The courtyard exploded into dust as the descendant of the Monkey King made his first move.
Bikou initiated with a blindingly fast, sweeping strike, his ornate staff extending in mid-air to generate massive centrifugal force. Jin didn't even attempt to dodge. He squared his shoulders, his arms instantly coating in the pitch-black sheen of Armament Haki layered over the jagged, rock-like density of his hardening quirk.
*CLANG!*
Jin caught the staff with his bare hands. The resulting kinetic shockwave cratered the ground beneath them, sending spider-web fissures racing across the academy courtyard.
Jin didn't let go. Yanking the staff with terrifying force, he pulled Bikou directly into the path of a brutal, roaring right hook. Bikou didn't panic. Using the momentum of the pull to his advantage, the Yokai shifted his weight, pivoted smoothly under the massive fist, and drove the butt of his staff hard into Jin's ribs, following up with a blinding flurry of palm strikes to Jin's chest. Jin barely flinched, absorbing the blows with a feral grunt before lunging forward with a crushing, linear knee strike. Bikou lightly vaulted off Jin's rising knee, flipping backward to land flawlessly on his feet ten yards away.
In that second of contact, a silent, high-speed tactical analysis occurred between the two fighters.
*He's a monster,* Bikou realized, feeling the recoil vibrate up his staff. *His physical density is absurd. A direct, blunt-force battle against him would be an endurance game; something tells me I could lose it. But... he fights like a feral beast. His movements are linear and predictable. He relies entirely on his regenerative durability to tank hits rather than avoid them.*
Simultaneously, Jin's Sharingan meticulously analyzed Bikou's footwork. The monkey yokai possessed perfect, uncanny balance. Instead of blocking Jin's kinetic force outright, Bikou was constantly shifting his center of gravity, absorbing and redirecting the momentum.
Realizing brute force wouldn't easily break the stalemate, Bikou shifted tactics. He began utilizing his superior martial arts. As Jin threw a wild, feral hook, Bikou used his staff to pole-vault directly over the heavy strike, landing lightly behind Jin to deliver a punishing kick to his blind spot.
Creating distance, Bikou reached up, plucked a handful of hairs from his head, and blew on them. The hairs glowed with senjutsu, transforming mid-air into dozens of Yokai clones.
The clones swarmed Jin from all sides, turning the one-on-one duel into a chaotic, overwhelming brawl.
Jin was suddenly backpedaling. He was taking hits from every angle—staff strikes to the ribs, sweeping kicks to the knees, punches to the jaw. His regenerative factor and hardened skin kept him alive, but the sheer volume of perfectly executed martial arts was pushing him back.
He needed to analyze the clone patterns to find the real Bikou. He needed to create distance, weave hand seals, and utilize Ninjutsu to clear the board.
But as Jin tried to step back, he encountered a massive, paralyzing internal problem.
*His body refused to listen.*
The integrated Wolverine template—a lifetime of feral, berserker fighting instincts—was violently overriding his tactical intentions. Every time Jin's intellect told him to retreat and weave a hand seal, the Wolverine instinct screamed at him to lunge forward, tank the damage, and tear the enemy's throat out with his claws.
It was a severe mental block. The brawler style that had served him so well against mindless dragons and arrogant magicians was now actively hindering him against a highly skilled, adaptive martial artist.
Exploiting Jin's predictable, feral lunges, the real Bikou seamlessly slipped under Jin's heavy guard. Bikou channeled a massive surge of natural senjutsu into his fist.
*Bam!*
Bikou landed a devastating, concentrated punch directly into Jin's gut.
The sheer force of the blow lifted Jin off his feet. He was sent skidding violently backward across the rubble, his heavy boots carving deep, smoking trenches into the concrete while his body remained locked in its jagged, hardened form.
Jin came to a halt, kneeling in the rubble. Puking blood.
Bikou casually rested his staff on his shoulders, looking down at the human. "Looks like that's all you have," the monkey yokai taunted, a disappointed smirk on his face. "Your body and your raw instinct have carried you this far. But in front of a capable martial artist, those instincts can be fooled. And I will break your body today."
Jin stared at the ground. He realized his fatal flaw. He couldn't blend the templates in a fight of this caliber. Mixing oil and water was leaving him compromised. To fight Bikou, he had to lean entirely into Itachi's abilities.
Then Jin did what he does best: he has a solution, and he commits to it. Jin fully committed to the solution. With an act of willpower, he forcefully stopped listening to Wolverine, locking the screaming, feral beast deep into the recesses of his brain. It created a strict dichotomy: he could only fight as a feral brawler *or* a tactical ninja at one time, preventing the instincts from bleeding together.
