The orders came down through the Central 46 liaison office: a mandatory joint boundary sweep of the 79th District, Kusajishi.
On paper, it looked like standard administrative busywork.
The Tenth Division provided territorial security; the Fifth Division provided tactical research support.
In reality, it was Aizen setting a board where nobody could hear the pieces move.
The midday sun beat down on the desolate, red-dirt wasteland of District 79.
Jagged rock ridges jutted into a cloudless sky, surrounded by crumbling shanties and abandoned iron mines.
Kazuma walked along the dry canyon floor, his straw hat tilted low, hands tucked deep into the sleeves of his white Captain’s haori.
Beside him, strolling with light, effortless poise, was Fifth Seat Sōsuke Aizen.
Behind them walked six unseated Fifth Division researchers carrying bronze resonance censers, their faces pale under the dry heat.
“You know, Aizen-kun,” Kazuma said, his voice flat with mild irritation, “District 79 has nothing but scorpions, bad water, and bandits who don’t know how to bathe.
If your division wanted to collect soil samples, you could have dug up the flowerbeds outside the Fifth Division barracks.”
“The spiritual particulate density in Kusajishi is unique, Captain Kazuma,” Aizen replied pleasantly, his hands folded behind his back.
“The soil here has absorbed centuries of unpurified Hollow residue.
A fascinating medium for studying rapid soul degradation.”
“Fascinating,” Kazuma muttered.
“I’m already bored to tears.”
They turned a bend in the canyon wall.
The narrow gorge opened into a massive, sunken stone basin—an abandoned open-pit quarry surrounded by towering, sheer rock faces.
The air inside the basin was unnaturally thick, smelling faintly of sulfur, old blood, and ozone.
In the center of the quarry stood a wooden containment pillar bound in heavy Kidō chains.
Wrapped around the pillar was a live Adjuchas.
It was a serpentine monstrosity twenty feet long, covered in thick, dark-green bone scales, its elongated skull mask split into four distinct jaw sections.
Unlike wild Hollows that howled and thrashed against their bonds, this specimen was dead silent.
Its yellow eyes were cloudy, drugged with high-grade spiritual sedatives, while a faint crimson resonance rune pulsed on the center of its forehead.
Kazuma stopped three paces from the lip of the pit.
Under the brim of his straw hat, his eyes narrowed by a fraction of a millimeter.
‘Artificial soul grafting,’ Kazuma analyzed instantly.
‘The rune on its head is a remote resonance trigger.
The moment the chains break, it will vent an engineered spiritual surge.
He didn’t bring me here to fight a Hollow—he brought me here to test the upper limit of my kinetic absorption under compressed blast conditions.’
“An impressive specimen, is it not?” Aizen said softly, stepping up beside Kazuma.
“My research team captured it near the southern border two nights ago.
We brought it here to test its reaction to high-density Kidō barriers.”
“Looks like an oversized lizard with bad skin,” Kazuma said, yawning into his palm.
“Kill it with a Hadō #33 and let’s head back.
The noodle vendor near the North Gate closes at four.”
“However—”
Aizen raised his right index finger.
Behind them, high on the quarry rim, two hidden Kidō nodes flare with pale white light.
*SNAP.*
The heavy iron chains binding the beast didn’t just unlock; they shattered under a sudden, violent spiritual surge.
The red rune on the creature’s skull flared blindingly bright, burning away the sedative fog in its brain in a microsecond.
The Adjuchas’s four jaws split wide open.
A deafening, high-frequency screech tore through the canyon, shattering the loose shale along the cliffs.
The beast’s spiritual pressure didn’t rise gradually—it exploded into a dense, purple miasma that instantly crushed the six unseated researchers to their knees, knocking them unconscious where they stood.
The beast locked its four jaws onto Kazuma, coiled its massive serpentine body, and launched itself out of the pit at terrifying speed.
As it flew, the crimson rune on its skull ignited with pure, super-condensed Reishi.
It wasn’t charging a standard Cero.
