"Welp...time to earn my bonus." Wolfram calmly joked as he relaxed into it...the endless stream of power and really kicked things off.
Among the tired eyes of Iida and Midoriya...metal slowly flew up, to form a mass of shrapnel, steel and whatever else above them. Then it fell. Fast. "Watch out~" Wolfram mockingly warned.
Time slowed.
Not for Wolfram. Not for the falling metal.
For Tenya Iida.
The world narrowed into vectors and calculations—angles of descent, velocity, mass, the way air screamed as countless fragments of sharpened alloy fell like a man-made meteor shower. His engines roared hotter than they ever had before, the sound no longer a clean mechanical whine but a howl, strained and feral, like something alive being pushed past its limits.
Eight seconds.
That was all.
Wolfram hovered above them, framed by collapsing metal, orange light pulsing beneath his skin as if something inside him was burning to escape. The device around his head thrummed, veins of energy branching outward. Multiple quirks. Boosted. Overclocked. Abused.
A monster wearing a man's confidence.
Iida didn't look at him.
He looked at Midoriya.
Izuku stood at the edge of collapse—knees bent, breathing ragged, green lightning flickering weakly instead of roaring. His fingers clenched around Denki, whose head lolled uselessly against his shoulder, sparks gone, consciousness stolen by his own bravery.
Iida's voice came out steady. Too steady.
"Midoriya… you can regroup with the others."
Izuku froze. "Iida—no, we can still—"
One look.
That was all it took.
Not fear.Not despair.
Resolve.
The kind that doesn't ask permission.
The kind that says this is already decided.
Izuku swallowed hard. His mouth opened, then closed. His hands tightened around Denki as One For All flared again, forced, imperfect, but enough.
"…I'll come back," Izuku said, voice breaking despite himself. "I swear."
Iida smiled.
Small. Real.
"I know."
Izuku turned and ran.
Wolfram noticed immediately. His grin widened. "Ooh? A classic sacrifice? How touching. But really, kids—"
The metal block burst.
The rain began.
Shrapnel fell in every direction, each fragment accelerated, guided, hungry. The air became a killing field—no safe path, no blind spot.
Iida inhaled once.
Deep.
Focused.
"RECIPRO… OVERDRIVE!"
The engines on his calves ignited—not blue, not white—but red, glowing like molten steel. The sound cracked the air, a thunderclap that bent the arena's metal rim inward.
He vanished.
Not ran.
Not dashed.
Vanished.
A single crimson streak carved through the storm, Iida's body moving faster than thought, faster than instinct. His kicks weren't attacks anymore—they were erasures, each impact detonating fragments into harmless dust before they could reach Izuku's retreating form.
Metal struck his legs.
His arms.
His back.
Each impact screamed through his bones, sparks bursting from his armour as friction tore at him. His suit burned. His muscles swelled painfully, veins standing out as if they might rupture.
Six seconds.
His engines screamed louder, heat blooming through his lower body, pain finally catching up to speed.
Wolfram's eyes widened—not in fear, but surprise.
"…Hah," he muttered. "You're serious."
Another wave came.
Heavier.
Denser.
Iida leaned into it.
He planted his foot mid-sprint and pivoted, redirecting his momentum in a perfect arc, intercepting the densest cluster head-on. His leg struck—
—and something cracked.
Pain exploded up his spine.
But the metal shattered.
Five seconds.
Izuku reached the arena's edge. He jumped—green lightning flaring as he launched outward, Denki clutched tight, disappearing into open air below where allies waited.
Safe.
Iida didn't look back.
He couldn't afford to.
Four seconds.
The rain thinned—but Wolfram raised his hand again, metal surging, preparing another wave.
"Persistent little bug," Wolfram said, irritation finally bleeding into his tone. "Fine. I'll crush you first."
The arena tilted.
Iida felt gravity shift violently as the floor tried to fold him inward.
Three seconds.
His engines were screaming now—not just sound, but sensation, a burning agony that tore through his legs. Smoke poured from his calves. Warning lights flashed uselessly inside his suit.
He pushed harder.
Just a little more.
Two seconds.
The metal storm ceased.
For a heartbeat, there was silence.
Iida skidded to a stop at the center of the arena, feet digging trenches into the metal floor. Steam poured off him in waves. His breathing was harsh, uneven.
He stood.
Barely.
Wolfram descended slowly, boots touching down a few meters away, metal coiling lazily around him. "You bought them time," he said, almost kindly. "That's something, I suppose."
One second.
Iida straightened as much as he could, legs trembling violently now. His engines glowed white-hot, cracks spiderwebbing along the casing.
"My duty…" he said, voice strained but unbroken, "…is to ensure my classmates' safety."
Zero.
A horrific shriek echoed as both engines seized.
The glow vanished.
Smoke billowed.
Iida collapsed to one knee, hands slamming into the ground to keep himself upright as the pain finally crashed down in full.
Wolfram stepped forward.
And then—
BOOM.
The arena shook.
Not from metal.
From impact.
A familiar, overwhelming pressure slammed into the battlefield like the arrival of a living force of nature. The air itself seemed to recoil.
Wolfram's head snapped up.
"…Oh?" he said softly.
A shadow fell over them both.
Golden light cut through the smoke.
A massive figure landed between Wolfram and Iida, the metal floor buckling beneath his feet.
"I AM HERE."
All Might straightened to his full, impossible height, cape snapping behind him, eyes burning with righteous fury as he looked down at the villain.
"And you," he continued, voice dropping into something dangerous, "have pushed my students far enough."
Behind him, Iida looked up—exhausted, broken, but conscious.
"…A-All Might—"
All Might didn't turn.
But his voice softened, just slightly.
"You did splendidly, Young Iida."
Wolfram laughed—low, excited, thrilled.
"…Now this," he said, metal rising around him eagerly, "is worth the paycheck."

[Auther: All Carry has about 3 hours of buff mode, right? Let's assume that he has hours of buff mode if he's in constant combat. Thus, during the plane ride, he wasn't actually buff the entire time, just entering and exiting. Thus, during his time walking around in the day(Roughly an hour at best), he relaxed when chatting with David, then rested till the party. During the capture of Pro Heroes, he was in buff mode for at least an hour; there's no way the main cast could scale almost 200 floors before an hour.
Btw, combat with the USJ Nomu is life-threatening combat, so it actually shortens his time. Thus, I can calmly say, All Carry has at most 1-2 hours here. Oh.
Recipro Turbo functions by simple math, use a lot of energy for a quick burst. Overuse the Recipro Turbo and your engines will stall.
OVERDRIVE functions differently. Guess what happens when a car goes its max speed, and you don't stop pressing that gas pedal. Yeah, it's gonna die, but it'll be hella fast. That's this logic, and just like in real...Iida's engines are destroyed, no hope of repair, there's nothing left.]
