The UA library was a cathedral of silent knowledge, its towering shelves stretching toward a vaulted ceiling lost in a haze of amber shadow. It was the only place on campus where the frantic, thundering energy of Gym Gamma couldn't reach—a sanctuary of still air, the faint, comforting scent of aging parchment, and the rhythmic, distant ticking of a grandfather clock that seemed to measure time in heartbeats rather than seconds.
Sherlock Sheets sat in a secluded alcove at the very back of the West Wing, hidden behind a fortress of open textbooks, metallurgical manuals, and high-level fluid dynamics journals. A single desk lamp cast a sharp, geometric pool of light across his workstation, cutting through the gloom like a scalpel. To any student wandering by, he looked like a scholar lost in a history cram session. To Sherlock, this was a war room. His mind was a supercomputer running millions of simulations, and currently, every single one of them ended in his own structural failure.
He leaned back, his eyes tracing the flickering dust motes that danced in the lamp's glow. His body felt light, almost hollow. The high-intensity training from earlier had drained his lipid reserves, leaving his metabolism struggling to replenish the fuel needed for his Quirk. But it wasn't just physical exhaustion that haunted him; it was the data.
The doctor's warning remained etched in his mind like a carved commandment: "Rebalance. Recalibrate. Do not push the pressure. Your heart needs to find its new equilibrium, or it will simply cease to function."
"Stability is a lie," Sherlock whispered to the empty, echoing room. "The only constant is the rate of decay. And currently, my decay rate is exceeding my defensive capacity."
He looked down at his hands, resting palm-up on the mahogany table. They were steady now, the heavy bandages from the hospital finally removed to reveal skin that looked too thin, almost translucent. He had reached a threshold of 500 sheets of "Sweat Paper" today without a spike in his internal blood pressure. By all accounts, it was a victory of control. But in the cold, unyielding math of a real-world battlefield, 500 sheets were a rounding error. They were a curtain of silk trying to stop a hurricane.
He was vulnerable. He knew it. The realization was a cold stone sitting in the pit of his stomach. His Quirk was an offensive masterpiece—a sharp, versatile instrument capable of dissecting targets with the precision of a laser. But his physical shell? It was fragile. It was the "Glass Cannon" flaw in his architecture.
His Quirk was an offensive masterpiece, but his physical shell was fragile. If a high-impact projectile or a close-range brawler like Kirishima or Bakugo got past his initial screen, the "Magician" would be broken before the trick even began.
I lack a defensive perimeter, Sherlock analyzed, his mind spinning through the data of his past failures. The Nomu in the infirmary... the muscular villain at the cliff... they all breached my space because I relied on distance. I need to turn my medium into a fortress.
He closed his eyes and saw the dark, suffocating gas of the forest camp. He saw the Nomu in the infirmary, its hulking, mindless form barreling through his paper shields as if they were nothing but autumn leaves. He remembered the sensation of the muscular villain's fist—the sheer, terrifying displacement of air as a strike nearly ended his life at the cliffside.
In every one of those scenarios, the enemy had breached his "Zero Zone." He relied on distance and flight, but the moment a high-impact brawler or a high-velocity projectile closed the gap, the "Magician" was left defenseless. He was a master of the stage who had forgotten to build a cage for the lions.
"If I am touched, I break," he muttered, his pen scratching a jagged line across a notepad. "And in the National License Exam, everyone will be trying to touch the students of UA. We are the primary targets of the 'Crushing.' If I cannot survive a direct hit to my torso, my offensive output is irrelevant."
He began to analyze the physics of his current defense. When he created a wall of paper, he was essentially creating a series of overlapping planes. In theory, the friction between the sheets should dissipate force. But in practice, a high-impact strike—like a punch from Midoriya or an explosion from Bakugo—didn't just hit the paper; it traveled through it. The shockwave bypassed the material and slammed into his internal organs.
He needed a way to turn his medium into a fortress. Not just a wall, but a kinetic sink—a structure that could eat the energy of a god and turn it into a whisper.
His mind drifted to the way he produced his paper. Currently, it was a manual process directed through his hands. This was a catastrophic tactical bottleneck. If his arms were pinned, he was finished. If his hands were occupied with an attack, he was open to a flank.
The defense must be autonomous, he thought, his eyes sharpening. It must be a layer of the suit, a layer of the skin. I need to move away from the 'Sheet' and toward the 'Structure.'
