Chapter Text
Episode 1
Shido Itsuka jumped back, boots scraping against broken concrete as a red spear tore through the space where his chest had been a half-second earlier.
He landed hard, one knee dropping to the ground before he caught himself. The impact traveled up through his leg and settled in his already aching joints. The red-and-black armor was scuffed from their last several clashes — a long scratch running across the left pauldron, the edge still faintly warm from the friction of the last near-miss.
He straightened, scanning the battlefield.
Broken buildings stretched in every direction. Dust hung in the air in slow drifting columns, catching what little light filtered through the overcast sky above. The ground was uneven — cracked in long jagged lines, chunks of concrete displaced and upended like something had pushed through from beneath.
A voice arrived in his head. Dry. Unhurried.
"You had a clear opening earlier. And you barely dodged that spear." A brief pause. "If it were the real Cu Chulainn, you'd be dead."
"You know I'm doing my best, Archer " Shido muttered through his teeth.
A second voice followed immediately — flat, carrying none of Archer's sardonic edge.
"Contractor. Look above you."
Shido's eyes snapped upward.
The Echo was already descending, red spear raised overhead, the full weight of his momentum committed to the strike. The tip caught a sliver of light as it fell — a brief crimson flash before it blurred into motion.
His hands came up on instinct, magic circuits igniting along his arms in a brief surge of heat that ran from his shoulders down to his palms.
Two swords materialized in his grip — one black, one white, mirror images curving toward each other like they were designed to find one another.
The spear came down.
Kanshou caught it from the left, sweeping the shaft aside with a sharp screech of metal on metal. The force traveled up Shido's arms and settled in his shoulders. Bakuya followed without pause — a diagonal slash aimed at the Echo's exposed flank.
The Echo twisted away, landing a few meters back, boots grinding against the rubble, spear already repositioning.
The fight continued.
Close. Grinding. No ground gained by either side, just seconds bought one exchange at a time. Every time Kanshou shattered under the Echo's force — and it shattered often, the black sword taking the worst of each block — Shido felt the drain of replacing it. Another projection. Another pull on reserves that were already running well below comfortable.
His knees had started to ache in a deep, settled way that meant they'd been working too long. His arms responded a fraction slower with each block, the swords feeling less like extensions of his body and more like dead weight he was forcing into position through effort alone.
"Contractor. Your reserves are running low."
"Yeah," Shido managed between breaths, ducking under a wide horizontal sweep. "you dont need to tell me that i feel it."
"His reserves mirror yours"
Shido frowned, not breaking his guard. "What does that mean, Archer? Stop being cryptic — I'm fighting for my life here."
"Use your brain." Archer's tone carried the faint edge of someone who had chosen patience over exasperation and was finding that choice increasingly difficult. "Bait him into using his Noble Phantasm — or did I need to spell that out?"
Shido sidestepped a thrust that would have taken him through the shoulder, concrete fragmenting beside his boot where the spear tip caught the ground instead.
"his Noble Phantasm?"
"Affirmative, Contractor." Alaya's voice, clean and level. "If the Echo is forced to expend energy on a Noble Phantasm activation prematurely, the output drop will create a viable opening."
Shido exhaled — one controlled breath, pushing the fatigue back far enough to think clearly.
*Here goes nothing.*
He disengaged — a sharp backward leap that carried him across the ruined terrain in a single burst of Reinforcement through his legs. He landed atop the remains of a collapsed building, broken rebar jutting out around him at uneven angles, the surface beneath his boots shifting slightly under the weight before settling.
The Echo's red silhouette tracked him from below.
The spear lowered slowly.
Both of them breathing. Both of them waiting.
Shido raised Kanshou and Bakuya and steadied his stance against the uneven ground.
The Echo turned to face him fully.
"Bet you can't get me up here."
The words left him before he'd fully thought them through — which was becoming a pattern.
The Echo's expression was difficult to read beneath the distortion of its form. But something in its posture shifted. The angle of the spear changed. The air around it tightened.
"I think you made him mad, kid."
Archer's tone carried something that might have been amusement if it had tried a little harder.
"Yeah," Shido muttered. "Hopefully mad enough."
The Echo raised its spear.
Red light gathered around the tip — not the sharp flare of a normal charge, but something slower. Deeper. Building from within rather than burning outward. The air around the weapon began to distort, bending slightly inward toward the point like space itself was being drawn into it.
Shido's throat tightened.
"What exactly does his Noble Phantasm do?"
"Oh, right." A pause that lasted exactly long enough to be uncomfortable. "I'd prepare if I were you."
"Gae Bolg." Alaya's voice arrived without preamble. "That is the name of his Noble Phantasm, Contractor. It operates by reversing the roles of cause and effect — the strike is guaranteed to connect before it is thrown."
Shido stared.
"…What?"
"In simpler terms," Alaya continued, "he always hits whatever he aims for." A brief pause. "He typically aims for the heart."
"Eh?! You should've told me before I made him angry!"
"Relax." Archer's voice, dry as ever. "This is an Echo. It doesn't carry the full output of the original. You'll live." Another pause. "Barely. You just need to block it."
"How am I supposed to block something that already hit me before it's even thrown?!"
The red light around the spear intensified, the glow spreading up the shaft and bleeding into the surrounding air in uneven pulses. The Echo pulled back its arm.
"Gae Bolg—!"
The spear shot forward.
Shido's arm came up.
"Rho Aias!!"
The shield burst into existence — seven layered barriers unfolding in sequence, each one like a petal of crystallized light locking into place, the full formation assembling in a single desperate heartbeat.
The spear hit.
The first layer shattered.
The impact traveled through the structure and into Shido's body simultaneously — a sharp, radiating pain that spread from his chest outward like something had struck him directly despite the barrier between them. His knees buckled.
The second layer broke.
"Ahhh—!" He ground his teeth, forcing his legs straight. "Not yet—"
The third layer cracked down the center.
The fourth followed immediately after.
Each break sent another wave of reflected damage through him — his arms burning, his vision blurring at the edges, the ground beneath his boots feeling less certain with every passing second.
Then —
Silence.
The pressure vanished.
Dust swirled across the battlefield in slow, directionless clouds. Through the haze, the Echo's silhouette stood still — spear arm lowered, posture changed. The red light around it had gone out completely.
Its mana reserves were spent.
It began to turn away.
Then it stopped.
Then it looked back.
"Now, Shido!"
He was already moving.
Battered, barely upright, one arm hanging lower than it should — Shido crossed the distance with everything Reinforcement had left to give. The white sword in his grip was cracked down the middle, the projection failing at the edges.
