For Kaito, the world had fractured when he was six years old.
It wasn't a gentle awakening, a graceful transition into magic. It was a trauma: a cold, dizzying immersion into a universe defined by constant, blinding data. Kaito had been a newly orphaned child then, barely old enough to tie his own shoes, clinging to the hope that the woman who had left him on the church steps might come back. The final, crushing understanding of his abandonment settled in-not through sorrow, but through the cold, stark realization that her emotional Ki signature was completely absent from his vicinity-and the world rebelled.
His eyes, once a simple brown, flared open in a terrifying burst of light.
In an instant, the cobblestones, the moss, the very air, were no longer solid objects. They were intricate, pulsating mosaics of energy. He saw the ambient mana of the Clover Kingdom like a blinding, fractal nightmare of numbers. Every breath of wind was a statistical analysis, every living thing a complex, unstable equation. His small, six-year-old brain was instantly tasked with processing the entire world—the flow of sap in the nearby tree, the residual heat mana from a passing traveler's cigarette, the precise trajectory of a falling feather.
It didn't stop. It never stopped.
The pain wasn't physical; it was cognitive. To survive the sensory overload, Kaito learned the only coping mechanism that worked: efficiency. He used the Six Eyes not to appreciate the beauty of the universe but to filter, categorize, and discard 99.9% of the noise. The constant, crushing need for absolute control became his life's discipline.
By age fifteen, the same age as the energetic mana-less idiot that now shared his squad, Kaito had nine years of practice in turning the cosmic chaos of the Six Eyes into surgical precision.
This internal discipline was evident now, standing inside a damp, geological ruin on a joint mission with the vaunted Golden Dawn. Kaito wore the Black Bulls uniform, though he always opted for the most muted, charcoal-grey tunic possible - anything to dull the attention his eyes still drew when he allowed them to focus.
The air around him was alive with visible noise: the sickly, dense purple swirls of residual Dark Triad magic, the pale blue streaks of natural ambient mana, and most importantly, the vibrant gold Ki of the proud mage standing before him.
"No, Leon, stop. You're bleeding five percent and that much compression on the lateral axis will cause a critical structural failure in T-minus 1.4 seconds. Your fear is making your Ki unstable."
Kaito sighed to himself, rubbing the bridge of his nose. He didn't voice the complete truth, of course. Leon Vermillion, the high-ranking noble on loan from the Golden Dawn, wouldn't take kindly to being informed that his structural integrity was about to give way, let alone that his underlying Ki betrayed his nervousness.
Leon was trying to blast through a section of rock that was densely packed with enchantments. He was handsome and arrogant, and at the moment, covered in sweat from the pressure of failing.
"Say something, commoner?" Leon snapped, his head whipping sharply to the side; his grimoire floated beside him.
"I said, keep going, Sir Leon," Kaito replied, his voice flat on purpose. "Your output efficiency is… manageable for this current engagement."
Leon scoffed and cast more mana than needed. The air shimmered, and a huge, spherical cluster of fire formed overhead, buzzing with unnecessary destructive force.
[SIX EYES ANALYSIS: FIRE CREATION MAGIC – BLAZING ORB ]
Total mana used: 92,000 units.
Mana Source Stability: Turbulating-8%-8% . Excessive heat generation will cause the turbulence of ambient mana.
Targeted Structural Integrity: 15,000 units needed to breach-Point Impacts.
Wasted Energy (Heat/Kinetic Scatter): 77,000 units, 83.7% Inefficiency.
Ki Signature: Leon, highly agitated, showing prideful anxiety.
The cyan overlay of metrics was a painful, ugly sight to Kaito. It was an offensive display of waste, of a mage reliant on volume instead of geometry.
Leon launched the spell. "Blaze Impact!"
The orb exploded in a deafening boom. It was loud, flashy, and ultimately useless. As the smoke settled, the passage was still blocked. The deep-seated geological mana structure had absorbed the blast. It was only a scorch mark and a minor fissure that remained. Leon stumbled back, huffing hard, visibly drained.
"Blast it! The residual barrier magic is thicker than I calculated." Leon gasped.
Kaito walked past him. "The barrier magic is irrelevant, Sir Leon. You over-pressured the wrong axis. You didn't need an explosion; you needed localized, perfect compression."
Kaito's humble, five-leaf clover Grimoire shined with a faint, almost invisible light. He didn't scream. He didn't rage. He simply reached for his mana-not to summon fire or wind, but to reinforce himself.
