.·:·.✧ ✦ ✧.·:·.
The roar wasn't his. Wasn't even Musashi's, for once.
Hajime blocked the last swing on instinct—left forearm raised, Nyoi braced against his shoulder—and had already pivoted to counter when it hit. Not a strike. A pressure. His cursed energy hiccupped mid-flow and his breath caught. His head snapped east, beyond the noise and chaos, past bodies and smoke and cursed fire lifting across the valley. There, crawling into the sky above the eastern ridge, rose a black dome. Seamless. Terrifyingly still. A perfect sphere blooming like dusk from nowhere.
A Domain.
He ground his bare heel deeper into the soft mud and exhaled low. "Tch." He shifted Nyoi against his shoulder and adjusted his grip. "She really pulled it."
Mi'eisō.
Of course it was hers.
He knew that domain better than he liked now, knew the weight of its silence, the taste of its cursed water, the sick rhythm of training until his nerves felt skinned raw and his bones begged for mercy. She had dragged him inside that place again and again all summer. For testing. For beating the ever-loving shit out of him beneath a sky that didn't end.
Kaoru's voice now lived in his ear like a curse.
Again.
Again.
Again.
Hajime twitched at the memory, muscles clenching and his stomach gave a quiet, treacherous lurch. Scowling, he flicked his gaze down half expecting to see it but... No. No shadow beneath his feet.
"Right," he muttered, wrinkling his nose. "Forgot."
That damned woman, she hadn't even asked, just taken it weeks ago. Just… reached into the mirrored water of her domain and yanked it from him without ceremony. "So you can train," she'd said. "It'll be good for you."
The hell it was.
"You better make it count," he growled now, mostly to himself, gripping Nyoi a little tighter. "You terrifying bitch."
He wasn't worried, not exactly. Kaoru was the kind of person who'd gut a kami just to prove a point and complain about the mess, but if she had pulled that then something out there had come close to making her fall, and Hajime didn't like that idea at all. But now, one way or another, the fight was ending. Hers, someone's, maybe everyone's.
And whoever was in there with her? He looked toward the horizon again, eyes narrowing.
Poor bastard.
A single bead of sweat rolled past his temple and his jaw tightened. He turned back to the soaked hill, squelching through cursed water already swirling at his ankles.
"Lightning God!" Hajime blinked once, slowly. There, on a boulder slick, stood a very wet, very excited Musashi Miyamoto. His eyebrows—those kami-damned eyebrows—furrowed with melodramatic offense. "Are you ignoring me again?!"
Lightning popped quietly off Hajime's shoulder in irritation as he straightened. Rolled his shoulders. Cracked his neck. Every joint stung. Sparks hissed along the curve of Nyoi. "Right," Hajime muttered, not to idiot in front of him but to the war itself. "You."
They'd been at this for far too long.
His ribs still bled through the charred fabric of his uwagi. The right sleeve was gone, burned off somewhere in the chaos, his twin topknots long since undone, and the cursed water pooling around his legs never stilled. The skin on his thigh still throbbed from where it had nearly boiled under a wave of Musashi's cursed splash. His left eye was puffed almost shut. He shifted Nyoi behind his neck in a low guard, sparks that danced faintly, relaxed only in the way a cornered wolf was.
Musashi was in no better shape and yet, he was smiling like he hadn't just been flung through a pine tree.
He had a gash open across his temple, red trailing down his nose. His arm still gripped the broken hilt of Dokkō like it was holy. Nikkō, his other bokken, pointed at his side, slipping droplets. His uwagi that mirrored Hajime's was soaked wet and the kanji for "Miyamoto" stitched across his chest remained proudly, idiotically backward. An arrowhead stuck out on his upper arm, barely buried beneath the skin. Some Hattori's doing. Infused with corrosive cursed energy. Probably Masanari's. He'd tried to interfere in their fight to support Hajime. He'd fried the treeline for that and there had been no sign of him since.
And still, Musashi stood tall, shaking water from his sleeve like a dog, as if the tremble in his forearm meant nothing. Maybe it did. Maybe is cursed energy that flowed like water was hard to poison after all.
"Still standing, huh?" Hajime said, spitting blood to the side. "Shame."
"Unforgivable," Musashi wheezed, wiping his forehead and flinging droplets in a graceful arc. "To insult a man's poetry with your fists, and then outlast him? That's low."
"I didn't insult your poetry," Hajime replied flatly. "I insulted your face."
"Even worse!" Musashi cried, scandalized.
A beat passed. Kaoru's domain still pulsed on the eastern ridge and even if neither of them had mentioned it directly now, it hovered.
Hajime's grip on Nyoi shifted. "I don't have time for this," he muttered. "I've got someone to check on."
Musashi's grin faltered just a little. "Me neither," he admitted, grinning and lifting his chin, though his brows knit. "I haven't felt my shishō's cursed energy since that thing flared. Which means he's unconscious… or the battle's just too epic for me to comprehend!"
Another pause.
Hajime's grin turned feral. "Still not letting you win."