It didn't matter.
The Echo tried to move. Exhaustion held it in place.
One swift slash across the neck.
It was over.
Shido skidded to a stop, turning back as the Echo's form dissolved — blue light spreading outward from the point of impact, the silhouette losing coherence piece by piece. The red spear clattered to the ground, solid for one final moment, then followed its owner into nothing.
Left behind on the broken concrete —
A single card.
Shido's legs gave out.
He sat down hard, gasping, both hands braced against the rubble behind him.
"…That was close."
"Not bad." Archer's voice arrived after a considered pause. "Seven out of ten."
Shido's head snapped up.
"Seven?! I deserve at least an eight, Archer!"
No response came. Which was somehow worse than a disagreement.
Alaya stepped forward from the edge of the battlefield, crossing the debris-strewn ground without adjusting her pace for any of it. She crouched beside the card, picked it up, and held it at eye level — her gaze moving across its surface in the particular way that meant she was processing rather than looking.
A moment passed.
She glanced at Shido.
"Echo neutralized, Contractor." She tucked the card away with the same motion she would use to file a document. "Shall we celebrate at our usual spot?"
Shido stared at her for a moment.
Then he sighed — the long, boneless kind that came from someone who had already accepted the answer before asking the question.
"Do I even have a choice?"
Shido was covered in bandages, most of them hidden beneath his uniform — visible only where the collar shifted or his sleeve rode up, quiet reminders of the last hour that he was already trying not to think about.
They were sitting in one of the better cafés in Tengu City. Considerably better than anywhere Shido would have chosen on his own. The kind of place where the menu didn't list prices because the clientele wasn't supposed to need to check.
He was here because of the girl sitting across from him.
Alaya — the Spirit of Humanity's Will to Survive, a being of effectively limitless conceptual authority — was eating strawberry shortcake with the focused, unhurried dedication of a child who had discovered something worth protecting. Her usual flat affect had been replaced by something that couldn't quite be called an expression but was definitely pointed entirely at the dessert in front of her.
Shido's eye twitched as his gaze dropped to the bill sitting at the edge of the table.
"That bill is already at 10,000 yen…"
He let his forehead fall against the table with a dull thud.
"That is not my issue, Contractor."
"At least try to understand the problem." His voice came out muffled against the tablecloth. "We come here every time I defeat an Echo."
"Yes." A brief pause — the sound of a fork against a plate. "To celebrate your victory. Is that not a normal human custom?"
Shido lifted his head.
"If this is to celebrate my victory, then why am I spending 10,000 yen on your shortcakes? You've already had four." He gestured at his own side of the table. "I got a glass of water."
Alaya considered this with the same expression she used to analyze Class Cards.
"Apologies. It did not occur to me that this would present a financial difficulty, Contractor." Another forkful of cake. "I have no funds to contribute. I am, as you would say — broke as fuck."
Shido stared at her.
The café continued its quiet, well-mannered ambience around them.
"However." Alaya set her fork down with precise care. "To repay you — from data I have gathered, giving one's body for another's carnal pleasure has functioned as a form of payment across multiple periods of human history. I am willing to provide you with carnal rele—"
Shido moved faster than he had during the entire fight with the Echo.
A spoon appeared in his hand. A large portion of shortcake followed it directly into Alaya's mouth before she could finish the sentence.
Alaya blinked, momentarily occupied with chewing.
The café went quiet by several degrees.
The elderly woman at the next table set her teacup down with a sharp little clink.
"Kids these days," she muttered to her companion, shaking her head slowly. "No shame. None at all."
Her companion — a woman of similar age — leaned in slightly, voice dropping to the particular volume that was meant to carry.
"And look at him. Dragging a poor girl somewhere expensive and then acting like that. No good playboy, that one."
"Using women like they're nothing," the first one agreed, clicking her tongue. "Disgraceful."
Two university students near the window had their hands pressed over their mouths, shoulders shaking.
The older gentleman by the counter had picked up his newspaper again but was very clearly not reading it.
Shido could feel every single pair of eyes in the room.
His face was the color of the strawberries on Alaya's plate.
"Just," he said, with the quiet desperation of a man watching his reputation dissolve in real time, "forget about it. And eat your shortcake."
Alaya nodded, expression returning to its usual neutral register, and continued eating as if the entire café had not just collectively decided Shido was a degenerate.
Because as far as she was concerned, nothing unusual had happened.
Shido picked up his glass of water and took a long, slow sip.
After a moment, the conversation shifted.
"So… about the Echoes?"
Alaya's fork paused halfway to her mouth.
"What about them, Contractor?"
"Where exactly do they come from?"
She set the fork down, the shortcake momentarily forgotten — which, in Shido's experience, meant she was actually thinking rather than just processing.
"Echoes are fragments of Heroic Spirits brought into this world by some unknown force." Her eyes moved to a point slightly past his shoulder, the way they did when she was pulling from stored information rather than active observation. "Prior to each manifestation, a mana surge is detected in the surrounding area. The cause remains unidentified."
Shido rested his chin on his hand, turning that over.
*Surge of mana before an appearance.*
"In other words…" He straightened slightly. "Are Echoes related to Spacequakes? Every one we've fought appeared after a recent Spacequake in the area."
Alaya looked at him.
For a brief moment, something in her expression shifted — not surprise exactly. More like the particular quality of attention given to something that had connected two data points she hadn't fully aligned yet.
"That is my current theory, yes."
She picked her fork back up.
Shido stared at the table, thinking.
Neither of them had an answer beyond that. The silence settled comfortably between them — the kind that came from two people sitting with an open question rather than rushing to close it.
The bell above the café entrance chimed.
Tonomachi Hiroto stepped inside, still reading the laminated menu card he'd picked up from the display stand by the door, already mentally committed to the deluxe set.
"Yes, um — can I have the deluxe meal, and maybe a—"
He looked up.
Froze.
Across the café, sitting at a table by the window, was a face he recognized immediately.
Shido Itsuka.
Tonomachi's mouth stayed open for a moment without producing any further words.
Shido was sitting across from a girl in a Raizen High uniform — younger, probably a lower classman, silver hair, the kind of quiet composure that made you feel slightly underdressed just looking at her. And Shido — his friend Shido, who had never once mentioned having a girlfriend — was spoon-feeding her cake with an air of complete domestic familiarity.
"...When did this happen?"
The question left him at a volume nobody else in the café heard.
Tonomachi's hand moved to his phone before the thought had fully formed.
The shutter sound was very small. He was very careful about it.
