Chapter 5: The Friction of Beginnings
The morning sun filtered through the grime of the Grey District, casting long, jagged shadows across the warehouse floor. Kaito Enma stood before a cracked mirror, the silver-and-grey fabric of the U.A. High School uniform feeling like a foreign skin. It was stiff, expensive, and smelled of industrial detergent—a sharp contrast to the salt-and-rust scent of the life he had known under the bridge.
On the scarred wooden table behind him sat a small, black debit card embossed with the gold U.A. crest. Beside it was a formal document from the Ministry of Education.
Because Juro Ishida had successfully filed the adoption papers before his death, Kaito was officially registered as a "Hero-Track Ward." The card was his lifeline—a monthly government allowance designed to cover the astronomical caloric needs of a student with a high-metabolic quirk.
It wasn't a fortune, but for a boy who had once fought over discarded protein bars, it was a mountain of gold. It was the price of his silence and his potential, a quiet agreement that the state would feed the engine as long as the engine served the state.
Kaito picked up the card, the plastic cold against his obsidian-etched palm. He slid it into his wallet, took a final, steadying breath, and let his internal temperature drop to a calm, defensive low.
"I'm going, Juro," he whispered. The warehouse didn't answer.
The Journey to the Tower
The commute to Musutafu was a descent into a sensory hell. The train was a pressurized tube of human heat and erratic rhythms. Kaito stood in the corner of the carriage, his hood pulled low. His Sonar was impossible to turn off; it mapped the world in pulses of vibration.
He could feel the hydraulic hiss of the train's brakes, the rhythmic thud-thud of the wheels on the tracks, and the cacophony of a hundred different heartbeats.
To a boy who had lived in the hollow silence of a warehouse, the city was a roar. Every person was a thermal bloom, a walking furnace of energy. He saw the "Golden Boys" in their pristine middle school uniforms, their heartbeats light and carefree. He felt like a predator among sheep, his own pulse a low, controlled thrum that signaled a different kind of life.
When he reached the gates of U.A., the sheer scale of the architecture hit him. The glass towers reached for the sky like shards of ice. He walked through the oversized hallways, his boots echoing against the polished linoleum.
Class 1-A: The Shadow in the Back
Kaito pushed open the door to Class 1-A. It was massive—built for giants—but the room inside was already a storm of personalities.
He didn't look at the others. He didn't want to see the hope or the arrogance in their eyes.
He moved to the very last seat in the row closest to the window. It was the perfect vantage point. To his left, the glass provided a view of the training grounds; to his right, he could map every student in the room.
Directly in front of him sat a girl who seemed to exist in a different frequency than the rest of the class. Her hair wasn't hair at all, but a cascading, thick waterfall of thorny green vines. Ibara Shiozaki.
As Kaito sat down, several of her vines slid off her shoulder and rested across the edge of his desk. They were vibrant, smelling faintly of damp earth and morning dew. He stared at the thorns, his Sonar picking up the slow, steady flow of nutrients through the plant tissue. It was the calmest heartbeat in the room.
Ibara turned slightly, her expression one of soft, genuine concern. "Oh, I crave your forgiveness," she whispered, her voice like wind through leaves. "My tresses have a mind of their own when the morning sun is so bright. I hope they do not intrude upon your space."
Kaito looked from the vines to her eyes. He didn't smile. "It's fine," he said, his voice a low rasp. "They don't make much noise."
Ibara tilted her head, a small, curious frown touching her lips. "Noise? You are a strange one, Kaito Enma. But may the light find you today."
She turned back, and Kaito focused on the front of the room. The silence didn't last.
A boy with glasses—Tenya Iida—was already shouting at a spiky-haired boy named Bakugo for disrespecting the school furniture.
"Don't put your feet on the desk!" Iida barked, chopping the air with his hands.
"Hah? Get lost, Four-Eyes," Bakugo growled.
The door opened, and a green-haired boy—Izuku Midoriya—stumbled in, looking like he was walking to his execution. He was followed by a girl with a permanent blush, Ochaco Uraraka.
"If you're here to make friends, you can pack your bags."
A yellow sleeping bag lay on the floor. From within it, a man with tired, bloodshot eyes crawled out. Shota Aizawa. The room went cold. Kaito's Sonar spiked—the man's heartbeat was almost undetectable, a sign of a true professional.
"It's a bit sudden, but put these on," Aizawa said, tossing a gym uniform onto the front desk. "Head to the P.E. grounds."
The class stood on the dirt field, the blue-and-white gym uniforms feeling light against the skin. Aizawa stood at the center, his scarf hanging loosely around his neck.
"The Principal has requested a briefing on your abilities," Aizawa said. "Because this class has been reconstructed with high-tier students, you will state your name and the mechanical nature of your quirk. No fluff. Just the facts."