"Kami, no!" Musashi said with delight. "I live for this!"
That was all the warning either of them needed. They moved again—together, back into position.
Hajime dropped low, crouching in the saturated mud, lightning crawling across his arms in fracturing arcs. Water clung to him in stubborn beads but couldn't stay long; every spark of his cursed energy pushed it off in static bursts.
One good eye. One working lung. One cursed staff. Still enough.
Across the battlefield, Musashi raised his twins bokken high. Cursed energy curled around the broken length of Dokkō, flowing down and back up, forming a cutting edge. A makeshift blade of compressed cursed water.
Despite the wounds, the split lip, the blood in his teeth, Musashi stood tall. That stupid smile hadn't faded once. "Alright, Rival of Destiny," he shouted, spinning his bokken wide to splash the water in a perfect circle around them. "Let's finish our poem!"
Hajime exhaled sharply. "You talk too damn much."
And surged forward.
Nyoi sweeped from his shoulder in a savage arc—only to meet water. Again. It cleaved clean and uselessly through a veil of moisture that splashed back against Hajime's face and arms, dousing his cursed energy. Sparks sputtered and died along his forearms for the third time in as many minutes.
"Tch." His momentum faltered and he pivoted mid-slide, heels digging into the slush just as Musashi materialized behind him, that manic grin wide on his face.
"Flow forth, Mizukagami!"
Three reflections rippled into view. Illusions, refracted forms of the same opponent, each moving slightly out of sync. Swords raised.
Hajime squinted. "You're not even trying to be subtle." He struck at the one on the right and felt no resistance. Wrong. A blur moved through the mist—too fast—and the real bastard, Musashi, slipped past him like a current, vanishing into the fog.
"Fucking water," Hajime muttered, breath heavy as he stumbled two paces back. That was the problem.
The staff slid in his grip. The ground beneath him churned into soup. He could feel cursed energy twitching beneath his skin, erratic and uneven. Every time he tried to charge a pulse, the dampness in his sleeves and collar leached it out, bleeding power into the swamp Musashi called a battlefield.
Across the puddles, Musashi twirled like a dancer, droplets scattering from his long braid as he closed the distance again. "We are but rivals cast adrift in the same divine tide—"
Hajime didn't wait. He slammed Nyoi down for balance, pivoted around him lifting mid-air, and drove a kick directly into Musashi's jaw. "Shut up!" he hissed.
"Oho!" Musashi reeled back, laughing through the pain, if he ever felt any. "A strike truer than any haiku!" he sang and channeled again. "Suishōken!"
The air snapped. Three crystal-clear blades of water rose from the ground and formed mid-air floating around Hajime like shrad of glass. One descended from above; Hajime blocked it with Nyoi. The second carved from the side; he twisted away, barely grazing his hip.
The third struck clean.
A blade of cursed water sliced into his ribs triggering a Black Flash just an instant later. Not a deep wound in insight, but Hajime felt a couple of ribs cracking under the pressure of the Black Flash and that was worse. He grunted as blood flared down his side and cursed energy leaked out, pouring from the open wound. His uwagi split along the seam and blood spread across the cloth, trailing down into the wet earth.
"Shit," Hajime hissed, backing off, eyes scanning.
He staggered back, teeth clenched. His cursed energy stuttered again, drawn toward Musashi like lightning toward open sky.
No time.
The other boy leapt forward with a dramatic shout, never missing a beat. "Su—i—yō—sen!"
The kabuki war cry hit first, then the slash. Musashi came screaming in, sword trailing a high-pressure wave of cursed water like a vengeful tide. Hajime, lightning at his heels, tried to flip out of the way but not cleanly. The edge nicked across his thigh in a grazing burn that nearly knocked him flat. His leg buckled, slipping in the mud and he fell hard, shoulder-first, rolled twice, and dragged himself upright with a groan.
"Do you name every damn attack?" he grunted, breath ragged.
"Of course!" Musashi called back cheerfully.
Hajime crouched low, sucking air through clenched teeth. Lightning crackled along his knuckles and fizzled again as he ducked behind a collapsed helmet and a corpse for shield, bracing himself with one hand against his side. Blood dripped through his fingers, soaking the mud and his breathing was erratic.
His thoughts even more erratic.
Musashi wasn't slowing down. He bounced through the field like a koi with a vendetta, swinging twin swords with relentless enthusiasm. His cursed energy flooded the terrain. Hajime's own power bled with every step.
He growled low. "Brute force isn't working."
Musashi wasn't just fast. He was adaptive, unpredictable. The water refracted his presence, distorted the battlefield and yes, Hajime's fists were stronger, but they never landed right. That cursed energy—kami, it leaked everywhere.
Can't use Lightning Discharge like this. Think. Think, dumbass or you're just proving her right.
He closed his eyes, and In the darkness behind his eyelids, he could hear her condescending voice echoing: Adapt to this world or die. Kaoru's favorite lesson. And the worst part? She was right. Fine. If speed and brute force were useless, he'd try something else.
