eRr0r! (Vigilante Izuku Midoriya Story)

This is where things diverge a bit from canon, I hope you enjoy.

It was a crisp night, only a few days away from the training camp. Izuku—otherwise known as eRr0r!—leapt from rooftop to rooftop alongside his vigilante partner in crime, Hitoshi, also known as Mute! They'd patrolled together plenty of times by now. It was easier with Hitoshi around, even if they avoided using his Quirk unless absolutely necessary. They only used it in emergencies—to wipe the memory of witnesses if things got too close.

Tonight was like any other. So far, they'd caught five criminals since patrol began. The crime rate had dropped sharply in this area lately. Aizawa—Eraserhead—had been patrolling more often, probably in preparation for the camp since he wouldn't be able to keep watch during it. They'd run into him a few times, which had resulted in one very grumpy hero covered in glitter. It had been hilarious, especially since the glitter had clung to his hair and wouldn't come out. He'd shown up to school the next day still sparkling. They were almost through the entire rainbow by now. Next up was pink—it would definitely stick.

It was an ordinary night.

Until it wasn't.

A girl, no older than six, stood barefoot in the alley below them. Her hospital gown was soaked in blood. Bandages wrapped around her arms and legs like makeshift restraints. Her eyes were wide. Empty.

It was no longer an ordinary night.

Izuku's POV:

The night air was cool, fresh—nice, really. It had been a while since we'd had such good weather on patrol. Fewer criminals than usual, too. I should be relieved, right? But something about that... it feels like the calm before the storm. Like something's coming.

And I hate not knowing what.

Then I saw her, a young girl no older than 6, bandages and a gown, blood.

There is a million things wrong with this picture.

My boots hit the ground and Hitoshi landed beside me a beat later, smooth as ever. I didn't wait—I darted forward, hands raised like I was approaching a stray cat with trust issues.

"Hey there, tiny bean," I said, keeping my voice light. "Name's eRr0r!—we are here to help."

She flinched at my voice. Her eyes were wide, terrified, scanning for escape routes.

I slowed. Lowered myself to her eye level.

And that's when I saw it—the blood, the gauze, the shivering. The unmistakable signs of someone who'd been hurt. Badly.

"She looks like she came out of a horror movie," Hitoshi murmured behind me. "The real kind, not the budget kind."

"Yeah, well, welcome to tonight's feature film," I muttered. "Starring: Literal Child Trauma."

I took a breath. "Can you tell me your name, sweetheart?"

Her lips moved. A whisper. Barely audible.

"...Eri."

And just like that, the air went cold.

I froze. Hitoshi stiffened beside me.

Oh, we knew that name. 

We had recently interrogated one of Overhaul's men, one who had been apart of a certain project involving a little girl and quirk erasing bullets.

A girl with a rewind quirk. One locked up by Overhaul as some living science project.