He took one photo. Then, after a moment's consideration, a second one from a slightly better angle.
He quietly canceled his order.
He absolutely was not going to be the one to interrupt this. Whatever was happening at that table, it had been going on long enough that Shido clearly hadn't felt the need to mention it — which meant it was either very new or very serious, and either way Tonomachi wanted details.
He slipped back out through the door.
He took one last look through the window at his friend, who was now staring at the bill with the expression of a man reconsidering his life choices.
*Nice one, Shido.*
"I'm telling you, that girl is not my girlfriend!"
Shido pressed both palms flat against his desk as Tonomachi leaned over it from the other side, wearing the expression of someone who had already decided the truth and was simply waiting for the confession to catch up.
"Come on, man. You don't have to hide it from me — I'm your buddy." Tonomachi shook his head slowly, the gesture of someone deeply impressed. "But seriously… I never thought you'd go for someone that young. Don't tell me you're eyeing your sister too while you're at it."
"What the hell are you even talking about?!" Shido's voice jumped half an octave. "I told you she's just a friend! And what does Kotori have to do with anything — she's my younger sister!"
"Adoptive sister." Tonomachi raised both hands. "Look, man. I'm not here to judge anyone's taste. You don't have to hide it from me."
"And I'm telling you — that is not what's happening!"
Tonomachi opened his mouth to continue.
Then went quiet.
His eyes moved to somewhere behind Shido's left shoulder.
Shido frowned.
Footsteps approached — measured, unhurried, each one placed with the kind of precision that didn't come from thinking about it.
"Shido Itsuka."
He turned.
A girl stood beside his desk. White hair. An expression that gave away nothing — not cold exactly, more like the concept of temperature simply hadn't applied itself to her face yet. She held her phone out toward him, screen facing forward.
On it — the photo from the café. Alaya with the shortcake. Shido with the spoon.
"Is this your girlfriend?" Her eyes stayed on him, level and unblinking. "Answer honestly."
Shido blinked.
"Uh… no. She's just a friend."
A brief pause.
"I see."
The girl lowered her phone, turned, and sat down at the nearest available desk with the same quiet efficiency she'd arrived with. No follow-up. No further questions. As if the answer had been filed and the matter was closed.
Shido stared at the empty space she'd been standing in.
Then turned back to Tonomachi.
Tonomachi was looking at him with an expression that sat somewhere between impressed and deeply concerned.
"Dude…" He kept his voice low. "How do you know Tobiichi?"
"Who?"
"The white-haired girl who just walked up to your desk and interrogated you." Tonomachi paused. "Are you living under a rock?"
"Should I know her?"
"That's Origami Tobiichi." Tonomachi said the name like it should have solved something. "Highest academic scores in the year. Top five on the most desirable girlfriend list — three years running."
Shido glanced back toward where she'd sat.
"I'm less concerned about that and more concerned about how she got that photo in the first place," he said slowly. "That's a little creepy."
Tonomachi's expression shifted into something slightly sheepish.
"Ah. That was me."
Shido turned back around.
"I posted it online. For support. You know — showing love for my bro."
"Why." Shido's voice came out very flat. "Would you do that."
"I wanted—"
"Alright, everyone — settle down!"
The door slid open. Tamae Okamine stepped inside, clutching her attendance folder to her chest, already scanning the room with the optimistic energy of someone who believed today would go smoothly.
"Take your seats, please! Homeroom will start shortly!"
Chairs scraped. Bags rustled. The room shifted back into the shape of a classroom.
Shido dropped into his seat, shooting Tonomachi one final look that communicated everything he hadn't finished saying.
Tonomachi mouthed *sorry.*
He did not look sorry.
The room settled.
And then — the alarms rang.
"Alright, everybody — don't panic! Follow the evacuation procedure and get down to the shelter!"
Tamae's voice carried down the hallway with considerably more urgency than the students receiving it seemed to feel was warranted. They filed out in a loose, unhurried stream — conversations continuing uninterrupted, someone near the back laughing at something on their phone. The alarm blaring overhead might as well have been background music.
Shido moved with the crowd, letting himself be carried along for exactly long enough.
Then he wasn't there anymore.
He peeled away from the group at the first corner, slipping through a side door and into an empty corridor. His footsteps echoed sharply against the tile as he broke into a run, the sounds of the evacuation fading behind him.
It hadn't even been a full day since Cu Chulainn. His body hadn't forgotten — a dull ache lived in his ribs with every stride, his left shoulder protesting each time his arm swung forward. The bandages beneath his uniform were doing their best.
Duty, apparently, did not care.
He reached into his pocket as he ran, fingers closing around the card marked with the Archer class. Its surface was warm against his palm.
He extended his arm forward.
"Install!"
The card ignited. A magic circle bloomed in the corridor ahead of him — geometric, precise, rotating through its sequence in the span of a heartbeat. Shido ran through it without slowing.
His school uniform dissolved.
Red and black armor replaced it, settling into place around him as prana surged through his body in a single clean wave. His stride lengthened. The ache in his ribs didn't disappear — but it moved somewhere further away, behind the momentum.
He hit the school gates at full speed and burst through them into empty streets.
Tengu City had become a ghost town. The roads were bare, every storefront shuttered, the distant sound of shelter announcements playing on a loop from speakers nobody was left to hear. The sky above had taken on the particular quality it got before a Spacequake — heavy, slightly wrong, like the air pressure had made a decision without consulting anyone.
Archer's voice arrived in his head.
*Here we go again.* A dry pause. *Not even a full day, and you're already being thrown back to the wolves. Have your wounds from yesterday even healed?*
"No," Shido said, breath steady despite the pace. "I'm pretty sure a few bones are still broken."
*Naturally.*
Alaya stood atop a nearby building, the wind pulling at the trailing edges of her dark robes as she looked down at the Spacequake crater below.
What she saw was unexpected.
Two figures clashed violently within the impact zone, the sound of steel meeting steel reaching her from below in sharp, irregular bursts. The crater's edges were already scored with impact lines — whatever had been happening down there had started before she arrived.
"Analysis initiated. Two combatants detected. Identifying—"
A pause that lasted a fraction longer than her analyses usually did.
"Error. Unknown combatant detected. Initiating secondary analytics."
One of the figures was a girl clad in purple armor, a broadsword moving in her grip with the weight of something that had been made for her specifically. The energy radiating from her didn't match anything in Alaya's existing catalog — it resembled the signature of a Heroic Spirit, but the resemblance wasn't complete. The data kept returning inconsistencies wherever she pressed it.
She was not a Heroic Spirit.
The second combatant required no secondary analytics.
