Griswald opened his eyes to a ceiling that wasn't there.
Exposed rebar. Crumbling concrete. A water stain shaped like something he couldn't name spreading across what remained of the second floor above them. The red sky bled through gaps where the roof had been, painting everything in tones of rust and old copper.
He blinked and felt around for his glasses finding them on the ground before returning them to his face. His back ached from the concrete beneath the thin layer of cloth and cardboard they'd arranged into something that mocked the word "bedding." His left arm had gone numb where it pressed against a chunk of drywall.
But his right hand was warm.
Mash's fingers were still laced through his. She sat beside him with her shield propped against her shoulder, her violet eyes tracking a slow sweep of the perimeter before settling on his face.
"Senpai." The word carried relief she didn't try to hide. "How did you sleep?"
Griswald sat up. His spine popped in three places. He pushed his glasses straight with his free hand and ran his fingers through hair that really needed a wash.
The dream clung to him—gray hair, a knight who searched inside himself for emotion and found only absence. A dark-armored figure speaking of betrayal. The absolute nothing where feeling should have been, vast and clean and terrifying in its completeness.
"Strange dreams." He rubbed his face with both hands. "I don't know what to make of them."
Mash tilted her head. Waited. When nothing else came, she nodded—a small, patient gesture that said she would not push.
"You've been asleep for approximately four hours. No enemy activity in the immediate area."
"Four hours." He felt like he'd slept for twenty minutes. Or twenty years. Some duration that didn't match what his body was telling him. "You should have woken me. You need rest too."
"I'm fine, Senpai."
She wasn't fine. Dark smudges lived beneath her eyes, and her shield arm held a tension that spoke of hours maintaining the same position. But he'd learned already that arguing with Mash about her own wellbeing produced results roughly equivalent to arguing with a wall—less, actually, since a wall wouldn't look at him with those earnest violet eyes and make him feel guilty for caring.
Footsteps scraped across rubble. Ritsuka ducked through the gap in the wall that served as their entrance, her orange-red hair catching what passed for light in this place. She carried two dented cans with no labels.
"Morning. Or evening. Or whatever this is." She dropped into a crouch beside them. "I found these in the basement. Could be peaches. Could be motor oil. Want to gamble?"
"I'd rather not."
"Wise man."
Olga appeared behind Ritsuka, stepping through the gap with the precise, deliberate movements of someone who refused to let rubble touch her coat. She'd somehow kept the black tailored fabric presentable through this hellscape. Griswald suspected magic was involved.
"You're awake." Olga's golden eyes swept over him with clinical efficiency. "Good. We've lost enough time."
"Any word from Dr. Roman?"
Olga's jaw tightened. "Romani is occupied. The explosion damaged more of Chaldea's infrastructure than initial assessments suggested. He's managing simultaneous failures across life support, power distribution, and the remaining SHEBA systems." Her voice carried the flat precision of someone reciting facts to avoid dwelling on what they meant. "Fires, both literal and figurative. He'll establish contact when he can."
So they were on their own. Griswald absorbed this without surprise—surprise required expectations, and he'd stopped expecting anything resembling good news approximately twelve hours after arriving in this burning graveyard of a city.
"Right." He stood. His knees protested. His runes itched where Cú had carved them into his arms, the lines pulsing faintly with residual energy. "Then we should—"
Blue light flickered between Ritsuka and Olga.
Cú Chulainn materialized from spirit form like a man stepping through a curtain. One moment, empty air. The next, six feet of blue-haired druid leaning on his staff with the casual ease of someone who'd been standing there the entire time.
Ritsuka yelped and threw a can. Cú easily dodged and it clanged against Olga's shin.
"Fujimaru!"
"Sorry! Sorry, reflex—"
Olga hopped on one foot, clutching her leg. "You absolute—of all the undisciplined, barbaric—"
Cú watched the display with naked amusement, his earrings catching light as he turned his head between them. He let it play out for precisely as long as it entertained him, then rapped the butt of his staff against the concrete floor. The sound cut through Olga's tirade and Ritsuka's stammered apologies.
