Chapter 10: Rivalry and Rising Flame
The stone archway of the Demon Slayer Corps headquarters felt colder than the night air after the festival’s warmth. Anne paused just inside, the oversized tanuki plushie a soft, absurd shield against the sudden austerity. Giyu and Sanemi stood frozen on either side of her, the moon casting long, stark shadows that seemed to physically push them apart. The silence wasn’t peaceful; it was a taut wire vibrating with unspoken challenge.
"Well," Anne chirped, her voice overly bright, shattering the brittle quiet. "Thanks for the escort, gentlemen. Sir Tanuki and I are safely home. Don’t stay up arguing about patrol routes!" She didn’t wait for a response, already stepping away, her sandals whispering on the stone floor. She felt four intense eyes burning into her back – Giyu’s deep, watchful stillness and Sanemi’s sharp, possessive heat – a disconcerting prickle between her shoulder blades. She quickened her step, turning the corner towards the dormitory wing, the cheerful plushie bouncing slightly with each stride. Only when she was sure she was out of sight did she sag slightly against the cool wall, letting out a long, slow breath that fogged in the chilly air. Boys.
The predawn hour painted the compound in shades of deep blue and charcoal, long before the clang of the training bell. Frost silvered the edges of the vast central training ground. Anne slipped out of the silent dormitory, a wraith in simple training garb – dark leggings, a fitted tunic, her long hair pulled back in a messy, functional braid. She carried only her standard-issue Nichirin sword. Sir Tanuki watched her go, propped lopsidedly on her thin pillow.
The air was knife-blade cold, searing her lungs with each breath. Perfect. Silence pressed in, broken only by the crunch of her tabi boots on frosted gravel and the distant hoot of an owl. She needed space. Air. To move without the weight of hidden eyes, the simmering tension that had crackled on the moonlit path. To push herself beyond what anyone expected.
She found her spot: a secluded corner of the grounds, shielded by tall bamboo groves on one side and the high stone wall on another. The packed earth was hard, unforgiving. She closed her eyes, centering herself. The memory of festival lights and laughter felt like another world. Here, there was only the chill, the quiet, and the thrum of her own power, tightly leashed beneath her skin.
She began slowly, running through the foundational Water Breathing katas Giyu had drilled into her. Her movements were fluid, precise, a silent dance in the half-light. But it wasn’t enough. The frustration from the festival, the push-pull tension with the Hashiras, the constant vigilance of hiding her true nature – it simmered beneath the surface, demanding release. She needed something more.
She slowed her breathing further, sinking into a deeper stance. Not Water. Not the structured flow Giyu embodied. Something wilder. Earth. She focused on the ground beneath her feet, the ancient, unyielding stone and soil. Power coiled, thick and heavy, in her core. She swung her blade downwards in a controlled arc, not with the sharp slice of water, but with the deep, grounding force of stone.
Thud. A faint tremor rippled outwards from the impact point, cracking the frost on the earth in a small starburst pattern. Dust puffed into the cold air. A satisfied hum vibrated in her chest. Good. Solid.
Now, the other. Air. Swift, unpredictable, cutting. She remembered Sanemi’s raw, aggressive blasts of wind during sparring, the way they could shred targets. She wouldn’t mimic his fury, but the principle… She adjusted her grip, lightened her stance. As she swept her blade horizontally, she pushed, not with muscle alone, but with a focused exhalation, a silent command to the air itself. A sharp, whistling gust erupted from the blade’s path, whipping dust into a miniature vortex that tore across the ground for several yards before dissipating.
Earth and wind. Opposites. Could she…?
She flowed into a combination. A low, grounding sweep imbued with earth’s weight to disrupt balance, immediately followed by a high, whipping slash infused with wind’s razor edge. The transition was awkward. The earth energy lagged, making the wind slash feel weak, disconnected. She frowned, resetting. Tried again. Faster. The earth pulse was stronger this time, the wind sharper, but they still felt like separate actions clumsily glued together, not a unified force. Her breath hitched with exertion, pluming white in the frigid air. Sweat beaded on her temples despite the cold.
Fuse them, she demanded silently. Not separate. Together.