Monster thinking.
Hajime spat to the side, eyes narrowing. Lightning and water didn't mix, that was the whole problem. Unless you could guide the current. Unless you could control the path. A breath. Then another. His grip on Nyoi shifted, looser now, more like coaxing than commanding. He didn't resist the moisture seeping into his skin. He let it in. Let it fill the gaps between his fingers, crawl along his limbs. Made his body part of the battlefield.
Positive charge forward. Negative down his spine.
He didn't push lightning out this time, he stored it. Let it hum in the shaft of his weapon as the valley shuddered around him. Hajime lowered his stance, water rising around his ankles.
Okay. Let's see what happens.
He adjusted his stance, shifted weight forward, letting the battlefield become his conductor. Across the field, Musashi stood tall again, wild black hair plastered to his forehead as he raised one bokken to the sky. Behind him, the cursed water surged, writhing upward in a coiling spiral.
A dragon. Huge. A tsunami with eyes.
That ridiculous war cry rang across the battlefield like a kabuki drum:
"Seiryūka!"
The Azure Dragon. Musashi's final play. There was no way in hell Hajime could overpower that. But maybe—if water was going to drown him he'd make sure it carried lightning to the heart of that water-dragon first.
"Alright," he muttered, lowering Nyoi to the surface of the water. Sparks kissed the ripples. "Let's ride it."
The mud sucked at his feet as he lunged forward as his grin widened, hungry, unhinged. His body screamed with bruises, ribs cracked, lightning singing under his skin. Across the field, Musashi's eyes narrowed. Then widened. Hajime had stepped directly into his stance, matching his footwork, rhythm, pressure.
"Wait—are you copying me?!" Musashi shouted, horrified.
Hajime's smile turned savage, eyes glowing white-blue as lightning stored more and more along Nyoi. "No. I'm improving you."
His movements mirrored Musashi's; weight shifting, core rotating, cursed energy pulsing in rhythm. Each step condensed more charge into Nyoi and the water accepted him now, no longer fighting him but conducting. He let the negative charge pool in his gut and held it, one breath longer than instinct demanded.
Behind Musashi, the dragon reared, pressure peaking but still charging toward him like some ridiculous river kami.
"Rival—hey, are you about to—?!" Musashi blurted, voice half awe, half panic. His hair came undone with the pressure mounting behind him, now unable to stop the wave of water and destruction that came with it. "You're literally glowing!"
Hajime said nothing. He dropped into the final stance. One foot touched the waterlogged earth one last time, closing the distance between them and the whole field hummed.
Then Nyoi followed with a low, deep vibration that rippled out like a drumbeat, and struck.
"I said you're glowing!" Musashi jolted. "Are you even listening?! That's going to—"
"Shut up and watch me!" Hajime said, baring his teeth.
Lightning screamed down Hajime's arm and a jolt of cursed energy discharged from his palm, through the staff, through the water, and into everything Musashi had built. The cursed dragon welcomed the charge. For one horrifying instant, it became a conduit. A trap.
And Musashi's cursed energy sparked in response too late. He tried to backpedal, but his own technique, his own brilliant fluid Cursed Energy that had made his movements untouchable, now rippled traitorously beneath his feet.
"Wait—Don't—!"
Too late.
Hajime laughed louder, not caring as the water turned to steam and Nyoi glowed too hot in his grip.. He could feel the charge coiling in his spine, gather behind his skull, in his chest, white-hot in every nerve. "Die you fucking poet!"
Just like that, he let go.
The Lightning Discharge erupted in a perfect explosion of light and sound, a spear of white fire split the sky, centered on Hajime's body. Nyoi vibrated in his hands as the cursed current shot through the dragon, through Musashi, and into the valley beyond. Nyoi burned his palm as the water evaporated.
Steam burst in every direction, carrying screams and sparks.
The cursed dragon buckled mid-air, howling before bursting in a tide of scattered droplets and a thousand invisible veins lit up underfoot.
For one impossible heartbeat, Musashi's silhouette vanished in the light.
And then—
Another explosion cracked through the heavens. Brighter. Louder.
INot Hajime's doing; it didn't come from them. It came from the east.
A flash. Purple. It shot toward the sky swallowing the horizon and the battlefield whole, eclipsing even Hajime's lightning. The cursed energy pressured and rolled outward in a shockwave so dense it crushed the battlefield's breath. Hajime staggered a step, as the electricity in his own body went static.
Kaoru's domain exploded outward in the distance.
The battlefield froze. Even the thunder paused.
And then... silence.
For a moment—just one sacred moment—there was no thunder. No shouting. No war. Only the hiss of steam rising from cratered earthJust steam. Just the hissing ruin of a valley turned into glassy, smoking mud and the quiet hum of cursed energy receding.
Musashi crumpled across an incline, half-submerged in his own flooded terrain. The impact had turned the whole slope to glassy mud and burnt stone. What remained of his uwagi was blackened and opened on his chest, clinging wet to his skin, eyebrows singed and almot fone. His smile—cracked and ridiculous—somehow still showed at his lips even as his fingers twitched uselessly and his body didn't follow.
