Chapter 1: Chasing the Wind
The late sun bled orange across the UA training grounds, stretching the shadows of the obstacle course into long, jagged teeth. Kaori Kono floated ten feet above the churned earth, suspended on a current of air that ruffled her long, snow-white hair. Below her, Katsuki Bakugo snarled, sweat tracing paths through the grime on his forehead. Another explosion ripped from his palms, a concussive BOOM that sent tremors through the ground and kicked up a choking cloud of dust and grit.
It barely ruffled Kaori’s makeshift skirt. She laughed, the sound bright and clear, cutting through the fading echoes of the blast. “You’ll have to try harder than that to catch me, Bakugo!” she called down, her grin wide and effortless. Sunlight caught the sweat beading on her exposed midriff above her training shorts, making her skin gleam like polished bronze. She shifted her weight, the air beneath her feet swirling lazily, keeping her aloft with deceptive ease.
“Shut up, Windbag!” Bakugo roared, launching himself upwards with a series of smaller, rapid detonations. His trajectory was fierce, direct, a human missile aimed straight at her hovering form. His red eyes burned with pure, unadulterated frustration. “Quit screwing around!”
Kaori’s smile didn’t waver, but her green eyes narrowed slightly, focusing. She wasn’t just riding the wind; she was feeling it. The subtle shifts in pressure, the eddies swirling around Bakugo’s explosive ascent. As he rocketed towards her, she tilted sideways. Not fast, but precisely. A gust, summoned seemingly from nowhere, caught her mid-air pirouette and flung her sideways just as Bakugo’s grasping hand sliced through the space she’d occupied a heartbeat before.
He roared again, twisting mid-air, another explosion blasting him sideways to pursue. Dust devils swirled in his wake. “Stand still and fight!”
“Where’s the fun in that?” Kaori countered, darting higher on a thermal updraft she coaxed from the warm concrete below. She weaved between imaginary obstacles, her movements fluid, almost playful. To Bakugo, it looked infuriatingly effortless. Like she wasn’t even trying. Like she was mocking him.
He hated that. Hated the way her stupid white hair always looked perfectly windswept. Hated the constant, grating cheerfulness. Hated how everyone, everyone, seemed to adore her sunny disposition, even teachers who usually had zero tolerance for nonsense. Especially hated how her Quirk seemed to defy physics just to annoy him.
He pushed harder. Faster. Explosions ripped the air, each blast a punctuation mark to his fury. He chased her erratic path across the training field – over mock buildings, around towering concrete pillars, skimming the tops of reinforced walls. Kaori danced on the wind, laughing, taunting, always just out of reach. Her control was impressive, Bakugo begrudgingly admitted to himself, even as he vowed to blast her out of the sky. It wasn't just power; it was finesse, an instinctive understanding of the air itself.
“Getting tired, Dynamight?” Kaori teased, executing a tight corkscrew dive that avoided a searing blast meant to clip her heels. She landed lightly on a high wall, crouching like a cat. Her breathing was quickened, a faint flush on her cheeks the only sign of exertion. She flashed him that dazzling smile. “Need a breather?”
“I’ll breathe when you’re eating dirt!” Bakugo snarled, landing with a heavy thud on the wall opposite her, cracking the reinforced concrete under his boots. He didn’t pause. He lunged, not bothering with explosions this time, aiming to tackle her directly, to pin that infuriating agility.
Kaori’s eyes widened fractionally. Too close. She pushed off the wall, but Bakugo was faster, stronger. His hand clamped around her ankle just as her wind caught her. He yanked, hard, pulling her off balance. Her startled yelp was swallowed by the rush of air as she tumbled downwards, Bakugo falling with her, his grip iron-tight.
They hit the ground in a tangle of limbs, rolling across the rough turf. Bakugo ended up on top, pinning her wrists beside her head with one hand, the other crackling ominously near her face. Dust coated them both. His chest heaved against hers, his breath hot and ragged in her ear.
“Gotcha,” he growled, triumph lacing the fury in his voice. His red eyes bored into hers, expecting fear, surrender, anything but that damnable cheer.
Kaori blinked up at him. Her hair was mussed, grass stains smudged her cheek, but her expression was… curious. Assessing. Then, slowly, that familiar, brilliant smile crept back onto her lips. It wasn’t mocking now. It was… warm. Genuine. “Good one, Bakugo!” she said, her voice breathless but bright. “You’re really fast!”
The sheer, unexpected sincerity of it threw him. The compliment, delivered while pinned under him, disarmed his rage like a bucket of cold water. He stared, bewildered. Who was this girl? How could anyone be so relentlessly… happy? Especially after being tackled by him? It felt alien. Wrong. Like looking at a sunbeam trapped in a jar.
