It was a dark night at the Mishima Zaibatsu headquarters, shrouded in tension that lingered heavy over the empty halls. Jin Kazama sat in his office, stoic and solitary, aware of the shadows lurking beyond the walls of his empire. He had sensed an ominous presence creeping closer for weeks. He knew an attack was inevitable—but what he hadn't anticipated was his would-be assassin: M. Bison, the tyrant leader of Shadaloo, accompanied by his ruthless enforcer, Juri Han.

The silence broke with an explosion that shook the entire building. Alarms blared, and Jin was instantly on his feet. He turned towards the shattered glass wall behind him, where the daunting figure of M. Bison levitated in the air, his red cloak flowing like blood in the wind, eyes alight with a menacing glow. Below him stood Juri, her twisted grin splitting her face as she cracked her knuckles, eager to engage.

"So, you're Jin Kazama," Bison's voice boomed, laced with sadistic pleasure. "I expected…more."

Jin met Bison's gaze without flinching. "You've overstepped, Bison. I'll make you regret it."

As Jin prepared to strike, a deeper, familiar voice called from the darkness.

"That'll have to wait, boy."

Heihachi Mishima stepped out from the shadows, his arms crossed, expression calm but deadly. His eyes flicked to Jin, his grandson, and then back to Bison. "Bison...you picked the wrong family to trifle with."

But before Jin could retort or even acknowledge Heihachi's unexpected appearance, another figure emerged from the opposite end of the hall—Kazuya Mishima, his father.

"Looks like you two need my help after all," Kazuya scoffed, arms crossed as he stepped into the light, his eyes sharp and deadly. He smirked, but his gaze was unwavering on Jin and Heihachi.

"Tch. I don't need help from you two," Jin replied, his stance tense as he eyed his father and grandfather. "But if you're here, don't get in my way."

Kazuya gave a mocking laugh. "Same goes for you, boy."

Bison watched the family with bemusement, sensing the tension thickening. "Oh, how quaint," he sneered. "A family reunion. Shall we proceed?"

Juri grinned, her eye gleaming. "I've been waiting for this! Let's see what these Mishima freaks can do."

With that, she launched herself at Kazuya, a high kick aiming for his head. Kazuya blocked her strike, their limbs colliding with brutal force. Kazuya's face twisted with a dangerous smirk.

"So, you like to kick, huh?" he taunted. "Let's see how you handle this!" He lashed out with a series of electrifying punches, his fists crackling with his Devil Gene energy.

Meanwhile, Heihachi had squared off against Bison, who smirked, amused by the old man's apparent bravery.

"Heihachi Mishima, the infamous tyrant of the Mishima Zaibatsu," Bison remarked, clasping his hands behind his back. "But I'm afraid you're out of your depth."

Heihachi chuckled, cracking his knuckles. "We'll see about that."

Bison lunged forward, throwing a Psycho-Powered punch, his fist glowing a vicious purple. Heihachi sidestepped, narrowly dodging, and retaliated with a powerful spinning kick that caught Bison off guard, sending him reeling.

Jin watched as Heihachi and Kazuya fought side by side, a rare and unsettling sight. But he couldn't dwell on it for long. Juri was back up, recovering from Kazuya's blows and preparing to attack again, this time with her foot aimed directly at Jin.

"Come on, Kazama!" she taunted, her foot slicing through the air. "Show me what makes you so special!"

Jin met her strike with a sharp block, feeling the vibration of her kick. "I don't need to show you anything," he muttered, shifting into his fighting stance. He parried her next kick, following up with a swift uppercut that forced Juri back, her grin now replaced with a scowl.

Kazuya growled at Jin, "You're holding back, boy. Quit playing around."

Jin's eyes narrowed at Kazuya. "Mind your own fight, old man."

As they spoke, Juri and Bison regrouped, their eyes blazing with excitement at the challenge before them. Bison's laughter echoed through the room.

"This is truly a rare sight," he sneered. "Family working together… You might actually be interesting opponents."

"Enough talk!" Heihachi snapped, charging forward. He executed a powerful punch that forced Bison to block, the two of them trading fierce blows. The room crackled with the power radiating from each fighter.

Jin and Kazuya moved in tandem, each instinctively covering the other's blind spots as they fended off Juri's relentless attacks. Jin threw a blazing roundhouse, which Juri dodged, only to be met by Kazuya's fierce uppercut, sending her sprawling across the floor.

Jin and Kazuya exchanged a brief glance, unspoken words shared in that moment.

Juri struggled to her feet, wiping blood from her lip. "You think I'm going down that easily?" Her eye flared with a sinister glow as she activated her Feng Shui Engine, amplifying her strength and speed.

"Not bad," Kazuya admitted. "But that won't be enough."

Jin launched himself at her with a fury, matching her speed blow-for-blow. She managed to get in a few hits, her kicks precise and deadly, but Jin's movements grew faster, fueled by his growing anger. He finally landed a devastating punch, sending her flying into a wall. Juri lay dazed but still laughed, even as blood trickled down her forehead.

Meanwhile, Heihachi and Bison were locked in a brutal exchange. Bison's Psycho-Powered attacks forced Heihachi back, but the old man refused to give an inch. With a powerful roar, Heihachi unleashed a thunderous punch, momentarily staggering Bison. Heihachi followed up with a headbutt, sending Bison crashing to the ground.

