Nox measured the morning by what he would have to survive, not by the numbers on the clock. The walk to his desk in the back row was thirty steps, and every one of them had eyes on it.
His uniform was clean and still ruined, scrubbed raw at the sink each night without ever coming back to blue. The stains had gone into the weave years ago and stopped answering to soap or effort.
Somewhere in those years, the part of him that used to flinch had shut off for good. It had not healed so much as closed, like a door he had stopped trying to open. The quiet made mornings easier, the only mercy he expected from this place.
He sat down, tucking his bag against his shin where the shape and weight of it stayed close. Ms. Joy read attendance at the front, her voice sliding over his name without once stopping on it.
"Smells like he slept in a bin again," a boy two rows over said, loud enough to reach the back.
The girl beside him laughed on cue, the bright sound of a person who wanted to be counted on the safe side. Across the aisle a heavier student found something urgent in his notebook and kept his head down.
One girl near the window watched Nox instead of the joke, and whatever she read in his stillness kept her quiet.
Mark came down the aisle with a cup in his hand and the smile he wore like a standing permit. He had made a performance of Nox for years, and the room had learned to wait for it.
"Careful," Mark said, and tipped the orange drink down the front of Nox's shirt without breaking stride.
The cold soaked through the fabric to his stomach while the laughter came up easy and pleased with itself. It was permission, and the room took it, because someone with standing had shown them the joke was safe.
Nox raised his hand a few inches, the smallest motion the room would take from him without fresh laughter.
"He poured that on me, Ms. Joy," he said, keeping his voice level enough to pass for calm.
She looked at Mark, then at the cup, then back down to the papers she had decided were the greater problem.
"I'll talk to him after class. Go clean yourself up, Nox," she said, without lifting her eyes from the desk.
Mark's smile widened as he leaned back against a neighboring desk to watch.
"You heard her, so go clean up," he said, tipping his chin toward the door.
The laughter settled back into the ordinary noise of a room that had moved past him already. He stayed where he was and understood something with a clarity that felt almost restful in his chest.
Nobody in this building was going to stop it, because nobody in it had ever once meant to. If it stopped, then he would be the one who stopped it, and the thought arrived without heat or noise.
He reached into the bag against his leg, and the few students near enough to see the care in the motion went still before they understood it. The gun had been a decision made days ago, carried in every morning since without a plan for the hour.
He drew the gun out of the bag and set his hand around it on the surface of the desk. The metal was cool under his fingers, and heavier than it looked resting there in plain view.
The silence spread outward from him in a ring until it reached the front wall. Mark's smile came apart piece by piece, and Ms. Joy's hands went quiet over her papers.
"Put it down, Nox," she said, using his name now with a speed and care she had never once spent on helping him.
He gave her nothing back, and looked at their faces one at a time until he found the thing he had wanted to see there for years. It was fear, and it changed nothing that mattered, but it meant they were paying attention to him at last.
He lifted the weapon, but before the barrel could settle on a target, a screen opened across his sightline in a pale blue light only he could see.
[ Requirements met. ]
[ First Player selected. ]
Nox stopped with the gun half-raised and the words hanging where a face should have been. None of it meant anything to him yet, and the meaning could wait behind the older arithmetic of the room.
The gun stayed in his hand, and the screen had bought everyone a second, but a second changed nothing about the people in front of him.
The class saw a boy pointing a weapon at empty air and freezing there, staring at nothing they could find. A few of them started to plead in low and shapeless voices, afraid that any clear word might set him off.
Then the floor moved, not shaking so much as tearing along a seam that opened up the length of the room. Desks slid toward the new low point while a crack climbed the wall beside the door and kept going.
Through the windows the skyline bent out of true, and towers he had never seen pushed up between the familiar ones. Mark had gone down flat between two desks with his arms over his head. Whatever the world was doing, it had at least interrupted him mid-smile.
Nox caught the metal window frame with his free hand and held on while the building bucked under him. Students who had waited all morning for an adult to fix things crawled between the falling shelves and found no one there.
The motion went on far past reason, minutes stacking toward an hour, until it wore itself out and left the room breathing grit.
New lines printed themselves onto the screen while the last of the tremors died out under his feet. He read them without letting go of the frame, in case the floor decided to move again.
[ Merge complete. ]
[ Current population: 20 billion. ]
[ Mana injected into the atmosphere. ]
[ Dungeons placed across every territory. ]
[ Good luck, Player Nox. ]
The number said twenty billion, when the Earth he had grown up on had carried eight. He read it twice before the wrecked room refused to let him call it a fever or a trick of nerves.
Light drained out of the screen as it winked shut, while Ms. Joy dragged herself from under her desk with grime across her face. Whatever authority she had carried into the morning had gone out with her balance.
"It's him, he pulled that thing out and the whole world started shaking," Mark said from behind the three desks he had shoved into the aisle.
"Don't be stupid, Mark," she said, but her eyes stayed on Nox the whole time, and something under the words wanted the accusation to be true so the danger would finally have a name.
Nox let the two of them talk over each other without stepping in. The number still sat behind his eyes, holding more of him than anything either could say. Their voices had never shaped one thing in his favor, and they would not start now.
A scream came from the hallway, high and short, cut off before it had the room's full attention. Every head in the space turned toward the classroom door at once.
A wet weight struck the glass in the classroom door from the far side and slid down it slowly. The smear it left behind was the color of meat, and no one moved to explain it.
"Nobody opens that door," she said, though the order had nothing behind it to make anyone obey.
A new screen opened in the air in front of Nox and no one else. The others were still staring at the door, so the blue light stayed his alone.
[ Mission: Clear the dungeon within your school. ]
[ Reward: 1,000 EXP. ]
[ Reward: one random skill. ]
[ Reward: 5 stat points. ]
[ Accept? Y / N ]
He read it through with the gun still warm against his palm. An hour ago the only exit he could find ran through this room, then through himself. The screen changed the shape of the way out, not the person taking it.
The screen was holding open a different door, and behind it sat something he had never been allowed to have. The deadness in him did not lift at the sight of it, but something shifted underneath, closer to hunger than to hope.
He looked down at the gun again and let the plan for the class fall away from it. Maybe the weapon was not for them anymore, and maybe it was meant for whatever had left that smear on the glass.
Nox fixed his focus on the Y and held it there until the System accepted the choice as final.
[ Mission accepted. ]
The screen cleared just as a heavy blow landed on the door from the hallway side. Wood split around the handle, and a low wet growl came through the gap it had opened.
Mark took a single step closer over the shifted floor, both hands lifting toward Nox. The old confidence was gone from him, replaced by the plain need of a person who wanted a way out.
"Give me the gun, Nox, it's the only one that works," he said, with his voice climbing toward a break.
The door burst inward off its hinges, and a hunched grey-skinned shape shouldered through the broken frame, hunting for the nearest warm body it could reach.