His grip on her wrists loosened slightly. He saw it then – a flicker. So fast he almost missed it. A shadow passing behind her vibrant green eyes. A micro-expression of something… else. Not fear. Something older. Deeper. It vanished instantly, replaced by her usual sunny regard, but the glimpse was jarring. Like catching a glimpse of cracked porcelain beneath flawless paint.
“Get off,” he muttered, the heat gone from his voice, replaced by gruff confusion. He pushed himself up, releasing her abruptly. He stood, brushing dirt off his pants, avoiding her gaze.
Kaori bounced to her feet with surprising energy, dusting herself off. “That was fun!” she declared, stretching her arms overhead. The movement pulled her tank top taut, revealing a thin, silvery line, almost invisible against her dusky gold skin, running diagonally across her ribs just below her sports bra. It was old, faded, but starkly out of place on her vibrant frame. Bakugo’s eyes snagged on it for a split second before flicking away.
Fun? Getting slammed into the dirt was fun? He grunted, turning towards the locker room building, the setting sun casting long, distorted shadows ahead of him. “Whatever. Training’s over.” He needed space. Needed to process the weird disconnect between her relentless sunshine and that fleeting darkness he’d glimpsed. And that scar… where did that come from?
Kaori fell into step beside him, humming softly. The breeze, calmer now, still played with strands of her white hair. She seemed utterly unfazed by the brutal takedown, her energy seemingly boundless. “Race you to the lockers?” she suggested, her eyes sparkling with challenge.
“Tch. As if.” Bakugo shoved his hands deeper into his pockets, scowling at the lengthening shadows. He walked faster, leaving her slightly behind. Her cheerful hum followed him, a counterpoint to the uneasy churn in his gut. He’d won the spar. So why did it feel like he’d lost something? Why did that glimpse behind her smile unsettle him more than any explosion?
The locker rooms were quiet, most other students long gone. Bakugo showered quickly, the hot water failing to wash away the strange residue of the encounter. He dressed mechanically, his thoughts circling back to Kaori’s eyes in that moment of impact. That wasn't the look of someone who’d never known hardship. It was the look of someone who knew it intimately and had built a fortress of cheer to keep it out.
He slammed his locker shut, the metallic clang echoing in the tiled room. Annoying. She was just annoying. He pushed the thoughts aside, striding out into the cool evening air of the nearly empty parking lot. The city lights were starting to wink on in the distance.
He spotted her instantly. Kaori stood near the edge of the lot, bathed in the harsh, unforgiving glare of a sodium-vapor light. She wasn't moving towards the dorms or the main gate. She was facing the high chain-link fence bordering a darker, overgrown service road. Her posture was different. Still. Tense. The effortless breeze that usually surrounded her was gone. Her hair hung limp.
And she wasn't alone.
Two figures, silhouetted against the deeper gloom beyond the fence, stood uncomfortably close. Their posture wasn't friendly. One leaned forward, invading her space, his hand gesturing sharply. Kaori took a small step back, her head bowed slightly. Bakugo couldn't see her face, but the vibrant energy, the effortless joy, was utterly absent. She looked… small. Cornered.
Bakugo stopped dead. Every instinct honed by years of hero training screamed wrong. The cheerful, infuriatingly resilient girl who laughed off his explosions was gone. In her place stood someone radiating a quiet, chilling vulnerability. The shadow he’d glimpsed earlier wasn't just a memory; it was a tangible presence, swallowing the light around her.
His hands clenched into fists at his sides. The uneasy churn in his gut solidified into cold, hard anger. Without conscious thought, his feet started moving, carrying him towards the harsh pool of light and the unsettling scene unfolding within it. His scowl deepened, not with annoyance this time, but with a fierce, protective instinct he didn't fully understand. The laughter on the training field felt like a lifetime ago.
The laughter on the training field felt like a lifetime ago. Bakugo’s boots crunched on loose gravel as he stalked across the parking lot, his focus narrowed to the harsh pool of light and the unsettling tableau within it. The two figures loomed over Kaori, their silhouettes sharp and aggressive against the dark tangle of the service road beyond the fence. One leaned in, too close, his hand gesturing sharply, a finger stabbing the air near her face. Kaori had taken another step back, her shoulders hunched slightly, her head bowed. The usual breeze that animated her hair was utterly still; it hung heavy and limp around her face, hiding her expression. She looked fragile. Cornered. Like prey.
Bakugo’s jaw tightened. The cold anger that had replaced the uneasy churn in his gut flared hotter. He didn’t break stride, didn’t call out. His presence was a heavy, advancing pressure.
One of the figures glanced sideways, a fractional turn of the head. Then the other followed suit. They froze for a split second, taking in Bakugo’s unmistakable silhouette – the spiky blonde hair, the rigid posture radiating menace even in the gloom. Recognition, or perhaps just the raw, intimidating aura of an approaching Pro Hero trainee, flashed between them. Without a word, without even looking back at Kaori, they melted backwards, deeper into the shadows beyond the fence. One gave a final, dismissive jerk of his chin before both vanished into the darkness as abruptly as they’d appeared.