The trio regrouped, circling around Bison and Juri as they struggled to stand.

Bison wiped his mouth, his smile never wavering. "I underestimated you three," he conceded, his eyes flicking from Jin to Kazuya to Heihachi. "But this is far from over."

Jin clenched his fists, stepping forward. "It's over for you, Bison. Leave, or you won't leave at all."

But Kazuya raised a hand, stopping Jin. "No. This one's mine." Kazuya's eyes flared red, his Devil Gene power igniting as he took a step toward Bison.

With a roar, Kazuya unleashed a torrent of dark energy, slamming into Bison and overwhelming him. Bison staggered, visibly shocked by the raw power, but his composure quickly returned. The tyrant extended his hand, summoning his Psycho Power, purple energy swirling around him in a violent storm. He laughed maniacally, reveling in the chaos.

Seeing an opening, Heihachi charged in from the side, landing a crushing kick that disrupted Bison's concentration. Jin joined in, delivering a powerful punch that sent Bison reeling. With a final, combined effort, Kazuya, Jin, and Heihachi each delivered a devastating blow, their strikes perfectly synchronized, shattering Bison's Psycho Power barrier.

The combined force launched Bison through the wall, sending him plummeting from the top floor of the Mishima Zaibatsu, his fading scream echoing as he fell.

Juri, bruised and battered, limped toward the shattered window, glaring back at the Mishima trio. "This isn't over!" she spat, before retreating into the darkness.

The silence settled over them, only broken by the distant wail of sirens. Jin, Kazuya, and Heihachi stood together, breathing heavily as they looked at each other, a wary truce lingering.

"Don't think this changes anything," Kazuya said, his tone cold.

Heihachi scoffed. "Of course not."

Jin glanced at both of them, his expression unreadable. "Agreed."

As the dust began to settle in the Mishima Zaibatsu headquarters, the three men stood in silence, barely able to mask the tension crackling between them. Heihachi looked over the remnants of his shattered office—walls cracked, floors dented, and papers strewn everywhere. He clenched his fists, a disapproving scowl etched on his face.

"Unbelievable," Heihachi muttered, glancing at the destruction. "This place looks like a battlefield."

Jin, still tense and ready for another fight, took a step forward. "What did you expect, old man? Bison wasn't exactly here to negotiate."

Kazuya scoffed, looking between his father and his son with his usual air of disdain. "And yet, somehow, you're both still standing here, yammering like children," he said, arms crossed. "Isn't this what you've been waiting for, Father? A chance to settle this once and for all?"

Heihachi's eyes glinted, a smirk curling on his lips as he squared his shoulders. "Oh, believe me, Kazuya, I've been ready for that ever since you took your first miserable breath." He glanced at Jin with equal contempt. "And you, boy—you've been itching to prove yourself. You both want a fight with me, don't you?"

Jin's hands clenched at his sides, and he took a step forward, his gaze sharp and unyielding. "Yes. Let's end this, Heihachi."

Heihachi held his ground, still smirking as he looked between the two. But as the seconds stretched, his smirk faded, replaced by a look of utter disdain. He shook his head, crossing his arms.

"On second thought…" Heihachi let out a loud, annoyed sigh as he looked around his office. "This place is a disaster. I have more important things to do than indulge in this nonsense with either of you right now."

Kazuya's expression twisted, clearly irritated. "What are you talking about?"

Heihachi motioned to the broken furniture, cracked windows, and shattered walls. "Look at this mess. I'm not about to waste my energy on you two idiots in a trashed office." He turned to glare at Kazuya. "Do you have any idea how much I paid for this desk alone?"

Jin, looking visibly annoyed, shook his head. "Are you seriously more concerned about your office than finally settling things?"

Heihachi shrugged. "As foolish as it sounds, yes." He turned his back on both of them, heading toward the cabinet in the corner and sifting through a pile of papers scattered on the floor. "I'll deal with you both on my terms, not because you happen to be here after some second-rate thugs from Shadaloo decided to drop in uninvited."

"Unbelievable," Kazuya muttered, glancing over at Jin. For once, the two seemed to share a rare moment of agreement.

Heihachi didn't look back as he spoke, waving a dismissive hand at them. "Now get out. Both of you. I've had enough of your sniveling faces for one night. And don't test my patience, or I will change my mind."

Jin gritted his teeth but said nothing. He had expected many things from his grandfather tonight—a final fight, an end to their hatred—but not this. He exchanged a long, begrudging look with Kazuya, then turned and headed toward the door, his fists still clenched.

Kazuya gave a mocking smile, half-disgusted, half-amused. "You're really as senile as I always thought, old man."

"Save your breath, Kazuya. You're wasting more time than I care to waste on you." Heihachi didn't even turn around, continuing to sweep debris from his desk.

With a final glare, Kazuya followed Jin out, muttering under his breath. The doors slammed shut behind them, and Heihachi let out a sigh of relief, smirking as he straightened up, casting a look at the empty room.

"Fools," he muttered to himself, amused by his own decision to send them off. As he began tidying the papers and resetting his desk, a small chuckle escaped him. "There'll be plenty of time for that fight…when I decide it's time."
