Since the enclosed courtyard assigned to Neji's quarters possessed a training ground of adequate size, neither party saw the need to relocate. The heavy wooden gates were shut, isolating them from the rest of the Branch House.
Neji stepped into the center of the sparring ring. He dropped smoothly into the opening stance of the Gentle Fist, his right arm extended, his left hand chambered near his waist.
"Byakugan!"
The veins around Neji's temples bulged violently as his dojutsu flared to life. The world desaturated into a piercing, 360-degree X-ray schematic. Although he was years younger than the doctor and possessed a smaller physical frame, Neji's ocular advantage in a pure taijutsu spar was supposed to be insurmountable.
Kei, entirely stripped of the Byakugan's visual feed, simply leaned his cane against a nearby weapon rack. He stepped onto the dirt, his dead, milky eyes staring blankly ahead, and mirrored Neji's opening stance with flawless, textbook precision.
In the next fraction of a second, the courtyard erupted into motion.
Neji launched the first assault. He closed the distance with a burst of kinetic speed, his right palm cutting through the air like a localized guillotine, aiming a vicious, sweeping strike directly at Kei's left flank.
Kei did not retreat. He stepped into the guard, raising his left hand to perfectly intercept the incoming strike. The moment their wrists collided, Kei utilized the momentum to pivot, sweeping his own right palm toward Neji's exposed sternum.
Thwack! Thwack! Thwack!
The sharp, concussive sounds of flesh striking flesh echoed rapidly off the courtyard walls. In the span of a single breath, they exchanged over a dozen high-speed blows. To an untrained observer, the flurry of pure, chakra-less Gentle Fist forms appeared entirely evenly matched.
But within the storm of strikes, Neji was experiencing a profound, chilling shock.
After another blistering exchange of parries, Neji violently pushed off his back foot, deliberately breaking the engagement to put five yards of distance between them. He was panting slightly, his Byakugan wide with disbelief.
"How are you doing that?" Neji demanded, his icy composure fracturing. "Without the Byakugan to read my muscle tension or spatial trajectory, how can you predict the exact vector of my strikes?"
"The Byakugan allows you to see the world from a vast distance, Neji," Kei replied smoothly, slowly walking forward to close the gap the boy had just created. "But it does not allow you to view the world from a higher elevation. If you wish to perceive the true nature of a conflict, you cannot rely exclusively on your eyes."
"If you wish to keep your secrets, then keep them," Neji spat, dropping back into a low, aggressive guard. "Do not patronize me with philosophical excuses."
Kei shook his head gently. "It is not an excuse. I am simply trying to force you to examine the battlefield from an alternative perspective."
Neji abandoned the dialogue. He calculated that the only way to silence a clinical psychologist who weaponized his vocabulary was to physically break him. Once Kei was flat on his back, the patronizing lectures would cease.
Neji exhaled sharply, centering his focus. He imagined the sprawling, geometric divination circle expanding beneath his feet, locking Kei into his absolute domain.
"Gentle Fist Art: Eight Trigrams Thirty-Two Palms!"
Although they had agreed to a pure physical spar devoid of lethal chakra injections, the raw, kinetic velocity of the Thirty-Two Palms sequence was still devastating. Paired with the absolute spatial awareness of the Byakugan, Neji was a localized hurricane of strikes. He was certain that, without visual input, the blind doctor could not possibly track this level of acceleration.
Kei's serene smile remained fixed in place. He raised his hands, answering the storm with his own rendition of the Eight Trigrams.
Two palms! Four palms! Eight palms!
Neji pushed his physical limits, his strikes blurring into a barrage of afterimages. He targeted Kei's shoulders, ribs, and joints with surgical precision.
Yet, against all logical martial doctrine, Kei became an immovable object. Guided entirely by his omnidirectional sensory web, Kei read the microscopic displacements of air and the subtle shifts in Neji's center of gravity. For every lightning-fast strike Neji threw, Kei's palm was already waiting to deflect it.
As the sequence pushed past sixteen palms, the horrifying reality dawned on Neji. Kei was not just perfectly matching his acceleration; he was actively suppressing him.
Impossible. It is absolutely impossible! Neji's mind screamed in denial.
If Kei still possessed the Byakugan, Neji could have rationalized the defeat. He could have accepted that a veteran adult possessed vastly more combat experience and muscle memory. But Kei was blind. He was staring at nothing. To be systematically dismantled by a man trapped in darkness was a catastrophic blow to Neji's pride.
Driven by a desperate, stubborn refusal to concede, Neji poured every remaining ounce of his stamina into the final sequence. He roared, abandoning flawless technique in favor of sheer, raw velocity. He refused to lose his dignity to a blind lapdog of the Main House.
However, the cold, unforgiving reality of the physical world crushed his defiance. The faster Neji pushed, the faster Kei reacted.
After a final, desperate flurry of strikes, Neji found his arms violently batted aside, his guard thrown completely wide open.