Still alive. Barely. But down.
Smoke curled up from his hair. One leg spasmed. He groaned, teeth pink with blood. "Hah… that was… legendary."
A few paces away, Hajime remained standing. Barely.
His entire right side trembled with overuse, his breath sawed ragged through split lips. Cyan hair crackled and lifted in static, spiked in every direction and his own uwagi burned halfway down his torso between the third shockwave and the final blow. The skin across his arms and chest skin red and scorched still steamed in the cold October air.
Barely upright and one eye swollen shut, he dragged Nyoi behind him and limped forward, looking down at his rival. He clicked his tongue, still smiling. "Next time," he muttered, half-mocking, half-respectful, "bring a second clan member, idiot."
He turned his back, but only after a breath, and only after pausing just long enough to add, over his shoulder. "You're not bad," he added as his grin pulled wider. "For a koi fish."
Musashi coughed again, laughter bubbling behind the sound as he peered at his rival from his only good eye. "Koi… can turn into dragons," he mumbled into the mud, not even mad. "I read that in a poem…"
"Figures," Hajime muttered.
He turned without another word, cursed energy still sizzling faintly in the wake of his steps. The air around him buzzed with residual electricity, crackling through his bones like second nature, no longer unstable, no longer misfiring.
His body hurt, yes, but Kami… he felt it.
Satisfaction. Not the sadistic kind. Not cruelty. Just the bone-deep, lightning-slick truth of a battle well fought. One where—for a brief moment—he'd known, with absolute certainty, that he was strong and that... Kaoru had been a pretty damn good mentor after all.
A ghost of a smirk pulled at the corner of his mouth, even as his cracked ribs protested, but his spine straightened as he walked far off, where Kaoru's domain had collapsed into dusk and purple light.
Where the final act of the damn war was playing out.
.·:·.✧ ✦ ✧.·:·.
Water.
No, the surface beneath his feet wasn't water, not exactly.
It rippled like water, shimmered like it, even gave underfoot with that ghost-soft yield of liquid tension, but cursed energy didn't move through it right. The resonance was wrong. Too still. Too perfect. Above and below: the same mirror. No sky, no sun, just reflection of shadows. Dusk without source, the kind of false twilight that made you feel like time had already ended, and no one had bothered to notice.
Even sound here dragged and echoed just a beat too long. Kaoru's voice especially.
"Gojo Seijiro," she'd raised her chin and said simply. "Your shadow is now mine forever."
Of course she said it like that. Kaoru always had a flair for drama.
"So that's how it works," Seijiro murmured, mostly to himself. His own voice came back to him warped as if it too were submerged. The irony nearly made him laugh, not from surprise; he'd known this was coming the moment she met his gaze on that slope with blood on her lips and that awful, beautiful certainty in her eyes.
His own shadow—no, not his anymore—stood in the water beside her. Not behind her, not beneath her; beside her, his own cursed reflection, rebuilt from ink and karma. It mirrored him perfectly: height, posture, the lazy sprawl of stance that screamed I'm holding back just to amuse you. The smug tilt of the chin, the earrings, even the same annoying habit of tapping a foot when he got too excited. His own cursed reflection, rebuilt from ink and karma. Kami, he hated how accurate it was.
"Well," he said, licking blood from the corner of his mouth, grinning despite himself, "I'm prettier than I thought."
Seijiro took one step forward. The surface rippled; the Shadow-Seijiro didn't. Right. No time for narcissism.
Even half-blind, the domain overwhelmed him. No wind, no scent. Just an eerie sensation of lack and the whisper of various shadows that moved through the surface almost alive. This was her world: of course it was so damn quiet.
Every motion reflected in slow delay, screaming in high fidelity. Too much information. He closed his dead side, breathing deep, forcing the tremor out of his limbs and his only one working eye do all the work of the Six Eyes. He had one arm left, maybe two minutes of clean output, and cursed energy that sputtered like it was being strangled. His back was on fire. His ribs were definitely cracked. His Six Eyes kept trying to send him warnings he was ignoring.
He hated asymmetry, but his stance was solid enough.
Kaoru hadn't shifted an inch, still standing in stillness, her breathing steady but shallow, hair soaked through with sweat and blood, clinging down her back like wet ink. Even now, even now, she was absurdly pretty in that unflinching way only the dead or determined ever achieved. There was blood at the edge of her lips, and her right arm didn't sit right in its socket, scorched through to tendon from the lightning she'd conjured like a lunatic, but she moved like it didn't matter. Like all the ugliness of the world had been set down for a moment, just to let them have this.
Her fingers dipped into the mirrored surface and from the black water rose a katana. The blade formed from pure shadow, and she tested the balance with her ruined arm.
Seijiro looked at her and felt a pang so strong it almost knocked him sideways. Of course. "I'm impressed," he smirked to himself. "Still fighting, even like this. Stubborn woman."