She visualized it. The unshakeable foundation meeting the untamable current. She poured her focus into the next downward strike, channeling the dense, anchoring power of earth through the movement itself. Then, without breaking the flow, she twisted her wrist, pivoting her hips, and unleashed the horizontal slash. But this time, she didn't just add wind; she let the momentum of the earth-strike propel the wind, let the wind carry the weight.
The effect was startling. Her blade didn’t just whistle; it roared. A visible shockwave of compressed air, thick with disturbed dust and grit, blasted outwards from the slash. It didn't just cut; it pulverized the frozen earth in a line ten feet long, throwing up a miniature storm of dirt and pebbles that rained down with a sound like heavy rain, leaving a raw, ragged scar on the training ground. The force of the release kicked back, jarring her arms and nearly making her stumble.
Anne stood panting in the settling dust cloud, staring at the devastation. A slow, exhilarated grin spread across her face, fierce and bright in the grey dawn. Yes. That was it. Messy. Unrefined. But powerful. Raw potential sang in her veins.
High on the covered walkway overlooking the training ground, unnoticed in the deep pre-dawn shadows, two figures stood utterly still.
Giyu had arrived first, drawn by an unnamed restlessness and the faint, rhythmic sounds of pre-dawn practice. He’d expected basic katas. Not… this. His dark eyes, usually so impassive, were wide, taking in the cracked earth, the swirling dust motes catching the first weak rays of sunlight. He’d seen her early morning practices before – dedicated, skillful, but confined to Water Breathing forms. This… this was something else entirely. Something wild and untamed that resonated deep within him, bypassing logic, stirring a primal recognition. The raw power in that fused strike – earth and air made manifest through steel – was breathtaking. A profound, unexpected awe settled over him, silencing the usual clamor of thought. She wasn't just practicing; she was creating.
Sanemi had slipped onto the walkway moments later, drawn by the unusual, concussive thump that had echoed through the silent compound. He leaned against a wooden pillar, arms crossed over his scarred chest, his expression initially one of sharp annoyance at being woken by the noise. Then he saw her. Saw the dust plume, heard the roar of displaced air. Annoyance vanished, replaced by intense focus. He recognized the wind. The cutting edge, the displacement. It wasn't his own brutal style, but it was unmistakably wind. Powerful, controlled… yet fused with something else. Something heavier. Something that made the earth itself tremble. He squinted, trying to parse it. Earth Breathing? But it moved with the wind, propelled it. The complexity, the sheer unexpected fusion, hit him like a physical blow. It wasn't just strength; it was terrifying, innovative genius. A reluctant, fierce respect warred with a spike of something hotter, more possessive, in his chest. His knuckles whitened where they gripped his biceps.
Neither Hashira moved. Neither breathed. They watched, captivated, as Anne, oblivious, reset her stance. She wiped sweat from her brow with the back of her hand, her chest rising and falling rapidly. She examined the scar she’d torn in the earth, a look of fierce concentration mixed with satisfaction on her face. She was utterly compelling in her focus, bathed in the first golden rays of the rising sun piercing the compound walls, dust motes dancing like stars around her.
Giyu felt the familiar ache beneath his ribs intensify, but it was different now. Less jealousy, more… reverence. And a dawning, chilling fear. Talent like that, power so raw and unique… it would draw more than just admiring glances. It would paint a target on her back larger than any demon mark. The need to protect her warred violently with the awe of her display.
Sanemi’s mind raced. How? Where had she learned this? Was this why she’d joined the Corps? To hide this? The implications were staggering. The Wind Pillar in him recognized a kindred force, but the man saw something infinitely more dangerous and alluring than he’d ever imagined. His usual aggression coiled inwards, transforming into a sharp, calculating focus. He needed to know more. He needed to test that power himself.
Anne took a deep, steadying breath, raising her sword again, preparing to attempt the fusion once more, to refine it. She glanced towards the thick bamboo grove, then upwards towards the high stone wall, her senses, honed by both training and hidden power, suddenly pricking.
She froze. Not looking directly at the shadowed walkway, but feeling it. The weight of attention. Heavy. Intent. Two distinct presences, locked onto her.