The Introduction of Quirks
Izuku Midoriya stepped forward, his voice cracking. "I-I'm Izuku Midoriya! My quirk is a Super-Power! It allows for a massive burst of physical strength, but I... I have a high recoil."
Tenya Iida followed, gesturing to his legs. "Tenya Iida! Quirk: Engine! I have organic engines in my calves! They run on orange juice!"
Ochaco Uraraka smiled. "I'm Ochaco! My quirk is Zero Gravity. I can make things float, but I get nauseous!"
Next came the powerhouses. Eijiro Kirishima hardened his arm until it looked like jagged stone. "Eijiro Kirishima! Quirk: Hardening! I'm the ultimate spear and shield!"
Beside him, a boy with silver hair did the same, his skin turning a metallic grey. "I'm Tetsutetsu Tetsutetsu! My quirk is Steel! My skin becomes a metallic alloy! It's basically the same as yours, man!"
"No way!" Kirishima grinned. "That's so manly! We're like twins!"
Momo Yaoyorozu, a girl with a sophisticated air, explained her Creation quirk—converting lipids into physical matter.
The Nitroglycerin Catalyst Bakugo didn't wait to be called. He stepped forward with a slouch that radiated pure, unadulterated arrogance. He held up his palms, which were already shimmering with a thin layer of translucent liquid.
Ibara stepped forward next, her hands clasped in front of her. She looked more like she was in a cathedral than a training ground.
She bowed her head slightly, her green, vine-like tresses swaying in the breeze.
"I am Ibara Shiozaki," she began, her voice soft but clear. "My Quirk is Vines. These tresses upon my head are not hair, but complex botanical structures capable of rapid elongation and manipulation. They possess a high tensile strength and are rooted directly into my scalp, drawing nutrients from my own internal hydration and sunlight."
One of her vines reached out, delicately picking up a small stone from the dirt and crushing it into powder. "I can use them to bind those who have lost their way or as a shield against the storms of the world.
However, if they are severed, I feel the sting as if they were my own limbs, and they require water and rest to regrow. I seek only to use this gift for the glory of the light."
"She's like a forest goddess," Uraraka said, tilting her head. "But those thorns look like they could tear through metal if she wanted them to."
Then, the bi-colored boy, Shoto Todoroki, spoke. "Shoto Todoroki. Half-Cold Half-Hot. I generate ice from my right and fire from my left."
The class went silent. It was a perfect quirk—the pinnacle of elemental balance.
Finally, Aizawa looked at the back of the line. "Enma."
Kaito stepped forward. He felt the weight of their eyes—the curiosity of Midoriya, the arrogance of Bakugo, and the cold analysis of Todoroki.
"Kaito Enma," he said. "My quirk is Thermal Overclock."
"Mechanism?" Aizawa asked.
"I can manually manipulate the temperature of my blood and internal organs," Kaito said, his voice steady. "By increasing my Blood, I accelerate my Heart rate and nerve signal speed. It's a biological acceleration. Like a high-performance engine."
Denki Kaminari leaned over to Minoru Mineta. "So he's basically a living human steroid? He boils his own blood to move fast?"
"That sounds terrifying," Mineta whispered.
"Like extreme doping. Doesn't that hurt?"
"Only if I stop," Kaito muttered, though only Aizawa heard him.
The Logic of the Test
"Alright," Aizawa said, his eyes glowing with a faint, predatory light. "Now that we've finished the introductions, we're doing a Quirk Apprehension Test. Whoever ranks last in total points across all eight tests will be judged as having 'No Potential' and will be Expelled."
The excitement evaporated. A sharp, jagged fear took its place.
"Bakugo, you placed first in the entrance exam," Aizawa said. "What was your softball throw in junior high?"
"Sixty-seven meters," Bakugo barked,
stepping into the white circle.
"Try it with your quirk."
Bakugo wound his arm back, his internal temperature spiking as his nitroglycerin sweat primed.
"DIE!" he roared.
A massive blast erupted from his palm. The ball disappeared into the blue, propelled by a localized shockwave. Aizawa turned his tablet around:
705.2 meters.
"Seven hundred meters?!" the class shouted.
Aizawa's grin was toothy and terrifying. "Now you see the reality of U.A. This isn't a playground. It's a proving ground."
He looked at his roster, then locked eyes with the boy in the back. "Enma. You're up. Show me the limits of that doping quirk."
Kaito walked toward the circle. He could feel Ibara's vines twitching in his peripheral vision, sensing the heat rising from his skin. He picked up the ball. He didn't just need strength; he needed the Shatter-Point.
"Thermal Overclock: Six Percent."
A hiss of steam escaped his collar as his engine began to roar.
