The classroom buzzed with anticipation.
Students leaned forward in their seats, whispering guesses and groaning predictions as Captain Jūshirō Ukitake stood at the front, clipboard in hand. The morning sun angled in through the broad windows of Shin'o Academy, casting long, golden streaks across the polished wood floor.
"Today marks your first practical field exercise," Ukitake said with a soft smile, his white uniform billowing gently with the breeze. His voice carried warmth, but also gravity. "You will be deployed in pairs to outer Rukon Districts, where you'll assist with local stability, quell minor disturbances, and if necessary… eliminate low-threat Hollows."
He glanced over his glasses, eyes calm but sharp.
"These assignments aren't simply about combat. You're being evaluated on judgment, adaptability, and how you conduct yourselves as protectors of Soul Society."
A scroll unfurled in his hand with a rustle. Names began to roll off his tongue.
"Yoruichi Shihōin and Byakuya Kuchiki — District 65."
Yoruichi immediately leaned back in her chair, groaning with theatrical flair. "Again with the stick-in-the-mud," she muttered.
Byakuya, seated perfectly upright, gave no reaction beyond the slight narrowing of his gaze.
"Urahara Kisuke and Tessai Tsukabishi — District 63."
"Yatta," Urahara whispered, popping a fan open. "Kidō science and muscle, a flawless combo."
Tessai merely adjusted his spectacles with a quiet hum.
"And finally," Ukitake paused, "Aizen Sōsuke and Lan Akira — District 70."
Akira smirked, already rising. "Figures."
Aizen stood with a nod, his face the picture of composed elegance. "Understood, Captain."
From the side, Isshin gave a mock thumbs-up. "Don't get lost, boys. District 70's got a lovely population of grumpy ghosts."
Ukitake smiled faintly. "Stay sharp. Report by dusk. Dismissed."
District 70 – Western Outskirts
The Rukon Districts stretched far and wild beyond the Seireitei's pristine walls. In District 70, the streets were dusty and worn, lined with crooked wooden houses and half-collapsed shops. Children played with sticks in narrow alleys, while elders squinted from shaded doorways, eyes wary of strangers in black robes.
Akira strolled down the main road, hands folded behind his head. His golden eyes lazily scanned the surroundings.
[Area Threat Level: Low][No active Hollow signatures detected][Local unrest: Moderate – crowd disturbances within acceptable range][Auto-Modulation: Spiritual Pressure - Passive Dissuasion Mode]
He barely had to flex his aura. A faint ripple of spiritual pressure rolled off him like warm mist. A group of rowdy souls down the street — shouting, pushing near a bread vendor — suddenly froze. One by one, they stepped back, their instincts screaming before their minds caught up.
"…Tch. Damn Reapers," someone muttered under their breath, but no one resisted.
Akira sighed. "Effortless peacekeeping. System, you're spoiling me."
Behind him, Aizen said nothing.
He was observing — not just the streets, but the air itself.
His hand hovered near the hilt of Kyōka Suigetsu, though he had no intention of drawing it. His senses stretched outward, past the laughter and footsteps, past the ordinary. He felt the flow of reiryoku in the district — the gentle tide that should have moved like a stream.
But here… something eddied.
"Do you feel that?" he murmured, voice soft.
Akira glanced over. "The spiritual current?"
Aizen nodded slowly. "It's fractured. Like something upstream is siphoning off flow… or diverting it."
Akira tilted his head. He reached out with his senses — more out of politeness than necessity. He didn't need to. His system would alert him to actual danger.
Still, now that Aizen mentioned it…
[Analyzing Environmental Spiritual Flow...][...Anomaly detected. Source concentration: 730 meters north-northeast][Classification: Unknown — Not Hollow. Not Plussed. Not Soul Reaper.]
Akira straightened. "You're right."
Aizen's eyes sharpened. "Let's go."
The Shrine
The path north led them through twisting alleys and overgrown fields. Eventually, they found it — an old, crumbling shrine nestled between a pair of ancient stone walls. It should have been abandoned, but the air was heavy with reiryoku — thick, unnatural.
Spiritual particles in the air didn't move. They hung like mist caught in glass.
Aizen stepped inside first.
Every instinct screamed that this place was wrong.
Not Hollow-wrong. Not cursed. But… sterile.
A spiritual void.
He crouched by a cracked offering bowl and ran his fingers across the dust. "There's no decay here," he murmured. "Even abandoned places collect spiritual residue. But here, it's like everything was… leeched."
Akira entered behind him, squinting.
Then he saw it.
At the far wall of the shrine, tucked behind an altar and hidden beneath torn prayer scrolls, was a small seal etched into the stone — glowing faintly. A perfect circle of kanji spiraled around a core symbol neither of them recognized.
[Unknown Sigil Detected. Origin: Unknown. Composition: Soul King Fragment Resonance][Warning: Spiritual Drain in effect. Exposure time exceeding safe limit.]
Akira immediately stepped back. "That symbol," he said, voice colder now, "It's drawing ambient reiryoku into itself. Feeding on it."
Aizen examined it carefully. His glasses caught the faint light, reflecting it like a mirror. "It's not a Hollow construct. Nor Kidō. This is ancient."
He looked to his brother. "Do you think the Gotei knows about this?"
Akira shook his head. "If they did, it wouldn't be buried under a broken shrine in District 70."
He knelt down, studying the edges of the seal.
Aizen followed, eyes narrowing.
"Look at this," he said softly. His fingers hovered over a mark — one that had been scratched into the side of the altar. A stylized crane intertwined with ivy.
Akira's smile vanished.
"That's the crest of the Tsunayashiro Clan."
One of the Four Great Houses.
Both of them stood in silence.
"This isn't a mistake," Aizen said at last. "They planted it here. Hidden, draining ambient reiryoku from the Rukon. Why?"
Akira crossed his arms. "Soul King fragments, maybe. Stabilization testing. Or something worse."
Outside, the wind rustled the trees. A whisper carried on it — faint, mournful, almost human.
Aizen stepped back and turned toward the door, his smile thin. "We report this."
Akira hesitated. "To who? Central 46? The Gotei? You know what they'll do."
"Bury it," Aizen finished.
The brothers exchanged a look — one of unspoken understanding.
"We collect the data ourselves," Akira said. "Then we see how far this web reaches."
Elsewhere — A Parallel Thread
In District 65, Yoruichi and Byakuya fought side-by-side — a pack of minor Hollows overwhelmed them, but it was still a physical struggle. Yoruichi struck like lightning, while Byakuya's precision crushed them one by one.
In District 63, Urahara and Tessai stood before a collapsed shrine of their own, analyzing leyline disruptions caused by minor spiritual imbalances. Tessai frowned, noting the distortions. Urahara hummed thoughtfully, tapping his fan.
"Something about this smells wrong," Urahara muttered. "Too neat. Too deliberate."
Back in Seireitei – Ukitake's Office
Ukitake reviewed the scrolls of field reports.
Districts 63 and 65: Hollow activity, manageable. Minor unrest resolved.
District 70: No incidents reported. All clear.
Ukitake frowned.
"Too quiet."
Cliffhanger: Beneath the Shrine
As the brothers turned to leave, a crack formed beneath the seal.
Something watched them from the gap in space.
Not a Hollow. Not a spirit.
Something... other.
[Entity Logged: ???][Classification: Suppressed — Soul King Residual Signature Detected][System Warning: Observation Logged by External Force]
Akira's steps slowed.
"Did you feel that?"
Aizen's eyes glinted. "Yes."
Something had taken notice.
And it wasn't done watching.
