A/N:

Okay so after reading the chapters in the manga with Eri in them and seeing her growing relationship with Midoriya, I've come up with a story! It's mostly comedy and it set ten years after the series. It's a little AU too but nothing too major! Chapters also range from short to long so don't be surprised.

There are a few OC's as well! Anyway, please enjoy!

Episode 1: Sister of the No. 1 Hero

Have you ever wondered what it'd be like if you were related to the Number One hero…?

"Find cover!" I hear Shouto shout as he slides down on an ice trail, directing panicking citizens to safety. Along with him are Creati and Froppy, who quickly assist in helping people get away from danger while still fighting off enemies.

Who are these enemies you ask?

The most typical of typical bad guys – Death Bots!

Created by whom?

A man by the name Inventor. He's a villain who appeared a couple of years ago and went full insane maniac on the city. His quirk Robotics (ロボット工学, Robotto kōgaku) allows him to create robots out of metal parts. Sounds cool right? I suppose but the catch is he can't use parts if they're intact to something else which means he'll have to dismantle something first.

Hence the destruction of the city…

"Ha! Just try and stop me heroes!" Inventor yells loudly as he makes waste of the city in his giant robot suit.

After nearly getting everyone away, Shouto directs his different colored eyes to the enclosed villain. He lifts up his left arm and shoots fire towards the giant robot. Unfortunately though, the fire is stopped at the last second by the other surrounding smaller droids, which are destroyed instead.

"Nice try!" Inventor snorts.

Shouto frowns.

Creati and Froppy join him by his side.

"There's no way to get close to him without his bots getting in the way." Shouto says in frustration.

"What do we do then?" Creati asks, "We can't just let him destroy the city and make more of those things!"

Froppy places a finger on her lip thoughtfully, "We need to find a way to distract him somehow."

"Yeah, something tells me he's prepared for our attacks!" Creati says.

"And with the other heroes busy right now, we can't get back up in time," Froppy adds.

Shouto narrows his gaze, "We just have to hold him off long enough for him to appear."

With that he propels himself into the air with a crooked pillar of ice. I watch in awe as he puts both hands together, blasting a combo attack with his fire and ice. In seconds, all of the surrounding smaller robots hovering in the air are destroyed.

At the bottom, Froppy uses her tongue to toss the robots around while Creati manifests a sword and slices at them.

Pieces of robot remains are tossed over the car I hide behind, and I flinch as they crash into the ground.

"Maybe staying behind to watch was a bad idea…" I mumble to myself as I hear a scream. I whip my head to the scene and is shocked at the sight that presents itself to my red eyes.

Being crushed by the hands of the enormous robot suit are the only three heroes available. I watch in horror as they struggle and scream.

I gasp.

Should I do something?

Using my quirk has always been something I avoid no matter what. I may have better control of it now but it's still extremely powerful and dangerous.

Plus, how in the world can I get from here to up there in time?

I bite my lip.

I'm here. Yet I can't do anything.

"Where are you?" I ask anxiously, placing my hands together as if praying, "The city needs their Number One Hero!"

I look away even though I don't want to. I'm not supposed to.

Inventor laughs, as if he's won.

"Looks like with him not here, my plan can continue with no issues!" he says, bringing the three heroes to his face with his suit's hand. "I guess I should dispose of you all first, how should I do it?"

They all struggle to get free and wince at the pain.

"You won't win Inventor!" Creati says, her voice barely making it out.

"Oh c'mon!" Inventor laughs, "This fight is over. This suit is almost invincible. Nothing you can create would be able to take it out fully," he turns to Shouto, "It's also fire and ice proof, so don't bother!"

The heroes grimace, and so do I.

Inventor laughs again, "Ha! I love those looks on your faces! They make this all the more satisfying! Getting rid of some of the best heroes from the Hero Association will be most rewarding for me and the Villain World!"

He lowers them until they're at the level of his suit's torso, at that moment a cabinet opens in the suit and a gun emerges.

Their eyes widen, and so do mine.

The gun readies fire, a bright blue beam starting from it. They'll be vaporized. That can't happen!

Suddenly, my plan for speculation is no longer important. My legs begin to move on their own. I push myself off the ground and come out to the open. I run frantically to the feet of the giant robot suit, my white hair flowing, my pinkish face sweating bullets and my heart pounding wildly.

My legs begin to buckle but I can't back down now.

I'm here…

I can try.

I can do something!

I close my eyes and scream.

"LEAVE THEM ALONE!"

My voice echoes throughout the city, and I can feel several eyes on me, from the hiding citizens to the three Pro-Heroes and Inventor, even the eyes of those watching from a screen at home.

My heart continues to race as I open my eyes and fix my gaze on the villain above me.

Creati, Shouto and Froppy stare at me bewilderingly.

"What do you think you're doing here?" Creati, asks me in shock.

I can only stare back at her, not knowing what to say.

"It's too dangerous, ribit!" Froppy shouts her voice loud but calm. "Go while you still have a chance, ribit!"

"I can't!" I yell back, clenching my fists, shaking my head furiously, "I can't leave you guys! I won't! A real hero wouldn't abandon those in need!"

