The heavy brass-grated elevator doors closed with a soft clang, shutting out the sterile, climate-controlled air of the Student Council Building.
Jun Izanami stood in the middle of the cramped carriage, hands tucked casually into his jacket pockets.
Next to him, Ririka Momobami stood straight, her platinum hair glinting under the dim, flickering light above.
Her sky-blue eyes stayed fixed on the digital floor display over the door, tracking the numbers as they dropped past the basement levels and slid deep into the negatives.
The elevator's air pressure changed, trading the crisp, cool oxygen of the upper floors for a thick, muggy heat tinged with the scent of rust, old sweat, and copper.
In the heavy silence, the elevator jolted to a stop, and the doors creaked open.
The heat hit them first—a heavy, stifling wave of body warmth and desperation. Then came the noise: a wild, overwhelming mix of shouts, sobs, the rattle of flimsy plastic chips, and the dull smack of flesh against concrete.
This was the Pit.
At the very bottom of Hyakkaou Private Academy, The Pit was nothing like the grand halls above.
If the upper floors were a mausoleum for the elite, this was a slaughterhouse for the defeated.
The ceiling sagged low, supported by thick, rusted pipes that dripped condensation onto the cracked concrete floor. Harsh light from caged industrial bulbs spilled across the space, throwing long, sickly yellow shadows.
In view, hundreds of students crowded the narrow walkways.
They weren't dressed in the pristine red blazers of the upper levels, but in torn shirts and sweat-stained skirts, with heavy metallic tags around their necks marking them as Housepets—Fido, Mittens, Spot.
They crawled along the floor, serving as living chairs, holding ashtrays, or licking the shoes of high-rollers seated at the makeshift, blood-stained tables.
Ririka's breath caught, her hands balling into fists at her sides.
She recognized this place all too well—the choking fear of the metal collar, the degrading chill of the concrete floor.
Jun shifted his weight without a word, taking just one step forward.
The temperature around him plummeted, the thick, humid air crystallizing into a small pocket of frigid, dense pressure.
The tangible weight of his presence seemed to roll outward, pushing heavily against the concrete walls.
The students closest to the elevator fell silent. The high-rollers froze mid-motion, hands suspended above the tables.
The Housepets on the floor stopped crawling, pressing their faces into the grimy concrete, their bodies trembling on instinct.
A path has been made and cleared.
It began at the elevator doors and spread down the main corridor, slicing through the crowd of desperate gamblers and weary students.
No one said a word or dared to meet Jun's eyes.
Instead, they stared at the floor, hearts pounding, instincts urging them to clear a path for the apex predator moving through their territory.
Jun strolled down the middle of the path, with Ririka trailing just half a step behind, her head high and eyes set straight ahead.
She didn't glance at the housepets or the blood on the tables. Her gaze stayed fixed on Jun's back, finding comfort in the steady, unshakable certainty of his presence.
They reached the end of the corridor and stopped in front of a heavy, reinforced steel door marked with a single, peeling red numeral: VIP-0. Without wasting any time, Jun pushed the door open.
°•°•°•°•°•
The VIP room was a stark contrast to the chaotic grime of The Pit. It was small, soundproof, and icy cold, with dark padded walls that muffled every sound.
In the center sat a lone round iron table, flanked by two sturdy steel chairs. There were no chips, no cards—nothing at all.
Inside, there was already someone—a woman sitting in one of the chairs.
She looked to be in her early twenties, with short, choppy black hair.
Dressed in a plain dark turtleneck and leather gloves, she had a thick black silk blindfold tied snugly over her eyes, completely blocking her sight.
Her name was Yua.
The woman didn't glance up when the door creaked open. She remained perfectly still, her hands lying flat on the cold iron table.
"Welcome… and you're really loud," Yua said, her voice soft and melodic, yet carrying an odd, echoing resonance, like she was speaking from the bottom of a well.
"Your heart rate is up, Momobami Ririka. Sixty-eight beats per minute. You're scared, but trying to hide it." Ririka tensed.
Yua tilted her head a bit, nostrils flaring. "And you… Izanami Jun. Heart rate at fifty-two—resting, calm...
...You smell like high-altitude mist, roasted starlight, Astral Oolong."