The creature’s entire physical body was collapsing inward, turning itself into a living spiritual bomb designed to detonate in a zero-distance shockwave.
A blast large enough to level the entire quarry and strip away every drop of concealed spiritual pressure in the area.
Aizen stepped back half a pace, his spectacles reflecting the violent purple light, his eyes wide and razor-sharp, watching Kazuma’s hands, his blade, his feet, his breath.
‘Show me,’ Aizen’s thoughts were cold and triumphant.
‘Release your Shikai.
Reveal your true boundary.’
Kazuma didn’t draw his sword.
He didn’t take a combat stance.
He simply took one slow step forward, pulled his right hand out of his wide sleeve, and extended his open palm toward the incoming detonation.
*Jakumetsu: Absolute Null.*
The world didn’t explode.
The massive, charging serpent hit an invisible, flat wall of absolute zero three inches from Kazuma’s outstretched palm.
The instant its scales touched that boundary, every single vector of forward momentum ceased to exist.
The air didn’t compress; the sound of the screech died mid-throat.
The super-dense Reishi bomb collapsing inside the beast’s skull was stripped of all kinetic vibration, thermal excitation, and spiritual frequency in less than a thousandth of a second.
The blinding purple light simply…
turned off.
The creature’s twenty-foot body hung frozen in mid-air for one impossible second, entirely weightless, entirely motionless, its eyes turning milky white as every molecule within its physical form dropped to zero kinetic energy.
Kazuma curled his fingers into a loose fist, then flicked his index finger lightly against the monster’s frozen snout.
*TINK.*
The sound was like a fingernail tapping a crystal wine glass.
The entire twenty-foot Adjuchas—scales, bone armor, flesh, and spiritual core—collapsed into a fine, gray dust that fell straight down into the dirt like a bag of dry flour.
No shockwave.
No heat.
Just a neat, three-foot pile of gray powder sitting at Kazuma’s sandals.
The canyon went dead silent.
The wind blew through the rocks, carrying away the faint scent of sulfur.
Kazuma lowered his hand, shook out his loose sleeve, and looked down at the pile of dust with an expression of mild, profound disappointment.
He turned his head toward Aizen.
Aizen was standing completely frozen.
His hand, which had been resting casually on the hilt of Kyōka Suigetsu, was locked tight.
His pupils were pinned, staring at the empty air where a high-grade living bomb had just vanished without making a sound.
Kazuma scratched the back of his neck, letting out a heavy, exhausted sigh.
“I told you, Aizen-kun,” Kazuma said, his voice sleepy and completely unimpressed.
“Kusajishi lizards have terrible bone density.
One sudden stop and they turn right into dust.
You really need to pick better specimens for your homework.”
Aizen’s jaw tightened by a fraction of a millimeter before he slowly forced his shoulders to relax.
He looked up from the dust to Kazuma’s dull, gray eyes.
“An…
extraordinary display of structural frailty,” Aizen said, his voice silky smooth, though a faint, cold edge sliced through the tone.
“To reduce an Adjuchas to dust with a single finger…
you truly are a remarkable Captain, Kazuma-san.”
“Not remarkable.
Just lazy,” Kazuma said, turning his back and walking toward the canyon exit.
“Carry your sleeping squad members back to the barracks.
If I miss the noodle shop because of your lizard, I’m making you pay the bill.”
Aizen stood alone in the basin for a long moment, watching Kazuma’s white haori sway casually in the desert wind.
Aizen reached down, pinched a bit of the gray dust between his fingers, and rubbed it.
There was no residual heat.
No trace of spiritual frequency.
The molecular bonds hadn’t been cut or burned—they had simply stopped existing.
Behind his glasses, a slow, predatory grin spread across Aizen’s face.
‘Absolute cessation of motion,’ Aizen thought, his heart racing with pure, dark exhilaration.
‘Not a defender of the status quo.
A predator who sleeps on the throne.’
The fifth seat stood up, brushed the dust from his fingers, and bowed slightly to the empty canyon.
“Until next time, Captain Kazuma.”
