Self-Power Augmentation

Chapter 1

At kindergarten

A green haired boy could be seen playing all by himself in the sand pit making a sand castle, when suddenly someone taps on the kid's shoulder and he turns around and saw a girl with black hair standing behind him.

Momo: Izu what are you doing all by yourself?

Izuku: I was making a sand castle wanna join?

Momo: sure.

After she say that she sits down next to him and both of them starts playing with the sand.

Momo: Izu did you get your quirk checked?

Izuku: Not yet, but I'm going there tomorrow.

After izuku says he hears someone calling his name and he look around to see who and and where the person and saw both kaminari and kirishima running towards them, suddenly both them then jumps towards izuku. Seeing this izuku simply moves out of the way causing them land on the sand castle. Seeing the sand castle getting destroyed by them momo starts crying, seeing momo cry both kaminari and kirishima look towards izuku for help but instead of helping them, izuku just looks at them and smirks.

As Momo continued to cry more and more kids started arriving to see what was going, some of them started to calm momo down while some of them were scolding kirishima and kaminari, eventually the teacher comes in and the kids told her what hall and both of them got scolded for what they did and the teacher managed to calm momo down.

Izumi: Onii-chan, why didn't you-

Izuku: I know what you're going to say but izumi the thing is there was no fun in that. You should have seen their faces when they saw momo was crying. It was hilarious.

Izumi(chuckles): You're evil.

Izuku: I know.

Time-skip, Next Day

Izuku was presently in a hospital with hi sister and his mom waiting for the doctor to come with their quirk results. While waiting for the doctor Izumi was ranting what kind of hero she was going to be and izuku was silently sitting on the chair waiting for the doctor to arrive. After a while the doctor arrives with results and glance at izuku with pity.

For some reason when izuku saw the look on doctors face, he got an urge to beat the shit out of the doctor. He didn't know why but he didn't like the look the doctor was going him. The doctor then sits down on his chair and look at his report and then he looks towards the yagi family.

Doctor: Mam it seems like your son is... quirkless.

Inko: what?!

Doctor: Yes man, you see the thing is there isn't any extra toe joint in your son at all. And we ran a blood test just to make sure and it showed no active signs of quirk. But the good news is that your daughter has the same quirk as you but is much stronger. If she trains herself every day, she will become an awesome hero.

Hearing that inko turn towards and pick Izumi up and started talking how she was going to be an awesome hero and how they will train together and all, seeing this doctor again look at izuku with petty which causes to grip the all might figure in his hand.

Izuku(thought): Don't... Don't give me that look.

The anger that izuku was showing causes his eyes and hair to go pink for a brief second which went unnoticed by everyone, after that all three of them thanked the doctor went towards their car. While walking their way towards the car izuku looks towards his all might figure and saw it was broken and seeing this izuku raised an eyebrow but didn't have it much thought and throws it away.

Timeskip

After a while all three of them arrived at the house and went inside and toshinori was sitting on the couch watching something, he then looks towards the door and saw Izumi, inko and izuku were taking their shoes off, seeing this he stands from the couch and went towards them and asked

Toshinori: So how did it go?

Izuku though wasn't interested in their chitchat and walks towards his room still thinking about what happened at the hospital.

Izuku: ughhh why can't I just forget about it, it's making me angry

With Izumi

Izumi: So dad what are you watching?

Toshinori: Me? Well there this villain that broke out prison and was going rampage in the city, a hero was close tried to stop him but instead was brutally killed by the villain.

Izumi: Wait, where?

Toshinori: Let's see if they are still talking about it.

After toshinori says that he turns the T.V on and saw that No.8 hero yoroi musha was able to defeat the villain but the other hero died. While reports were talking about the situation a reporter said that got stuck in izumi's head.

Reporter: Sometimes weak people needs understand their limits otherwise more people will get killed because of their recklessness.

After the reporter says that toshinori turn off the T.V and Izumi goes in the kitchen to see what inko was cooking and after a while she went into while thinking about what the reporter said.

Izumi(thought): what if this same thing happens to my brother, what if he got killed the same way this hero did, he doesn't have a quirk to protect himself or run away from the danger.