Her lips curved—tight, not quite a smirk but in the way they were when she was thinking too hard. She hesitated a moment longer. Then, a quiet crescent of joy rising on her bruised lips. "Let's have fun, Seijiro," she said simply, smiling through her own death.
That was the part that undid him.
It wasn't a war-mask or a weapon. Not the smirk she used in front of councilmen, not the razor-thin grin she wore when outmaneuvering generals. It was the kind of smile you gave the sea before stepping into it. Gentle. Terrible. Honest in a way he'd seen maybe… twice? Maybe once, and maybe she was eating kushiyaki. But there it was.
Seijiro stared and stared at her, stunned, like a man struck dumb in a shrine. He blinked once, and then again. Just like that, he forgot pain, forgot the battlefield, forgot every reason not to fight her. He'd been ready for hate, grief, for her to cry, even if really he should know better, but not... this.
She looked happy.
"…You've completely lost it," he chuckled, and help him, he loved her so much for that, it felt like the last great cosmic joke.
Kaoru took her stance, the Shadow-Seijiro doing the same beside her. "It's our last," she said, grinning wider, as if they were just sparring in a training hall. "When else will we get to go all-out? Since we must die, let's live a little at the very end."
He laughed, a joy-raw laughter that made his ribs scream but felt more alive than anything he'd felt since... he couldn't remember. It sounded terrible and perfect. "Alright, Pretty Boy," he said, sliding into position. "Who am I to deny a beautiful woman one last fight?"
Seijiro's good eye flicked toward the shadow again, Six Eyes feeding him every bit of information. "So? Does that shadow-me follow the same rules as your other shikigami?" he called out, loud enough for her to hear, even if he was half-talking to himself. "Bound to the Ten Shadows' rules? Can it break?"
No answer; typical. But her knuckles twitched slightly where they rested against her blade.
So. Yes.
"Figures," he muttered casually. "My output's fucked."
He flexed his fingers once, felt the ache run through burned nerves and scorched muscle. His Infinity pulsed crooked, off-beat, his cursed energy was still misaligned after the Domain clash.
Limitless wasn't happening like this. He needed a reset; a jumpstart.
The shadow rushed him first, his own stride mirrored back at him, smug expression intact. It collided with him in a blur, fist sparking with Blue arcs across the water-mirror beneath them. Seijiro ducked a high kick, ribs screaming as he slammed a counterpunch into its gut, only to collide with the shaodw's Infinity. He ate a blow across the jaw an instant later.
Seijiro's grin split. "Messy," he breathed.
Then—luck. Or divine comedy. Or maybe just spite. His own fist connected square with the shaodw's jaw and black lightning snapped against the mist; he could feel as his cursed energy surged back into sync, and the universe snapped into alignment.
Black Flash.
The water beneath their feet detonated outward in concentric rings, steam exploding skyward as his Black Flash drove the shadow's head sideways in a spray of warped light. For an instant, everything bent—time, space, pain—and Seijiro felt his whole system reboot; his cursed energy flooded back, clicking into place the right way.
He staggered back, gasping, shaking out his hand like it hurt too good. "Kami bless my bullshit luck," he wheezed, grinning like a teenager. He raised his hand, slow, deliberate, savoring the symmetry of the moment. Half-blind. Half-dead. "Phase." A pulse of cursed energy at his fingertips. "Pāramitā." The mirror-water beneath him trembled. "Pillar of Light."
Blue bloomed beneath his heels and he popped forward as the surface split under him. Water fractured. His body moved before his brain caught up, closing the gap with Shadow-Seijiro. Their eyes met; his eyes, just... colder. They stopped a handspan apart as he leveled it point-blank at his smug shadow's face. One clean shot; he'd incinerate it before it had a chance to react.
At point-blank Seijiro's hand lit with cursed energy lifted toward his shadow's head. "Cursed Technique Reversal: Red."
The shadow clone mirrored him instantly and its Red bloomed to match his. The air around them folded as the two reds detonated mid-air between them, boiling the water into steam and sending both figures skidding backward across the surface.
Seijiro staggered back, coughing through the smoke. Pain lit up his already-wounded side and his vision warped from the heat. "Less creative than me," he wheezed, eyes narrowed through the haze. "But, kami… tight form."
He squinted into the mist, shapes flickering in and out of focus, cursed energy stabilizing just enough for the next round. The explosion had reset the field into mist. Small mercy. But—
Kaoru was gone.
Shit. She'd waited for the distraction.
The next instant, the Shadow-Seijiro emerged from the steam, smiling that same smug, punchable smile, another Red already gathering at its fingertips. "Oh fuck off," Seijrio grunted, as he flung up a half-baked Blue with his off-hand, just enough to dampen the blast away, then teleported behind the shadow in a pop of compressed space.
The shadow spun mid-air, its palm crashing against his chest with a Blue-infused strike. Infinity gave, and Seijiro had no time to think if it was because that thing was actually him because he was thrown backwards, steam hissing around him. He landed in a crouch, turning mid-slide and preparing another charge just in time to sense—
Slice.
