Chapter Text
The op came down on a Tuesday, which was how Katsuki knew it was real. The fake ones came down on Fridays, when the agencies wanted a photo.
"Sagami rail yard," Aizawa said. He had the lights off and a map up and the general air of a man who had been awake since a time that no longer counted as the previous day. "Fencing operation running out of the container sidings. Stolen support gear, most of it ours, most of it from the reconstruction depots. Four agencies are running this and you are attached to Best Jeanist's team as the outer ring, which means you are a fence with legs. You do not enter the yard. You do not pursue into the yard."
"What if somebody comes out?" Kaminari said.
"Then you have accomplished the entire purpose of an outer ring." Aizawa dragged a hand down his face. "Third years," he called out, "this is a real operation with real paperwork. Anyone who improvises gets to explain it to a licensing board."
They went out at nine.
Katsuki drew the northeast corner with Kirishima and Uraraka, which was fine, and stood in the dark for two hours next to a chain-link fence, which was less fine but familiar. Rail yards at night had a specific kind of nothing to them. Sodium light, wet gravel, the long boredom of standing in the cold with your gear on and your heart rate too low to be useful.
At eleven-twenty the yard got loud.
Not gunfire or offense quirks. Noise, which was worse, because noise meant a plan had come apart somewhere. Katsuki heard shouting on the radio and three separate people talking over each other, and then Best Jeanist's voice, clipped, saying that the sidings were empty and the crates were empty and had been for hours.
"They moved it," Uraraka said, whipping around to them.
"They knew," Kirishima said.
And then, on the open channel, a voice that was not anybody's.
"Six of them are in the south drainage culvert. Two more went up the water tower stairs about ninety seconds ago and they're waiting for you to clear the yard before they come down." The voice was flat and low and came through a filter, the cheap kind that makes a person sound like a person underwater. "Your outer ring's got a gap at the southwest maintenance gate. It's been open the whole time. I'd fix that first."
The channel went completely silent.
"Who is this," Best Jeanist said.
"You've got about forty seconds on the culvert."
"Identify yourself."
"Thirty-five," the voice said, and clicked off.
Katsuki stood with his back against a fence post and felt every hair on his arms stand up.
They got the culvert. They got the water tower. They did not, at any point, get to the southwest maintenance gate before somebody else did, because when the sweep team arrived there were three men on the gravel with their hands zipped behind them and their inventory tags laid out on the ground in a row, sorted, Katsuki noticed, by depot number.
He knew before he came around the container line. He'd known since the radio.
Augur was crouched on the low roof of the switching hut, forty feet off, with one forearm on his knee, watching the sweep team work. He did not appear to be in any hurry about it.
Up close, or as close as Katsuki got, the suit was ugly in a way that made it obvious it wasn't a costume. Plate over dark fabric, matte, all of it scuffed to hell. Nothing on it was symmetrical. The left shoulder had been repaired and repaired again with a different grade of material each time, and there was a whole section along his ribs that had been cut out and replaced. The mask was blank except for a narrow band of optic that wasn't glowing, because he wasn't stupid.
He didn't look like a story or a myth or a rumor. He looked like equipment with a heartbeat.
"Hey," Uraraka said.
Katsuki turned his head so fast his neck hurt.
She had her hands up, palms open and flat in surrender. She'd taken two steps toward the hut, and her voice had gone into a register Katsuki had not heard out of her since they were sixteen.
"Hey. It's you, right?" She swallowed. "The, um, the north ring. The second night, during the war. You're the one who came down into the tunnel, the, the stairwell with the flashlight?"
Augur was quiet for a second.
"Third night," he said.
"Third night." Uraraka laughed, and it cracked in the middle. "Sorry. Third night."
"Your evac was good," Augur said. "You had four hundred people in a stairwell with no comms and you kept them from stacking at the bottom. That's the hard part. Most people can't do that. You're very brave."
"You told us the west door was compromised."
"It was."
