Chapter 2: The Vacuum Seal
The shrill ring of the midday chime was the greatest sound Yuta had heard all morning. A collective sigh washed over the classroom, instantly followed by the scraping of wooden chair legs against the linoleum floor. The stifling, tense atmosphere of the first day fractured, replaced by the chaotic energy of hungry teenagers eager for a break.
Yuta remained seated. He stretched his arms upward, feeling the satisfying pop of his shoulders releasing hours of accumulated stiffness. His stomach gave a quiet rumble. While most of his classmates hurried toward the cafeteria or the sunny courtyard, he preferred the relative quiet of the half-empty room. He reached into his bag and retrieved a square container wrapped in plain dark cloth.
Unknotting the fabric, he revealed a simple meal: white rice, grilled chicken, and a neatly folded omelet. Pure, functional fuel.
"Come on, yield!" a frustrated groan drifted from the next row.
Yuta paused with his chopsticks halfway to his mouth. He glanced over. Sora, the girl with the oversized purple scarf, was locked in a fierce battle with a sleek, metallic soup flask. She had it clamped between her knees, both hands gripping the lid, her face turning a mild shade of pink from exertion.
The metal was perfectly smooth, and the vacuum seal was doing its job entirely too well. Her hands kept squeaking against the polished surface, slipping right off the cap every time she applied maximum force. She let out a heavy breath, her bangs fluttering upward.
Yuta observed the physics of her dilemma. The container was cylindrical; there were no edges to provide leverage. Every time she twisted the top, the bottom rotated with it, canceling out her effort. He considered ignoring it. The food in front of him was getting cold. But the continuous, high-pitched squeak of skin sliding on metal was beginning to grind against his nerves.
He set his chopsticks down softly. Pushing his chair back, he closed the short distance between their desks.
"Place it flat on the table," he said, his voice quiet enough not to startle her, but clear enough to cut through her frustration.
Sora looked up, a bead of sweat forming on her temple. She blinked, then complied without arguing, setting the stubborn flask upright on the wooden surface.
Yuta didn't offer a reassuring smile. He simply pressed his open palm firmly against the bottom edge of the metal cylinder. He focused his mind, activating his Quirk. The familiar, dull ache bloomed in his knuckles. In a fraction of a second, the density of the flask's base increased exponentially. The object became impossibly heavy, sinking a microscopic fraction of a millimeter into the desk's varnish, anchoring it with the weight of a small boulder.
"Twist," he instructed.
Sora grabbed the lid. With the base completely immobilized by Yuta's invisible weight, all her rotational force was finally directed exactly where it needed to go.
Pop. Hiss. The seal broke instantly, releasing a puff of savory, steam-filled air that smelled strongly of miso and green onions.
"Ha! Victory!" Sora cheered softly, a wide, genuine grin spreading across her face. "Thanks, Yuta. I was about to throw it out the window."
"I knew it!"
The sudden, loud exclamation made them both jump. Ren appeared seemingly out of nowhere, popping up from the side aisle. He had a half-eaten egg sandwich clutched in one hand, and his yellow sweater was now tied casually around his waist.
"I saw the desk creak!" Ren continued, his eyes wide with uncontainable excitement, leaning far too close. "You did the heavy thing again! That's your Quirk, right? You make stuff weigh a ton!"
"Please lower your volume," a composed voice drifted over from the adjacent row.
Hana was sitting perfectly upright at her desk, holding a pair of wooden chopsticks with practiced elegance. Her own lunch was arranged with military precision. She hadn't even looked up from her meal, but her tone carried a gentle, yet undeniable, authority. "A classroom is a shared environment. We are trying to enjoy our midday recess."
Ren sheepishly rubbed the back of his neck but didn't actually leave. Instead, he pulled an empty chair from a neighboring desk, flipped it around, and straddled it, resting his arms on the backrest. "Sorry, sorry. But it's really cool! It's so subtle. Villains wouldn't even notice until they tried to pick something up and broke their backs."
Yuta released the density effect, shaking his hand slightly to shake off the lingering phantom ache. "It just alters mass," he corrected calmly, turning to walk back to his own untouched food.
He intended to eat in silence. However, by the time he sat down, the spatial dynamic of the room had shifted. Sora had unceremoniously dragged her desk backward until it bumped lightly against his. Ren was still planted in the aisle between them, chewing happily on his sandwich.
"So, altering mass," Hana suddenly spoke again. She had paused her eating, her analytical gaze locking onto Yuta. "If you applied that principle to a blunt weapon, the kinetic impact would multiply drastically upon swinging, without changing the aerodynamic size of the object. It is highly efficient."
Yuta paused, a piece of chicken hovering near his mouth. He hadn't expected the quiet, disciplined girl to immediately dissect the combat applications of his power. "Theoretically, yes," he admitted, finally taking the bite. "But maintaining the state drains my stamina rapidly. And physical contact is required."
"Still awesome," Sora mumbled through a mouthful of soup. "My trait is just momentum. If I'm running, I can turn sharp corners without losing speed. Great for skateboarding. Terrible for fighting giant monsters."
The conversation flowed onward, messy and completely unplanned. They were just ordinary kids dissecting their flaws and sharing theories over rice and soup. No grand declarations of teamwork were made. No dramatic oaths were sworn to protect the innocent.
Yuta ate slowly, listening to Ren ramble about a recent incident involving a popular pro hero, while Sora occasionally interjected to correct his exaggerated facts. Hana merely nodded silently whenever Sora made a valid point.
The journey to the prestigious halls of U.A. High was still countless miles away, obscured by years of necessary growth. But as Yuta listened to the overlapping, entirely human chatter surrounding his desk, the long road ahead felt infinitesimally less isolating.