Jin slowly stood up. He took a long, steadying breath.
The jagged, hardened skin was completely dispelled, returning to smooth, normal flesh. His chaotic, hunched, feral posture vanished. In its place, Jin adopted a perfectly still, relaxed, and lethal shinobi stance.
He was now completely focused on the Itachi template and his ability ,ready to make them his.
Seeing Jin drop his armor, Bikou charged in to finish the job.
Jin's Sharingan spun. He caught Bikou's gaze for a fraction of a millisecond and instantly cast a high-level Genjutsu—*Demonic Illusion: Burning Paper Body*.
Bikou's vision warped. He suddenly found himself trapped in a void, his body seemingly turning into paper and combusting into black flames.
But Bikou simply smirked. His eyes suddenly glowed with a fierce, blinding golden light—the legendary *Fiery Golden Eyes* inherited directly from Sun Wukong. Capable of seeing through all deceptions, he saw right through the illusion and dispelled the Genjutsu instantly with a burst of Yokai aura, shattering the fake reality like glass.
"So you do have the tricks!" Bikou laughed, summoning fifty more monkey clones and commanding them to rush Jin from all sides.
Jin didn't panic. He calmly raised his hands, weaving a single, precise hand seal.
*Shadow Clone Jutsu.*
In a puff of smoke, Tens of Jin clones appeared. But the quality difference was immediately apparent.
While Bikou's clones fought with wild, individualistic martial arts, Jin's Shadow Clones fought with terrifying, unspoken coordination. Moving with liquid grace, they engaged the monkey horde.
Jin's clones unrolled small sealing scrolls from their pockets. In puffs of white smoke, sleek katanas and kunai materialized in their hands. They moved in perfect unison, covering each other's blind spots effortlessly. When a Bikou clone swung a staff, a Jin clone parried it with a katana, while another Jin clone seamlessly slid underneath to deliver a fatal kunai strike.
The Jin clones used razor-thin wire strings to trip Bikou's clones mid-air, expertly throwing kunai rigged with explosive tags into the center of the monkey formations to break their ranks. When a Bikou clone managed to land a lethal strike on a Jin clone, there was a *poof* of smoke—the *Substitution Jutsu*—leaving only a shattered log in its place while the real clone struck from above.
The battlefield became a high-speed game of 4D chess. Every move was a feint.
The real Bikou, frustrated by the immaculate defense, spotted an opening and drove his staff straight through what he thought was the real Jin's chest.
Instead of drawing blood, Jin's body instantly dispersed into a massive flock of black crows—the *Crow Clone Jutsu*.
The crows swarmed Bikou, their flapping wings and sharp beaks blinding him for a crucial fraction of a second. As Bikou swung his staff to clear his vision, he realized his fatal mistake.
While the clones had been fighting, they had secretly wired the entire battlefield with nearly invisible ninja wire.
Standing perfectly still atop a ruined concrete pillar, the real Jin held the master wire between his fingers. He gave it a sharp pull. The battlefield instantly tightened. The razor-thin wires snapped taut, wrapping around the real Bikou and his remaining clones, trapping them in an inescapable steel web.
Jin's hands blurred through a final sequence of seals. *Rat. Tiger. Dog. Ox. Rabbit. Tiger.*
*"Fire Style: Dragon Flame Jutsu."*
Jin exhaled a massive, hyper-pressurized line of fire that traveled straight down the master wire. The flames raced across the web, engulfing the trapped Bikou in a localized, roaring inferno. Jin had completely out-thought, out-maneuvered, and prevailed over the monkey's tricks.
The flames slowly died down, leaving a thick cloud of grey smoke hovering over the scorched courtyard.
Jin stood atop the pillar, his breathing steady, waiting for the dust to settle.
As the smoke cleared, a golden light pierced the gloom. Bikou was still standing. He was breathing heavily, some of his fur charred black, yet he was entirely encased in a magnificent, glowing suit of ancient golden chainmail.
Bikou cracked his neck, spitting a glob of soot onto the ground. A wide, battle-crazed grin split his face. "Not bad, human," Bikou laughed, spinning his staff as he readied himself for Round 3. "Not bad at all."
Jin looked down at the armored Yokai. The three tomoe in his crimson eyes began to spin furiously. They blurred together, shifting and reshaping, connecting into a terrifying, three-pointed pinwheel design.
The Mangekyou Sharingan had awakened.
