BANG.
The heavy oak door struck the stone wall, sending a percussion through the floorboards that Iruka felt in the marrow of his shins.
The classroom anarchy—the desks-turned-pedestals and the war-cries echoing off the rafters—abruptly pressurized into a vacuum of silence.
Ibiki Morino stood in the doorway.
His black trench coat seemed to swallow the afternoon sun, radiating a mass that felt geological, like a cliff face moved into a doorway.
He carried the scent of weathered leather and the stagnant tobacco of the council chambers.
His scarred face remained a fixed map of intent as his gaze raked over the children standing on their furniture.
"So," Ibiki rumbled, the sound a low grind of tectonic plates. A few students in the back row lost their footing, sliding off their chairs with a series of clatter-thuds. "You think you've got what it takes to fight?"
He didn't wait for an answer.
He turned on his heel, his coat billowing with the weight of a storm front.
"Outside. Now."
The schoolyard smelled of parched soil and the sweetness of freshly cut grass.
Iruka stood beneath the shade of a gnarled oak, his palms resting against the rough bark to steady a sudden tremor in his fingers.
Beside him, Ibiki occupied the middle of the dust-choked arena.
He appeared massive, surrounded by a dozen Academy students who looked like brittle twigs against a mountain.
"Show me," Ibiki commanded.
The initial assault lacked any mechanical spine.
Kōji lunged, his purple hair a blur of motion, but Ibiki simply pivoted.
Daichi followed with a reckless kick, his bandaged leg whistling through empty air.
Ibiki moved with the economy of a man who viewed every twitch as a resource to be conserved.
He didn't strike back; he merely existed in the spaces the students failed to occupy.
Huf-huf-huf.
Udon leaned over his knees, his breathing a series of ragged hitches. A thick drip of snot swayed as he looked toward Konohamaru. "We're never... gonna win like this," he wheezed, his face flushed a deep crimson from the exertion.
Moegi slapped the dust from her leggings, her orange pigtails drooping. "We need teamwork, kore!" she moaned, her voice cracking.
Konohamaru stepped forward.
He didn't yell.
Instead, he wiped a streak of black earth across his cheek and locked eyes with the others.
The frantic electricity in his gaze had settled into a hard, focused light.
"Nobori! Matsuri! Position B!" Konohamaru barked.
The shift happened in a heartbeat.
The students stopped their individual flailing, moving in a coordinated orbit.
"Multiple String Light Formation!"
Six students dropped to their haunches.
Nobori anchored his black strings into the soil, his fingers digging into the cool earth before channeling.
Matsuri widened her stance to absorb the coming load.
Zzzzzt-vroom.
A grid of luminescent chakra cords erupted from the ground, weaving a barrier that pinned Ibiki's boots.
Iruka watched the kids' faces drain of color.
The sync-lag between their signatures created a discordant hum that made Iruka's teeth ache; the jutsu dragged the color from their faces as it pulled from reserves their young bodies weren't yet used to surrendering.
"Now!" Konohamaru roared. "Shadow Clone Jutsu!"
FFFFFLPPPPPPTTTT.
White smoke occluded the yard, smelling of spent magnesium.
Three versions of the Hokage's grandson materialized.
They converged on the central Konohamaru, their hands meeting in a frantic, circular motion.
A high-frequency whine began to drill into Iruka's ears.
Between their palms, a sphere of swirling energy coalesced—a mini-Rasengan no larger than a tennis ball.
It wasn't a perfect orb; the surface wobbled with an unstable rotational force that blurred the air.
Konohamaru's wrist strained, the tendons standing out like iron wires.
A thin line of blood escaped his nostril as the raw energy taxed his undeveloped pathways.
"RASENGAN!"
Konohamaru lunged.
The blue sphere connected with the interrogator's chest—CR-ACK-BOOM.
POOF.
The Ibiki in the center of the light formation dissolved.
A vacuum of air pulled at the dust before a charred wooden log fell into the ground, splintered and smoking.
The barrier collapsed instantly.
The luminescent strings remained etched in the soil for a second, glowing a dying amber before fading.
Nobori fell backward, shaking his hands as if they'd been scorched; he couldn't quite dispel the residual sparks clinging to his skin.
Matsuri doubled over, clutching her stomach against a wave of nausea.
In the center of the yard, Konohamaru lay prone.
He tried to push himself up, his arms trembling until they gave out, sending him down into the dust.
He quickly wiped the blood from his nose with his sleeve, masking the failure with a stubborn grunt.
His eyes darted around to see if anyone noticed, but everyone–save for Iruka–was preoccupied.
An acrid taste of earth and ash settled in the back of Iruka's throat.
The smell of burnt pine resin drifted from the scorched log.
Ibiki stood by the fence, silently scanning the students' staggered breathing patterns.
One of them coughed into their hand.
Konohamaru was on one knee now, clutching his fist and snot-faced–not crying out of defeat–but with tears of accomplishment.
The determined half-grin on his face was proof enough.
Ibiki's weight shifted, his shoulders squaring as he gave a small, nearly imperceptible nod toward the wreckage of the substitution.
"Not bad." He muttered, just low enough that the kids wouldn't hear.
Iruka couldn't tell if the nod was for the trap or the strike.
"Isn't that mean?" Iruka asked finally, his voice sounding thin against the wind. "To let them think they had you?"
Ibiki scoffed, his gaze never leaving the boy in the dust. "To give them hope, even briefly?"
Iruka's back prickled with heat—the memory of a collapsing roof, the sting of cinders, and the solid, warm weight of the Third Hokage's hand on his shoulder amidst the freezing ash of his childhood.
It hadn't been a lie; it had been the only fire hot enough to keep him from turning to stone in the cold.
"It keeps them from freezing," Ibiki continued, his voice a grounded rumble. "Better they find out how to breathe under pressure here, before the real blood starts flowing."
"We raise them," Iruka murmured, his fingers digging into the rough oak bark.
"For the next generation," Ibiki added.
"To protect the village," Iruka continued, watching Matsuri slowly help Udon to his feet.
"To build it or to burn it," Ibiki finished. He stepped toward Iruka and clapped him on the back. The heavy impact jarred Iruka's spine, anchoring him back into the schoolyard. "Enough philosophy. Let's get some food."
Iruka looked at his class.
They weren't laughing yet.
Some were suppressing dry heaves, while others flexed fingers that still wouldn't fully close.
They were brushing dirt off, their eyes wide with the realization of how far the mountain still reached.
He tucked his class roster into his vest and followed Ibiki toward the gate.