He looked at a diagram of a beehive in one of his books. The hexagonal cells provided maximum strength with minimum material. If he could replicate that at a molecular level with his sweat-produced cellulose, he could create a "Living Armor." But that required a level of control over his sweat glands that he currently lacked. He needed to be able to trigger materialization from his back, his shoulders, and his chest simultaneously.
And then there is the blood, he thought, his pulse quickening.
The Crimson Paper was the ultimate defensive material. Its iron content made it as rigid as steel plate, yet it remained as flexible as silk. It was the perfect armor. But the "Blood Paper" was a poison. Every time he used it, he risked a stroke or a heart failure. He couldn't build his house on a foundation of his own life-force.
"The white paper must become the fortress," Sherlock decided, his hand tightening around his pen until the plastic groaned. "I must engineer a way to make the sweat-medium mimic the durability of the crimson-medium without the biological cost. I need to change the geometry of my survival."
He looked at the empty alcove, his mind's eye already projecting 3D models of interlocking folds and rotating cyclones. He wasn't just a student anymore. He was an architect facing a structural collapse, and he had exactly two hours to rewrite the laws of his own protection.
Sherlock pulled a clean sheet of heavy-duty drafting paper toward him and began to sketch. His pen moved with clinical efficiency, mapping out the molecular stress points of a new defensive theory. The tip of the pen danced across the page, leaving behind a trail of complex, honeycombed patterns and intricate accordion folds.
"Standard sheets are flat planes," he mused, his voice a low hum in the silence of the library. "They dissipate force across a two-dimensional surface. It's inefficient math. If I want to stop a physical strike—a punch, a kick, a falling pillar—I need depth. I need three dimensions of resistance."
The first move took shape on the page, the ink forming a dense, layered block that looked more like a piece of engine machinery than a hero's tool: Paper Art: Fortress Fold.
Instead of a wall made of hundreds of individual sheets, Sherlock envisioned a singular, massive construct composed of thousands of micro-compressed accordion folds. By weaving the paper into a high-density "spring" structure, the wall wouldn't just block an impact; it would act as a massive shock absorber. The kinetic energy of a strike would be caught in the folds, compressed, and then redistributed harmlessly into the ground or the surrounding air.
Resistant to: Strong physical impacts and light projectiles, he noted, his handwriting small and precise. But the cost... to maintain that density without using my hands as a guide...
That was the primary flaw he had to solve. Currently, Sherlock's Quirk required a degree of manual direction. He "pushed" the paper from his palms like a magician performing a sleight of hand. If his hands were occupied or restrained, his defense collapsed. He needed a way to trigger materialization from the sweat glands across his entire body—shoulders, back, chest—and command them through neural impulse alone.
He shifted his focus to the second problem: the "Zero Zone."
If an enemy managed to get within three meters—the "In-Fight" range—his long-range "Lattice" and "Snap Blast" attacks were far too slow and unwieldy. He needed a deterrent—a constant, autonomous "no-fly zone" of razor-sharp geometry that lived on his skin.
Paper Art: Razor Cyclone.
The sketch showed a swirling vortex of thin, serrated paper strips, each no longer than a finger. By utilizing the ambient air currents generated by his own movement and a micro-kinetic "tether," he could create a localized cyclone that orbited his body in a tight, three-dimensional sphere. It wouldn't be a solid shield like the Fortress Fold, but a "meat grinder" of high-velocity paper. Anything that tried to grab him or punch him would have to pass through a thousand rotating blades first.
Uses: Defense against multiple enemies. Prevention of grappling and close-range suppression, Sherlock wrote. He paused, his pen hovering over the paper. Weakness: Does not protect against very strong projectiles. Ineffective against highly durable opponents like Kirishima's 'Unbreakable' or heavy-caliber sniper fire. It is a screen, a deterrent, not a bunker.
He stared at the two moves. One was a shield of iron-like density; the other was a cloak of blades. Together, they formed the beginning of a true defensive architecture. But to make them real, to make them work without killing himself, he needed a conduit. He needed a suit that wasn't just clothes, but an extension of his nervous system.
Move 1: Paper Wall: Fortress Fold
The Theory: Instead of breaking under impact, the "Fortress Fold" would compress and expand, absorbing the joules of a punch or a projectile and distributing the force across the entire surface area.
The Utility: It would be virtually impervious to light projectiles and blunt force. It was the "Shield of the Magician."
Move 2: Razor Cyclone
The Theory: By manifesting thin, serrated strips of paper and rotating them at high velocity using a localized thermal updraft (generated by his own body heat and kinetic friction), he could create a "no-man's land.