An Echo. Its holy sword caught the low light of the overcast sky as it swung — gleaming, unmistakable, the kind of weapon that carried its own identification simply by existing.
Only one figure in recorded human history had ever wielded it.
"Arturia Pendragon. Saber-class."
But something was wrong.
"Shirou—!"
The Echo's voice tore through the crater — distorted, fragmented, the sound of something that shouldn't have been capable of language producing it anyway. The name came out desperate. Repeated. Like a signal that had been trying to transmit for a very long time and had only just found the frequency.
"Shirou—!"
Alaya's processing stilled for a fraction of a second.
"Anomaly detected."
Echoes were fragments — remnants stripped of true intelligence, capable of combat instinct and nothing more complex. Speech was rare. Remembering specific names was rarer still. Whatever remained in this Echo, it had held onto that name across whatever distance separated it from the original.
"Scanning 'Shirou' within Arthurian mythos database—"
A pause.
"Zero results found."
Strange.
She opened the mental channel immediately.
"Contractor."
Shido's voice came back, slightly breathless from the pace. "Yeah. I'm heading toward the Spacequake zone now. What is it?"
"I have located the Echo." She transmitted the coordinates without elaboration. "Please arrive as soon as possible."
"Can you tell me about the Echo?"
"The Echo is currently engaged in combat with an unknown variable." A brief pause. "I will explain further upon your arrival. The Echo's confirmed identity is Arturia Pendragon. Saber-class."
A beat of silence on the other end.
Then, quieter — from somewhere that wasn't Shido:
*...Arturia.*
Shido leapt from rooftop to rooftop, reinforced legs propelling him forward in long, clean arcs. The streets below were empty — rooftops were faster, and right now faster was the only thing that mattered.
But something felt off.
Archer had gone completely silent the moment Alaya named the Echo. Not the usual silence of someone choosing not to comment — something heavier than that. The kind that took up space.
"Archer?" Shido landed, pushed off again without breaking pace. "You okay? You usually would've said something annoying by now."
A pause that stretched longer than it should have.
*…Of all people.* A quiet exhale. *Why did it have to be her?*
"You know the Echo?"
*I knew the real one.*
Shido's next landing was softer than the others — deliberate, giving the moment room.
"Do you want to talk about it?"
Another pause. This one felt different from Archer's usual reluctance — less like someone deciding whether to speak and more like someone deciding where to start.
*Her name was Arturia Pendragon.* His voice came out measured, each word placed carefully. *You might know her as King Arthur.*
Shido nearly broke his stride.
"Wait — King Arthur? The guy with Excalibur?" He pushed off the next ledge. "Then why is she a girl?"
*It's complicated.* A brief pause. *She was born a woman and lived as a man to become king. The legend didn't preserve that detail.*
"Then how do you know him---i mean her?" Shido landed on a wider rooftop and kept moving. "Don't tell me you were a Round Table knight or something."
*No.* Something in Archer's tone shifted — quieter, more careful. *Do you remember what I told you about the Holy Grail War?*
"Seven Servants, seven Masters. Everyone fought over something called the Holy Grail."
*I was one of those Masters.* A pause. *Arturia was my Servant.*
Shido nearly missed his next jump entirely, boot catching the edge of the rooftop before he corrected.
*We were close.* The words came out slower than Archer's usual delivery. *Closer than we should have allowed ourselves to be.*
"Wait—" Shido landed, processing. "King Arthur. Your Servant. And that close."
*Is that so hard to believe?* A dry note returned to his voice, brief and familiar — the tone Archer used when he wanted to change the subject without appearing to. *I was quite dashing at your age. Regardless — when the war ended, she couldn't remain. But we made a promise to find each other again someday.* A pause. *I've been looking ever since.*
Shido said nothing for a moment.
The rooftops passed beneath him. The Spacequake zone was getting closer — he could feel the shift in the air, the particular wrongness that preceded an Echo's presence.
"…I'm having doubts about fighting her," he said quietly.
*Don't.*
Archer's voice came back without hesitation — not harsh, but firm in a way that didn't leave room.
*That Echo is not Arturia. It carries her image and her weapon, but it is not her.* A brief pause. *If the real Arturia were here — she would want that Echo destroyed. She would never allow something wearing her face to endanger innocent people. That was who she was.*
His voice hardened slightly on the last words. Not with anger. With certainty.
*She would want this.*
"…Okay," Shido said.
He didn't say anything else. Neither did Archer.
The weight of it traveled with him the rest of the way — quiet, settled, belonging to both of them equally.
A thunderous roar split the sky without warning.
Shido's body moved before his mind caught up — he dropped low behind a chunk of collapsed wall, back pressed flat against the crumbling concrete as the sound tore overhead like something massive burning through the upper air.
He held still. Listened.
Then, carefully, he tilted his head up and looked.
Above the crater, cutting through the haze of drifting dust and displaced air, several figures carved clean lines across the sky. They moved in tight formation — disciplined, coordinated, the kind of movement that came from drilling the same pattern until the body stopped needing to think about it.
Shido's eyes narrowed.
Girls.
Clad in mechanized armor that caught the light in sharp, angular flashes. The plating was sleek and purposeful — and in places, unsettlingly revealing. Heavy rifles rested in their hands, barrels angled toward the ground below with the patient readiness of weapons that hadn't decided not to fire yet.
"What are those girls doing here?" he muttered, pressing lower against the rubble. "Shouldn't everyone be evacuated?"
He focused, activating Archer's skill.
Hawk Eye.
The distance collapsed — details sharpening out of the haze like a lens snapping into place. The precise cut of the armor. The faint shimmer of contained energy around each figure's frame. The devices mounted at their backs pulsing with regular, controlled output.
"It looks like they're flying using devices on their backs," Archer said.
"What? How?"
"They're generating localized bounded fields around themselves — allowing them to defy gravity." A brief pause, clinical and unhurried. "Impressive, in a crude sort of way."
"Then why are they here?"
Archer didn't answer immediately.
Below them, the battle between the Echo and the girl in purple armor continued — steel against steel, golden light flashing against Sandalphon's edge in violent, overlapping bursts. The sound of it carried even from this distance. Whatever those armored figures were, they had arrived at exactly the wrong moment.
"I don't know," Archer said at last. "But avoid being seen."
Shido tightened his grip on the edge of the rubble.
Things were getting complicated
She didn't know why the woman in front of her had attacked.
One moment she had arrived — the world snapping into existence around her the way it always did, disorienting and immediate, no warning and no preparation. The next, steel was already moving toward her life.
