Below, the training fields stretched wide and open under a sky that didn’t care what happened beneath it.
Six pairs moved in practiced violence, their footwork pressing divots into damp earth.
Soren’s thumb traced the edge of his scar absently as his awareness pulsed outward—iron signatures flaring like sudden stars against the dark fabric of the world.
The gallery’s own structural beams hummed at the periphery, ignorable as breath.
Two rows ahead, a girl with coiled green hair leaned forward, tracking a lightning-fast exchange between a staff user and someone employing liquid shadow.
To Soren’s left, a broad-shouldered boy muttered calculations under his breath, eyes locked on a duel involving floating blades.
Neither glanced his way.
Then—*her*.
Erza Scarlet stood mid-field adjusting her vambrace, Heart Kreuz plate flaring bright in Soren’s senses like a struck bell.
The sparring partner opposite her rolled his shoulders, flames licking between his knuckles.
Soren exhaled through his nose and catalogued the minutiae: the slight variance in her left greave’s alloy, the way her practice sword’s tang vibrated with every micro-shift of her grip.
A whistle cut the air.
Erza moved.
And for the first time, Soren’s Quirk *blinked*—her armor’s iron signature vanished between one heartbeat and the next, replaced instantly by something leaner, darker, threaded with unfamiliar trace elements.
His spine straightened without permission.
She struck low.
Her partner barely parried.
Soren sat very still.
He sat in the back row of the gallery.
With his fingers curled against his knees, he watched the way the iron geometries of the field pulsed beneath each footfall.
Below him the training fields were arranged in three rings—the central circle’s plates thickest where the impacts landed hardest, the secondary ring’s borders threaded with conductive alloys for redirected energy, the tertiary ring’s racks holding weapons that bled traces of oil and old sweat into their tangs.
The green-haired girl gasped as her chosen senior executed a spinning counterattack; the broad-shouldered boy nodded sharply when his subject landed a textbook-perfect disarming strike.
Neither reaction was for him.
Soren counted requips instead—three in twenty minutes, each armor set flaring into existence with its own metallurgical fingerprint before dissolving into whatever pocket dimension Erza pulled them from.
He memorized the way her partner’s fire hissed against sudden plate changes, how her footwork adapted mid-stride when heavier greaves swapped out for flexible chainmail.
By the time the hour ended, his scar throbbed from how tightly he’d pressed his thumb against it.
The gallery emptied around him, the other juniors already hurrying down to meet their seniors.
Soren remained seated, eyes tracking the last sparks of iron signatures dispersing across the field.
He had no senior to watch in particular.
The seniors below began sorting themselves into pairs.
There were no instructors—Saturday sparring was self-regulated, senior-ranked students trusted to train without oversight.
Soren cataloged them as they moved: the chain-user with her weighted links already spinning lazy circles, the sword-mage flipping throwing knives between his fingers, the broad-shouldered senior clanking in pre-merger ironplate that smelled of coal and old blood.
None of them were Erza.
The murmur of conversation died mid-syllable.
Three juniors in the gallery leaned forward as one.
Then Erza came through the FT-side door in Heart Kreuz armor.
Erza paired with a senior who used fire and fenced.
The tall man inclined his head slightly—not deference, but acknowledgment of tier—before settling into an en garde position, flames curling down the length of his practice rapier.
Soren’s fingers twitched against his knees as he registered the duel’s opening iron signatures: Heart Kreuz’s dense chromium-molybdenum alloy, the faint nickel sheen of the fire-fencer’s gorget, the carbon-steel core of Erza’s wooden sword wrapped in illusionary flame.
Their first exchange lasted seven seconds.
Erza’s blade flickered out in a testing thrust; her partner pivoted on his lead foot, redirecting the strike with a fire-wreathed parry that sent embers skittering across the central ring’s iron plates.