The exhilaration of her breakthrough vanished, replaced by an icy plunge of dread. Her grip tightened on her sword hilt, knuckles paling. The dust settled. The morning air, suddenly, felt very cold. She slowly turned her head, just enough, her large brown eyes scanning the deep shadows beneath the walkway’s roof, her heart hammering a frantic rhythm against her ribs.
Who’s there? The unspoken question hung heavy in the silent dawn. The light revealed the devastation at her feet, but the shadows above held their secrets tight.
The packed earth beneath Anne’s feet felt suddenly treacherous, the raw gash she’d torn a glaring accusation. That intense, focused regard from the shadowed walkway prickled across her skin like icy needles. She didn't need to see them to know. Giyu’s quiet, assessing weight. Sanemi’s fierce, analytical heat. Both had witnessed her lapse. Her secret crackling to life on the predawn air.
Her smile felt brittle as she deliberately sheathed her sword, the snick loud in the frozen silence. She dusted off her training pants with exaggerated nonchalance, refusing to glance upwards again. "Well," she murmured to the scarred ground, her voice deliberately light, "that’ll need raking." She turned and walked away, forcing her stride to remain loose, unhurried, towards the bathhouse. The phantom weight of their stares pressed between her shoulder blades until she turned the corner. Only then did her breath shudder out, cold vapor pluming. Idiot.
The warm water of the bathhouse did little to ease the tension coiled in her shoulders. She scrubbed the dust and sweat away, her mind racing. How much had they seen? How much had they understood? The raw fusion, the elemental surge – it wasn't a known Breathing Style. Questions would come. Denial felt flimsy. Truth was impossible. She sank lower, bubbles obscuring her tan skin, the scent of cheap soap failing to calm the storm inside. She needed a different kind of armor today.
Hours later, the clatter and chatter of the Corps mess hall felt jarringly loud. Anne pushed through the heavy wooden doors, Sir Tanuki momentarily forgotten back in the dorm. She’d chosen the cream one-shoulder top again, its soft drape familiar, paired with a dark mini-skirt that swished just above her knees. Knee-high socks hugged her calves, practical yet playful against the sturdy sandals. Her long brown hair, washed and dried, fell loose and bouncy around her shoulders, catching the harsh lantern light. She felt exposed, vulnerable after the dawn’s revelation, but determined to project her usual magnetic warmth. Heads turned, conversation dipped slightly, then surged again as she offered easy smiles and waves towards Tanjiro and his boisterous group crammed around a long table.
Her gaze swept the room. Sanemi was absent, likely brooding or training off his frustration. Then she saw him. Giyu sat alone at a smaller table near the back wall, methodically eating a bowl of rice, isolated in his own bubble of quiet intensity. The contrast between his stillness and the hall's noise was stark. An unexpected pang hit her – the memory of his hands lifting her effortlessly, the way the festival light had softened his eyes. She weaved through the tables, ignoring the curious glances, and slid onto the bench beside him without invitation.
"Hey, Water Hashira," she said, her voice warm, aiming for casual. "Saving this seat for someone grumpier than you?" She picked up her chopsticks, reaching for her own bowl of steaming rice and vegetables. Her fingers trembled slightly, the strain from the wild elemental fusion and gripping her sword vibrating deep in her knuckles and wrists. Pain shot up her forearm as she tried to close her fingers around the smooth wood. The chopsticks clattered uselessly onto the lacquered tray.
Giyu paused mid-bite, his dark eyes shifting to her hands. He saw the minute tremor, the way her fingers refused to curl properly. He didn't speak. He simply lowered his own chopsticks. His gaze flicked around – Tanjiro was laughing loudly at something Inosuke shouted, Zenitsu was fretting over spilled tea. No one was looking their way.
Slowly, deliberately, Giyu picked up a small cluster of rice and a piece of simmered radish from her bowl. His movements were economical, precise, the same focus he applied to sword forms. He held them out towards her. His expression remained impassive, but the intensity in his eyes held hers, a silent question, a challenge almost.