She raised Sandalphon on pure instinct.
The broad blade caught the strike with a bone-deep impact that ran up both arms, the purple energy along its edge flaring violently under the force. Her boots scraped backward across broken ground, heels digging in as she absorbed the momentum through her legs.
"Who are you?!" The words tore out of her before she could shape them properly, raw with anger and something underneath it that wasn't quite fear but wasn't far from it either. "Why are you attacking me?! Are you with the Mecha-Mecha Squad?! Did they send you to kill me?!"
Her opponent said nothing.
Then — one word.
"Shirou."
It didn't make sense. The voice that carried it was wrong — distorted at the edges, layered over itself, like sound passing through something that wasn't properly air. It belonged to something that shouldn't have been able to form words at all.
"What… are you talking about?!"
No answer came.
The woman pressed forward without hesitation, and the Princess felt it immediately — there was no strategy in the attack, no reading of distance or timing. Just force. Absolute, relentless, overwhelming force that didn't slow and didn't adjust and didn't care what was in front of it.
Golden light erupted from the holy sword in a wide, sweeping arc.
The Princess threw herself sideways. The crescent of light tore through the space where her head had been a half-second earlier, the displaced air hitting her cheek like a struck bell, sharp and hot.
She landed hard, one knee catching broken stone, and came back up immediately — Sandalphon rising between them as the next strike descended.
The clash sent sparks cascading in every direction, purple and gold bleeding together in violent flashes that lit the crater floor.
"Shirou—!!"
The name again. Torn from somewhere that sounded like it hurt.
The Princess gritted her teeth and pushed back.
High above the crater, Origami held formation.
The squad moved in practiced silence — two members flanking her on either side, thrusters making minute adjustments to hold spacing against the shifting air currents rising from below. Ahead of them, Captain Kusakabe maintained her position at the formation's head, scanning the battlefield with the calm, methodical attention of someone who had done this enough times that the tension had stopped showing on her face.
"Captain, I'm detecting Princess's spirit energy."
"Good." Kusakabe's voice carried across the comms without urgency. "All units, prepare to intercept."
"Yes, ma'am!"
Origami's eyes moved across the readouts scrolling at the edge of her visor.
Something was wrong with the numbers.
"…That's strange."
"What is it, Tobiichi?"
"I'm detecting another signal from the same area." Her fingers moved across her console, pulling the reading forward, isolating it. The signature kept shifting every time she tried to pin it down — present, then wrong, then present again in a slightly different configuration. "It's similar to a Spirit — but it doesn't match anything in our database."
The formation reached the crater's edge a moment later.
Below them, the battlefield resolved into something that didn't fit any briefing she had been given. Princess was there — purple armor, Sandalphon in hand, locked in close combat with a second figure. The second figure moved with the fluid, overwhelming aggression of something that wasn't fighting to win so much as to destroy. Golden light flared from a holy sword that had no business existing in anything Ratatoskr or the AST had ever catalogued.
Origami's expression stayed flat.
"Captain," she said carefully. "What are our orders?"
Kusakabe was quiet for exactly one second.
"Two targets." Her jaw tightened slightly. "On my signal — open fire on both."
The squad spread outward, thrusters carrying them into a wide encircling arc above the two combatants. Rifles rose. Targeting systems aligned.
Below, neither figure looked up.
"Fire."
The sky lit up.
Beams of blue-white energy rained downward in overlapping lines, converging on the crater floor with the coordinated precision of a unit that had practiced this until it stopped feeling like destruction and started feeling like procedure.
Origami watched the impacts register on her targeting display.
Princess — shield up, readings stable, energy dispersing cleanly against the barrier.
The second figure —
Her eyes narrowed.
The readings didn't change.
Not even slightly.
Every beam that struck the golden-bladed woman simply vanished from the display. No deflection. No absorption spike. No damage output whatsoever.
Origami looked up from her display and confirmed it with her own eyes.
The woman was still standing. Completely untouched.
She filed it without expression and kept watching.
Damn it — the Mecha-Mecha Squad.
The beams came from everywhere at once, filling the crater with overlapping lines of blue-white that left no clean angle to move through.
Princess reacted instantly, her left hand snapping up. A shimmering purple forcefield bloomed around her, dense and immediate. The energy crackled against its surface in sharp bursts before dispersing harmlessly into the air.
She held her ground.
Across the crater, the golden-bladed woman stood directly in the barrage.
The full volley struck her without interruption — beam after beam, overlapping, sustained. The light washed over her frame and vanished. When the last beam faded, she was exactly where she had been standing. Unmarked. The golden armor caught the light the same way it had before the volley started.
Princess stared.
Then the woman raised her sword.
The holy blade ignited, light building along its edge in a sharp ascending whine. It released — blades of concentrated light erupting skyward in a wide sweeping arc, tearing upward toward the formation above.
Scatter commands burst through the AST comms. Thrusters screamed as the squad broke in every direction.
"Shirou!!"
The scream tore through the crater.
That attack was enough to make the Mecha-Mecha Squad retreat temporarily.
At least now Princess knew one thing.
The woman wasn't with them.
The golden swordswoman turned back toward her, eyes burning with fixation.
Princess tightened her grip on Sandalphon, lowering into a ready stance.
There was no reasoning with the woman in front of her.
Only battle.
---
From atop a collapsed structure at the crater's edge, Alaya observed the scene unfold below.
"Another unknown variable has interfered."
Her eyes moved across the battlefield with quiet precision. A group of women in peculiar armor had entered the area, attacking both the anomaly and the Echo without apparent distinction between them. Strange mana signatures radiated from the devices mounted at their backs and heads — not from magic circuits. Not from any internal structure she recognized.
They were using bounded fields without conventional magecraft.
The air around their equipment carried a faint, artificial resonance — organized, functional, entirely human in construction.
"Curious."
Then she detected her Contractor.
Shido was approaching rapidly from the north edge of the ruins, moving rooftop to rooftop, closing the distance faster than any unaugmented human could manage. He wasn't slowing down.
Alaya considered intervening herself.
The thought surfaced, was examined, and dismissed in the same motion.
An unnecessary risk — for now.
Her hand opened at her side. A card materialized into her palm, its surface catching no light — flat, deliberate, marked with the Archer class symbol.
She closed her fingers around it.
And continued to watch.
Shido landed on the crater rim and stopped.
The scale of it hit him before anything else did. The ground below had been carved open in a wide, uneven bowl — concrete and asphalt peeled back in layers, the earth beneath exposed and scorched, debris scattered outward from the center in every direction. Whatever had happened here hadn't been small.
