Chapter 1: Sparring Shadows
The air in the warehouse tasted of rust and old rain. Water dripped a steady, broken rhythm from a hole in the corrugated iron roof, each drop exploding on the concrete floor like a tiny bomb. Nala moved through the shadows, a whisper of motion, her platinum curls a wild cascade in the gloom.
“Getting slow, Deku,” she taunted, her voice echoing.
Izuku stood his ground, his breathing even, the faint green crackle of One For All dancing over his knuckles. “Or you’re just getting predictable.”
She came at him in a blur, a feint low followed by a spinning kick aimed at his head. He blocked, the impact a sharp crack that reverberated through the vast space. He grabbed her ankle, but she used his grip as a pivot, her other leg scissoring around his neck. With a grunt, she leveraged all her compact strength and slammed him back against the damp wall.
A laugh, sharp and triumphant, escaped her. “That predictable?”
His eyes, wide and green, met hers. For a second, there was only the sound of their ragged breathing and the endless drip-drip-drip. Then a slow, dangerous smile spread across his face. “Yeah. It is.”
In one fluid, powerful motion, he broke her hold, his hands shifting from her leg to her waist. He spun, reversing their positions, and pinned her against the cold concrete where he’d just been. The air left her lungs in a rush. He leaned in, his mouth close to her ear. “You always lead with your right when you’re showing off.”
From the sidelines, a plume of frost crystallized in the air, followed by a gentle wave of heat that melted it away. Shoto stood with his arms crossed, his heterochromatic eyes missing nothing. “He’s right. You did.”
Nala struggled, but Izuku’s hold was like iron. “This isn’t a team meeting, pretty boy,” she shot back at Shoto, her voice strained.
“Isn’t it?” Shoto replied, his tone flat. He uncrossed his arms and walked closer, the temperature around him fluctuating slightly. “We’re all here.”
The dynamic shifted. The competitive energy bled into something else, something thicker and more charged. Izuku’s grip on her wrists loosened, becoming less of a restraint and more of a caress. His thumb stroked the inside of her pulse point, feeling the frantic beat there.
“Got you,” he murmured, his voice low and rough, just for her.
Nala’s defiant posture softened. The ferocious hero-in-training facade crumbled, leaving just a girl, breathless and pinned. “Yeah,” she breathed out, the fight draining from her. “You got me.”
Shoto was there then, his cool hand coming to rest on the back of her neck, a stark contrast to the heat blooming where Izuku held her. “He’s not the only one.”
The warehouse, with its dripping sadness and decaying silence, ceased to exist. There was only the three of them, a tangled constellation of shared breaths and racing hearts. Izuku dipped his head, his lips finding the column of her throat, and Nala’s head fell back against the wall with a soft thud. Shoto’s fingers tangled in her wild hair, tilting her face towards his.
This was the truth they never showed in class. The competition, the sparring, the relentless drive to be the best—it was all just a prelude. A complicated, desperate form of foreplay.
A sharp crack split the air, followed by the screech of protesting metal.
A section of the warehouse’s second-floor railing glowed orange, then white-hot, before melting away. Katsuki Bakugo dropped through the new hole, landing in a crouch that sent a cloud of dust billowing out around him. He straightened up, his spiky hair silhouetted against the storm-grey sky visible through the broken roof.
“Would you three quit the fucking dramatic soap opera and move?” he snarled, his red eyes sweeping over their entangled forms with familiar impatience. “The real fight’s starting. Some idiot villains just tried to knock over a bank downtown. They’re heading for the canals.”
The spell shattered. In an instant, Nala was pushing away from the wall, Izuku was cracking his neck, and Shoto was letting a shard of ice form in his palm.
Katsuki’s gaze lingered on Nala for a half-second longer, a silent, possessive message passing between them before he turned toward the gaping warehouse door. “Stop wasting time. Let’s go.”
The rain had turned into a fine, persistent mist that clung to their costumes as they burst from the warehouse. The city spread out before them, a grid of glittering lights and wet asphalt.
“Left!” Izuku’s voice cut through the din of the city, his body already moving. “They’re using the lower canals to avoid aerial patrols!”
Katsuki didn’t bother with a reply. He just launched himself forward with a series of concussive blasts, a human projectile tearing through the rain. Nala was a streak of fire at his side, her feet barely touching the puddles forming on the pavement.