Kaoru was there. Real Kaoru, rising from her shadow and sweeping in from his blind left. The air behind him bent as her blade came toward his ribs, pulled upward with a fluid grace he remembered far too well and no warning. She was so close he could feel her breath stir the space in front of his lips.
He parried on reflex, cursed energy flooding his forearm, just enough to absorb the hit feeling the pressure of her blade agains him. Great, now he was fighting two. And worse, he loved this.
"Hey," he grunted, sliding back a pace, as he lunged at Kaoru, aiming high with a Blue-infused fist. "I'm the only one allowed to look that smug."
She didn't rise to it, just pivoted as with the flat of her blade she parried his fist, the shadows rippling inside the katana and her burned shoulder twitching. "Someone has to humble you."
His grin split wider. "That pivot—'Nobu teach you that?"
"No." She ducked his swing, twirling away with ease in the water. "You did."
Seijiro stumbled slightly. "Oof. Brutal."
Kaoru spun again, blade slicing upward, and he barely caught it in time. "You still favor your left guard," she teased with a quick breathless laugh. "Sloppy."
"And you still telegraph your pivots," he shot back, just as breathless. As they bantered, his mind never stopped working. Her strikes, they had all been real swings, sure, but...
No sure-hit effect on her, he noted. That means—
Her downward strike left him open for just one breath and his eyes widened—just slightly—when Shadow-Seijiro teleported just above him, timed to perfection and seizing the moment. Seijiro dodged left, ducked low, spun into a crouch as the shikigami-version of himself dropped a Red from above like divine punishment.
The sure-hit effect applied to the shikigami made sure Red collided mid-spin with his arm, just under the shoulder. He threw his hand up to redirect, cursed energy-infusing his palm just in time to deflect, but the impact still hit, surging through bone and tendon, setting skin and muscle ablaze. Pain flashed white. His cheek sizzled, the scent of burning flesh curling into the still air and something popped inside his ear.
And still—he grinned. Because, even with his face bleeding, and his ribs cracked, his gaze jerked up, half-lidded and caught the change on Kaoru's face. Her eyes widened, her grip faltered. Guilt, fear and conflict, plain as sunrise. She took half a step toward him before catching herself.
Oh, he thought, dizzy with affection. There it is. The puppy face. He didn't mock her for it; she was fighting seriously and that was all that mattered. But that hesitation? He took it.
Seijiro didn't wait—he pulled himself backward with one final burst of Blue, resetting the field.
So. He tilted his head, mock-pouting, breathing hard now. The sure-hit effect was on the shikigami, not her; that much was clear.
The clone could use Limitless, and it was terrifyingly good at it. Every detail down to his cursed output, his cooldown patterns, his decision trees, it was like fighting a version of himself without hesitation.
But not like me-me.
Not creative. Not human. It followed a script, probably the one stolen along his shadows. It couldn't evolve.
And Kaoru? She was moving much too little. Not defensive, not passive. In control. She was the anchor and she never moved too much when the shikigami attacked. Which meant she was focusing very hard, keeping too many plates spinning at once. Maintaining the domain, a newly acquired shikigami, battlefield control. She was strong, bu that kind of strain? Even she had to focus to control all of that. And that left her vulnerable.
That's my opening. He grinned. He could break her balance. Fine. Time to get messy.
Seijiro blurred forward mid-air, dismissed the shadow with a feint, then launched himself upward in a spiraling arc using Blue-enhanced footwork, aiming straight at Kaoru, straight at the center point in the Domain.
Kaoru looked up a half-second too late. Blinked, surprised, just in time to see him raise a hand—
"Hi," he said sweetly, before dropping a Red straight down at her from above.
Boom—
The blast clipped her thigh. She pivoted, blade flying up, but the explosion caught her just off-center. Steam burst upward, blood misted into the air, and Kaoru stumbled into a crouch, her balance shaken.
Seijiro landed in a three-point stance across from her, arm trembling. "Got you," he panted, grinning "You were distracted."
Kaoru glanced down at her thigh, where blood slid in thin rivers down her leg, but she didn't look mad. She grinned. That radiant, reckless grin. "Oops," she said, brushing damp hair from her eyes. "My bad."
Her next move came fast, too fast. She dipped into the steam still rising between them, vanishing behind the mist like a trick of light, disguising her shadow. Seijiro tensed, and water sloshed from the right—his good side.
"Cheeky," he muttered. Seijiro's instincts screamed.
If she was coming from his good side—
—then something else was coming from the blind one.
He didn't think, just leaned back, spine folding like a whip, as Kaoru's blade skimmed the air above his chest. At the same time, his fist swung low and left, cursed energy flaring Blue; it collided with something solid and a low growl answered him.
"Divine Dog?" he huffed, stumbling a step back as the shikigami yelped and went tumbling into the shadow-water. A scratch ran bright and red along his arm. "So you can still use your basic summons."
Kaoru burst from the shadows in the water, behind him, katana whistling through the air.