"Good, you're all here." His crimson eyes moved across each face—Griswald standing, Mash rising beside him with her shield, Ritsuka frozen mid-apology, Olga mid-fury. He took inventory of the group some calculation turning behind those sharp, narrow eyes.
Then he smiled. Not the lazy grin he wore when teasing. Something harder. Something that belonged to the man who'd put a staff through the Archer's chest.
"Saber hasn't moved. The Grail's still pulsing. We don't get a better window than this." He planted his staff and leaned forward. "Time to plan how we kill the King of Knights."
The shelter went quiet. Even the ambient groaning of stressed concrete seemed to hush, as if the ruined building itself wanted to hear what came next.
Cú let the silence breathe for a moment, then killed it.
"I'm going to be brutally honest with you. All of you." He swept his gaze across the group, lingering on each face long enough to make his point. "Saber outclasses us. In almost every measurable field. Strength, speed, instinct, raw destructive output. She is faster than any of us can track, stronger than anything we can block, and more dangerous than all of us combined."
The words landed like stones dropped into still water. Griswald felt Mash stiffen beside him. Ritsuka's hand drifted to her side. Olga's expression didn't change, but the color left her knuckles where they gripped her elbows.
Nobody spoke. Cú didn't wait for them to.
"She is the King of Knights. Not a title. Not a legend someone inflated over centuries of retelling. That woman earned every syllable of it on battlefields that would make this—" He gestured at the burning skyline beyond their shelter. "—look like a campfire. Even before the Grail corrupted her, she was the most competent Servant in this War. Artoria Pendragon doesn't have a weakness worth exploiting. She has preferences. Habits. Patterns a clever man might read if he lives long enough to see them twice." His mouth curved. "Most don't."
"You fought beside her," Griswald said. "Before the corruption. You must have observed—"
"Observed her killing everything that got within sword range, yeah." Cú rolled his staff between his palms, the carved runes along its length catching the red light. "Which brings me to my problem. My biggest advantage is range. Runecraft, fire, ice, barriers—everything I do works best when I've got distance to work with. Space to think. Room to layer traps and shape the ground before the enemy reaches me." He stopped rolling the staff. Held it still. "Saber doesn't give you distance. I watched her fight during the War. Briefly. From concealment. She crossed forty meters of open ground in the time it took a Servant—not a human, a Servant—to loose two arrows. Forty meters. Gone."
"So you can't kite her," Ritsuka said.
"I can try. Once. If I'm lucky, I get off one or two good hits before she's in my face." He tapped the staff against the floor. "And here's the other thing. Sabers get Magic Resistance as a class skill. High rank. The corruption might have altered it, might not—I'm not gambling our lives on 'might.' What that means in practice is my runes won't stick the way they did with Archer. Fire that melted through his armor? She'll walk through it. Ice that locked his feet? She'll shatter it without slowing down. The stuff that won me that fight becomes background noise against her."
Olga exhaled through her nose. A controlled sound, but Griswald caught the frustration coiled inside it. She was doing the same calculations he was, arriving at the same answers.
"My barriers will still function as physical obstacles," Cú continued. "Walls of ice are still walls. Flame is still hot. But the magical component—the part that makes runecraft dangerous, that imposes meaning onto reality and forces it to comply—gets filtered. Diluted. She'll feel my best work the way you'd feel a stiff breeze."
He turned to Mash.
She met his gaze without flinching, but Griswald saw her fingers tighten around the cross-shaped shield's grip. The massive thing stood taller than she did, its surface scored with fresh marks from the Archer's swords.
"Your shield." Cú pointed at it with the head of his staff. "That's real. Whatever Heroic Spirit gave you that thing built it to stop what shouldn't be stoppable. Against Saber, your defense is genuine. You can take her hits. Probably the only one here who can."
A fraction of the tension left Mash's shoulders.