They hit the canal system—a labyrinth of concrete channels and murky, rushing water. The villains were there, three of them, perched on a bizarre, spider-like vehicle that skittered along the concrete wall.
“Flashy,” Shoto noted, his voice calm as he came to a halt beside them. A sheet of ice instantly shot across the canal, blocking the vehicle’s path.
The vehicle screeched, pivoting on too many legs. One of the villains, a hulking man with metal grafted to his knuckles, leaped off.
“UA brats! Just our luck!” he roared, charging.
Nala met him head-on. She didn’t try to match his strength. Instead, she flowed under his swing, a dancer avoiding a clumsy partner. Her hand, wreathed in blue-hot flame, tapped his chest plate. Not a blast, just a touch. The metal glowed cherry red for a second before he yelled, stumbling back from the intense, localized heat.
“Lucky us,” she said, her voice a low purr.
Izuku was a green blur, ricocheting off the walls, using the geometry of the space to his advantage. He disarmed a villain with a whip-like quirk with a precise, shin-breaking kick. The man crumpled with a cry.
The third villain, a woman, tried to blindside Shoto with a spray of acidic goo. He didn’t even turn. A wall of ice erupted to intercept it, sizzling as the acid met its match. With his other hand, he sent a controlled burst of fire that singed the woman’s sleeves, forcing her to retreat straight into Katsuki’s waiting grip.
Katsuki slammed her into the ground, a knee in her back. “Don’t move,” he growled, the threat in his voice more effective than any restraint.
It was over in less than a minute. The fight was clean, efficient, a brutal sort of poetry only they could write together.
As the police lights began to strobe blue and red against the wet concrete, the four of them stood back, a single unit catching their breath. The professional mask was back in place.
“Your form was sloppy on that initial approach, Bakugo,” Izuku said, wiping rainwater from his face. “You left your right side open for a full second.”
“Shut it, nerd. I was baiting him. Unlike some people, I can take a hit,” Katsuki shot back, though there was no real heat in it.
Shoto looked at Nala. “You hesitated before you engaged the knuckle-duster guy. Why?”
Nala watched the police cuff the villains. “His plating was a cheap alloy. I didn’t want to melt through it and actually cook him. Bad for PR.”
A faint, almost imperceptible smile touched Shoto’s lips. “Practical.”
They made their way back to the UA dorms in a comfortable silence, the adrenaline fading, leaving behind a familiar, buzzing exhaustion. The common room was empty, the only light coming from the city through the large windows.
The moment the dorm door clicked shut behind them, the tension of the public world evaporated. It was like shedding a second skin.
Nala slumped onto the large couch, pulling the band from her hair and letting the platinum curls tumble free. “I’m starving.”
Izuku was already in the kitchen, pulling out containers of leftover rice and vegetables. “I’ll make something.”
Katsuki dropped into an armchair, propping his feet on the coffee table. “Make it edible this time, Deku. Not that salty crap you made last week.”
“You ate three bowls of it,” Izuku retorted without looking up.
“I was hungry, not impressed.”
Shoto sat on the floor, leaning back against the couch near Nala’s legs. He reached up and without a word, started gently kneading the tension from her calf. She let out a soft sigh, her eyes fluttering closed.
This was the other side of it. The quiet after the storm. The competition and the violence were real, but this was too. This unspoken agreement to tend to each other’s bruises, both seen and unseen.
Izuku brought over bowls of steaming fried rice. They ate in silence for a few minutes, the only sound the clink of chopsticks and the distant hum of the city.
“You did good today,” Izuku said softly, his eyes on Nala. “All of you.”
Katsuki grunted, shoveling another bite into his mouth. “We won. That’s the baseline.”
“It’s more than that,” Shoto said, his voice quiet. He’d finished with her calf and now just let his hand rest on her ankle, his thumb making absent circles. “We function. As a unit.”
Nala opened her eyes and looked at each of them—Izuku’s focused kindness, Shoto’s quiet intensity, Katsuki’s raw, unwavering fire. Her pillars. Her secret.
She set her empty bowl aside and slid off the couch, joining Shoto on the floor. She leaned her head against his shoulder. After a moment, Izuku came over and sat on her other side, his arm brushing hers. Even Katsuki, after a dramatic sigh, slid from the chair to the floor, completing their loose circle.