Seijiro ducked, blocking with his elbow. "You and your sneaky little combo moves," he chided. "Predictable."
She puffed her cheeks in mock indignation, disappearing again inside the shadows. "Not sneaky. Strategic."
"Yeah, yeah." He side-stepped as Divine Dog lunged again low, aiming at his legs, leaving another slash along his calf. "Say that when you're not hiding behind a mutt."
Kaoru exploded out from the shadowed lake again, sword flashing upward, Divine Dog tracking just behind her like a well-trained partner. In and out of the mirror-surface, it snapped and vanished with every step. Seijiro's arms moved faster than thought, parrying each blow, limbs reinforced with cursed energy but still screaming at the impact.
Seijiro pivoted, Kaoru ducked. She knew he could tank her, and knew he'd try to grab her arms if she got too close. So she stayed low. Tight.
Their rhythm slipped into something too old and familiar, sparring like they were still two young and stupid heirs with too much pride and too little sense, and not two Clan Heads at war. She cut across his guard, ducking under his extended arm, using her smaller frame the way she always did against men bigger than her: not as a limitation, but as a goddamn weapon.
Seijiro tried to reset, but the dog was already circling behind. One sweep—
Splash.
He fell hard flat on his back.
Water seeped up around his shoulders and neck as his limbs skidded out beneath him, the steam parted... and Kaoru landed over him in a single, breathless motion. Straddling his hips, blade at his throat pressed just enough to make a point. Her face inches from his. She was breathing hard, eyes bright with the kind of focused, delighted madness that probably mirrored Seijiro's.
There were moments in life where Seijiro Gojo, for all his ego, admitted he was not the smartest person in the room.
This was one of them.
He blinked up at her, dazed, half-laughing. "How," he chuckled, "how do I always end up like this? With you on top?"
Kaoru flushed just a little, but didn't move. "Don't make it weird."
He could feel her legs pinning his waist with that ridiculous strength she never acknowledged, like she didn't know her thighs were made of steel. "I swear," he murmured, smirking, and a little too fond "you have the scariest legs in the whole country."
"Seijiro," she scowled harder, pressing the blade closer—not cutting, just a warning—but her cheeks were redder now. She didn't move but she looked genuinely unsure what to do with her face.
"What? You do," he said innocently, wincing as she shifted. He grinned up at her like he always did, entirely unbothered. "They're like—steel traps."
He let his head fall back into the water, eyes fluttering shut for a second and silver hair floating loose from their tie. His arms sank back into the water soaking like he'd just given up. For a second, as her cursed energy wrapped around him like a blanket, he felt like he could sleep there.
It felt like home.
A beat. Then another. They stayed like that for a long moment, cursed water lapping gently around them. Still and strangely peaceful.
She was still looking down at him, so he looked back up at her, the corners of his mouth softening. "Beautiful."
Kaoru blinked, confused. "What?"
He didn't clarify. Just reached up—slowly—fingers brushing her cheek. She didn't stop him, ddn't flinch, but she did tilt, just slightly, into the touch like she didn't even realize she was doing it.
"The moon," he said, voice casual. "It's beautiful tonight, isn't it?"
His hand came away streaked with her blood. His own blood had smeared across her skin. Seijiro sighed, like it didn't matter.
Kaoru's brows drew together in confusion, looking down at him as if he was cursed. "There's no moon in here, idiot—" She stopped. "Oh," she said, too quietly. She opened her mouth, closed it. Her eyes flicked to his. To his ruined grey eye, the one that no longer glowed, then to his good one still ice-blue. Her expression softened, small. "Yeah. It is beautiful."
For a heartbeat, they were still. Kaoru didn't move. Didn't blink.
Which made her very, very easy to elbow in the sternum. Hard. Cursed energy bursting outward.
"Ugh—!"
Kaoru choked—wind knocked from her lungs—and flew backward with a yelp,crashing into the water like a stone from a catapult. Spray erupted skyward. She tumbled once, twice, then surfaced sputtering, furious.
Seijiro's grin turned impish. "You care too much, Kaoru!" he called out, already on his feet, already launching himself toward her with a burst of Blue propulsion that cracked the water into ripples.
Kaoru wiped her mouth with the back of her hand, blood slick across her lips, hair half-unraveled, and glared absolute murder. "Oh, I'm going to kill you," she hissed, lifting her blade as he approached at inhuman speed.
"Promises, promises!" He came down like a thunderbolt, fist glowing, Blue warping around his knuckles.
And Kaoru—
—vanished.
She sank straight into her shadow and the punch struck empty lake, vaporizing water in a violent boom. A geyser of mist exploded skyward. Seijiro landed, spinning, eyes scanning the haze.
And that's when the lightning hit him.
Direct. Unforgiving. Wild. A blinding arc carved across his back and he was thrown sideways in a convulsion of static cursed energy. He tumbled once, twice, coughed, eyes wide, and turned his head. Standing there in the mist: another smaller shadow. Younger. Narrower frame. A boy with spiked hair and lightning that danced along a familiar staff.