"That's… huge." The words came out quieter than intended. "What could've caused this?"
"Many things," Archer said. "A meteor. A nuke. But most likely — a Noble Phantasm being released."
Shido stared down into it. "A Noble Phantasm can cause this much damage?"
"Some can cause far more, depending on their nature." Archer's tone stayed level. "I've seen one capable of leveling an entire city. I've witnessed another with the potential to destroy the planet if fully unleashed."
Shido swallowed.
He looked down into the crater.
Alaya was nowhere in sight — but that didn't matter. The sooner the Echo was dealt with, the better.
He dropped over the edge.
Reinforcement surged through his legs as he fell, prana tightening into his muscles and bones, bracing for impact. The crater floor rushed up to meet him. He hit with a heavy thud that sent a shockwave of dust rippling outward from his boots, the force rattling up through his knees and spine before his body absorbed it.
He straightened.
And stopped.
Archer went silent.
Completely. Instantly. The steady, dry presence that had been running commentary since the rooftops simply — stopped. No sarcasm. No assessment. Nothing. The mental space where his voice usually lived went still in a way Shido had never felt before.
Shido's eyes had already found the source.
The Echo stood at the far end of the crater, holy sword raised high above a girl in purple armor lying motionless on the broken ground. Golden light pulsed along the blade's edge, building toward release. The girl's weapon had skidded out of reach. She wasn't moving.
The Echo's face was wrong. Eyes fixed. Expression locked into something beyond recognition.
Shido didn't wait for Archer to say anything.
He moved.
"Be prepared for anything, kid."
Archer's voice returned — quieter than before. The dry edge stripped out of it, leaving something underneath that didn't have a name yet.
"This might not be the real Arturia. But if it's anything like the one I knew…"
A pause.
"…this'll be a worse fight than yesterday."
Shido was already running, twin blades forming in his hands as prana surged through the projection — Kanshou and Bakuya solidifying black and white, mirror images curving toward each other.
"You're not exactly inspiring confidence, Archer."
No response came.
He closed the distance in seconds and drove both blades upward into the descending sword's path.
The impact rang out across the crater — metal against metal, the force of it rattling up both his arms and locking his feet into the broken ground beneath him.
---
Her foot slipped.
One moment Princess had her footing — the next the broken stone shifted beneath her boot and took it with it. She crashed to the ground hard, the impact driving the air from her lungs, Sandalphon skidding from her fingers and spinning across the crater floor out of reach.
She tried to push herself up.
Her arms didn't answer fast enough.
The golden blade rose above her.
Princess shut her eyes.
Then —
Clang.
The sound rang out sharp and immediate — close enough that she felt the displaced air across her face.
She opened her eyes.
A boy in red and black armor stood between her and the Echo, both swords braced above his head, the golden blade pressing down against them. The muscles in his arms shook with the effort of holding the position. His boots had carved shallow furrows into the ground beneath him.
He was barely holding.
"You need to get up and find somewhere safe!" he said through his teeth, voice tight with effort.
"Who are you?!" Princess pushed herself upright, eyes moving between him and the Echo. "I don't need your help!"
"Just run!" He didn't look at her — his eyes stayed locked on the blade above him, tracking every shift in pressure. "You can't win against this thing — leave it to me and save yourself!"
She hesitated.
Her eyes moved to the sky above the crater rim.
The Mecha-Mecha Squad was regrouping. She could feel it — the distant hum of their devices, the formation pulling back into shape. If they returned while she was still here, still without Sandalphon in hand —
She reached down and closed her fingers around the hilt.
"I'll see you again, boy in red." She straightened, meeting the back of his head for a moment. "Then we'll settle this."
She vanished in a burst of purple light.
Shido exhaled shakily, the tension bleeding out of his shoulders all at once as the sound of the girls departure faded behind him.
The crater settled into an uneasy quiet.
Dust drifted across the broken ground. Somewhere above the rim, the distant hum of the AST's thrusters was pulling back — regrouping, buying distance. For now, they were alone.
"You know," Archer said, "you could've used that moment to set up a shot. You are an Archer, after all." His tone was dry, unhurried — the voice of someone making a point they already knew wouldn't land. "By the time the Echo finished her, you could've killed it from afar. You didn't even know that girl."
Shido rolled his shoulders, eyes moving back to the Echo. "Yeah… but you know I could never do that."
"Of course." A beat. "Sentimentality dressed as heroism. How predictable."
Shido clicked his tongue. "Right back at you, Archer."
He pushed off, jumping backward and putting distance between himself and the Echo, boots scraping across broken stone as he landed and steadied. His chest heaved. The air in the crater tasted like scorched metal and ozone, thick enough to notice with every breath.
He kept his eyes on her.
The Echo didn't move.
She stood exactly where she had been, holy sword lowered slightly, golden light still pulsing along its edge in slow, uneven waves. Her head had turned to follow him when he landed.
She was staring at him.
Not at his weapons. Not at his armor.
At his face.
The silence stretched thin between them, pressed flat by the weight of the crater around them, the broken ground, the distant settling of debris.
Then —
"…Shirou?"
Shido went still.
The word came out wrong — layered, distorted, pushed through a voice that wasn't built for it anymore. But underneath the distortion, the shape of it was unmistakable.
A name.
His shoulders tightened. "Who's Shirou?"
He kept his voice low, directing the question inward. "Archer… any idea why she's saying that? You said you knew the real her."
A pause.
Brief. Controlled.
"I know because that was my name."
Shido blinked. He opened his mouth. Closed it again.
"My true identity is Shirou Emiya."
For a moment Shido didn't say anything. He turned the information over once, trying to find somewhere to put it. His eyes stayed on the Echo — on the fixed, burning quality of her attention, still locked entirely on him.
On the name she thought she recognized.
"…Okay." He exhaled slowly. "Should I recognize you from history? Because that name doesn't ring a bell."
"I wasn't a normal Heroic Spirit." Archer's tone stayed even, unhurried. "Like you, I made a contract with Alaya when I was young."
"Wait — you did?"
"Yes. I became what's known as a Counter Guardian. A spirit sent by Alaya to correct human history. In exchange, she gave me power — to fulfill my dream of becoming a hero." A brief pause, no weight placed on it. "And to find my way back to Saber."
Shido stared at the Echo across the broken ground.
The holy sword. The golden armor. The face that kept searching for something it couldn't find.
"…I didn't know that."
The Echo's head tilted — a fractured, birdlike motion, the movement of something trying to reconcile what it was seeing with what it remembered. Her grip on the sword tightened.