"The Utility: A whirling vortex of thousands of paper blades. It would act as a passive defense, shredding anything that tried to touch him while he focused on long-range calculations.
Sherlock closed his eyes, visualizing the microscopic architecture of his own biology. He didn't just want to "make" paper anymore; he wanted to engineer it at a cellular level.
The sweat is the medium, he mused, his mind diving into the molecular void. But the strength of the paper isn't determined by the volume of the sweat. It's determined by the density of the cellulose bonding.
He began to exert a minute, high-frequency vibration through his palms. He watched as the sweat didn't just pool—it began to shimmer, the molecules forced into a tight, crystalline lattice before they even left his pores. The resulting sheet that emerged was different from anything he had produced before. It wasn't the matte white of standard printer paper; it had a dull, metallic luster, like brushed aluminum.
He gripped the small square between his fingers and tried to tear it. It didn't budge. He applied more pressure, his knuckles whitening. The paper remained perfectly rigid.
Molecularized Sweat Paper, Sherlock categorized, a ghost of a smile touching his lips. By controlling the bonding at the moment of excretion, I've increased the tensile strength by 300%. It's thinner, lighter, and yet... it has the structural integrity of a Kevlar weave.
This was the "Fortress Fold" in its infancy. If he could produce thousands of these molecularized sheets and interlock them into the compressed accordion structure he had sketched, he wouldn't just be making a wall. He would be creating a portable bunker.
But then, his thoughts drifted to the dark shadow in the corner of his mind.
He looked at the faint, blue veins tracing the underside of his wrist. Beneath that thin layer of skin flowed the Crimson Medium.
He remembered the weight of it. The way the blood-based paper didn't just resist impact—it hungered for it. The iron in his blood made the paper conductive, heavy, and terrifyingly sharp. If the molecularized sweat paper was a shield, the Crimson Paper was an executioner's blade.
It is the superior variable, Sherlock admitted, his voice a low whisper in the empty library. The sweat paper is limited by my hydration and lipid count. But the blood... the blood is fueled by the very heart that pumps it. It is faster. It is more responsive to my neural impulses. It is, quite simply, more powerful.
He realized then that he couldn't just treat the Crimson Paper as a "panic button." If he truly wanted to survive the coming storm, he had to learn to master it. He had to learn how to bleed with precision—to use micro-amounts of blood to reinforce his sweat paper, creating a "Composite Medium" that offered the best of both worlds.
But not today, he reminded himself, feeling the rhythmic, slightly fragile throb of his heart against his ribs. The doctor's mandate is absolute. If I trigger a blood-pressure spike now, I won't make it to the exam. I must wait. I must master the architecture of the sweat before I invite the chaos of the blood.
Sherlock checked his watch. The two-hour window was closing. He reached for his encrypted smartphone and dialed the private line to the Sheets Estate.
The connection was instantaneous.
"Sherlock," Arthur's voice came through. It wasn't the voice of the Director today. It was lower, gravelly with a weariness that Sherlock rarely heard. "It's late. Or early, depending on which side of the exhaustion you're on."
"It's both, I suspect," Sherlock replied, leaning back and rubbing the bridge of his nose.
There was a long pause. Usually, their conversations began with a report—grades, performance metrics, logistical requirements. But the air in the library felt different tonight. The shadows seemed longer, and the memory of the blue fire in the forest felt uncomfortably close.
"How is your health?" Arthur asked suddenly. The question wasn't framed as a medical data point. It was hesitant, almost fragile. "The doctors at the hospital... they were very specific about the damage to your cardiovascular system. They said you were lucky to be standing, let alone training."
Sherlock looked at his pale hands, the skin still sensitive where the IV drips had been. "My heart is... recalibrating. There is a persistent ache when I move too quickly, and my stamina has plummeted. But I am stable. I am following the protocols."
"Are you?" Arthur's voice sharpened slightly, though not with anger. "Because I know you, Sherlock. You don't follow protocols; you rewrite them to suit your needs. I've been staring at the reports from UA. You're pushing yourself. Why?"
"Because the world doesn't care about my recovery time," Sherlock said, his voice quiet. "The License Exam is coming. If I enter that stadium as a 'recovering patient,' I'll be eliminated in the first five minutes. I can't afford to be a liability to my class. Not after Kamino."
Arthur sighed, a sound of heavy resignation. "You've changed, Sherlock. You used to talk about 'liabilities' as if they were numbers on a ledger.
"I care about the result," Sherlock countered, though the lie felt thin even to his own ears. He cleared his throat, shifting the topic to the reason for the call. "Father, I need a new set of equipment. Specifically, the gloves."
