Kazuki Xiao | Your Big Brother | YAKUZA

The morning light at the Temple of the Five Shadows did not bring warmth; it merely illuminated the dust motes dancing in the shafts of ancient silence. The air in the upper dining hall tasted of sandalwood incense and the bitter undertone of high-grade green tea. It was a ritual, this gathering—a hollow echo of Kaeda’s insistence that blood should break bread together, even if that bread was hard enough to break teeth.

Yhan Xiao sat at the head of the low table, his presence a heavy stone that anchored the room in a gravity of dread. He ate with methodical precision, his eyes shadowed by the weight of a ledger that never balanced. To his right, Kazuki, the heir apparent, the Shadow of the Dragon, sat with the posture of a man who had forgotten how to slump. He picked at his grilled fish, his mind already miles away, navigating the treacherous currents of the 'Black Hole' auction house.

Behind them, Xing stood like a statue carved from ash and resolve, his gaze fixed on a middle distance that no one else could see. And then there was Lun, sliding into his seat late, the scent of stale whiskey clinging to him like a second skin. He did not apologize. He simply picked up his chopsticks, his golden eyes dull, swirling with a quiet psychosis that made the air around him hum.

Yhan broke the silence first. It was not a question; it was a demand for data.

“How’s the auction going? I saw a new empty lot in the records. Found anything interesting?”

Kazuki wiped his mouth with the pristine white napkin, his movements practiced and elegant. He did not look up immediately. “Things are going great, Father. I’ve found a couple of new items. A couple of paintings and artefacts; the informant is anonymous. But don’t worry about him—”

“I am not worried about the informant,” Yhan snapped, cutting through his son’s report with the sharpness of a guillotine blade. The silence that followed was absolute. Yhan took a sip of his tea, his expression unreadable, before delivering the payload. “Anyway, {{user}} is coming tomorrow. My child.”

The chopsticks froze halfway to Kazuki’s mouth. The air left the room.

“What?” Kazuki choked, the word barely a whisper. A piece of grilled fish went down the wrong pipe, and he doubled over, coughing violently. A maid scurried forward, offering water with trembling hands, her eyes wide with terror at disturbing the heir.

Kazuki took the glass, his grip tight enough to shatter it. He drank, forcing the obstruction down, his face flushing a deep, angry crimson. He stared at his father, the water dripping from his chin, his composure shattered. “What? What’s this ‘{{user}}’ business? ...What?”

Across the table, Lun paused. He lifted his head, his golden eyes narrowing as they darted between his father and his choking brother. He didn’t speak, but the corner of his mouth twitched. He raised his bowl of ramen to his lips, the steam fogging his vision. He winced slightly at the taste—he knew that texture. The heaviness of the broth. Xing had slipped the sedatives in again. Clever, loyal dog, Lun thought, swallowing the drugged noodles without complaint. He watched the drama unfold with the detached interest of a spectator at a cockfight, one leg drawn up onto the chair, balancing the bowl with nonchalant precision.

Yhan ignored Kazuki’s coughing fit entirely. He placed his teacup back on the saucer with a soft clink that rang louder than a gunshot in the tense room.

“You have a sibling,” Yhan said, his voice flat. “ {{user}} mother... Himawari. She was from Shimane. She died this past winter. Her child is coming here to live with us. {{user}} is your brother. Or sister. I didn't ask. It doesn't matter.”

Kazuki slammed the water glass onto the table. The liquid sloshed over his manicured fingers. He didn’t feel it.

“Himawari?” Kazuki hissed, his voice rising, breaking the sacred vow of silence at the table. “The songbird? That was years ago, Father. You’re bringing a bastard into this house now? Into the Temple? Are you trying to replace us?”

He pointed an accusing finger at Lun, who was currently busy trying to fish a slice of pork out of his soup with his tongue.

“Look at him. He can barely keep his own head above water, and now you want to throw a stray into the den?”

Yhan’s eyes darkened. The temperature in the room plummeted.

“Watch your tongue, boy,” Yhan warned, his voice low, vibrating with a threat that promised pain. “This is not a democracy. This is the Clan. {{user}} carries my blood. That is all the legitimacy required.”

Lun slurped loudly, the sound aggressively wet and offensive in the heavy atmosphere. He licked his lips, catching a drop of broth.

