The brass bell above the front door had long since gone still, but the silence it left behind hung heavy as lead, draping itself over the hardwood floor like a stifling blanket.
Yumeko Jabami lounged on a tall walnut stool, her sleek hime-cut black hair cascading over her shoulders like smooth, polished obsidian.
Her deep burgundy eyes shimmered with a wild, unnerving crimson flicker, as if devouring the gentle golden glow of the pendant lights overhead.
Between her and Jun sat a brand-new, factory-sealed deck of cards, its sharp white edges catching the light.
At the back of the room, Ririka Momobami stood frozen beside the commercial espresso machine.
She clutched the stainless-steel edge so hard her knuckles turned pale, her breaths short and quiet.
At the secluded corner booth, Kaguya Shinomiya had set her leather-bound report face down.
Her dark crimson eyes stayed fixed on Yumeko with deadly focus, while next to her, Hayasaka kept her right hand hidden inside her blazer, fingers clenched firmly around the grip of her concealed taser.
Across the counter, Erina Nakiri stood with her arms crossed, her famed 'God Tongue' practically buzzing with irritation at the blatant, disrespectful nerve of the intruder.
"Blind Man's Bluff," Jun said, drawing out the words.
His voice was a calm, low baritone, completely unfazed by the stifling psychological tension in the room.
He casually leaned against the stainless-steel prep counter, arms folded over his apron.
"I haven't played that since my university days," Jun remarked, a faint, dashing smirk curling at the corner of his lips. "Remind me of the house rules, Jabami-san."
Yumeko pressed her long, slender fingers to her warm, blushing cheeks.
She let out a soft, breathy giggle—so wild and laced with chaotic joy that every hair on Ryota Suzui's arms stood on end.
"Oh, Izanami-san! The rules are so beautifully and wonderfully simple," Yumeko purred, her voice a melodic chime tinged with a hint of danger.
She reached into her structured leather schoolbag and pulled out two long, wide strips of thick black silk.
The material was heavy, completely opaque, and smooth without a single seam.
"We both wear these," Yumeko said, pushing the silk across the dark walnut surface until it came to rest just an inch from Jun's hand.
"Total sensory deprivation. Hisako-san will serve as our impartial dealer. She shuffles, cuts, and hands each of us a single card. The higher card wins the pot. But..."
She leaned in, her red eyes shining in the fading light.
"...we can each swap our card once before the reveal, and bet as many chips as we like. Fold, and you lose your wager. Call my bluff, and if I've got the higher card... this café is gone. For good."
Ryota gulped, the dry click of his throat loud in the tense air as he edged forward, fear etched on his face. "J-Jabami-san! You can't just bet a man's livelihood on a card draw! What's at stake for you?!"
Yumeko tilted her head just a bit, her smile curling into a perfectly eerie crescent.
"If I lose," Yumeko said quietly, "I'll walk away from Hyakkaou Private Academy, cut all ties with the Momobami clan, and swear off every card, die, and chip for the rest of my life."
"My whole future as a gambler... on the line against this quiet countryside haven."
Erina smacked her hand against the walnut counter, the sharp crack ringing through the hall as her magenta eyes burned with anger.
"This is pure madness! You walk into a respectable place and threaten a local business owner with some wild bet! I'm going to call the—"
"Erina," Jun cut in.
His voice didn't get louder, but it sank a whole octave, laced with a calm, weighty authority that stopped the God Tongue in her tracks.
Jun uncrossed his arms, his long fingers extending to grasp the two black silk blindfolds.
The fabric was cool and heavy, exuding an impenetrable darkness against his skin.
He did not glance toward Kaguya, whose poised fingers hovered over her phone, ready to initiate a tactical strike.
Nor did he turn to Ririka, who trembled so violently that the linen napkins in her grasp quivered like brittle, wind-tossed leaves.
Jun kept his eyes locked on Yumeko's.
"Hisako," Jun said with ease, glancing slightly toward the pink-haired secretary by the register.
"You're dealing. Shuffle the deck three times, give it a clean two-handed cut, and place the stack right in the center of the felt mat..."
"...If even one card has a nick, bend, or mark, I'll void the hand and toss every last one of you into the lake."
Hisako blinked, her usual calm, professional demeanor faltering for just a moment before she dipped her head in a crisp, formal bow.
"Got it, Izanami-san," Hisako replied briskly. "I'll make sure to stay completely neutral."
The world disappeared into complete, pitch-black darkness.
Almost instantly, his other senses stretched to fill the emptiness, heightened by the lingering rush of the Siren's Peppercorn Oil still pulsing through his system.
The acoustic dampening he'd set up earlier paid off big time—the room was a perfect soundless void, with no echo, no flutter, not even the faintest hint of ambient noise.
