Work Text:
It had started out like any other day, and honestly he shouldn’t be surprised by that considering every stupid situation he’d ever landed himself in had started with a normal day.
Izuku’s mother had asked him to come home for the weekend, she’d needed help moving some things around the house and he’d been all too happy to offer his strength to her on his off time from school. He’d also missed the sweet sunshine woman, with everything going on with his hero courses, he’d been so drained he’d spent most of his free time sleeping or writing in his hero journals to wind down. He had also taken up sparring with Kaachan and Kirishima-kun most Sundays to help him adjust to his quirks.
Frustration curled in the pit of his stomach at the thought of the sparring sessions. He’d been working so hard, and practicing so much, but it seemed no matter what he did, he just couldn’t beat Kaachan. It didn’t seem to matter that he’d been training with Allmight, or that Mirio had even taken to working with him whenever he had the free time, it was like he just wasn’t going anywhere.
He’s always going to be stronger than me… When will I catch up? The bitter feeling had been getting worse lately, and he wasn't sure if it was aimed at himself or Kaachan anymore. He'd sighed in exasperation, head down as he waited for the train to come to a full stop, glancing up when the automated voice announced the doors would be opening. He stepped out, hiking his bag further up his shoulder and jerking in mild surprise as a weight smacked into his legs.
Automatically he'd tensed, his first reaction to go into defense mode until he noticed the small child at his legs rubbing their nose to quell the sting of the impact.
“Oh! Uhm, sorry! I didn’t-“
Surprise shot his eyebrows up into his hairline as the small brown haired girl had looked up at him with miscolored eyes. In a world of quirks, it honestly wasn't unusual to see someone with what might've once been considered some sort of unnatural mutation in their eyes (Mina was a good example of that, her eyes still unnerved him sometimes) but there was something… different about these. It wasn't unnerving per se, but the feeling that had settled in the pit of his stomach hadn't been pleasant either.
The girls left eye was completely encompassed in a inky black except for the bright glowing red pupil, and her right was the exact opposite. At least, that’s what he thought, but with a blink it seemed to switch, Izuku's brows pinching in confusion. Vaguely, he wondered what type of quirk could cause such a strange coloration.
In the very next moment the girl was gone, a frown pulling at Izuku’s lips as he watched her scurry through the legs of passengers and disappear onto the train just as the doors slid shut with finality.
Huh.. weird.
That had been the only thing he’d thought of the whole ordeal until he’d finally gotten back onto school grounds.
The headache had hit him with such a sudden and powerful force that he’d staggered, stomach rolling with the threat of spilling its contents onto the pavement outside of Heights Alliance. God he was going to be sick.
“Midobro!”
Kirishima’s voice sounded as if it was coming through a filter, echoing in his ears with a dizzying effect.
“Uhh… dude? You okay? You don’t look so hot.”
A heavy hand had fallen on his shoulder, steadying him before he pitched over. Kirishima’s face was pinched in concern, or rather, it might’ve been. It was a little hard to tell when his skull felt as if it was going to split itself down the middle.
“I uh… I think I need to go lie down.”
Kirishima had been kind enough to help him to his room, getting him situated in bed after asking him yet again if he was sure he didn’t want to go to Recovery Girl. Part of him had wanted to say yes, worrying that maybe an old injury was acting up or if he was having some type of random brain bleed, but if he came to that poor woman with yet another unexplainable injury, she was probably going to put him in the grave herself.
“I’m okay, Kirishima-kun. I think I just need to rest.”
Famous last words of course.
Kirishima had left reluctantly, doing a not-so-covert once over of him to make sure he wasn't visibly injured somewhere, and Izuku had curled up into himself in an attempt to sleep whatever this feeling was off. Maybe he’d feel better in the morning.
Izuku blinked his eyes open, staring dazedly at the large full length mirror positioned in front of him. Why was there a mirror here? Actually… where was ‘here’ to begin with?
From what he could see, he was in a bright white space of some sort that extended infinitely in all the directions in his sight. It vaguely reminded him of the dark area he visited when speaking to the vestiges of All for one, but that couldn't be what this was. How had he gotten here? Hadn’t he gone to sleep? Was this a dream then?
Movement in the mirror drew his focus back to it, adrenaline spiking as he stared at… himself?
The Izuku in the mirror stared back at him with eyes that glowed the color of toxic waste, much like his own when All for one was active, but the electric green color encompassed the entirety of his eyes, leaving no pupils or irises to be seen. The gaze left him feeling off kilter, his skin crawling with discomfort.
Mirror Izuku seemed to be in a space similar to his own, but entirely black save for a single white off in the distance.
What was this?
Izuku tried to move, panic setting in as he realized he couldn’t, his body not responding to him at all. Was this really a dream or had something happened? Had he been attacked in his sleep? Was this a quirk?
The Izuku in the mirror stepped closer, expression blank minus the predatory focus of his eyes. Those eyes cut into Izuku like a knife, dissecting him piece by piece until he felt entirely too exposed. His breathing picked up, feeling that odd headache forming at the base of his skull and spreading upwards until his vision was tunneled and all he could see was Mirror Izuku as the other him raised a hand to the glass and gave a slow smile.
A single crooked finger touched the other side of the glass and it cracked in two, splitting Izuku down the middle right along with it.
Vibrant, toxic viridian orbs opened slowly, staring up at the ceiling of his… their.. dorm room for a moment. Deku sat up with a languid ease, cracking the bones in his neck and taking a deep breath of the fresh night air. It felt so good to be awake.
A quick glance to his left revealed the unconscious and whimpering form of Izuku, the green haired male curled into a ball on his side of the bed.
Deku rolled his eyes, looking down at his hands and flexing his fingers experimentally. The webs of energy granted by one for all spiderwebbed across his skin in a vibrant array of color before shifting to a darker, almost black tinted green.
A slow, predatory smirk curled his lips. Oh he was going to have so much fun.