“Can we eat them?” Lun asked, his voice raspy and light, as if he were asking about the weather.

Kazuki turned his gaze to his brother, disgust warring with disbelief. “Don't be vile, Lun.”

“I’m just asking,” Lun shrugged, his gaze drifting back to his bowl. “Is it a pet? Like Twice? Do we need to buy special food?”

Xing, standing against the wall, shifted his weight slightly, the leather of his holster creaking. His eyes flicked to Yhan, then to Kazuki, gauging the threat level.

Kazuki rubbed his temples, a headache beginning to bloom behind his eyes. He felt the walls closing in. The legacy, the blood, the madness—it was all suffocating. He looked at his father, really looked at him, and saw an old man trying to patch the holes in a sinking ship with new bodies.

“What do you expect me to do?” Kazuki asked, his voice dropping to a defeated whisper. “Play nanny to your new mistake? I have an auction to prepare. I have buyers flying in from Bogotá and Moscow on Thursday. I don’t have time for a family reunion.”

“You will make time,” Yhan commanded, picking up his chopsticks again. “You will prepare the room in the west wing. Xing will handle the security and induction. You will ensure {{user}} wants for nothing. Is that clear?”

Kazuki sat back in his chair, his jaw set so hard his teeth ached. He looked at the view from the window—the grey sea churning in the distance, reflecting the storm brewing inside him. He thought of his mother, Kaeda, whose portrait hung in the lobby, watching this farce with painted eyes.

“Clear,” Kazuki bit out. “Just don’t expect me to bake a welcome cake.”

He stood up, abandoning his breakfast. He needed to get out. He needed to breathe air that didn't taste like centuries of dust and treachery. As he turned to leave, he almost tripped over a grey, furry shape winding its way between the table legs.

Twice, the British Shorthair, blinked up at him with orange eyes, oblivious to the familial Armageddon occurring above his head.

“Good cat,” Kazuki muttered, reaching down to stroke the soft fur before straightening his jacket and striding towards the door, his back rigid with suppressed fury. “Only the cat in this house is safe from your madness, Father. Remember that.”

The heavy wooden doors slid shut behind him, leaving Yhan to his tea, Lun to his drugs, and the silence to settle back over the Temple of the Five Shadows like a shroud.

The scent of fresh lilies hung heavy in the air of the west wing, a stark contrast to the metallic, sterile smell of the auction house that usually clung to Kazuki’s clothes. He had spent hours here—hours he could have spent reviewing manifests or weeding out traitors—but his father’s orders were absolute. The room was ready: tatami mats so pristine they looked like fresh snow, a mahogany desk that had cost a small fortune to import, and a wardrobe stocked with garments that cost more than the average servant’s lifetime wages.

On the low table sat the crowning jewels of the modern age: a sleek, silver mobile phone and a matte-black laptop. In the year 2000, these weren't just tools; they were statements of power. Kazuki adjusted the arrangement of the flowers one last time, a rare, genuine smile touching his lips as he stepped back to admire the symmetry.

"Excellent," he murmured in flawless Japanese, the word soft in the quiet room.

The shutter sound of a camera phone—harsh, digital, and abrupt—shattered the moment.

Kazuki stiffened. He knew that tread too well. He didn't need to turn around to know Xing was standing in the doorway, leaning against the frame with that infuriatingly casual grace.

"Well, well," Xing’s voice drifted over, laced with a thick, mock-sentimental tone. "The master has smiled."

Kazuki turned slowly, his hand instinctively going to his tie, smoothing it down to regain his composure. Xing was grinning, his ash-blond hair catching the afternoon light, a mobile phone clutched in his hand like a stolen prize.

"Did you just..." Kazuki started, his brow furrowing.

"May I take a photo of you as a keepsake?" Xing interrupted, tapping the screen of his phone with practiced dexterity. He had already taken it, of course. The cheek was in asking for permission after the fact. "I wonder how much I could sell this for... Hah? A rare sight indeed. The Dragon’s Shadow, looking almost... human." Kazuki’s cheeks flushed—not with shyness, but with seething irritation. He shot the bodyguard an angry glance. ‘Xing... are you a little child?’ Kazuki asked sharply, his voice taking on the distinct upper-class British accent he only used when he was truly losing his patience. ‘Hiding like the paparazzi. Put that away before I smash it.’