A faint, uneasy smile played on Yua's lips. "You made tea in the Student Council room. The scent's still clinging to your jacket fibers. It's lovely—like the smell of peace."
Jun stepped forward and slid the steel chair out from across the table. He sat, the metal legs screeching against the concrete floor. Ririka settled into the seat next to him, resting her hands neatly in her lap.
"You're Y," Jun said, his tone easy and conversational.
"I am," Yua said, slipping a hand into the pocket of her turtleneck to pull out a small velvet pouch. She set it down on the iron table.
"I heard about the enforcer you dealt with upstairs. Gozu was nothing more than a blunt instrument, like a hammer. The syndicate sent him to break you… but as we expected, you don't crack under pressure—you just fade away.
Yua loosened the velvet pouch and drew out two tiny crystal vials, each brimming with a swirling, iridescent silver liquid. She set one before Jun and kept the other for herself.
She then pulled out two sleek black, medical-grade heart rate monitors with biometric cuffs and slid one across the table to Jun.
"The game is called Mnemosyne's Drop," Yua said, her blindfolded face aligning with him unerringly.
"The liquid in those vials is a potent, neuro-reactive extract sourced from deep-sea pufferfish and rare alpine fungi...
...Upon touching your tongue, it bypasses the logical brain to directly stimulate the amygdala and hippocampus, compelling you to relive your most intense, emotionally charged memory...
..The pain, grief, terror, and ecstasy—all magnified a hundredfold."
She tapped the heart rate monitor. "Strap this on your wrist—it tracks your pulse, galvanic skin response, and even tiny tremors"
"The rules are simple: we each take a drop, let the memory hit, and the first one whose heart rate goes over one-twenty, or who lets a single tear fall, loses."
"..." Jun stared at the silver liquid as it swirled lazily inside the crystal vial, glinting faintly in the dim light.
"And the stakes?" Jun asked.
Yua's smile grew, revealing flawless white teeth. "If you lose, the neural overload will fry your emotional centers for good. Your most treasured memory will vanish forever, leaving you an empty, grinning shell. I'm taking your mind."
At those words, Ririka's head whipped toward Yua, her eyes flashing with fury. "That's crazy! That's murder!"
"Oh my... it's a gamble,," Yua purred. "If I lose, you get the complete, unredacted ledger of Oko Shinomiya's syndicate—every account, every alias, every dirty secret he's using to hunt you. And you'll have my network too."
"Remember this... I'm the eyes and ears of the underground. Win, and you own the shadows of this city."
Jun glanced at the vial, then at the heart rate monitor.
"Deal," he said, as if it meant nothing to him.
He grabbed the black cuff and fastened it around his left wrist. A single beep signaled it had synced to his pulse—fifty-two beats per minute.
Ririka slipped a digital stylus from her coat pocket and tapped the screen, approving the Life Plan merger for the stakes. She met Jun's gaze, her eyes blazing. "I'm with you."
"Begin," Yua whispered.
She grabbed the vial, popped the cork, and let a single drop of the silver liquid touch her tongue. The effect was instantaneous the moment it made contact.
Yua's back arched sharply, her hands hitting the iron table with a thud as the leather of her gloves squeaked against the cold metal. Her head tilted back, the black silk blindfold taut against her skin, and a raw, painful gasp escaped her lips.
The monitor on her wrist beeped faster and faster.
Eighty... ninety... a hundred and five...
Sweat burst across her forehead, sliding down her pale cheeks.
Her whole body shook, rattled by the force of whatever nightmare gripped her.
The air grew heavy, thick with the sharp, metallic scent of fear.
One hundred and fifteen...
Yua clenched her teeth so hard the faint grind of enamel filled the tiny room.
She slowed her breathing, digging her nails into her palms, using the sharp sting to steady herself against the crashing surge of mental anguish.
Slowly, painfully, the numbers on her monitor ticked downward.
One hundred ten... one hundred five... one hundred.
She leaned forward, pressing her forehead to the cold iron table, struggling for breath as her chest rose and fell.
"One hundred and two," Yua said hoarsely, her voice trembling as tears of blood seeped from beneath her blindfold, staining the black silk.
"I remember... the night they took my eyes. The pain, the screams. I kept count—one hundred and two."
