Five months had passed.
Izuku had sold some of his Allmight merchendise to get money to buy equipment.
After a long search through the dark web, he found some random person selling hero blood, exctracted from the fights they had and kept for sell.
He had never been so glad that there were all types of people in the internet, and bought what he needed.
He thought it highly unlikely that they would have Allmight's blood, so he instead searched for other strength based heroes with strength related quirks.
The only blood in stock currently was Mirko's, so he bought it.
CuteFangs: thanks for buying greenie, you better give me what i asked for or i'll find you.
Instead of asking for money, this person asked for a vial of blood, with a straw.
greenie: i already sent it.
"This is weird but eh. I've had weirder interactions before." Izuku said.
He had bought all he needed in order to study blood, chemicals, extract certain things from blood, and all that he needed.
A few hours later, the blood had arrived in his mail. He quickly got it and carefully rushed to his room to study.
He spent hours carefully studying the blood. He tried to see how canceling a quirk was possible. He thought that if you could cancel it, you could also copy it.
He tried to use the internet to find out how quirks affect the human body, blood, and brain.
Since the normal internet couldn't answer him, he went to the dark web again.
He found out from a very secure and interesting website that at two quirks, the brain power of an individual is immensely reduced. At three quirks, they lose control of their body and go into a vegetable state. Dual quirk users avoid this via the quirks combining in the quirk gene, making them one.
After hours of work, Izuku found a way to make the quirk gene in Mirko's blood accept and combine with any other quirk that came in contact with the gene in a specific way.
The next day, he skipped school to find a way to exctract the quirk gene in the blood.
It took all day, but eventually he found a way to do it.
"Ok, this is it." Izuku said as he held a seringe filled with Mirko's quirk gene, specifically, the super strength. The bunny features were inhereted by the woman via her parents. The liquid was a blue color.
Izuku grabbed a rubber band, and put it on his arm above the vain.
Izuku took a few deep breaths, and slowly lowered the seringe to his arm.
He wanted to close his eyes in case this failed horribly, but he had to keep them open to make sure he did this right.
The seringe pierced his skin, and he pushed the back of it to inject the quirk.
He watched as the liquid went into his vain, and his eyes widened when it glowed for a few seconds before diming a bit.
After the whole thing was injected in his arm, he wrapped bandages over the vein, and waited for it to take any effect.
Nothing happened for a few seconds, until the pain hit.
"Argh! Umf!" Izuku yelped as his veins glowed a bright blue color, and he fell to the ground.
He tried to scream, but he couldn't.
He felt his bones and muscles growing. It was painful, his eyes were shut, and he prayed that the pain would go.
Izuku thought that he was going to die, until the pain stopped.
He took a few deep breaths to calm his heart.
He got up on surprisingly unshaky legs, and opend his eyes.
His clothes were tight, so he took his shirt off.
What he saw surprised him. He had muscles, real and well toned muscles.
He poked his stomach abs in awe.
"Ok, so Mirko's abilities enhance every aspect of her body. Her looks, her strength, her sight, her smell, and her reaction time. That's only what I remember, but I can already feel better than I've ever felt before." Izuku mumbled.
Izuku's head snapped to his stomach, as it growled.
He facepalmed and said, "I forgot that these people need to eat a lot more than the average person. Doesn't matter, I have money for food."