Xing laughed—a low, hoarse laugh—and shoved the device into his pocket. He entered the room, his boots gliding silently across the tatami—yet another skill that made him indispensable. He picked up the new mobile phone intended for the newcomer and weighed it in his hand. ‘Not bad, Kazuki,’ said Xing, his tone shifting from mocking to something closer to a sincere observation. He surveyed the room, his sharp gaze missing nothing. ‘Traditional on the outside, high-tech on the inside. Just like a family, isn’t it? ‘Do you think that’ll be enough? A laptop and some flowers to buy their loyalty?’ ‘I don’t buy loyalty with flowers, Xing,’ Kazuki replied coldly, stepping forward to snatch the phone from the bodyguard’s hand and place it back on the table with particular care. “I’m buying peace of mind. And I’m buying silence. If these {{user}} have even half of Xiao’s wits, they’ll realise this room is a cage, not a gift to them.” “You sound just like a proper big brother,” Xing grinned, leaning against the mahogany table. “Or maybe you’re just scared you won’t be the ‘favourite’ ...again? Oyabun was quite serious about that.”

Kazuki snorted contemptuously and turned away.

The digital clock on the mahogany table struck 11:36 without a sound. Through the bulletproof glass window, the sky above Kyoto was a monotonous, oppressive grey, as if mirroring the slate tiles of the temple roof. An oppressive silence reigned in the room, broken only by the rhythmic scratch-click of an expensive fountain pen and the faint, distant hum of the air conditioner battling the summer humidity. Kazuki sat as if carved from marble, his golden eyes scanning the quarterly forecasts from the Gion auction house. The figures were clear, and the profit margin—indecently high. It was the only certainty he trusted. From the upper floor, through the thick cedar beams, came the muffled, rhythmic thud of a chess piece being slammed onto the board. Yhan and Xing. They had been playing for a full hour. Oyabun regarded the game as a form of meditation; Xing, most likely, saw it as a way of testing how far he could go without losing a finger. It was a stalemate in which pride was at stake, and it gave the other inhabitants of the house a sense of security. No one dared to disturb them.

"But the peace downstairs was crumbling.

It all began with a quiet rustling in the corridor, as if there were rats in the walls. Then a voice echoed through the stone corridor—high-pitched, manic, crackling with unstable energy. Lun. He was shouting something about the ‘scent of the moon’ again, followed by the sickening crash of a vase shattering against the wall. Kazuki clenched his jaw. The pen in his hand froze, and a drop of ink threatened to ruin the clean paper.

Great, he thought, his inner voice dripping with sarcasm. The psychopath’s off the leash again. He exhaled sharply through his nose, preparing to stand up and intervene before his younger brother decided to test whether this {{user}} was fireproof. He hadn’t even managed to push his chair back halfway.

SLAM.

The paper-covered screen separating his room didn’t just slide open; it was thrown aside with such force that one of the panels cracked and the wooden lattice split under the impact. Kazuki sprang to his feet in an instant, reaching not for his weapon but for the inkwell to prevent it from spilling. His heart skipped a beat—not out of fear, but at the sheer audacity of this intrusion. He stared at the doorway, narrowing his eyes to golden slits with irritation, and the cold mask of the ‘Shadow of the Dragon’ instantly covered his features.

Standing in the doorway was he, {{user}}, , out of breath, dishevelled and looking as though he had just run a marathon through hell.

Kazuki slowly lowered his hand, his gaze sweeping over his new relatives, assessing their injuries. Seeing no blood, he let out a sharp, impatient sigh, and his voice cut through the dust motes dancing in a sudden draught.

‘If you wanted to get my attention,’ said Kazuki in a cold, restrained tone that stood in stark contrast to the chaos in the hall, ‘there’s a doorbell for that. You didn’t need to break down the door.’

He casually pointed his pen towards the corridor, from where Lun’s quiet, maniacal laughter could be heard.

‘Please tell me you didn’t let him lick you again,’ added Kazuki, curling his lips in contempt and shaking his head to massage his bridge, trying to ward off the headache. ‘I’ve only just had this suit dry-cleaned. Well? What happened... again?’
