Chapter Text
The storm did not simply arrive at Aldercrest — it assaulted it.
Wind tore against the cliffside castle with deliberate violence, shrieking through narrow tower slits and snapping dragon-stitched banners until their seams strained against iron poles. Rain lashed the pale stone spires in relentless sheets, washing over ancient sigils carved into the walls centuries ago. Lightning split the sky in blinding veins of white, illuminating the jagged sea far below where waves slammed into the cliffs as if trying to drag the entire fortress into the depths. For a brief, searing instant, the castle stood exposed in harsh brilliance. Then darkness swallowed it whole again.
In the villages below, whispers traveled faster than the storm.
They always did when the weather turned like this.
They said the princess had been born beneath a solar eclipse. That the sky dimmed unnaturally when she first cried. That glass shattered in the royal nursery before anyone touched it. That flame bent toward her hands as though it recognized its master. They said stone cracked when her temper slipped. They said the last guard assigned to her tower walked away pale and shaking. They said another left with his arm broken in a way no healer could fully explain.
They said she was cursed.
Inside the throne room, the air was heavier than the storm outside.
Torches lining the walls flickered low, their flames tinged faintly green at the edges — subtle, but noticeable. Nobles stood in tight clusters, silk whispering against velvet as their murmurs carried cautious weight. The storm was loud beyond the stained-glass windows, but inside, it was the silence that pressed hardest.
Queen Inko sat upright upon her throne, emerald gown flowing in dark folds threaded with silver. Her posture was composed, immaculate, but her eyes were sharp — aware of every shifting glance in the room.
Katsuki Bakugou stood below her, boots still damp from crossing the courtyard.
She did not kneel.
Leather straps crossed her torso in practical lines meant for movement, not decoration, and the fur-lined crimson cape resting at her shoulders shifted faintly with each draft. The thin scar along her cheek caught the torchlight as she lifted her chin slightly, bracelets at her forearms chiming softly when she flexed her fingers.
“You were summoned personally,” Queen Inko said, her voice steady and controlled, echoing faintly against the high stone walls of the throne room. Her emerald eyes glimmered in the torchlight, sharp and unyielding, catching the gleam of the silver thread woven into her gown. “Not as an honor.”
Katsuki’s smirk tugged at her scarred cheek, but she didn’t bow or kneel. She let the words linger, measuring the queen’s expression before responding. “I figured.” Her voice was flat, precise, but there was an edge to it—something that carried the weight of experience and danger.
A few nobles shifted uncomfortably in their seats, collars tight against the rain-damp air. One muttered under his breath, another avoided her gaze altogether, as though they might vanish if they ignored her presence.
“You are being assigned as personal guard to Princess Izuku,” Queen Inko continued, letting her words fall like iron weights.
The hall seemed to contract around Katsuki. A ripple of tension moved like a tangible thing, a pulse through the stone and the air. Someone near the back inhaled sharply. Another fidgeted with the hem of her gown. Katsuki didn’t flinch.
Her jaw tightened, scar twitching faintly. “I don’t guard ornaments,” she said, letting her words land deliberately.
The queen’s gaze sharpened, unwavering. “She is not an ornament.”
Katsuki crossed her arms over her chest, the leather creaking softly. “Then why,” she asked evenly, “have three guards already failed?”
Silence fell, thick and heavy. Every whisper in the hall seemed to die midair.
“My daughter does not cooperate,” Queen Inko said carefully, deliberate with every syllable. “She does not respond to authority she does not respect. And she does not tolerate weakness.”
Katsuki’s eyes narrowed slightly, the scar along her cheek catching the torchlight. “Sounds like she’s the problem.”
A noble muttered something under his breath. The queen didn’t acknowledge him. Her calm gaze remained fixed on Katsuki, unflinching.
“The court fears her power,” Inko continued. “They mistake control for volatility.”
“And you?” Katsuki asked, leaning slightly forward, hands brushing the edges of her bracelets, alert and ready.
