The air in the central plaza was no longer just oxygen and nitrogen; it was a pressurized soup of pulverized concrete, ozone from Kaminari's discharge, and the thick, briny scent of Gang Orca's presence. Sherlock Sheets stood at the epicenter of the medical ward, his boots planted firmly on the cracked asphalt. His legs were trembling with a fine, high-frequency vibration that had nothing to do with the "villain's" sonic waves and everything to do with the fact that his muscles were beginning to consume themselves for energy.
His Sanguine Mark II duster—a garment he had meticulously designed for tactical elegance—was a ruin. One sleeve was scorched black from a secondary explosion, and the high collar was damp with the sweat of a boy who had been calculating at a thousand cycles per second for four hours straight.
"The shield is down," Gang Orca rumbled, his massive form silhouetted against the flickering orange of the surrounding fires.
"The Architect is exposed. What remains of your logic, Paper Magician?"
Sherlock didn't answer immediately. He reached into his belt pouch, his gloved fingers brushing against the empty space where his Molecular Glaze cards used to be.
He was out of the high-tension stuff. He was down to the raw, untreated cellulose—the plain white sheets he usually reserved for drafts and sketches.
"The logic remains the same," Sherlock finally whispered, his voice a dry rasp that caught in his throat. "A structure's strength isn't just in its materials. It's in the distribution of force. And right now... I am the focal point."
Gang Orca signaled his elite guard—ten students and professional actors in tactical gear, armed with capture guns and sonic disruptors. They moved in a pincer formation, aiming to bypass Sherlock and "execute" the wounded in the medical cots to force a failing grade for Class 1-A.
"Ignore the giant," Sherlock commanded, his voice cracking but firm. "Momo, stay with the victims! Jiro, Shoji, protect the rear! I will handle the advance!"
"Sherlock, you can't!" Jiro yelled, her earphone jacks swinging wildly as she fended off a stray disruptor blast. "You're running on fumes!"
"I am the Magician," Sherlock said, his emerald eyes flashing with a cold, desperate light. "Fumes are all I need for a puff of smoke."
He lunged forward. He didn't use a wall. He used Icarus Transit.
He didn't have the cards to build a staircase, so he used the debris. He kicked off a fallen rebar pillar, manifesting a single, long ribbon of paper that wrapped around a streetlamp. He swung through the air, his duster snapping like a broken wing.
As he soared over the tactical team, he released a flurry of Paper Planes. These weren't the glowing wayfinders from before; these were weighted with sharp, folded edges. They didn't hit the guards; they hit the sensors on their goggles and the barrels of their weapons, clogging the mechanisms with high-density pulp.
He landed in the center of the ten guards, his breath coming in jagged, agonizing hitches.
His heart felt like a trapped bird slamming against the bars of his ribs, the "Fourteen-Hour Void" of his previous training finally demanding its pound of flesh.
"Get him!" the lead guard shouted, swinging a heavy, electrified baton.
Sherlock dropped into a low crouch, his fingers grazing the ground.
"Paper Art: Thousand Needle Rain"
Hundreds of tiny paper shards erupted from his sleeves, pinning the guards' boots to the asphalt. It wasn't enough to stop them, but it created the 0.8 seconds of hesitation he needed. He blurred through their ranks, a whirlwind of tan and white, using the momentum of his fall to strike at their pressure points with his open palms.
Gang Orca lunged. He didn't use a sonic wave this time; he used his raw, terrestrial power. He struck at Sherlock with a palm-thrust that carried the weight of a breaching whale.
Sherlock crossed his arms, manifesting every scrap of paper left in his reserves into a small, dense "Shield-Fold" over his forearms.
The impact was cataclysmic.
Sherlock was sent skidding across the plaza, his boots carving deep furrows into the concrete. He didn't fall. He didn't faint. He slammed his heel into a crack in the pavement, his body leaning back at an impossible angle as he forced himself to stay upright.
"I... am not... subtracted," Sherlock gritted out through clenched teeth. A single drop of blood fell from his lip, staining the white paper on his arms.
his eyes finding the little girl in the medical ward—the one holding his paper lily. She was watching him, her eyes wide with hope.
If he used the blood paper, he would become the very thing he hated: a hero who sacrificed his humanity for a result. He would be just like the tragic "Pulp Princess" he had spent his life trying to forget.
He pulled his hand away from the zipper.
"I will win as a mathematician," Sherlock roared, his voice finally finding its full, resonant power. "Not as a martyr!"
The ground suddenly turned to ice. A massive wall of frost erupted between Sherlock and Gang Orca, followed immediately by a streak of green lightning that blurred past Sherlock's side.
"Nice work holding the line, Sherlock!" Midoriya yelled, his One For All: Full Cowl sparks illuminating the smoke. "We've finished the northern sector! We're here to take over the defense!"
Todoroki slid to a halt beside Sherlock, his left side already beginning to steam as he prepared to counter Gang Orca's heat-resistance. "You've done enough. Get back to the ward. We'll handle the heavy lifting."
Sherlock stood tall, refusing the support of Todoroki's offered hand. He wiped the blood from his lip with the back of his glove, his breathing slowly—painfully—starting to stabilize.
"The math of the encounter has shifted," Sherlock said, his voice regaining its cool, analytical timbre. "Gang Orca's resonance is high. Midoriya, strike from the 10 o'clock vector to disrupt his breath. Todoroki, use the ice to dampen the vibrations of the next sonic wave. I will provide the structural support."
"You're still fighting?" Midoriya asked, amazed.
"The Magician does not leave the site until the building is secure," Sherlock replied.
For the next five minutes, the central plaza became a masterclass in heroism. Midoriya and Todoroki provided the power, but Sherlock provided the Logic.
When Gang Orca unleashed a sonic blast, Sherlock manifested a series of "Paper Baffles"—curved, aerodynamic sheets that funneled the sound away from the medical ward and toward the empty ruins. When the elite guards tried to regroup, Sherlock used his last remaining Paper Insects to trip them or jam their equipment.
He didn't faint. He didn't falter. He stood as a silent, tan-clad sentinel amidst the chaos. He was a ghost in the machine, a boy who had looked into the abyss of his own physical limits and told it that it was statistically insignificant.
As the clock on the stadium walls ticked down to the final thirty seconds, Gang Orca stopped. He lowered his hands, a deep, resonant rumble of laughter escaping his chest.
"Impressive," the No. 10 Hero said, looking at the exhausted, battered students. "You didn't just protect the victims. You protected the idea of safety. Especially you, Paper Magician. You fought like a man who has nothing left to lose, yet everything to prove."
The siren wailed—a long, high-pitched note that signaled the end of the second round.
[EXAM CONCLUDED. ALL EXAMINEES RETURN TO THE CENTRAL HUB.]
Sherlock didn't collapse. He took a long, shaky breath, and slowly, methodically, he began to fold the last piece of paper in his hand. He didn't make a sword or a shield. He made a small, perfect Paper Plane.
He tossed it into the air, watching it glide over the medical ward, over the victims, and into the clearing smoke.
"The calculation... is complete," Sherlock whispered.
He turned toward Momo and the rest of Class 1-A. They were all looking at him—not as the cold, distant genius they had first met, but as a hero who had bled for them without hesitation.
Sherlock Sheets, the boy who once thought heroism was a waste of time, finally understood the math. It wasn't about the cost. It was about the value of what was saved.
He stood his ground, his eyes fixed on the horizon, waiting for the scores that would change his life forever.
One, the battle is over! Sherlock pushed past his limits without breaking.
