The arm was the first thing they saw.
Izuku walked into Class 1-A two days after the USJ attack wearing his uniform jacket with the right sleeve rolled to the elbow because the fabric irritated the grey skin and he'd decided that hiding it was more effort than he wanted to spend on people's feelings.
The room went quiet. Not the sharp, sudden quiet of the Battle Trial. A slower thing. Conversations winding down as heads turned and eyes found the arm and stayed there.
Grey from fingertip to elbow. The veins visible underneath, dark lines like someone had drawn a road map on him in ink that didn't wash off. The fingers moved fine. Mostly. Half a second of delay if he wasn't concentrating.
He walked to his seat in the back corner. Sat down. Put his headphones around his neck.
'Twenty seconds before someone says something. Taking bets.'
Fourteen seconds.
"Midoriya." Kirishima. Standing up from his seat, turning around, face doing that thing it did where he was clearly concerned but also trying to figure out if concern was the right move or if it would get him killed. "Your arm, man. Is that — are you okay?"
"It works," Izuku said.
"But it's —"
"Grey. Yeah. I noticed."
Kirishima opened his mouth. Closed it. Sat back down.
Kaminari was staring openly. Sero was pretending not to stare, which was worse. Bakugou was looking out the window with the concentrated intensity of a man who was absolutely not looking at Izuku's arm.
Across the room, Uraraka glanced at him. Her eyes went to the arm, then away. Too fast. The way you look away from a car accident when you realize you know the driver.
Izuku pulled out his phone.
'Fourteen seconds. Kirishima. Should've guessed. That guy has the emotional intelligence of a golden retriever and the self-preservation instincts to match.'
Although. He was the only one who'd actually asked. Everyone else was staring or pretending not to. Kirishima walked up and said the thing out loud. That took something, in a room where the rest of the class was treating Izuku like a grenade with the pin halfway out.
'Noted. The good kind of noted.'
Someone sat down in the empty seat next to him.
He looked up.
Tokoyami Fumikage. Dark Shadow's host. Bird-headed, quiet, someone who naturally occupied corners and shadows the way Izuku did. He'd been sitting three rows ahead all semester. This was the first time he'd moved.
He didn't say anything. Just sat down, pulled out a notebook, and started writing.
Dark Shadow peeked out from behind his shoulder. The living shadow quirk — sentient, chatty, bound to Tokoyami the way the Hound was bound to Izuku.
It looked at Izuku.
Then it flinched.
A visible, full-body flinch, pulling back behind Tokoyami's collar like a dog that had just smelled something it didn't understand. Tokoyami's pen paused. He glanced sideways at his own shadow.
Then he glanced at Izuku.
Izuku had felt it too. The Hound — barely back, barely a presence, more like a pilot light than a flame — had stirred when Dark Shadow looked at them. Not aggressive. Not threatened. Something else. Recognition, maybe. The way two animals from different species notice each other across a room and decide whether the other one is food or family.
'Your shadow just flinched at my shadow.'
He looked at Tokoyami.
Tokoyami looked back.
Neither of them said anything.
'Okay. This is going to be a thing.'
Tokoyami went back to writing. Izuku went back to his phone. Dark Shadow stayed hidden behind Tokoyami's collar, occasionally peeking out and then retreating.
The Hound pulsed once at Izuku's feet. Faint. Curious.
'Behave.'
***
Aizawa came to class in a wheelchair.
Both arms in casts. Face wrapped in bandages that left only his eyes visible. Those eyes were the same as always — flat, tired, and completely unwilling to pretend that any of this was fine.
He rolled himself to the front of the room. The class was silent. The kind of silent where twenty teenagers were simultaneously discovering that their homeroom teacher had gotten the shit beaten out of him two days ago and was back at work anyway.
"I look worse than I feel," he said. "Which is still bad. Don't ask about it."
Nobody asked about it.
"Two announcements. First: the USJ incident is under investigation. You will be contacted individually for statements. Answer honestly. Don't embellish. If you didn't see something, say you didn't see it."
His eyes swept the room.
Found Izuku.
Stayed for exactly one second longer than they stayed on anyone else.
Izuku looked back. The man's arms were broken. His face was held together with bandages. The same creature that had done that to him had done this to Izuku's arm. They'd both fought the Nomu and they'd both lost something to it.
Neither of them said a word about it. Neither of them needed to.
"Second: the U.A. Sports Festival is in two weeks."
The room erupted.
Not all at once. A chain reaction. Kirishima saying "hell yeah" too loud. Kaminari already talking about strategy. Mina bouncing in her seat. The energy shifting from post-trauma quiet to competitive excitement in about four seconds.
Izuku didn't react.
He was thinking.
'Sports Festival. National television. Every pro hero in the country watching. Every villain too.'
He looked at his grey arm.
'The League saw what I did at USJ. Shigaraki saw the Hound. Saw the cold. If I use the shadows on national TV, every villain in Japan knows exactly what I am and what I can do.'
He flexed his grey fingers under the desk. The delay was still there. Half a second. Consistent.
'Gauntlets only. No shadows. No mana. No Hound.'
The decision was cold and immediate. Not because he didn't want to use the power. Because using it on camera was handing the League of Villains a tactical briefing on his capabilities wrapped in a highlight reel.
'They want to see what I can do? Fine. I'll show them the gauntlet. The fists. The conditioning. The thing they can prepare for.'
'The shadows stay in the dark where they belong.'
He looked at Tokoyami. The bird-headed boy was writing something in his notebook with the calm focus of someone who'd already been thinking about the festival before the announcement.
Dark Shadow peeked out again. Looked at Izuku. Didn't flinch this time.
Progress.
Izuku looked at the desk.
Under his feet, the Hound pulsed. Stronger than this morning. A little warmer. A little more present.
Coming back.
'Two weeks,' he told it. 'Stay quiet for two weeks. I'll handle this one without you.'
The cold didn't settle.
It pushed back. A pressure behind his sternum, sudden and sharp, like the Hound had heard the order and decided it had opinions about it. His breath caught. His grey hand twitched under the desk.
'I said stay quiet.'
The pressure held for two seconds. Three.
Then it released. Slowly. Like something unclenching a jaw it hadn't wanted to unclench.
The cold settled. Patient.
But not cooperative. Not agreeing. Just... waiting.
For now.