Cú destroyed it immediately.
"But defense alone doesn't win fights. It delays losing." He held up a hand before Mash could respond. "I'm not questioning your courage, girl. I watched you pin Rider against a wall and crack her ribs with that shield. You've been given instincts most warriors spend decades grinding into themselves. But Saber isn't Archer. Archer fought with calculation—angles, distance, economy. He retreated when pressed. Saber doesn't retreat. Saber advances. Every block you make, she'll read. Every parry, she'll adjust. You hold your ground and she'll grind you down through sheer accumulated pressure until your arms give out or your mana runs dry."
He let the silence hold again.
"And mana will run dry. Blocking a Noble Phantasm-class weapon takes energy. Absorbing the force takes energy. Maintaining your armor, reinforcing your footing, keeping your Spirit Origin intact while something that powerful hammers you—it all costs. You can't just plant your shield and outlast her. That's a war of attrition against an opponent drawing power directly from a corrupted Holy Grail." He shook his head slowly. "Infinite battery versus a limited one. The math doesn't work."
Mash's grip on her shield hadn't loosened. If anything, it tightened further, the leather of her gauntlets creaking softly. Her jaw was set, her violet eyes fixed on Cú with an intensity that bordered on defiance—not at his assessment, but at the reality behind it.
Griswald turned to Mash. The words gathered somewhere in his chest—something about how they'd find a way, how she wasn't alone in this, how her shield had already stopped things that should have killed them both. But the words tangled before they reached his mouth. Every reassurance he could think of sounded hollow against the assessment Cú had just delivered. Mash didn't need platitudes. She needed a plan.
He closed his mouth. Squeezed her hand once instead. She glanced at him, and something in her expression softened—just barely, just enough.
Ritsuka broke the silence with a slow, theatrical clap.
"Wonderful briefing. Really inspiring stuff." She leaned back against the crumbling wall and folded her arms. "So just to recap—she's faster, stronger, tougher, magically resistant, and running on infinite mana from a corrupted wish-granting device. Is there any advantage she doesn't have, or should we just walk into the fire now and save her the trouble?"
Cú's mouth twitched. He tilted his head, earrings swinging, and matched her tone with surgical precision.
"Funny you should ask. There are a few rather significant ones she's missing."
Every head in the shelter turned.
Olga unfolded her arms. Ritsuka's sarcasm evaporated. Mash straightened. Even the ambient creak of the building seemed to pause, as if the ruins were eavesdropping again.
Cú held the moment. Drew it out. Then he tapped his temple with one finger.
"Her mind."
He let that land before continuing.
"You've all been thinking of Saber as Artoria Pendragon—the ruler who unified Britain, the king who held together a fractured kingdom through will and power. Forget that person. She doesn't exist anymore." He paced a slow line across their shelter, staff clicking against the floor with each step. "What's standing at the center of this Singularity is a weapon. A very powerful, very dangerous weapon. But a weapon without a hand to guide it."
Olga's eyes narrowed. "You're saying the corruption destroyed her consciousness?"
"Not destroyed. Drowned." Cú stopped pacing. "I've been thinking about this since the fire started. Three days watching her from concealment, studying what the Grail did to her and the other Servants. The pattern held for most of them—corruption seeped in, twisted their Spirit Origins, turned them violent and cruel. Quick. Easy. Like ink dropped into water."
He held up a finger.
"But Artoria isn't water. She's stone. Two layers of resistance the corruption had to break through before it could take hold. First—Magic Resistance. Saber class, high rank. The same thing that makes my runes useless against her would have fought the Grail's corruption on a fundamental level. Her Spirit Origin would have rejected it the way a body rejects poison. The corruption couldn't just seep in. It had to force its way through."
A second finger.
"Second—her nature. This is the woman who pulled a holy sword from a stone and chose to sacrifice everything personal about herself for a kingdom that ultimately betrayed her. Duty. Righteousness. An ideal so rigid it broke everyone around her, including herself. That kind of conviction doesn't corrupt easily. It's not a flaw the Grail can exploit—it's a fortress. The corruption would have had to match her will with something stronger just to get a foothold."