He could hear it all—the ragged, shallow, almost giddy breathing of Yumeko Jabami across the table, the crisp, steady thwip-thwip-thwip of Hisako's flawless shuffle, and the frantic, rabbit-quick pulse pounding in Ryota Suzui's jugular just five feet away.
"Blindfolds are on," Jun said into the darkness, his deep voice sharp yet muffled by the ceiling panels. "Deal."
The sound of two cards sliding across the felt was as loud as thunder in Jun's ears. One card drifted to his left, the other to Yumeko's right.
Jun reached out with his right hand, letting his fingertips rest lightly on the smooth paper back of his card.
The instant his skin brushed the paper, Absolute Learn kicked in. Tiny tactile details poured into his mind—every minuscule shift in ink density, the faint grain of the cardstock, and even the barely-there balance of the print's weight.
Seven of Spades.
An average card, neither good nor bad.
"I draw," Yumeko murmured, her voice quivering with a manic edge of excitement. "I'll swap my card."
Jun caught the sharp slide of her original card returning to the deck, followed by the soft, steady glide of a new card slipping across the felt into her waiting hand.
Jun stayed perfectly still. He didn't change his stance or even tweak his breathing by the tiniest fraction.
He'd locked his body into a calm void, his pulse steady at an unshakable 60 beats per minute.
To anyone looking, he was like a stone statue draped in dark apron canvas.
"I'm standing," Jun said quietly.
"Your bet, Izanami-san?" Yumeko giggled, the sound making Ryota flinch.
"Five thousand," Jun answered with ease, sliding a tidy stack of clay chips forward. The crisp clack of ceramic against wood was sharp and final.
Yumeko didn't miss a beat. "Ten thousand. And… I raise."
The game surged into a fast-paced, psychological showdown.
Clay chips clinked, slid, and stacked on the felt in a steady rhythm.
Jun played with icy, calculated precision, letting his Gray personality take full control.
He wasn't just playing the cards—he was playing the room itself.
He caught the tiniest pause in Yumeko's fingers as they hovered, felt the faint drag of her skin on the paper, and tracked the subtle warmth radiating from her hands.
He easily won the first hand, then the second, and then the third.
With each pot Jun pulled closer to his side of the table, Yumeko's breaths grew harsher, her cheeks deepening to a feverish red. She wasn't annoyed—she was getting swept up in the moment.
"Incredible... just incredible, Izanami-san," Yumeko murmured, her voice slipping into a low, husky whisper that carried an intense intimacy, slicing through the stillness of the room.
"You're not sweating, not shifting your weight even slightly, and your heart rate hasn't changed a single beat since Hisako broke the seal on the deck. It's like facing off against a ghost… or a god."
"What kind of nonsense are you spouting, Jabami-san? I'm simply observing the math," Jun said smoothly, his blindfolded face turned toward her.
"You're playing purely on emotion, Jabami-san. You're chasing the thrill of the fall, not the odds of the landing."
"Oh, but probability is just so unbearably dull!" Yumeko exclaimed suddenly.
Then...
BANG!
She smacked both palms down on the dark walnut counter, the sharp crack echoing through the quiet room like a gunshot and making Ririka stumble back with a startled gasp.
Yumeko leaned over the counter, closing the gap until her face hovered just two inches from Jun's blindfolded mask.
Jun caught the unmistakable, heady scent of her aura—dark cherries crushed underfoot, the tang of warm copper, and a crackle like static in the air.
"Let's toss out the rules," Yumeko murmured, her tone losing its sugary playfulness and turning icy, edged like a blade. "Next hand—one card. No blindfolds, no swaps. We won't even look at our cards. The bet's all on who's holding the higher one, judged only by what we say to each other."
Under the black silk, Jun's lips curled into a subtle yet dangerous smirk.
There it is, what a crazy girl, Jun thought, his mind catching up to her sudden shift in real time. This girl... complete plunge into chaos.
She wants to strip away the mechanics until it's nothing but pure psychological warfare.
...Heh... What an lousy girl.
"Fair enough," Jun said, his voice dropping to a low, steady rumble. "But if we're going all-in on mind games, the stakes have to match the gamble. This place.. against your Life Plan. Lose, and you owe me a favor—no strings, no excuses."
"Deal!" Yumeko exclaimed, her manic voice breaking as her fingernails scraped into the hardwood counter.
Hisako's hands shook a little as she picked up the deck. The air in the room felt so heavy it was like a weight on everyone's chest. She gave it one shuffle, two cuts, and laid the last two cards the mat.
Jun kept his card untouched, sitting utterly still, every sense cr to its highest pitch.