Then something broke behind her eyes.
She screamed.
The sound tore through the crater without warning, raw and formless, the brief stillness shattering under it. The golden light along her blade flared violently, the air around her frame warping under the sudden surge of output. Loose debris skittered outward from her feet.
Archer went quiet.
Then — a slow exhale. Low. Stripped of its usual edge, nothing sardonic left in it.
"I don't like seeing her like this."
Shido didn't respond. There was nothing useful to say to that.
A moment passed.
"Can you do me a favor?"
Shido's grip tightened on Kanshou and Bakuya. "What kind of favor?"
"Let me fight her."
"You mean… lend you my body?"
"Yes." Flat. Immediate. "Call it meaningless sentiment — but I want to be the one to end her pain. It's my duty. As her sheath."
Shido held the thought for a moment.
He didn't fully understand that word. Sheath. But the way it had come out — quiet, certain, placed without explanation — made the meaning feel obvious even without a definition attached to it. Like something that had already been decided long before this conversation.
He thought about the risk.
Letting Archer take control wasn't a small thing. If Archer wanted to, he could keep the body. That was a real possibility and Shido knew it.
But he looked at the Echo again.
At the golden sword. The distorted face. Whatever was left of someone Archer had clearly never stopped carrying.
Shido exhaled.
"Fine." He lowered Kanshou slightly, steadying himself. "But you'd better give it back."
"Thank you." The dry edge returned — measured, deliberate. "I'll make sure to return it in one… maybe two pieces."
"Archer—!"
"Relax. I was just joking."
Shido closed his eyes.
The crater held its breath around him.
When he opened them again, something had shifted — not just in his expression but in the quality of his attention. His hair had deepened to a reddish hue, the color bleeding in from the roots outward. His posture changed by degrees — shoulders settling, weight redistributing, the particular stillness of someone who had spent years learning exactly how much space a body needed before a fight started.
His gaze found the Echo across the broken ground.
"I never thought our next meeting would be like this, Saber."
The words came out quiet. Flat in the way of something stated rather than felt.
The Echo stilled.
Just for a moment — a fraction of a second, so brief it almost didn't register. Her sword arm didn't lower. Her stance didn't change. But something shifted behind her eyes, the madness pulling back just far enough to let something else surface.
Recognition.
That voice.
Then it was gone.
The golden light along her blade flared violently and she screamed — formless, raw — and came at him.
Shirou moved instantly.
His eyes flicked to her sword.
"Trace… on."
Magic circuits ignited along his arms in cold blue lines, the familiar surge of prana flooding outward in a single directed wave. A holy sword formed in his grip — rough at the edges compared to the original, built for function rather than perfection — Excalibur, traced.
He raised it.
The first clash rang out across the crater like a struck bell, the impact traveling up both arms and into his shoulders. He absorbed it through his legs, boots grinding backward across broken stone, and pushed back immediately.
She was stronger than he remembered.
Not by a small margin.
The Echo pressed forward without pause, blade coming down again before he had fully recovered from the first exchange. Shirou twisted, redirecting rather than blocking, letting the force bleed sideways — but she was already adjusting, already reading the redirect, the next strike arriving from a different angle before the last one had finished.
He was already behind.
"Trace on — trace on—"
Nameless swords erupted from the air around him in rapid succession, each one different — lengths varying, shapes differing, some curved, some straight, all of them built from the same cold prana flooding through circuits that weren't his. He hurled them forward without ceremony.
The Echo walked through them.
Steel shattered against her frame without slowing her stride — each blade breaking on contact, fragments scattering across the crater floor in sprays of dissipating light. The ones that carried enough magecraft to bypass her Dragon trait left marks — shallow, insufficient, nothing that changed the shape of the fight.
She locked blades with him.
The force drove him back two full steps, boots carving furrows through the broken ground. He planted his feet and held — for exactly as long as it took to realize holding wasn't working — then released and moved, circling left, forcing her to turn.
She turned faster than he did.
A flash of gold caught him across the ribs.
Shirou exhaled sharply, the impact registering across Shido's body in a deep, spreading ache. Not deep enough to cripple. Deep enough to remind him that these reserves weren't his to spend carelessly.
He disengaged, jumping back, buying himself three seconds of distance.
Three seconds.
He used them.
His eyes moved across her — stance, weight distribution, the angle her sword arm preferred on the downswing, the slight forward lean she carried into a charge. He had sparred against this style more times than he could count. He knew its rhythms the way he knew the feeling of a blade in his hand.
He also knew he was losing.
The memory came without invitation.
The Emiya manor dojo.
Late afternoon light came through the open screen doors in long, warm panels, cutting across the worn wooden floor in strips that shifted slowly as the sun moved. Outside, the garden was quiet. Inside, the sound of steel was not.
Saber came at him without announcement — the way she always did in practice, no warning, no preamble, because she had told him once that real opponents didn't offer either.
He caught the strike with both hands on the hilt, the impact rattling through his guard, and pushed back.
She let him push. Then redirected, and his momentum carried him sideways instead of forward, off-balance for exactly the half-second she needed.
The practice blade stopped at his throat.
Neither of them moved for a moment.
Then she lowered it.
"Again," she said.
He reset his stance without arguing.
They went again.
And again.
It was somewhere in the middle of the third exchange that she stopped mid-swing and lowered her blade entirely. Not a pause between strikes — a deliberate stop. The kind that meant the sparring was over and something else was beginning.
Shirou kept his guard up for a moment longer than necessary.
"You did it again," she said.
"Did what?"
"Your left side." Her eyes stayed on him, level and precise. "You left it open. Not because you failed to protect it — because you chose not to."
He said nothing.
Which was, as always, its own kind of answer.
Something shifted in Saber's posture. A stillness that was less about the body and more about what was behind it.
"Every time we spar," she continued, "you position yourself to absorb what should hit me. You do it even here, where there are no consequences, because it is not a habit — it is the way you think."
"I'm working on it."
"You are not." Her voice stayed even, but the words carried weight. "Shirou. You do not count yourself among the people worth protecting. That is not a minor flaw to be corrected in training. That is the way your mind works."
Shirou lowered his practice sword slowly.
"After Berserker—" He stopped. The words came out less steady than he intended. "I don't want to see you like that again. I know what you are. I know you're stronger than me in every way that matters in a fight." His jaw tightened. "But watching you take damage I could have taken instead — I can't just stand there. That's not something I know how to do."
Saber was quiet.
The afternoon light moved slowly across the dojo floor between them.
"You think placing yourself between harm and the people you care for is the correct answer," she said finally. "Regardless of the cost to yourself."