Sherlock said, his gaze falling on the sketches of the Tactical Sanguine Gloves. "Those were prototypes. They were meant for a boy playing at being a hero. I need something professional. Something that can handle the sheer friction of high-velocity materialization."
He tapped the blueprint. "I need them to be reinforced with a carbon-fiber weave that can dissipate heat. I need the gloves to act as a catalyst—a direct conduit that speeds up the bonding process of the paper as it leaves my skin. I need them to be stronger than anything the school's support lab can provide."
Arthur was silent for a moment. Sherlock could hear the faint sound of a pen tapping against a desk on the other end.
"I can do that," Arthur said finally. "The Sheets Engineering Group has been working on a new tactile alloy for search-and-rescue drones. It's incredibly durable and light. I can have the lead engineer, Dr. Arisaka—you remember him from the summer galas—start on a pair for you tonight. But Sherlock... there's a catch."
"A catch?"
"The gloves are only one part of the equation," Arthur said, his tone turning into that of a seasoned strategist. "If you're going to be generating that kind of force, your current suit will tear itself apart. The kinetic feedback alone would bruise your arms to the bone. You need a full-body overhaul. A suit that integrates with the gloves to distribute the stress."
Sherlock looked at his sketches of the Mark II suit. "I know. I've already designed the blueprints for the reinforcement plating and the moisture-wicking base layer."
"I saw them," Arthur said. "But my team... they're engineers for industry and aerospace, Sherlock. They're brilliant, but they don't understand the 'chaos' of a hero's movement. Making a suit that fits your specifications, that moves with you without restricting your Quirk... that takes months of tailoring and field testing. We don't have that time. The exam is in two weeks."
Sherlock frowned. The logic was sound. His father's team could build the tech, but they couldn't build the hero.
"I know someone," Sherlock said, a vision of pink hair and chaotic goggles flickering into his mind. "There is a girl in the Support Course here at UA. Mei Hatsume. She doesn't care about industrial standards or aesthetic polish. She only cares about 'babies'—her inventions. She works at a pace that defies standard manufacturing timelines."
Arthur laughed, a rare, genuine sound of amusement. "A student? You're trusting the heir to the Sheets legacy to a student's workshop?"
"She's a genius, Father. A chaotic one, but a genius nonetheless. If I provide the materials your team produces—the alloy, the carbon weave, the sensors—she can integrate them into a suit in a fraction of the time your department would take. She understands the 'geometry' of combat."
There was a pause. Sherlock could almost see his father weighing the risk. On one hand, the prestige of the Sheets Engineering Group; on the other, the brutal efficiency of a UA prodigy.
"Fine," Arthur said. "I'll have Arisaka courier the raw components and the finished gloves to the UA gates by Friday morning. I'll send the digital specs to your school's server so this... Hatsume girl... can read the data. But Sherlock?"
"Yes?"
"Don't break yourself before the exam," Arthur said, his voice dropping to a whisper. "Your mother... she always said that the strongest paper is the one that knows when to bend. You've spent your life trying to be as rigid as a board. Try to remember that you're human. I'd rather have a son who failed an exam than a son who died trying to be perfect."
Sherlock felt a lump in his throat that no amount of logic could dissolve. "I'll... I'll keep that in mind, Father. Thank you."
"Goodnight, Sherlock."
"Goodnight, Father."
The line went dead. Sherlock stared at the screen for a moment, the weight of the conversation settling over him. It was the most genuine exchange they had ever had—no business, no percentages, just a father's fear and a son's ambition.
He stood up, the exhaustion finally starting to seep into his bones. He gathered his blueprints, rolling them into a tight cylinder. The two hours were up. He had the backing of a multi-billion dollar engineering firm and the promise of a gear upgrade that would turn him into a fortress.
Now, he just had to find a certain pink-haired girl in the Support Lab and convince her to help him build a masterpiece.
He stepped out of the library, the cool night air of the UA campus hitting his face. The "Magician" had his resources. The "Architect" had his plan.
"Time to build a legend," Sherlock whispered.
He turned his collar up against the wind and headed toward the Support Course workshops, the silhouette of his trench coat disappearing into the shadows of the walkway. The stage was set, and the first fitting was only a heartbeat away.
Chapter 48: The Support Lab Chaos? Sherlock enters Hatsume's workshop and has to survive her "enthusiastic" testing methods while they build the Moisture-Conduit Suit. Would you like to see Sherlock's reaction to Mei's chaotic energy?
