone by, I later learned that I indeed had a quirk. It wasn't a noticeable one that can inflict damage on others but a very valuable one to me. My ability was that I can instantly heal all of my wounds. From fractures, gashes, slashes, scraps, and burns. I can even repair vital organs like my heart, brain, and etc. What really got me was that I can heal back my limbs if they were dismembered.

It indeed was a powerful quirk that I did not abuse but took advantage of during the heat of battle.

Of course there was pain but if would first burn then subside and finally disappear. My Heroic assignment was Kamui woods. He did not recognize me at all with my hood up and my longer hair but nonetheless it was first hard battle.

"Who are you?! Stop right there Villain!" He shouted.

"Who I am is nothing more than a mere assassin, you abuse the title of being a hero so you can earn your fame. And as for that second statement, you should think twice about you call a villain. You don't think I saw let that kid suffer third degree burns when you obviously had the power to save him?" Izuku spoke in a dark tone unsheathing his short blade.

Kamui looked in shock of a hero duty gone wrong. "There were others that needed help!"

"What "others"? You saved everyone from that fire except you waited for the boy's father to break in the door and get him and back halfway. That's when you "saved them!" Izuku shouted at him.

"You wouldn't understand, your just a kid!"

"A kid, well at least this kid tried to save his classmates from a green turd stain of a villain a few months back! Unlike some "pro" heroes." With that the teen charged at the wood hero instantly slicing his right eye.

Not letting him get a scream out, Izuku quickly elbowed the hero in the throat and use one his smaller knifes from his thigh holster and quickly stab the heroes thigh. Preventing any sound besides the struggle for air, Kamui Woods fell down to the cold ground as Izuku sheathed his bloody blades except one. "Who... are... you?"

"Like I said, I am nothing more than a Heroic Assassin: Smear." Izuku grab his blade and strike down at the spine of the collapse hero. His cries were not loud due to his damaged tonsils. Izuku made sure to make him paralyzed for the better.

Once Izuku had finished the job, he walked away toward the underground base. Where his teacher was awaiting.

Although upon arriving home, he did not see him, Izuku took the time to lay down on the couch and nap until his sensei's return.

"Kid. It's time to get ready we are going after the new hero Mt. Lady." Stain woke up Izuku from the couch in the hero killers underground base.

"Right Master." Izuku got his cloak and short blades ready for another night of a hunt.