No one spoke. There was no need. The press of a shoulder, the brush of a hand, the shared warmth—it was all a language they understood perfectly. Outside, the city kept moving, unaware of the four heroes-in-training, tangled together on a dorm room floor, finding their strength in the quiet spaces between each other.
The quiet was a living thing, warm and heavy in the dim room. It was Katsuki who broke it, his voice a low rumble that seemed to vibrate through the floorboards. "My shoulder's fucked."
The statement hung there, simple and factual. It was as close to a request for help as he would ever get.
Nala untangled herself from Shoto and Izuku, her movements fluid. She crawled over to him on her knees. "Let me see."
He shrugged out of one side of his jacket, his movements stiff. The black fabric of his shirt beneath was damp with sweat. Nala’s fingers, surprisingly cool, pressed into the knotted muscle of his deltoid. He hissed through his teeth, a sharp intake of breath.
"Idiot," she murmured, her touch firming, working at the tension with a practiced knowledge of his body. "You overcompensated on that last blast. I saw you favor it."
"Did not," he grunted, but he leaned into her hands, his head bowing.
Izuku watched them, his analytical mind quietly cataloging the minute flicker of pain in Katsuki’s eyes, the way Nala’s brow furrowed in concentration. This was part of their rhythm, too. The assessment after the fight, the patching up. Shoto reached for the first-aid kit they kept under the coffee table without being asked, his movements silent and efficient.
"Here," Shoto said, holding out a tube of analgesic gel.
Nala took it, her fingers brushing his. The simple contact sent a current through the quiet space. She squeezed the cool gel onto her palms and went back to work on Katsuki’s shoulder, her small hands moving with a strength that belied her size.
Katsuki’s jaw was clenched, his eyes squeezed shut. "Harder."
"You'll bruise," she warned, but she increased the pressure, her thumbs digging deep into the ropey muscle.
"Don't care."
A few minutes passed, filled only with the sound of their breathing and the slick slide of gel on skin. The rigid line of Katsuki’s back began to soften, incrementally. The fight finally, truly, left his body.
When she was done, he rolled his shoulder experimentally, a slow, testing rotation. A grunt of approval. That was all the thanks she would get, and it was enough.
He didn't move away. Instead, his good arm came up, his hand wrapping around her wrist where she still rested it on his shoulder. His thumb stroked the delicate skin over her pulse point, a mirror of Izuku’s gesture in the warehouse. His red eyes, when they opened and found hers, were stripped of their usual explosive anger. They were just intense, focused solely on her.
The air tightened.
Izuku felt it, a shift in the atmospheric pressure of the room. He looked at Shoto, who met his gaze with a quiet, knowing stillness. There were no words. There never were.
Katsuki tugged gently on Nala’s wrist, pulling her from her knees until she was settled in the space between his legs, her back against his chest. He wrapped both arms around her, his chin resting on the crown of her wild hair. She sank into the contact, a soft sigh escaping her.
It was an invitation.
Izuku moved first, shifting closer until he was facing them. He reached out, not for Nala, but for Katsuki, his fingers gently tracing the line of his jaw. Katsuki’s eyes slid shut again, but this time it wasn't from pain. It was a surrender.
Then Izuku leaned in, his lips finding Nala’s. It wasn't a gentle kiss. It was hungry, full of the night's pent-up energy, a reclaiming. She met his intensity, her hand coming up to curl into the fabric of his shirt.
When they broke apart, breathing heavily, Shoto was there. He cupped Nala’s face, turning her towards him. His kiss was different—slow, deliberate, a counterpoint to Izuku’s fire. It was a cooling balm and a promise all at once.
The world outside, with its villains and its expectations, ceased to exist. Here, in their tangled circle on the floor, there was only this fragile, impossible thing they had built. A sanctuary made of calloused hands and shared breath, of competitive drives curving into something softer, something infinitely more dangerous.
Katsuki’s arms tightened around Nala, his voice a raw whisper against her hair. "Don't forget who you belong to."
It wasn't a command. It was a plea, disguised as a statement. And in the silent, understanding dark, the only answer was the press of their bodies, holding the chaos of the world at bay, for just a little while longer.