Reinforcement Magic. The most straightforward and direct form of magic. Mana poured not out of him, but into him, concentrating on the structural components of his right arm and fist.
[SIX EYES ANALYSIS: REINFORCEMENT CHANNELING]
Target Mana Spend: 15,000 units.
Channeling Flow: 100.0% efficient.
Mana Focus: Nano-degree concentration along the primary bones and skin of the striking point.
Kinetic Output: Equivalent to 90,000 units of focused blunt force.
Prediction: Complete, localized molecular failure at stress point.
Kaito found the exact, minuscule pressure point on the rock face-a point where the geological mana density was at its lowest. He drove his reinforced fist into the spot.
The sound wasn't an explosion but a clean, sharp snap.
The magic rock didn't blow up so much as collapse in on itself, breaking into manageable, non-magical rubble. A clear, debris-free passage opened.
Kaito dropped the Reinforcement, the faint light receding immediately.
"Fifteen thousand units," Kaito muttered, comparing the final output with Leon's starting 92,000. "Zero wasted mana."
Leon stared, his face pale with disbelief. "You… you annihilated that structure with less than a sixth of my mana."
"The trick isn't how much you use," Kaito said, looking through the new passage. "It's making every unit of mana perform its absolute, mathematically perfect function. That requires a calculation you cannot make without seeing the equation of reality itself."
The mission quickly degenerated. The more they ventured deeper, the darker the energy around them became. They found the trapped commoners, but just as they were about to head out with them, a low, ominous quake shook the ground.
A dark shadow detached itself from the wall. It wasn't rock; it was a construct of dark, corrupted magic that had been solidified into something Kaito instantly recognized as linked to the pervasive influence of the Dark Triad.
In an instant, Kaito's sensory overload had doubled. The Six Eyes gave the objective data, but the creature's presence had made his second system scream.
The Ki was fully engaged, acting as the primal alarm.
[KI ANALYSIS: IMMEDIATE THREAT LEVEL – CATASTROPHIC
Purpose: Pure, distilled malevolence, laced with an agonizing, hungry Void Ki.
Emotion: Feral rage, directed hunger.
Movement Prediction: Ultra-speed charge. Warning: Psychic interference imminent.
It moved in a weird sort of flow, not conventionally, its body mass belied by its speed. It aimed a powerful physical blow squarely at Kaito's head.
[SIX EYES ANALYSIS: ENEMY MANA]
Mana Flow: 99% channeled into its armor and density, almost no external mana.
Trajectory: V = 30m/s. Impact point predicted at Kaito's core in 0.75 seconds.
Leon's Reaction Time: Mana channel initiation in 0.5s. Spell completion in 1.3s. FATAL LAG.
"Leon! Drop the spell! Evade!" Kaito roared, his urgency driven by the certainty of the Ki of imminent death.
Leon was panicked and started a spell he couldn't possibly complete in time.
However, Kaito was already responding to the Ki's warning: he had not been using his sight to find his enemy, but rather using his Ki to sense this incoming malevolent intent, calculating with the help of the Six Eyes the perfect, minimal action necessary to survive.
He didn't jump or run. He made a movement of perfect, compressed efficiency. He channeled a tiny, lightning-fast pulse of reinforcement mana into his left leg—just enough to generate the instantaneous torque needed for a micro-pivot. He rotated his upper body 0.08 meters to the left, allowing the massive crystalline claw of the monster to shear past his ear, the wind of the passage enough to sting his skin.
Zero wasted motion. Perfect evasion.
"How…?" Leon stammered, dropping his spell and scrambling backward. "You moved before it finished accelerating!
"Ki tells me the threat is inevitable. My eyes calculate the minimal escape velocity," Kaito explained; his mind was already three steps ahead.
The golem's momentum carried it just a bit past Kaito, and in that flash of time, the Six Eyes mapped the enemy's full, stable structural equation. Its frightening speed had, for an instant, left its center of mass unstable and its magical nexus exposed.
Kaito launched the counterattack: the Ki-Reinforced Blow.
He channeled 35,000 units of Reinforcement mana, focusing it not into a general increase in strength, but into a needle-point vector aimed for the exposed nexus. More importantly, he consciously injected his own calm and controlled Ki into the flow of mana.
The Six Eyes guided the strike to find that single, microscopic point of stress. The Ki provided the subtle, internal disruption.
He didn't punch. He thrust his fingers, reinforced, like a compressed spear, into the creature's core.