"We'd have gone out the west door."
"I know," he said. "That's why I came down."
Katsuki looked around at his class.
Kirishima had gone completely still. Iida had his hand half up, like he'd started a formal address and lost the tail of it. Sero was staring. Even Shinsou, at the back, had his hood down.
Something knotted in Katsuki's chest and refused to be named. He had thought this was Kaminari's story. A doorbell camera and a nailed-up list and a guy who was probably short. He had filed it under rumor and left it there, and it turned out half his classmates had been in a stairwell in the dark with this man two years ago and had simply never said so out loud. Nobody talked about the war unless somebody made them.
"You were in the tunnels," Iida said.
"Some of them."
"There's no record of you."
"No," Augur agreed.
"Why not?"
"Because I wasn't licensed, I'm still not," he said, "and the people down there needed a route out more than the paperwork needed me to have permission." He shifted his weight, and Katsuki saw him do it, the left side move a half-beat behind the right. "You want the rest of it? Two of the men in the culvert are hired. They don't know anything and they'll say so in about an hour. The one with the yellow jacket has been running the depot numbers, he's the one worth your time, and he's got a second phone taped inside the lid of the green toolbox in the third container. Don't let him near the toolbox."
Best Jeanist said, from behind them all, "Come down and tell me yourself."
"No, thank you."
"Then you're leaving evidence at a scene and walking away from it."
"I'm leaving it with you," Augur said. "That's different, and you know it's different, or you'd have sent somebody up the ladder instead of letting my just run my mouth."
That was the first moment Katsuki heard anything in his voice at all, and what he heard was tiredness.
The yellow-jacket man made his move about nine seconds later.
He'd been sitting cuffed by the container line with two sidekicks on him, and he came up off the gravel fast. It turned out he had a friend nobody had counted, a big one, coming down the container row with a length of rail brake in both hands.
Katsuki was moving before the shouting started. So was Kirishima. So were four pros.
None of them got there first.
Augur came off the switching hut without a moment's hesitation, and Katsuki, who had spent his entire life around people who moved for a living, watched him cross thirty feet of gravel and could not find the moment where he thought about any of it. He didn't dodge the rail brake. He was standing where the rail brake wasn't, and he'd been standing there before it swung. He put a hand on the big man's wrist and turned it and the whole body followed the wrist down into the gravel. All of it was over and it had taken about a second and a half.
And underneath it, the whole time, he was talking.
Not to anybody. Low, fast, continuous, half swallowed by the filter, a running mutter of something that sounded like arithmetic. —left hand's dominant, he's set for the second swing already, don't take the arm take the wrist, watch the knee, he'll drop the knee—
Katsuki stopped where he was, about twelve feet out, with his palms already hot and nothing to use them on.
Something in his chest turned over.
He knew that. Not the man, not the suit, not the voice, the filter had that sanded down to nothing. The rhythm. That gabbling undertow of a person thinking out loud too fast for their mouth, running the problem in real time, not talking to you and not aware you can hear it.
He had heard that sound before. He was certain of it in the animal part of himself—the same part that had recognized a stillness in a doorway three weeks ago. He stood in a rail yard with his hands cooling and could not find where he had heard it. It sat about a half inch out of reach and stayed there.
Where do I know that from?
"Kats." Kirishima had a hand on his shoulder. "Hey. You good?"
"Yeah."
"You were making a face."
"I'm fucking fine."
By then Augur was already back at the edge of the container row and the sweep team was on the yellow-jacket man. Somebody had found the green toolbox and the phone taped inside the lid exactly where he said it would be.
He paused at the corner. He looked back, the blank band of his mask going along the line of them, the whole class, quickly, the same inventory Katsuki had watched happen in a workshop doorway and had not understood at the time.
It stopped on Katsuki. Half a second, maybe less.
"Ground Zero," Augur said.
Katsuki's body went to attention like a dog hearing its name.
"What."