The Siren's Peppercorn Oil coursed through him like chilled liquid silver, driving his synapses into a frenzy of accelerated thought.
He could hear dust motes settling onto the acoustic ceiling panels, the minute unraveling of wool threads in Ryota's uniform blazer whispering against the silence.
"I've got a face card," Yumeko said with a smooth, confident tone, her voice radiating certainty.
Jun stayed perfectly still, tilting his head just a bit. "Is that so?"
"I do," Yumeko murmured, her voice a smooth, mesmerizing caress. "I can sense the weight of the ink on the card. It's a King. The King of Diamonds. And I know you know it, Izanami-san."
"So... what's your move? Will you fold your humble hand and keep serving coffee another day? Or will you call my bluff and risk losing your sanctuary for good?"
Driven by adrenaline and dopamine, Yumeko Jabami can't help but let words spill out, straight from her chaotic emotions.
The café was eerily still.
Kaguya's fingers dug into the oak frame of her booth as she silently mapped out escape routes.
Erina fixed her gaze on Jun's blindfolded face, holding her breath.
Ririka clutched her mouth with both hands, tears of anxious tension shimmering in her eyes.
Jun remained motionless.
His Absolute Learn skill processed every detail in the room.
Yumeko claimed she had a King, but the quick, uneven double-beat of her carotid pulse told another story.
Her left index finger gave a tiny twitch against the counter—a subtle, instinctive sign of a lie.
No face card. Just a low one. She was bluffing.
However...
Jun's mind dug deeper into the layers of psychological nuance.
Yumeko was a master of deception, fully aware he was tuned into her pulse and reading her micro-expressions.
She had deliberately slipped in that double-beat, baiting his analysis—a flawless double-bluff meant to make him challenge her, only for her to unveil the winning card she'd been hiding the whole time.
It was a three-dimensional psychological trap, crafted to break a genius who depended on pure logic.
Jun's easygoing smirk faded instantly.
The air inside Café Sazanami didn't just cool—it plunged into a bone-chilling, absolute zero.
The darker side of Jun's aura flared, not in a wild display of menace, but in a chilling, suffocating stillness of razor-sharp clarity.
The air grew so heavy that Ryota stumbled back a couple of steps, gripping his throat as if all the oxygen had suddenly vanished.
Hayasaka tightened her grip on the taser, lowering herself into a ready stance. Jun leaned closer, closing the distance until his blindfolded face was just an inch from Yumeko's.
"You've really pulled off quite the double-bluff, Jabami-san," Jun remarked.
His voice wasn't loud, just a flat, vibrating monotone that seemed to rise from the floorboards, draining every bit of warmth from the room.
"You intentionally raised your carotid pulse and pretended to have a slight twitch in your left hand...
...You wanted me to spot those tells, believe you were bluffing about the King, and call your hand—so I'd walk right into the high card you'd been hiding behind the performance...
...Against any gambler at Hyakkaou, it would have been the perfect move."
Yumeko's breath caught sharply, her burgundy eyes widening beneath the black silk blindfold.
"But you made one fatal mistake," Jun said, his voice lowering to an icy whisper that sent a shiver across her skin.
"You forgot whose roof you're standing under."
Jun reached out his right hand, but he didn't move toward his own card or reach for the mountain of clay chips stacked between them.
He stretched out a long finger and tapped the precise center of Yumeko's facedown card.
"You're holding the Three of Hearts," Jun said, his voice calm but firm. "And I've got the Seven of Spades...
...I call."
The silence that followed was almost deafening...
Ryota forgot to breathe entirely.
Kaguya's eyes went wide, her usual regal composure breaking under the sheer, effortless dominance radiating from the blindfolded chef.
Yumeko sat frozen, hands suspended above the dark wood, her chest rising and falling in quick, uneven bursts.
The wild, electric energy that had been pouring off her moments ago sputtered out, short-circuited by the crushing weight of his words.
With trembling, pale hands, she slowly reached up and slipped the black silk blindfold from her face.
Her burgundy eyes were wide with shock, pupils so dilated they nearly consumed her irises.
She watched Jun as he casually reached up with one hand, slipped off his silk blindfold, and let the black fabric fall onto the counter.
His deep, steady gaze met hers with a calm, unwavering intensity.
Hisako, her face ashen and damp with cold sweat, reached out with shaky fingers and turned both cards face up on the felt mat.
Yumeko drew the Three of Hearts, while Jun revealed the Seven of Spades.
He had guessed her card perfectly, right down to the exact suit and value.
Yumeko glanced down at the two sheets of paper, then lifted her gaze to Jun. Her lips parted a little, her breath short and uneven.