Anne hesitated, the intimacy of the gesture stealing her breath. The mess hall noise faded for a heartbeat. She leaned forward slightly, her lips parting. He placed the food gently into her mouth, his fingertips brushing her lower lip for a fraction of a second. Warmth bloomed where they touched, chasing away the chill of the morning’s fear. She chewed, the simple food suddenly tasting complex, her gaze locked on his.
"Thanks," she murmured, swallowing. Her voice was softer now. She glanced down at her traitorous hands resting uselessly in her lap. "Guess I pushed a bit hard earlier." The understatement hung heavy between them, loaded with the unspoken dawn encounter.
He picked up another bite. "Demon," he stated quietly, his voice rough gravel. He fed her again, his gaze unwavering. His proximity was a solid, anchoring presence against the chaos of the hall, against the whirlwind inside her head. Each gesture was practical, devoid of overt tenderness, yet devastatingly intimate in its quiet necessity. The world narrowed to the space between them, the shared bowl, the rhythm of his hand moving to her mouth.
The clatter of the hall slowly seeped back in as the immediate tension eased. He fed her the rest of the meal in companionable silence, broken only by the soft sounds of eating. When the bowl was empty, Anne took a deep breath, the lingering warmth of his touch on her lips. She turned fully towards him, her large brown eyes serious, searching his face.
"I need a favor," she said, her voice low, pitched for his ears only. She kept her expression open, friendly, but a new layer of intent sharpened her gaze. "There’s a party. Up at the royal pavilion overlooking the western valleys next week. Lots of nobility, officials." She paused, choosing her words carefully. "The Corps has… concerns. Whispers about demonic influence trying to seep into high society. Someone needs to infiltrate, observe." She leaned in fractionally, the scent of plum blossoms and soap faint on her skin. "I’ve been tasked to go." Another beat. "But showing up alone raises eyebrows. Makes it harder to listen, to move unnoticed."
She held his gaze, the playful light in her eyes tempered by a sudden seriousness that felt alien. "Go with me?" The question was direct. "As my date. Pretend, obviously. Just… be seen with me. Blend in. Be an extra pair of eyes." She didn't mention her heritage, the way her own royal blood might resonate in those halls, the dangerous secret simmering beneath the request. "Will you? Please?"
The chopsticks Giyu had just set down lay perfectly parallel on his emptied tray. Steam still rose faintly from Anne’s bowl. The mess hall clamor – Tanjiro’s booming laugh, the scrape of wooden benches, Inosuke’s enthusiastic chewing – pressed against the fragile silence she’d created with her request. A date. Infiltration. Nobility and demons. Her pulse hammered against her ribs, loud in her own ears. She kept her expression open, hopeful, but the weight of the unspoken – her blood, her power, the sheer danger of it – pressed down like the stones of the fortress itself.
Giyu didn’t move. His dark eyes, usually fixed on some middle distance, remained locked on hers. She saw the flicker – surprise, yes, but beneath it, a rapid calculation. Assessing the risk, the implications, the sheer incongruity of him playing courtier. His gaze traced the line of her neck, the exposed skin of her shoulder where the cream fabric dipped, perhaps remembering the feel of her waist under his hands as he lifted her to reach the tanuki. His jaw tightened almost imperceptibly. The silence stretched, thin and taut.
He didn’t speak. Instead, his head dipped once. A single, sharp nod.
Relief, sharp and sudden, flooded Anne’s chest, warming the chill left by the dawn's exposure. "Really? You will?" The words tumbled out, brighter than she intended. She caught herself, lowering her voice back to its conspiratorial hush. "Thank you, Giyu. Seriously." She leaned in, the scent of ginger and soy from their meal mingling with his clean, rain-water scent. "Just… be your usual broody, intimidating self. Nobility eat that up, believe it or not." A playful spark returned to her eyes, trying to lighten the heavy air. "Think mysterious warrior aesthetic. It’ll work."