I say things without thinking, as these are the words I've heard for so many years that they've become a part of me.

Shouto continues to stare at me before turning his head back to the beam that is about to fire. He turns back to me with a specific look on his face.

One that told me he had a plan.

"ERI!" he screams to me. I lock eyes with him, "CALL FOR HIM! NOW!"

I stare at him and barely have time to think, as I notice Inventor's robot suit shift.

"Not so fast!" he says, "I won't let a mere girl ruin my plans!"

He moves the others up and aims the beam at me. It fires.

My eyes widen.

I don't scream.

I don't cry.

I don't move.

I just stand still. This is how I am when it comes to danger. Even after all these years.

Have you ever wondered what it'd be like if you were related to the Number One Hero? Sounds awesome right? I suppose it is, but it definitely comes with a lot of trouble. But what do you expect when you live in a world like this? Still…

Still, only seconds away from impact, I can't help but whisper his name…

"Izu-niisan…" my voice is so quiet, it's like I thought his name instead.

…here was the thing, when worst came to worst, I had someone to count on, someone to cry out to, and someone to call my savior…

In a split second, I'm rushed away from the blast and it hits the ground, leaving a giant crater. Dazed at first, I soon recognize the familiar warmth of his arms. I smile because I know everything's going to be alright.

I close my eyes. I can't see his worried expression but his voice gives him away.

"That was very reckless, Eri." I open my eyes to meet large green ones, "Are you alright?"

"I'm just fine," my smile widens, "Izu-niisan."

…Someone I call my brother.

The Number One Hero, Deku.

"Sorry I'm late," he says as he puts me down. He turns to Inventor and notices the three other heroes in his suit's giant hands.

He frowns.

"Stay clear, Eri," he tells me, "I'll be back in a sec!"

I do what he says and step back, just in time for him to leap into the air with incredible speed and power.

He allows his gloved hand to be surrounded by a spark of green lightening before reaching the giant suit.

Inventor panics.

"No! No! NO!" He yells in distress.

This is the moment.

"DETROIT…" Deku begins as his fist comes for impact, "…SMASH!"

With a powerful force, he punches it, blowing it up into several tiny parts and pieces. His allows the others to be set free of the robot's grip and land on the ground, with Creati in Shouto's arms.

Soon after, Inventor falls to the ground and my brother lands just next to the villain. As Inventor tries to crawl away, he's stopped by my brother who picks him up by the collar and dangles him in the air with one hand.

"It's over," My brother tells him, "Surrender peacefully."

A crowd of citizens slowly form and they all cheer.

The other heroes gather to my brother and sigh in relief.

"Thanks for coming, Deku." Creati says, "Things almost got out of hand."

"Things did get of hand, ribit." Froppy says, "But as usual nothing is too much for the Number One Hero."

My brother chuckles lightly, "It's not like I can't thank you guys," he says, "Thanks for keeping the citizens out of harm's way. Although," his voice becomes low as he raises an eyebrow in my direction, "What is Eri doing here?"

I flinch.

That's right. I'm supposed to be at home finishing my homework. Crap!

"She just popped out of nowhere," Creati admits with a nervous sweat.

"I think she just wanted to watch like she usual does," Froppy says next.

"She usually does this!?" The female heroines scream as my brother yells.

"What? No, that's not what we meant to say..." Creati says nervously.

"Hmm…" My brother hums unconvinced, turning to the only other male hero, "Shouto?"

"It's true," Shouto says calmly, "But either way she helped us out."

"She did?"

"Yup,"

My brother narrows his eyes, "How exactly?"

At that point, Shouto keeps quiet and looks in another direction. He then quickly checks his watch, "Oh look at the time. I'm going to be late for a meeting."

"Shouto. How exactly did Eri help?"

"Well bye."

"SHOUTO!"

I sweat drop. I really can't blame Shouto-niisan. If I were him, then I definitely wouldn't tell my protective older brother a.k.a the Number One Hero, that he purposely put me in danger so he would come and save me.

"Midoriya Eri!"

I flinch again as he calls my name. I slowly turn to face him and meet his angry eyes.

"Go home, feed the cat and do your homework!" Izu-niisan orders me after the police take Inventor to jail. He folds his arms and frowns at me. "And stop taking detours that could probably get you killed!"

I arch my head down as he scolds me.

"That's right Eri, be a good girl and go home," I hear Shouto say.

I pout.

"Yeah, and you be a good hero and don't use my little sister as bate!"

"But, we were like, going to die. And besides, it worked out didn't it?"

"Didn't you have a meeting to get to?"

"Oh right…"

"Liar! Next time come up with a better excuse!"

I sweat drop as my brother and his best friend argue. I guess I'll just go home now. Kurobaki is probably waiting for a refill anyway.

Yup, this was the everyday life of me, Eri.

A/N:

What did you guys think? It's just the first chapter so not too much humor. And I've decided that I'm going to write this in between updates for The Assassination of My Hero Academia! This is the story of a teenage Eri living a life that's always full of surprises along with her older brother, Izuku.

(I edited this, I made so many mistakes XD)