Before Neji could recover his footing, the world stopped.
"Tap."
Neji froze, his breath catching in his throat.
Kei stood perfectly still, his arm extended. The tip of his index finger was resting lightly, flawlessly, against the exact center of Neji's forehead—resting directly over the Caged Bird Seal hidden beneath the boy's headband.
"Let us conclude the exercise here, Neji," Kei murmured, slowly withdrawing his hand. "Your mind is already in complete disarray. Continuing to flail about serves no clinical purpose."
Neji slowly lowered his trembling fists. An inexpressible, suffocating cocktail of humiliation, grief, and bewilderment welled up in his chest.
He punished his body relentlessly. He bled on the training posts every single day. He sacrificed his childhood entirely to the pursuit of strength, desperate to accumulate enough power to one day change his fate.
Yet, the ultimate result of his suffering? He hadn't even managed to brush the fabric of a blind man's coat. The sheer, astronomical magnitude of the gap between them was inconceivable.
"I... I lost," Neji whispered, the admission tasting like ash in his mouth.
Watching the prodigy's head bow in defeat, Kei knew that Neji's entire operational methodology was currently fracturing. The boy was questioning the very foundation of his existence. This was the precise, critical window to bypass his psychological armor.
"Tell me, Neji," Kei asked softly. "Do you understand exactly where you lost this battle?"
"Where did I lose?"
Neji slowly looked up. He expected to see a smirk of vindicated superiority on the older man's face. Instead, Kei's expression was an infuriatingly warm, gentle smile, entirely devoid of a victor's arrogance.
After a moment of bitter calculation, Neji answered. "My proficiency in the Gentle Fist forms is vastly inferior to yours. My physical speed could not suppress your parries."
"No. Those are merely the superficial, mechanical symptoms of your failure," Kei corrected, shaking his head. "Even if I had merely matched your speed, or slowly, methodically overpowered you, your guard should not have collapsed so rapidly."
Kei took a slow step forward, his voice dropping into a hypnotic, clinical cadence. "Neji, you did not lose this spar because of a flaw in your technique. You lost because of the rot in your inner self."
"Your mind is a chaotic storm. You are so entirely consumed by your rage, so desperately fixated on the immediate outcome of winning or losing a single skirmish, that you are completely blind to the true, systemic crisis looming on the horizon."
"Because your vision is so profoundly narrow," Kei warned, "when the true crisis inevitably arrives, the physical strength you have bled so heavily to acquire will be utterly useless. Your angry shouts and your fast fists might buy you a fleeting moment of satisfaction, but ultimately, they will not change the architecture of your cage."
Stopping a pace away from the boy, Kei delivered the prescription. "Right now, rather than mindlessly brutalizing your knuckles against a wooden post, you must focus entirely on elevating your psychological capacity."
Neji took a cautious half-step back, creating distance. "So, you are claiming that if I enhance this abstract 'inner power' of yours, I will miraculously achieve the freedom I desire?"
"I am a psychologist, Neji, not a deity. I do not offer absolute guarantees."
Kei folded his hands over the handle of his cane. "Life is exactly like a game of Go. A single, emotionally compromised move can result in the loss of the entire board. And reality is vastly more unforgiving than a board game, because you cannot reset the pieces, and you cannot retract a catastrophic mistake."
"Therefore," Kei concluded, "strengthening your psychological foundation allows you to consistently make the optimal, rational choices in your daily existence. Over time, those calculated choices will slowly tilt the balance of the board in your favor."
Neji stared intensely at his blind relative. The doctor's words were layered in philosophical abstraction. Neji felt as though he were grasping the very edge of a profound revelation, but the core truth still eluded him.
Sensing the boy's intense cognitive struggle, Kei understood the foundation was set. Just as he had done with Kakashi, he needed to allow the patient time to digest the trauma. Pushing harder now would only trigger a defensive rejection.
"It is perfectly acceptable if you cannot fully synthesize the lesson right now," Kei offered his customary, soothing smile. "Given your age and your lack of real-world exposure, some concepts must be physically experienced to be understood."
"Here is my clinical directive," Kei instructed. "Get a full, uninterrupted night of sleep. Tomorrow morning, you will accompany me on an excursion. Once you see the destination, you will finally understand exactly what your methodology is lacking."
"Remember, Neji. Practical application is the sole criterion for verifying the truth. We will resume our diagnostic discussion after tomorrow."
Without waiting for an acknowledgment, Kei turned and tapped his way out of the courtyard, Haru silently falling into step behind him.
Neji remained standing in the center of the training ground, his Byakugan deactivated, staring blankly at the heavy wooden gates long after the doctor had departed.
He desperately wanted to dismiss Kei as a pretentious, manipulative fraud. But the phantom sensation of the doctor's finger resting lightly against his Caged Bird Seal lingered on his skin. Today's absolute, humiliating defeat had violently proven one undeniable fact: perhaps, his current path was truly leading nowhere.