Soren tracked the way her armor’s weight distribution shifted—left vambrace dipping three millimeters lower than the right as she recovered, the alloy singing in his awareness with every micro-adjustment.
Then, between blinks:
Nothing.
The void lasted 0.42 seconds before blackened adamantine plate materialized in its place, lighter by seventeen pounds.
Erza’s next strike came faster, her body a sudden dark blur that forced the fire-fencer into a backstep.
The gallery’s wooden railing creaked as the green-haired girl gripped it tighter.
Soren didn’t blink.
She won the first exchange and he won the second.
During the third exchange she requipped into a black lighter set.
Soren’s breath caught—not at the speed (though it was brutal, her footwork suddenly liquid where plate had been solid), but at the *absence*.
The vanishing.
The way Heart Kreuz’s iron signature dissolved between one instant and the next without traversing space, replaced by a new alloy matrix already in motion, already striking.
Like flipping a card to reveal its opposite face.
The fire-fencer barely got his rapier up in time.
Flames licked across the black adamantine vambrace, heat-warping the air—but Soren’s focus stayed locked on the metallurgical ghosting.
One heartbeat: chromium-molybdenum latticework humming at 87% density.
The next: hollow.
Then—adamantine, thinner, threaded with vanadium traces that sang higher in his awareness.
No transit.
No path.
Just—
*Change*. Enjoying the story? Read on at g.com.
Erza’s knee came up, armored greave slamming into her partner’s ribs hard enough to send him skidding back across the central ring.
The gallery’s wood creaked under shifting weight as the green-haired girl whispered something urgent to her neighbor.
Soren didn’t hear it.
His thumb pressed harder into his scar, iron-echoes reverberating behind his eyes like afterimages from a flashbulb.
The fire-fencer rolled to his feet, flames wreathing his practice blade brighter—but Erza was already pivoting, already shifting her center of gravity for the next exchange.
Soren watched the way her new armor’s iron distributed itself: lighter across the shoulders, denser at the joints, every plate calibrated for acceleration over endurance.
Below, the chain-user’s weighted links whipped through the air in complex patterns; to the left, the sword-mage’s throwing knives embedded themselves in straw targets with dull thuds.
Normal combat.
Normal iron movement.
Erza’s next requip came twelve seconds later—back to Heart Kreuz mid-parry, the sudden weight differential making her opponent overbalance as his flames licked uselessly against renewed plate.
Soren’s teeth clicked together at the transition’s sensory discontinuity: *gone-here* with no in-between.
By the time the dismissal bell rang, his palms ached from how tightly he’d curled them against his knees.
The gallery emptied around him, chatter rising as juniors descended to congratulate their chosen seniors.
Soren remained.
Below, Erza unclasped her vambrace without looking up.
He had no name for what he’d registered.
She requipped twice more across the next twenty minutes.
First, back to Heart Kreuz—the familiar chromium-molybdenum alloy slotting into place mid-sidestep, her partner’s fire glancing off the renewed plate with a hiss.
Then, three exchanges later, into something entirely new: silver-blue scaled mail that rang like struck crystal in Soren’s awareness, its metallurgy unlike anything else on the field.
Each transition carved itself into his senses—absence, presence, no bridge between.
He filed them away as anomalies his Quirk didn’t yet comprehend, patterns waiting to be deciphered.
The gallery’s remaining stragglers shuffled out, their footsteps dull against worn wood.
Soren waited until Erza’s final bout concluded, until she’d sheathed her practice blade without glancing toward the observation deck.
When he stood, his knees protested from stillness.
Below, the fire-fencer was laughing now, clapping Erza on the shoulder as if the bruise forming along his ribs meant nothing.
She inclined her head, but her gaze never strayed upward.
Soren tucked his notebook into his pocket—pages dense with alloy ratios and transition timings—and turned toward the exit.
The corridor encounter hadn’t been the start of anything.
Just a flicker.
A misread.
She gave no sign of knowing he was up in the gallery.