For three tense, agonizing seconds, everyone in the café thought she was about to crack.
The complete unraveling of her psychological trap—the effortless collapse of her game—seemed certain to splinter her mind.
Instead, Yumeko just threw her head back and laughed.
It wasn't a gentle, polite giggle. It was a loud, booming, utterly unrestrained roar of joy that echoed off the acoustic ceiling panels Jun had fine-tuned earlier that morning.
She slammed both hands on the counter, her face glowing with a deep, feverish, ecstatic red.
"AMAZING!" Yumeko exclaimed, her voice breaking with sheer, overwhelming joy.
"Absolutely magnificent! You didn't just counter my trap—you saw straight through the very depths of my mind!...
...Izanami-san, you're a monster!...
...A beautiful, terrifying, absolute monster!"
She leaned across the dark walnut table, paying no mind to the chips or the stakes, and seized both of Jun's hands in hers, gripping them with a frantic, trembling force.
"I lost!" Yumeko exclaimed, her eyes shining with tears of sheer joy.
"I lost completely and totally! It was the most exhilarating, terrifying defeat of my life!
So, Izanami-san... what's my favor? What do you want from me?!"
Jun glanced down at his hands, currently trapped in the chaotic gambler's grip. With a long, tired sigh, he gently slid them free from her grasp.
The heavy, dark aura vanished in a flash, and the room's icy chill melted away in the blink of an eye.
The relaxed, stylish café owner returned, rolling his shoulders and tilting his head until his neck let out a gentle pop.
"Relax, Jabami-san," Jun said with ease, pulling a fresh white towel from the shelf and leisurely wiping the counter. "I'm not about to make you cut ties with Hyakkaou or force you into servitude. That would be an administrative nightmare."
Yumeko's wild grin wavered, shifting into genuine confusion. "An... administrative nightmare? But I lost! The wager was your sanctuary against—"
"...Fool,"
"Listen, Crazy Girl... The whole point of the wager," Jun cut in, his voice easy but edged with firm resolve, "was to teach you not to gamble your entire existence on a whim in someone else's shop."
He slung the towel over his shoulder and glanced down at her, a faint, genuine smirk playing on his lips.
"Here's the deal: you and Suzui-kun will sit at table four, enjoy a proper meal, and then head out of my place quietly. No more games, no high-stakes bluffs—just a calm dinner, on the house."
Yumeko looked up at him, her mouth slightly ajar.
The fierce, chaotic storm in her burgundy eyes eased, giving way to a deep, puzzled wonder.
She had braced herself for demands of loyalty, family secrets, or complete surrender.
What she hadn't expected was that it would be nothing more than an ordinary warm meal.
"..." x3
Beside the espresso machine, Ririka exhaled a deep, trembling breath, her knees buckling slightly as she rested her back against the counter for support.
In the corner booth, Kaguya closed her eyes and pinched the bridge of her nose, feeling the intense tension finally melt from her shoulders.
Erina gave a loud, smug huff, folding her arms and turning her head aside, though the hint of relief in her smirk was impossible to conceal.
Yumeko eased back into her stool, her hands folded neatly in her lap. She glanced up at Jun—truly seeing him—her sharp, analytical mind working to make sense of the calm, undeniable clarity in his mercy.
"You're quite a peculiar man, Izanami Jun," Yumeko said, her voice returning to its polite, lilting tone.
"...Fool, I'm just a chef, in case you've forgotten, crazy girl," Jun said, turning his back to her as he pushed through the swinging kitchen doors.
"Also, you look like someone that haven't eaten a proper meal in weeks.
Hisako, prepare table four. I'm cooking the yuzu-kosho mackerel."
As Jun slipped into the kitchen, the thick tension in the dining hall melted away. The sanctuary remained steadfast.
Yumeko lingered at the counter, her gaze fixed on the vacant spot behind the walnut bar. With a gentle motion, she extended a finger and brushed the edge of the Three of Hearts resting on the felt.
She turned her head slightly toward Ryota, who was slumped against the wall, looking like someone who had just barely survived a disaster.
"Ryota-kun," Yumeko murmured, her dark eyes shimmering with quiet intensity.
"Y-Yes, Jabami-san?" Ryota stammered.
"Did you notice?" she asked, a slow, deeply curious smile spreading across her face.
"Notice... what?"
Her smile grew wider, her eyes taking on a new, almost unsettling kind of obsession.
"During that entire final hand," she whispered, her voice barely audible over the soft hum of the kitchen refrigerators.
"His heart rate didn't budge. Not a beat quicker, not even when I raised the stakes to his very life itself..." Yumeko remarked.
"So tell me, Ryota-kun... what kind of person has a heart that doesn't beat?"