The impact was silent, deep, and jarring. Kaito felt the hostile, volatile Ki of the monster violently resist the intrusion of his controlled energy. It was a battle not of sheer strength but of precision and intent. Kaito forced his pure, controlled Ki into the core, disrupting the corrupted mana's ability to maintain its form.
The creature froze, its internal equation suddenly solved, its foundation nullified. It didn't explode; it imploded. The enormous crystalline body folded in on itself, collapsing into a heap of inert, non-magical powder.
Kaito took his hand back, his pulse unchanged by such a close call with death. The six-year-old that had woken up, terrified of the world's chaos, was by now a man who used the same chaos to find perfect order.
Leon approached the pile of dust slowly, shaking his head. "That was… surgical. You're terrifying, commoner."
"It's just efficient," Kaito corrected, his eyes flashing down. He hated the word 'terrifying.' He only desired control.
The report was filed, and the commoners rescued were safely returned. At the headquarters of the Black Bulls, chaos stirred in the dining hall; Captain Yami Sukehiro stood by the railing, looking out into the forest as he smoked.
"Leon's report was verbose, but the summary was clear," Yami grunted, not turning around. "You took down a mid-level menace with a flick of your wrist and a tenth of the mana required. Good job, Kaito."
Kaito leaned against the wall, filtering out the noise of his squadmates: Asta's deafeningly enthusiastic Ki; Noelle's high-pitched, defensive Ki; Finral's cowardly, retreating Ki-it was a symphony of inefficient humanity.
"It was an efficiency problem, Captain," Kaito replied. "The creature relied on mass and speed, but its mana core was structurally weak. It only required a high-kinetic, focused delivery.
"And you used your Ki to read its intentions and its soul. That's why you survived," Yami said, finally turning, and his Dark Magic signature was a terrifyingly compressed black hole of power. "Your eyes tell you the perfect path but your Ki is what tells you the attack is inevitable. You were abandoned as a child, Kaito. That's why you cling to data—because data is reliable. But fighting requires instinct, and that's Ki."
Kaito looked down. Yami saw him with an unnerving clarity that few others did.
"The data never lies, Captain. People do. My mother did," said Kaito softly.
"She's irrelevant now; what does matter is what you do with the power she gave you indirectly," Yami said, throwing him a new mission scroll. "This is a different kind of problem. A high-priority assassination attempt in a heavily populated area, with a moving target and assassins who use high-speed, invisible thread magic. What they need is someone able to track and intercept something faster than the eye can see without causing collateral damage.
He opened the parchment. Immediately, he saw the numbers: the high likelihood of collateral damage, the sheer difficulty of predicting the thread-magic's vector.
[SIX EYES INITIAL ASSESSMENT]
Target: High mobility, complex avoidance algorithms.
Threat: Invisible, high-velocity, high-mana-density thread magic.
Required Speed Factor: x2.0 perception speed is required for a stable interception solution.
Required Attack Solution: Instantaneous, surgical, kinetic severance.
"They need perfect, split-second, predictive execution," Kaito summarized.
"They need a solution that doesn't shred half the city just to save one noble," Yami confirmed, snuffing his cigarette out. "You'll take the loud kid with you. Asta. He's mana-less, so he won't interfere with your calculations, and his Ki sense is the worst I've ever seen—but he's got the one thing you rely on: the Anti-Magic swords. If those threads are too dense for your reinforced fist, Anti-Magic is the only answer."
Kaito nodded, feeling the hum of the Six Eyes gearing up for a new test. This was his purpose: finding order in chaos.
"I understand, Captain. We'll have perfect efficiency."
"Just don't calculate so hard you forget to breathe," Yami warned. "Now get out there."
A few minutes later, Kaito found Asta doing push-ups with alarming, maniacal enthusiasm. Asta's golden Ki was simple, powerful, and overwhelmingly good.
"Hey! Kaito! Are we going on a mission together?!" Asta yelled, jumping up.
"Yes, Asta. And this mission requires absolute silence, speed, and precision. You will move exactly where I tell you, when I tell you. No yelling. No unnecessary movement. We are optimizing our output," Kaito instructed, his eyes already running spatial calculations on Asta's movements.
Asta simply grinned, his energy infectious. "Got it! I'm going to be the Wizard King, so I'll be the most efficient too! Let's go!"
Kaito shrugged into his tunic and toward the door. A boisterous, overexcited boy; Anti-Magic; and his own horrific capability to see through into the equations of life: it was a chaotic mix, but Kaito knew he'd find the perfect path through it-the minimal path. The data demanded nothing less.
