Accelerator Deku (bnha x a certain magical index)

chapter 1

Ever since Izuku turned 4 and was deemed quirkless, a loser, useless, and a deku, he slowly grew more and more apathetic towards others but still has a strong sense of justice.

We start when Izuku is 5 years old in the park, Izuku sees his childhood friend Kacchan bullying a girl who looked to be around their age.

"Kacchan stop it!" Midoriya was fed up with his antics.

"Or what? A quirkless nobody like you has no chance of winning against me!"

"This ends here, you will stop hurting this girl!"

She heard how he was quirkless... And yet he came to help even if he couldn't win. That lit a spark in her eye...

After a beat down from Bakugo, Izuku was on the ground battered and bruised. The girl was still there.

"Thank you, I'm Ochako Uraraka what's your name?"

Sitting up Izuku looked at her confused, no one had been kind to him since becoming quirkless, but it felt nice.

"I-Izuku Midoriya," he shyly responded

The he ran back to his house 'she shouldn't get involved with someone like me'

When he got home he ran passed a mirror. It was brief but he saw he didn't have green hair anymore... It was white.

Inko obviously noticed this change and took him to the doctor. After a few tests they concluded his quirk manifested... Vector Manipulation.

Time skip (because I'm lazy 😐)

It's been 8 years since Izuku helped Uraraka out of that situation, but hasn't seen her since. During that time Izuku has not only been learning physics but successfully managed to trick people into thinking his quirk is an intelligence boost.

Izuku is 13 years old now, taking the long way home because he doesn't want to be around bakugo. When he hears an explosion in the distance and decides to go check it out.

When he reaches the source of the explosion all he can do is let out a sigh.

Walking through the crowd and passed the useless heroes all Izuku says is "Can't you heroes take care of one hentai monster?" With a sigh.

You could hear some snickers from the crowd.

Izuku: Now I guess I'll just have to step in

Izuku then controls the vectors around his body to blitz toward the sludge villain, reaching his hand inside and making the villain explode.

Bakugo was free from his grasp but he wasn't happy that he was saved by the 'nerd' There were loud cheers from the crowd. Izuku left the scene before he could be questioned.

At the midoriya residence:

Izuku: Can I switch schools?

Inko nearly spit taking at her son's question

Inko: W-Why Izu?

Izuku: I used my power to save bakugo I just don't want to answer a bunch of questions

Inko: Okay, but you have to get at least one friend alright?

Izuku: *Sigh* "fine..."

A few days later at

Izuku was wandering the halls of his new middle school, lost.

???: Are you the new kid?

Izuku: *turns toward the voice* yeah, can you lead me to the office?

???: Sure *giggles*

On their way over...

Izuku: how've you been Uraraka?

Uraraka: how do you know my name?

Izuku: don't think I'd forget the first person who'd shown me kindness. Remember that day at the park, when we were little? You were getting bullied by bakugo, and me the late bloomer stepped in to try to help.

Uraraka: wait you're Izuku!? You said you were a late bloomer so what's your quirk?

Izuku: because I trust you I'll tell you... My quirk is called Vector Manipulation.

Uraraka was visibly confused.

Izuku: *chuckles seeing her face* you'll see it soon...
