The stairs were wide and cracked and went down toward the plaza in long flat sections.
Izuku walked down them.
Behind him, the Ruin Zone was quiet. The kind of quiet that happens after something is finished being loud.
He pulled the Hound back without breaking stride. Felt it compress and fold into the shadow at his feet. The resistance was there again. That slight drag, the half-second delay before it obeyed. Like pulling a dog away from food it wasn't done eating.
'We're going to have a conversation about that later.'
Below him, the plaza was a mess.
The water from the fountain was displaced. The concrete had cracked in rings from the portal breach. And at the center of it, the Nomu was kneeling over something that had, until recently, been standing up.
Aizawa was on the ground.
The Nomu had both hands on him.
What was happening to him was slow.
Izuku kept walking.
He didn't run. Running was information. Running said "I'm scared" and "I'm reacting" and "I've lost control of the situation." Walking down a flight of stairs toward a bioengineered killing machine said something else entirely.
Whether that something was courage or stupidity was a question for later.
His mana read the Nomu the same way it had from the observation point. The signal came back wrong. Dead matter forced into motion. The frequency of something that had been dragged back across a threshold it had already crossed.
'That's not a monster. Monsters are alive.'
The Nomu was a body. Or several bodies. His mana couldn't distinguish the seams from this distance. Packed with quirk factors the way you'd pack a machine with stolen parts. Every component grafted without care for what the original architecture had been. The flesh held together because something external was forcing it to hold together. The motion continued because something external refused to let it stop.
'Someone took a person apart and used the pieces as building materials.'
The disgust hit him in the chest. Cold. Certain. The mana recognized what had been done to this thing the way an immune system recognizes a disease. Whatever process had made the Nomu, it was a violation of everything the Shadow Monarch's power was built on.
His shadows followed rules. There was an architecture. A logic. A respect for the threshold between alive and dead.
This thing had no respect for anything.
'Stolen parts. Moving because someone told them to. That thing was a person once.'
He was three-quarters down the stairs when he saw Shigaraki move.
The pale figure had drifted toward the water's edge. One hand extended. Fingers spread wide, reaching for a face.
Tsuyu was there. Half-submerged. Eyes wide. Still.
Izuku didn't shout.
He grabbed the stair rail with his left hand and tore a chunk of concrete free from where the mounting had already cracked. Fist-sized. Heavy enough.
He set his feet. Triggered the accelerometer.
And punched the concrete like it owed him money.
The gauntlet fired on contact. The discharge transferred straight through the rock. A kinetic shockwave compressed into a single object moving very fast in one direction.
The chunk hit Shigaraki's extended hand.
The crack echoed off every surface in the dome and came back from three directions at once. Shigaraki's arm whipped backward. His body followed. Two staggered steps, then down on one knee, the other hand slapping concrete to catch himself.
Tsuyu wasn't touched.
Charge indicator: 32%.
'That'll have to be enough.'
Izuku stepped off the last stair onto the plaza floor.
Shigaraki was already recovering. Scratching at his neck with both hands now. Fast. Frantic. Fingers dragging red lines across the skin.
"What — you're a — you interrupted — you're a student, you interrupted me, you actually—"
His voice was cracking. Not with fear. With the frustrated disbelief of someone whose video game had just glitched in the middle of a cutscene.
'This guy's not stable. Like, clinically not stable. Someone gave a Nomu to a man who is actively falling apart.'
Izuku did not look at him.
He looked at the Nomu.
He walked toward it.
And he stopped holding back.
The mana came up without being forced. It had been sitting just below the surface the whole descent, contained by decision, not effort. He let the decision go.
The temperature in the central plaza dropped.
The air shifted. Pressure first. Then cold. Then a heaviness that made breathing feel like a conscious choice.
Breath fogged. His first. Then Tsuyu's. Then Shigaraki's, still mid-sentence when the fog appeared in front of his mouth and shut him up more effectively than a punch would have.
The wet concrete at the plaza edges began to frost. The surface whitening at the cracks.
The Nomu didn't shudder. It had no apparatus for that. But its motion hitched. One beat. Less than a second. A process encountering an input it was not built to handle.
Something in the dead tissue had registered the pressure. A raw biological remnant of something that had once been alive, reacting to a signal older than thought.
'You felt that, didn't you. Whatever's left of you in there. You felt me.'
Aizawa was on the ground three meters away. Capture weapon gone. Goggles cracked. One arm at the wrong angle. Still conscious. Barely. Each breath a decision being made on resources that were running out.
His eyes found Izuku.
The kid from the exam. No quirk on the application. Sixty points in nine minutes. The shadow Aizawa had been watching since day one. The thing his Erasure couldn't touch.
The kid was walking toward the Nomu.
Calmly.
Like he was crossing a room to close a window.
Aizawa's mouth moved. No sound came out.
Izuku stopped two meters from the Nomu.
The thing's eyes, whatever they were, rotated toward him. He looked up at it. Eight feet tall. Stitched together. Dead and moving and wrong in every way a thing could be wrong.
His chest was cold. The plaza was cold. The air itself felt heavy, thick, like the space between them had opinions about what was about to happen.
He spoke.
One word. Flat. Dead. The word he'd said to a fish in a koi pond ten months ago, the word that had started everything.
"Down."