"Your outer ring was fine." He said it evenly, without any weight on it. If it had come from anyone else, Katuski would have read it as condescension. "For what it's worth. The gap was on the plan, not on you."
And then he was gone around the containers. By the time Katsuki got to the corner there was nothing there but gravel and a service road and the sound of a train two yards over.
The debrief ran until one in the morning and consisted mostly of adults being angry in a small room.
Katsuki sat through it. He heard maybe a third of it. The word vigilante got used eleven times, and the phrase actionable intelligence got used four, and nobody seemed to notice they were describing the same person.
"He was in the tunnels," Uraraka said, on the bus back, to nobody in particular. She had her forehead on the window. "Nobody ever believed me about that."
"I believe you," Iida said.
"Everyone thinks I made him up. Even the debrief people, they always go, well, there were a lot of people moving in the dark that night. There weren't. There were four hundred civilians and a stairwell and one guy with a flashlight who knew which door was going to kill us."
"He knew the door," Kirishima said quietly, nodding.
"He knew the door."
Shinsou spoke up from three rows back, which he almost never did.
"How'd he know about the door?"
Nobody had an answer for that.
Katsuki looked out at the highway lights going past and thought about the man crossing thirty feet of gravel without a single wasted step, muttering arithmetic to himself, and about how the only two people he had ever met who could tell you what was going to happen before it happened were a man in a mask and a support student who wouldn't say good morning on a Wednesday.
The two facts sat in his head. He turned his face toward the window and would not let them touch.
Shinsou caught him in the dorm kitchen at half past one, which Katsuki did not appreciate, because he had come down specifically to be the only person awake.
"You didn't chase him."
Katsuki filled a glass. "No."
"You had a direct line. I watched you not take it." Shinsou got a mug out of the cabinet. It was teal and chipped on the top. "I'm not accusing you of anything. I'm interested."
"Then be interested somewhere else."
"Uraraka's been telling that stairwell story since second year," Shinsou said, ignoring him entirely. "I've heard it maybe six times. Every time, the guy with the flashlight knows which door is compromised, and every time, nobody asks the obvious question, because they're all busy being grateful."
Katsuki drank his water. "Which is fucking what, Eyebags?"
"How does a man with no discernible quirk and no license and no comms know that a door two floors up has been compromised?" Shinsou leaned back against the counter. "He didn't sense it. There's nothing to sense with that we wouldn't have already gotten. So he worked it out. From what, is the question. Sound, air, the numbers coming down the other stairwell, something. He was doing that math in a war zone in the dark and he got it right the first time. If he'd gotten it wrong, four hundred people go out the west door. Four hundred people die."
"So?"
"So everybody keeps calling him a ghost." Shinsou poured his tea. "He's not a ghost. He's a person with a method. Methods come from somewhere. Somebody built that, or he built it himself over a lot of years, and either way there's a paper trail somewhere in this country with a very strange kid at the start of it."
Katsuki set his glass down harder than he meant to.
"You always talk this much at one in the morning?"
"Only when something doesn't add up." Shinsou looked at him over the mug, mild as milk. "He knew your hero name."
"Everybody knows my hero name."
"He knew the plan gapped at the southwest gate and he knew it wasn't your fault. He went out of his way, mid-exit, to tell you so." Shinsou shrugged and pushed off the counter. "That's a weird thing to stop and do. That's all. Night, Bakugou."
Katsuki stood alone in the kitchen for a long time after he left, with the fridge humming and a glass of water going warm in his hand.
In the morning Izuku was careful.
That was the only word for it. Katsuki got to the workshop at six-fifty because he always did now, and at seven-oh-two the door opened, and everything about the next ten minutes was correct in a manner that made Katsuki's teeth itch.
Coffee, right hand, set down at the far corner, logo to the wall. Calipers. Drivers. Forty minutes of small clean sounds. He wasn't limping. He wasn't favoring anything. He moved like a man who had spent the previous night asleep in a bed. He did it so well that Katsuki, watching sideways with a equipment in his hand, would have believed it completely if he hadn't spent two years learning what people looked like when they'd decided in advance not to wince.