“I know what she is capable of,” the queen said quietly, voice low enough that only Katsuki could hear. “Which is why I need someone who will not cower.”
Katsuki’s lips twitched, almost a smirk, almost a snarl. “I don’t fear princesses.”
“Good,” Queen Inko said, calm but piercing. “Because she does not fear you.”
The dismissal was subtle but final. Katsuki gave a short nod, fingers brushing the edge of her cape as she turned, boots echoing against the stone floors. Even as she left the throne room, she could feel the weight of the court’s unease pressing between her shoulder blades. It followed her like a shadow, heavy and persistent.

The barracks smelled of oil, leather, and heated iron. The air clung to her skin in a thick, almost comforting heat after the damp chill of the storm outside. Mina lifted her head immediately, pink eyes glinting with curiosity and mischief. “That face means something dramatic,” she said, voice bouncing slightly in the tight room.
Kaminari groaned from the far cot, stretching and dragging a hand through his hair. “Tell me it’s not tower duty again. Please. Just tell me it’s not—”
“It’s her, isn’t it?” Kirishima cut in, elbows resting on his knees, jaw tight but serious.
Katsuki removed her gloves slowly, letting the leather snap lightly as she flexed her fingers. Her bracelets jingled faintly, a soft warning in the warm room. “Personal guard,” she said, voice low and even.
Mina’s eyebrows shot up. “No way.”
“The cursed one?” Kaminari added, sitting up straighter, leaning forward with barely concealed awe.
Kirishima shot him a glare sharp enough to split stone. “Don’t call her that.”
“It’s what everyone calls her,” Mina said, tilting her head. “They say she bent a blade without touching it.”
“They say she cracked stone,” Kaminari added, excitement flickering in his eyes.
Katsuki rolled her shoulders once, leather creaking with motion, cape brushing her back. “Then the last guards shouldn’t have gone in scared. Weaklings.” Her scar twitched faintly, and she glanced at each of them with sharp, assessing eyes.
Mina tilted her head. “You hate royalty.”
“I hate fragile,” Katsuki said simply, strapping her cape across her chest. Her fingers brushed the fur at her collar, adjusting it as if armor for the storm to come.
Kirishima gave a thoughtful hum. “If she’s difficult, you won’t back down.”
“She doesn’t have to like me,” Katsuki said, tightening her grip on the leather straps at her shoulders. “She just has to listen.”
Kaminari snorted. “You really think she listens to anyone?”
Katsuki’s smirk was slow, deliberate, and sharp. “She will.”

The spiral staircase wound upward like a slumbering serpent, stone slick beneath her boots. Wind whispered through narrow slits in the wall, tugging at her cape and carrying the faint tang of salt and storm from the sea below. Each step pulled her higher, and the sound of the storm faded beneath layers of stone, replaced by a quiet hum, almost imperceptible but undeniably alive.
Wards. Protective, watchful, waiting.
The upper corridor stretched impossibly long, torchlight flickering across carved gargoyles and runes etched deep into the walls. Every surface seemed to breathe faintly, subtle vibrations brushing against her bracelets. She kept her shoulders straight, hand brushing against the hilt of her sword at her hip, cape fluttering in quiet resistance to the gusts slipping through cracks in the stone.
At the corridor’s end, the doors appeared, massive and imposing. Dark oak carved with twisting dragons and serpents, bodies woven into ancient sigils. Faint green light pulsed along the engravings, like veins carrying slow, deliberate power. The castle itself seemed to lean closer, testing her, gauging her presence.
Katsuki slowed only slightly, scar twitching, canines peeking faintly as she exhaled. She stepped forward.
The double doors groaned as they swung open, green light spilling into the corridor, illuminating the intricate sigils carved deep into the oak. Wind tore through the chamber, whipping at Katsuki’s cape and rattling her necklaces. She stepped inside cautiously, boots striking stone softly, ears attuned to the subtle hum of magic that clung to the walls like a living thing.