She lifted her head, angling her blindfolded face toward Jun. "Your turn, Chef. Let's see what you've got hidden in the dark." Jun picked up his vial and popped the cork.
The silver liquid carried a faint scent of ozone and crushed lotus blossoms. He let a single drop fall onto his tongue.
The first thing he felt was the cold—it hit him hard.
A freezing, electric jolt shot up his jaw and burst behind his eyes.
The world around him faded away. The soundproofed walls, the iron table, the humming monitors—all disappeared into a blinding, silent white.
In an instant, his Absolute Learn kicked in, scanning the neurochemical attack and tracing the synaptic routes the liquid aimed to seize.
It pushed to pull him into darkness, to dredge up the memory of the Shinomiya thugs smashing through his door, the crash of shattering glass, the crack of his grandfather's wooden grinder breaking apart.
It pressed to stir the anger, the fierce protective rage, the fear of losing his home.
Jun's mind instantly dismissed the path.
He shifted his focus, sidestepping the amygdala's panic response and channeling the neural energy into a different, well-worn synaptic pathway.
He chose the memory.
The white shifted into a warm, golden glow.
In the memory, he was twenty, just as he is now, standing in the kitchen of Sazanami Cafe.
It was early morning, three years back, and the sun was just starting to rise over Mirror Lake, sending long, gentle beams through the wide glass windows.
The air was rich with the scent of roasted coffee beans and fresh, damp earth.
He recalled gazing out the window to find Ririka, her white mask in place, sitting quietly on the deck as she fed a stray cat. When she looked up, he could sense the gentle, cautious warmth in her eyes, even through the mask.
It was a memory of pure, simple peace, the very core of his being. There was no pain, no fear, no anger—just a deep, steady joy and a quiet, unwavering love.
The neurochemical liquid crashed into the memory, searching for a crack, pushing to jolt his adrenaline, desperate to draw out a tear.
The memory was vivid, a fortress of warmth. The liquid flowed over it and faded away, dissolved by the deep, unshakable calm of the moment.
In the VIP room, the heart rate monitor on Jun's wrist beeped—fifty-two. Yua's head whipped toward the sound—fifty-two.
Jun sat completely still, his posture easy and unhurried. His hands lay lightly on the iron table, while his slow, deep breaths followed a steady rhythm.
His face was calm and peaceful, with just the faintest hint of softness at the corners of his eyes.
Fifty-one.
The monitor emitted a steady, unchanging tone. His heart rate stayed perfectly even, his skin temperature held steady, and his pupils, just visible beneath relaxed eyelids, showed no sign of dilation.
Yua's eyes widened, her breath coming in sharp bursts. "That's… impossible!"
"The extract triggers emotional overload—it should be ripping you apart...
So why isn't your heart rate changing?
What kind of memory… what kind of monster feels nothing?!"
And just like that, Jun's eyes fluttered open.
The golden glow of memory faded from his eyes, leaving them calm and steady once more.
He then turned his gaze to Yua.
The air in the small, soundproof room turned thick in an instant. The temperature dropped sharply, and the condensation on the pipes froze into delicate shards of frost. The oppressive weight of his presence bore down on the iron table, causing the metal to creak.
Yua gasped, clutching her throat as if the air had been sucked from the room. Her monitor blared in alarm. One hundred and ten... one hundred and twenty... one hundred and thirty...
"I feel, Miss Yua," Jun said, his voice a deep, resonant rumble that seemed to rise from the concrete floor itself.
"I feel the sun's warmth, the peace of my home. My memory isn't a nightmare—it's a haven, one that no chemical or anything can shatter."
In no time, Yua's monitor hit one hundred and forty. That made her...
"I lose," she choked out, her voice barely above a whisper.
The monitor let out a flat, unbroken tone. Yua sank into her chair, trembling, utterly spent. Her black silk blindfold was drenched with bloody tears.
Jun slipped the monitor off his wrist and set it gently on the table. The icy tension in the room eased, replaced by a rush of air tinged with the scent of ozone and lotus blossoms.
"The ledger," Jun said with an icy tone.
With trembling fingers, Yua reached into her turtleneck, retrieved a small, encrypted black USB drive, and slid it across the iron table.