"I think—" He exhaled. "I think if I'm the one who gets hurt instead of you, that's the right outcome."
"It is not."
Simple. Certain. No anger in it — just the weight of someone who had thought about this for considerably longer than the conversation had been happening.
Shirou looked at her.
"Avalon lives inside me," he said quietly. "Your sheath. The thing made specifically to protect Excalibur — made for you." A pause. "I'm a sword. I decided that a long time ago. Something that exists to be used for others until it breaks. But if your sheath is inside me—"
His jaw tightened.
"Then maybe that's what I am. Not your shield. Your sheath." He exhaled. "And a sheath exists to take the damage so the sword doesn't have to."
Saber looked at him for a long moment.
Something moved through her expression — the particular look of someone who had just heard an argument that was both completely wrong and completely sincere, and didn't know which of those things to address first.
She crossed the distance between them in two steps and pressed her lips briefly against his — brief, certain, the same precision she applied to everything.
She pulled back and held his gaze.
"That," she said quietly, "is the most beautifully foolish thing you have ever said to me."
A pause.
"You chose to be a sword. I will not take that from you." Her voice stayed level. "But Kiritsugu placed Avalon inside you because he refused to let you die. Not because you were expendable — because you mattered to him."
Her eyes held his.
"A sword does not mourn being used. You do."
She picked up her practice blade and turned back toward the center of the dojo.
"Again," she said.
He picked his up.
They went again.
The memory dissolved.
Shirou came back to the present in pieces — the crater, the broken ground, the golden light of the Echo's blade filling his vision as she closed the distance he'd bought himself.
She was already on him.
He reacted on reflex, traced Excalibur coming up in a hard diagonal block that caught her blade and deflected it sideways. The force spun him slightly, and he used it — turning with the momentum instead of against it, putting himself at a better angle.
He looked at the Echo.
At the face that had said those words to him once, in a dojo with afternoon light coming through the screen doors.
*A sword does not mourn being used. You do.*
He looked at what she was now.
Something cold settled in his chest.
Not grief. Not anger. Just — clarity.
He stopped trying to match her.
He started thinking.
The crater was wide — roughly circular, the floor uneven, scattered with debris in patterns that weren't random if you read them correctly. She moved in straight lines when she had momentum. She favored the right side on the follow-through. Her guard tightened when she committed to a swing — the Dragon trait made her confident, made her willing to absorb hits she could have avoided, because until now nothing had given her reason not to be.
Shirou noted all of it.
He threw a traced sword — not at her, slightly wide, forcing her to track it. In the half-second her attention shifted he moved left, repositioning. She adjusted and came at him again.
He blocked. Gave ground deliberately. Let her push him back toward the crater's eastern edge where a collapsed section of pavement jutted upward at an angle.
She followed.
Of course she followed.
He threw three more swords in rapid succession — different trajectories, forcing her to read each one, her blade moving to intercept. The prana cost registered immediately, a cold drain pulling at reserves that were already running shallow. He kept going.
Another exchange — blades locking, close enough that he could feel the heat radiating off her armor. He pushed, she pushed back harder, and he let her — releasing suddenly so her momentum carried her forward a half-step, using that fractional imbalance to disengage and circle.
He'd done it.
Kanshou and Bakuya were already in the air.
He had thrown them two exchanges ago — wide, apparently careless, the kind of throw that looked like desperation. Black and white, mirror images curving away from each other across opposite sides of the crater.
They were already finding each other.
The Echo didn't know they were behind her.
Shirou raised his traced Excalibur.
He looked at her — at the Echo, at the golden blade rising to meet his, at the stance he had been watching build for the last thirty seconds.
She was about to release her Noble Phantasm.
He knew that stance.
He raised his sword anyway.
*This is going to hurt.*
Twin pillars of light erupted skyward simultaneously, tearing upward through the cloud layer in blinding columns that turned the underside of the sky white. White feathers spiraled outward from both points as the energy gathered, pressing down on the crater with a weight that had nothing to do with physics.
"Excalibur!"
Both voices rang out at once.
The beams descended.
They collided between them with an impact that shook the crater floor — a deep, resonant concussion that radiated outward through the broken ground in visible waves, dust jumping from every surface simultaneously.
"Ahhhh—!"
Shirou screamed.
His reserves dropped in a single violent plunge — not gradually, not in stages, but all at once, the traced Excalibur demanding everything left in circuits that had been running shallow since the first exchange. His pillar of light buckled immediately under the Echo's overwhelming output, the beam bending backward toward him degree by degree.
He held it.
One second.
Two.
His arms shook. His vision blurred at the edges. The prana cost of maintaining the trace climbed with every heartbeat, the circuits in Shido's body screaming at a frequency just below sound.
Three seconds.
He smirked.
From either side of the Echo — black and white.
Kanshou and Bakuya arrived.
Her hands were locked around her Noble Phantasm. Her full output committed to the beam between them. There was no defense available, no adjustment possible, no way to respond to an attack she hadn't seen coming because it had been set up twelve exchanges ago and had been waiting ever since.
The twin blades struck.
Her stance shattered.
The beam wavered — just enough, just for an instant — and in that instant Shirou released his traced Excalibur completely, the collapsing pillar redirecting outward rather than backward, the accumulated force of both beams detonating sideways across the crater in a blinding discharge that swallowed everything.
The explosion faded.
The sky cleared slowly, light bleeding back into something normal.
Shirou dropped to one knee.
His breath came in hard, uneven pulls, each one costing more than it should. Shido's body had nothing left — circuits cold, reserves emptied, every muscle trembling with the particular exhaustion that came after pushing past what a body was built to sustain.
He had done it.
A single card drifted down from the clearing sky.
He watched it fall.
His arm rose — slowly, the motion costing him — and he caught it between two fingers.
He looked at it for a long moment.
Then his gaze lifted to the space where the Echo had been.
"It's over now, Saber…"
The words came out quietly. No performance in them. Just the fact of it, stated plainly.
A breath passed.
Then, quieter still — the voice of someone finishing a thought they had been carrying for a very long time:
"I told you I was your sheath."
He exhaled once — long, controlled.
"So I'll keep doing what a sheath does."
His grip tightened slightly around the card.
"No matter how long it takes — no matter what world I have to search through — I'll find my way back to you."
The words didn't go anywhere. There was no one left to receive them.
He said them anyway.
"Guess I owe the kid."
His vision darkened at the edges, the crater tilting slightly as his body finally submitted to the debt it had been running up since the first exchange.
He collapsed.
The card still held between his fingers.