The suddenness of their departure broke the oppressive stillness. Kaori flinched, her head snapping up in surprise. She blinked, scanning the empty darkness where the men had been, confusion etching lines onto her forehead. Then she turned, following the trajectory of their vanished stares.
Her eyes landed on Bakugo, barely ten paces away now.
It was instantaneous. Like flipping a switch. The tension bled out of her frame. Her shoulders squared. Her chin lifted. And that effortless, blinding smile bloomed across her face, chasing away every trace of vulnerability as if it had never existed.
“Bakugo!” she chirped, her voice regaining its familiar, buoyant lilt. She took a few quick, light steps towards him, her white hair catching a stray breeze that seemed to materialize just for her. “Fancy meeting you here! Heading back to the dorms?”
Bakugo stopped dead. He stared at her, his red eyes wide, the anger momentarily replaced by sheer, disorienting disbelief. The shift was jarring. Too fast. Too perfect. It wasn't just cheerful; it felt manufactured. A performance cranked to eleven. The girl who’d looked seconds away from crumbling under the pressure of those creeps was now beaming at him like they’d just bumped into each other at a sunny cafe.
He couldn’t reconcile it. The image of her small, tense form under the harsh light warred violently with this sudden, radiant burst of energy. His gaze flickered down, almost involuntarily, to where her fitted tank top rode up slightly as she moved. The thin, silvery scar below her ribs caught the sodium light, a stark, silent contradiction to the flawless happiness she projected.
“Who the hell were those guys?” he demanded, his voice rougher than he intended. He didn’t move closer. Didn’t relax.
Kaori waved a dismissive hand, the motion almost too airy. “Oh, them? Just asking for directions! Totally lost, poor things. This area can be confusing at night, you know?” She laughed, a bright, crystalline sound that felt brittle against the lingering tension. “Anyway! Race you? My legs feel like jelly after that awesome spar! You really nailed that takedown!”
She bounced lightly on the balls of her feet, radiating eagerness, but her eyes… Bakugo stared hard. They were still bright green, still smiling, but the warmth didn't reach their depths. It was like looking at sunlight reflecting off ice. The shadow he’d glimpsed earlier was back, not fleeting this time, but lurking just beneath the surface of her performance. And he saw something else: a faint tremor in the hand she’d waved, quickly tucked behind her back.
‘Awesome spar’? ‘Nailed that takedown’? His mind screamed the contradictions. She’d been pinned, slammed hard, seconds away from having his palm explode in her face. And she was calling it awesome? While moments later, she looked like the world was ending because of two random guys asking for directions?
“Tch. Directions,” Bakugo muttered, the disbelief thick in his voice. He didn’t buy it. Not for a second. The men hadn’t looked lost. They’d looked predatory. Kaori hadn’t looked helpful; she’d looked terrified. And this sudden, hyperactive cheer felt like a desperate shield.
He didn’t push. Not yet. The raw vulnerability he’d witnessed was too stark, too intimate. Prying felt… wrong. Like kicking someone when they were already down, even if they were pretending not to be.
He shoved his hands deeper into his pockets, the familiar scowl settling back over his features, though it lacked its usual heat. “Whatever. Let’s go,” he grunted, turning and starting towards the dorm path. He walked slower than usual, his usual explosive stride muted.
Kaori fell into step beside him, instantly matching his pace. The breeze picked up again, playfully tugging strands of her hair. “So,” she started, her voice artificially bright, “what’s for dinner? I’m starving! Bet I could eat a whole cow!” She chattered on, filling the space between them with inconsequential noise – speculations about the cafeteria menu, a funny thing that happened in Support Class, a question about tomorrow’s training schedule.
Bakugo barely registered the words. He kept his gaze fixed ahead, but his mind was churning. The image of her under that light – small, tense, utterly unlike the Kaori Kono everyone knew – replayed over and over. The forced cheerfulness grating on his nerves. That scar, a pale whisper against her skin, a history he couldn’t begin to guess.
He stole another sideways glance. She was looking straight ahead, still talking, that dazzling smile firmly in place. But in the dimming twilight, away from the harsh sodium glare, he saw the faint, tell-tale tracks of moisture drying on her cheeks, hastily wiped away but not completely gone.
His scowl deepened into something darker, more troubled. The question wasn't what had just happened. It was why? Why the act? Why the fear? And why did seeing her force that smile, seeing the ghost of tears she tried to hide, make something unfamiliar and uncomfortable twist sharply in his chest?
He walked beside the embodiment of sunshine, and for the first time, he felt chilled by the shadows clinging stubbornly to her light.