A shadow fell across their table, long and sharp-edged. The ambient chatter nearby stuttered, then died. Sanemi Shinazugawa loomed over them, his scarred chest stark under the open kimono, his spiky white hair catching the harsh lantern light like frost. He hadn’t shaved; dark stubble shadowed his jaw. His gaze, sharp as flint, raked over the scene: Anne leaned close to Giyu, her expression still holding traces of that intimate relief and playful warmth, Giyu’s barely-touched intensity focused solely on her. Sanemi ignored Anne completely, his fury a physical heat rolling off him as he fixed on Giyu.
"Tomoka." His voice was a low snarl, scraping the air like stone on steel. "You. Training grounds. Now."
Giyu didn’t flinch. His gaze slid slowly from Anne’s face to Sanemi’s, his expression shifting from that barely-there softness back to its customary blank ice. He said nothing, just held Sanemi’s burning glare. The silent challenge hung, charged and dangerous.
Anne felt the fragile peace shatter. "Sanemi," she started, her voice firm, trying to insert herself between their locked stares. "It's breakfast. Whatever it is—"
He cut her off, still not looking at her, his focus laser-like on Giyu. "Not asking." Each word was a punch. "You finished playing nice? Move." The implicit accusation – that Giyu was distracted, neglecting his duty, dallying – vibrated in the air. His knuckles were white where he gripped the edge of their table.
Giyu remained seated, utterly still except for the slow, controlled rise and fall of his chest. The indifference in his posture was its own provocation. He finally spoke, his voice low and flat, devoid of inflection. "Later."
Sanemi’s hand slammed down on the table. Bowls jumped. Spoons clattered. Tanjiro’s table fell utterly silent, heads swiveling. "Don't make me drag your ass out there, Tomioka!" Spittle flew. His other hand hovered near the hilt of his sword, not drawing it, but the threat was palpable, vibrating in the sudden hush that had fallen over their section of the hall. "You think that little dust-up at dawn makes you too good for a real fight?"
Anne shot to her feet, the bench scraping loudly. "Sanemi, enough!" Her voice cut through the tension, sharper than she’d intended, drawing gasps from nearby slayers. She planted her hands on the table, leaning towards him, forcing his furious gaze to snap to her. Her large brown eyes blazed, not with fear, but with fierce reprimand. "What is wrong with you? Have you forgotten where you are? Who you are? Act like a Hashira!" She held his stare, unflinching, the memory of his awkward softening at the festival replaced by this raw, ugly fury. Her own frustration, the strain in her hands, the weight of secrets, boiled over. "Or did you just come down here looking for a fight because you're bored?"
His eyes widened slightly, shocked by the direct attack. A muscle jumped in his jaw. He looked from her furious face down to Giyu, who remained an immovable statue, seemingly carved from the fortress stone. The humiliation of being chastised by her, in front of others, warred with the seething anger directed at Giyu. His hand trembled on the table. For a heart-stopping second, Anne thought he might actually draw his blade.
Then he snarled, a wordless sound of pure rage. He shoved himself away from the table, the force rocking it. "Fine," he spat, the word dripping venom. He glared down at Giyu. "But this isn't over, Tomioka. We will spar." His gaze flickered to Anne, a complex storm of anger, frustration, and something like betrayal in the depths. "Watch your step, Kinomoto." The warning was low, dangerous, carrying more than just a threat about the training ground. He turned and stalked away, the crowd parting before him like water before a stone.
The silence he left behind was thick and brittle. Anne slowly sank back onto the bench, her legs suddenly shaky. She avoided looking at the staring faces around them, focusing instead on the grain of the wooden table. The warmth of Giyu’s silent agreement felt distant now, chilled by Sanemi’s rage.
She felt Giyu’s gaze on her profile. She didn’t turn. After a moment, the bench shifted as he stood. She finally looked up. He was watching her, not Sanemi’s retreating back. His expression was unreadable, but the intensity was back, that deep, unnerving focus. He gave a single, fractional nod – not towards Sanemi’s challenge, she understood, but a reaffirmation. He agreed. To the mission. To the charade. To whatever storm Sanemi was brewing.
Without a word, he turned and walked towards the exit, his mismatched haori a stark banner against the stone walls, leaving Anne alone amidst the buzzing aftermath, the taste of relief now sour with apprehension, the royal pavilion looming large and dangerous in her mind.