The room was alive. Books hovered midair in uneven, restless circles, pages snapping against one another. Candles burned with emerald flames, stretching thin and flickering as if reacting to her heartbeat. Vines slithered along the curved walls, flowers opening and closing in silent rhythm, almost like the room itself was breathing. Every surface thrummed with energy, teasing her senses, testing her presence. Katsuki’s fingers brushed the edge of her sword, gripping it lightly, her stance deliberate, poised.
At the center of the chamber stood the princess. Barefoot, small yet radiating an intensity that made the air hum around her. Her dark curls were wild, yet somehow purposeful, framing a freckled face that looked almost delicate against the raw force she projected. Green eyes, vivid and sharp, locked onto Katsuki’s with unwavering focus.
For a heartbeat, they simply stared at one another. The room seemed to hold its breath, the storm outside muffled behind layers of stone and wards. The green light from the sigils shimmered along the walls, creeping along the floor toward Katsuki as if drawn to the tension in her stance.
Then a book shot across the room, twisting midair as if guided by thought. It struck the wall beside Katsuki’s head with a crack that made dust fall in lazy spirals. The force of the impact carried no hesitation — a warning more than an attack. Katsuki didn’t flinch; she flexed her fingers on the hilt of her sword, scar twitching faintly under the lightning’s glare. Her eyes flicked to the princess, sharp, assessing.
“Leave,” Izuku said, voice low, even, but threaded with authority that vibrated through the room. Her words were calm, but there was no question of tolerance. Katsuki could feel the edge of them in her chest, pressing against her ribcage like the weight of the castle itself.
Katsuki’s smirk was slow, deliberate. She exhaled softly through her nose, letting the tension build just slightly, letting the room settle around them. “That your greeting?” she asked, eyes sweeping over the chamber — the books, the vines, the green flames stretching toward the ceiling — before returning to the princess.
Every book snapped shut at once. The air compressed further, humming with raw energy. Candles flared higher, vines tightened slightly along the walls. Magic pulsed and rolled in visible waves, testing her reaction, brushing against her arms, tugging faintly at her hair. Katsuki shifted her stance, letting her fingers graze the hilt again, bracelets jingling softly. She flexed her knees, coiled and ready, scar twitching with awareness.
“I did not request another guard,” Izuku said, jaw tight, though her posture remained fluid, composed. Fury hummed beneath her calm, barely contained, stretching into every corner of the room. “Especially not one who walks in like she owns the place.”
Katsuki’s hands rested lightly on her hips, fingers brushing her leather top, cape flaring slightly with the magic-tinged wind. “The doors closed behind me,” she said, voice low and deliberate, letting the weight of her words hang. “Good. Because I don’t need permission.”
A chair lifted into the air slowly, drifting toward her. Katsuki’s eyes flicked to it, tracking its motion, calculating. She stepped forward, striking it aside midair; splinters flew, stone beneath them groaning faintly. Every muscle in her body tensed, necklaces clinking softly. Her eyes met Izuku’s, unwavering, unflinching.
“I break guards,” Izuku said, calm, deliberate, each word carrying measured power.
“Then try,” Katsuki replied, voice low, sharp, laced with amusement. Green flames curled along the walls, vines tightened, and the room pulsed, alive with their mutual hostility. The hum of the wards grew louder, brushing at her sleeves and hair, a subtle warning: this room was not just a room. It was a challenge.
They stood still for a long moment, two storms contained within stone walls. Breaths came slow and deliberate, chest rising and falling in rhythm with the invisible currents of magic. The air quivered between them, charged, electric, like a blade hovering just before impact. Neither softened. Neither moved first. Neither yielded.
The tension thickened, pressing against her skin, tugging at her sleeves, swirling in her hair. The chamber seemed to pulse in response, alive and aware, as though holding its breath for the first true clash of wills. And in that silence, in that charged, impossible stillness, it became clear: neither princess nor guard would be the first to falter.