"Everything," Yua murmured, her voice empty. "Every account, every operative—Oko's whole shadow empire. It's all yours."
Jun picked up the drive and slipped it into his pocket. He looked at the bloody blindfold covering her eyes.
"You said you were the eyes and ears of the underground," Jun remarked casually, the once intimidating weight in his voice now gone. "But you're blind—so how do you see?"
Yua let out a shaky, broken laugh as she reached up and gripped the edges of the black silk blindfold.
"I'm not blind, Izanami," she murmured, pulling it away. Jun's eyes narrowed, and Ririka gasped softly.
Yua's pale silver eyes were flawless—no scars, no damage—clear and bright.
She could see perfectly. "Then why wear the blindfold?" Ririka asked, confusion in her voice.
Yua stared at the table, the dim caged bulb above catching in her eyes, her face lined with heavy, tired sorrow.
"Because if I can see," she murmured, her voice shaking, "I see the faces of the people I've destroyed. I see the Housepets, the despair everywhere.
Obliviously, I shut my eyes to it.
At the same time, I honed my other senses to avoid confronting the monster I had become just to survive in this city."
She gazed up at Jun, her silver eyes wide and vulnerable, devoid of all her underworld allure.
"You beat me," Yua murmured. "You control my network now. You control my eyes. So, what are your orders, Boss?"
Jun rose to his feet, grabbing his jacket and brushing out the wrinkles.
His fingers brushed the USB drive in his pocket before his gaze shifted to the shattered woman slumped in the steel chair.
"First order," Jun remarked, his voice calm and steady, devoid of sympathy for the syndicate but with a subtle affection for the woman in front of him.
"Put the blindfold back into your pocket. You'll walk out of The Pit with your eyes open. You will look at the Housepets and the gamblers. Then you'll use your network to determine precisely where Oko Shinomiya is sleeping tonight."
Yua fixed her gaze on him, a single clear tear—not tinged with blood—slipping down her cheek. She gave a slow nod.
"As you command, Boss."
Jun turned and headed toward the heavy steel door. Ririka rose, offering Yua a brief, respectful nod, and followed him out, leaving only the quiet click of the door sealing behind them.
Yua sat alone in the cold room, staring at the black silk blindfold in her hands. With slow, deliberate movements, she folded it neatly and tucked it deep into her pocket.
Rising to her feet, her silver eyes caught the light as she made her way toward the door.
Out in the corridor, Jun and Ririka made their way back through the throng of gamblers and Housepets.
The crowd still gave way for them, but the mood had changed. Fear lingered, now blended with a deep, awe-filled respect.
Jun pulled his phone from his pocket and opened the System App, where a cheerful digital mascot greeted him with a wave.
His balance sat at nearly 450,000 Points, so he tapped the screen to order a bulk shipment of Special Grade Hokkaido milk and fresh yeast for the next day's baking prep.
He slipped the phone back into his pocket and looked at Ririka.
"You did good today," Jun said, his voice light, the casual, easygoing chef returning now that the game was over.
Ririka looked at him, a small, genuine smile touching her lips. "I'm your Partner. I'm not going to let you lose."
They reached the elevator, and the doors slid open. As they stepped inside, Jun's phone buzzed again.
He pulled it out to find a message from the encrypted USB drive he'd just slipped into his pocket.
The drive had a short-range Bluetooth transmitter, and it was pinging his phone.
Jun opened the file to reveal a single, high-resolution photograph:
A man in his late sixties, frail and deeply lined, sitting in the back of a Maybach and gazing out through the tinted window.
Dressed in an elegant traditional Japanese kimono, his cold, stern eyes were utterly devoid of warmth.
It was Gan'an Shinomiya—the patriarch, the old man. Beneath the photo, a single line of text had been typed by Yua's network.
The old man's not delegating anymore—he's heading to Mirror Lake himself, and he's bringing the Kyoto branch along.
Jun stared at the screen as the elevator doors slid shut, wrapping them in the rising darkness.
A soft, upbeat jazz tune drifted from the speakers.
Sliding his phone back into his pocket, his dark eyes the glow of the floor numbers ticking upward toward the surface.
The underground was secure and the real war was just beginning.