There was a scrape on the back of his left hand, cleaned and closed and about the size of a grain of rice.
"You're up early," Izuku said.
"I'm always up early."
"You're up earlier." He didn't look over. "Six-forty-something. Your bag was here before the lights came on."
"Big op last night."
"I heard." He turned something a quarter and checked it. "Sagami yard. Sounds like it went sideways."
"Who told you that."
"Iida," Izuku said. "At seven this morning, at full volume in the corridor, to Yaoyorozu. I'd guess about forty people know by now."
Katsuki grunted. That was, unfortunately, exactly how Iida distributed information.
The compressor kicked on and ran and shut off. Outside, the sky was getting pink.
"They had a vigilante out there," Katsuki said.
It came out of him without a plan attached. He didn't look up while he said it. He kept his eyes on a screw and turned it over in his hands and listened, very carefully, to the far end of the bench.
The small clean sounds continued without a hitch in them anywhere.
"That happens," Izuku said.
"You don't want to know which one?"
"I assume it was the one everybody's excited about."
"Half my class knew him." Katsuki set the housing down. "From the war. Uraraka's been telling people about a guy in a stairwell for years and nobody believed her. Last night he stood on a roof and told her which night it was, and she just about lost it."
Izuku's hands kept moving.
"That's good," he said. "That she got it confirmed. People carry that stuff around for a long time when nobody confirms it."
"You think?"
"I know." He set a piece down and picked up the next one. "It's worse when it's a rescue. You spend a couple years wondering if you invented the person who got you out, because if you invented him then the whole night gets a little more unbearable, since it means nobody came."
Katsuki looked up.
Izuku wasn't looking at him. He was doing something to a joint housing with a driver, entirely absorbed, and there was nothing in his face except mild attention to his own hands.
"He was fine," Katsuki said. "The outer ring gapped at the southwest gate. Wasn't on us, I guess, it was a bad plan, but he called it out over an open channel before anybody else even had it." He felt like he was rambling at this point.
"Then it sounds like he was paying attention."
"Yeah." Katsuki's mouth was dry. "Yeah, he was paying attention."
He watched the light come up across the bench, and the small scrape on the back of a hand, and he had a sentence in his head that he could not make himself say, which was: you talk like him.
He didn't say it. He didn't say it because it was insane, and because Deku had never in his life been able to keep a secret for six seconds, and because a person who built joint assemblies and got winded on stairs at fourteen did not cross thirty feet of gravel without a wasted step, and because the alternative required Katsuki to have been wrong about a person for ten straight years, which was not a thing he was prepared to be at seven in the morning.
"Bakugou."
He blinked. "What."
"You've been holding that housing for four minutes," Izuku said, and now he was looking over, with that small locked corner-of-the-mouth thing, gentler than usual. "It's fine. It was fine when you picked it up."
"Mind your business."
"Sure." He turned back around. "Get some sleep sometime. You look like hell."
"You look like hell."
"I do," Izuku agreed. "Ladder."
And Katsuki laughed, once, before he could stop it, ugly and surprised, out loud in an empty workshop at seven-thirty in the morning. Across the room he saw Izuku's shoulders move, just slightly, and he didn't turn around. Neither of them said anything about it.
The rest of the morning went by. Katsuki got the plates seated into the grooves. Izuku left for class at seven-forty-five, and Katsuki sat there afterward in a room that had gone quiet in a manner he was beginning to dread.
The silence gave him too much time to think and right now he thought about a scrape the size of a grain of rice, and muttering into a filter, and a voice on an open channel saying I'd fix that first.
He got right up to the edge of it.
Then he thought about the pond, and about ten years of getting a person wrong, and he stood up and put his tools away and went to class. He did not turn around on this thing he stood at the edge of, because if he'd turned around he would have had to know.