"Oh, perfect," Seijiro groaned, staggering upright with a hand braced to his ribs. "You brought the gremlin."
Shadow-Hajime crouched low like a wild animal, lightning pulsing down his cursed staff, smirk wide and eerily familiar as he darted forward again.
Seijiro sidestepped just in time as a bolt of lightning sliced the air beside him. The charge grazed his side, searing through cloth and skin. He hissed. "Not the real Hajime. Shikigami. Definitely his attitude, though."
Another bolt ripped the sky in two. He threw his hand up, cursed energy flaring. Falling Blossom Emotion snapped into place, a flicker of negation that briefly silenced the sure-hit effect before vanishing again.
Across the mirrored lake, Kaoru emerged from the haze, arms crossed. Watching and grinning like a fox. "Hey! He always said he wanted to fight you for real!"
"Not while I'm half-dead!" he shouted, swerving as a second bolt carved the lake between them. Another crash, another burn, another welt smoking across his shoulder.
"Rude!" he howled, spinning out of the way with Blue-powered footwork.
The Shadow-Hajime landed in a crouch, crouched between them like a tiger at rest. Seijiro braced, panting, muscles quivering as his brain was spinning through possibilities faster than his mouth could keep up. So they weren't temporary. These shikigami—no, these shadows—were stored inside her Domain for good, and she could summon them again and again.
A whole army of archived sorcerers waiting inside her Domain.
"Damn," he muttered. "You're building a cursed library."
He wasn't sure if he was impressed or terrified. He blinked, scanning around the water. No Divine Dog. No Shadow-Seijiro.
Suspicious.
Then, movement. Shadow-Hajime lunged again, but this time, Seijiro didn't give him a chance to make contact. Blue ignited midair—he twisted and fired, sending the shadow flying sideways in a burst of kinetic backlash. But before he could follow through—
A flicker.
Kaoru was there again, a blur from the left, katana raised, shoulder trembling from overuse but eyes steady and locked. From the right, another shape materialized from the water. The stance was unmistakable: forward foot light, weight sunk low, leading elbow tucked tight.
The real shadows of her whole life.
"Of course," Seijiro said flatly. "You've got 'Nobu too."
Kaoru's strike came first and he caught it bare-handed. The katana split palm like a knife through wet rice, blood blooming instantly and dripping into the mirrored lake below with a lazy plink but he didn't flinch. He shifted, pivoted on his heel, and used her momentum to his advantage, shifted weight, pivoted his hips, and pulled throwing her off-balance.
She stumbled, just as Seijiro twisted and launched a counter-Red at the incoming Shadow-Harunobu with his good-hand. The shadow melted into mist just before impact.
"She dismissed it," he breathed. That Shadow-Nobu had been seconds from being destroyed. And she saved it.
Smart. But that means...
His eyes snapped back to Kaoru in time to see that her mask had slipped, just enough for him to see it. The hesitation, a flicker of calculation gone wrong. "Aha," he said, delighted. "You flinched." Realization clicked in place.
The grin that pulled across her lips in response was almost proud. And there it was: the confirmation. These shadows—him, 'Nobu, even that damned gremlin Hajime—if one was destroyed… it was permanent. Just like her others Ten Shadows Shikigami.
Seijiro stepped back, straighter, ignoring the blood down his wrist and wiping the blood off his palm on his hakama. Breathing hard. "You can store them all," he thought aloud. "Inside your Domain. Every shadow you've ever taken."
Kaoru recovered with an elegant backstep, not denying it. She gave him a look, half warning, half fond.
"And once they're destroyed," he continued, "they're gone. Just like your Divine Dog. Just like your other summons." He tilted his head. "That's why you're careful. You're scared to mess up." He looked at her then, this time less like an opponent and more like something holy. Like someone impossibly clever and infinitely doomed. "You can't use them outside your Domain, right?" he asked aloud, voice lighter now, teasing even through blood. "Otherwise, I'd have seen these freaks before."
She said nothing, but he could see it. The way her brow twitched. How her eyes dropped for a second too long. "That's it, isn't it?" Seijiro inhaled, gaze flicking upward, admiring the mirrored twilight dome overhead. "Kami," he exhaled. "What a beautiful Domain."
Terrifying. Flawed. Human. Kaoru glared death at him, and he could feel it across the water like a slap but he only grinned wider. Oh. Now I've done it.
"Don't look at me like that," he said, cocking his head. "You knew I'd figure it out. You wanted me to."
She rolled her eyes. Rotated her katana with one hand like it weighed nothing, lazily, far too casual for how pissed she clearly was. "It's not like I can't use more than one at the same time. But it's lot of focus and coordination to control all of this," she muttered, almost petulant, gesturing vaguely at the Domain around them, the water, the dome, every shadow she ever stole floating on the surface. Her fingers paused and a small private smile formed on her lips. "Too bad I won't have time to perfect it now," she admitted quietly.
The silence that followed cracked something open in his chest. But before he could reply, she smirked.
"Well. I've always wanted to test this."