He dropped his hand.
"So what does the Grail do when the standard amount of corruption bounces off? It pours in more. And more. And more. Layer after layer of the stuff, burning through her resistance through sheer volume until her Spirit Origin finally cracks under the weight. And what's the first thing that drowns when you flood a person with that much foreign power?"
"Higher cognitive function," Griswald said quietly.
Cú pointed his staff at him. "Give the healer a prize."
The pieces clicked together in Griswald's mind—the clinical part of his brain, the part that had spent years studying how magical saturation affected biological systems, already running ahead.
"She still has her instincts," he murmured. "Muscle memory. Reflexes. A Heroic Spirit's combat ability isn't purely cognitive—it's written into the Spirit Origin itself. But tactical reasoning, strategic planning, the ability to adapt to novel situations..."
"Gone. Mostly." Cú's expression carried a strange blend of satisfaction and something that looked almost like mourning. "The King of Knights reduced to a beast with a sword. The Grail traded her brilliance for obedience. She'll fight with everything she has, and what she has is terrifying. But she won't think. She won't set traps. Won't feint. Won't sacrifice position for advantage three moves ahead the way the real Artoria would."
Ritsuka sat forward. "That's one. You said a few."
"The second ties to the first." Cú planted his staff and leaned on it. "She's chained to the Grail. Literally cannot leave its side. The corruption runs through her like a leash—she guards it because the Grail makes her guard it. Which means she has two jobs: protect herself and protect the thing feeding her power." His grin turned sharp. Wolfish. "Two targets. One guard. If we can force her to choose between defending the Grail and defending herself at the same time—"
"We split her attention," Olga finished, her golden eyes brightening with the spark of genuine calculation.
"Better than that." Cú's voice dropped low. "The Grail isn't her ally. It's her owner. And if that owner has to choose between preserving its guard dog and preserving itself?" He drew a finger across his throat. "The Grail will sacrifice her without a second thought. Feed her every drop of power it has left in one suicidal burst, burn her Spirit Origin to ash, and use the explosion to protect itself. We don't just split her attention—we put her in a position where the thing keeping her alive decides she's more useful dead."
The logic crystallized in Griswald's mind like ice forming on glass. He could see it now—the shape of the strategy emerging from everything Cú had laid out. Two targets, one guard, a leash that could become a noose.
"So we need to damage the Grail," he said slowly, testing the words against the framework Cú had built. "Force it into a position where it has to—"
"The Grail isn't fragile."
Olga's voice cut across his like a blade through silk. She stepped forward, arms folded tight beneath her chest, chin lifted at that particular angle Griswald had already learned meant she was about to deliver information she considered herself uniquely qualified to provide.
"My father won the Fuyuki Holy Grail War." No hesitation. No softening. She stated it the way someone might state that water was wet—as immutable fact. "The 2004 iteration was his victory. And after his victory, he conducted extensive research into the Grail's structure, its composition, its vulnerabilities—or rather, its lack of them." Her golden eyes swept the group. "I've read every note he left. Every analysis. Every classified document locked behind three layers of magical encryption that I spent two years decoding after his death."
She paused. Let the weight of that settle.
"The Holy Grail is not a cup. It is not an artifact in any conventional sense. It is a self-sustaining magical reactor built from concentrated the fabled Third Magic—the materialization of the soul itself. Its outer shell exists partially in this dimension and partially in a space between worlds where physical laws become suggestions. My father's notes describe it as closer to a miniature Reality Marble than an object." Her voice carried the crisp, lecture-hall cadence of someone who had memorized these facts until they became part of her. "Conventional magecraft cannot damage it. Noble Phantasms below a certain threshold cannot damage it. Even Anti-Army class constructs would splash against its surface like rain against stone."
She looked directly at Cú.
"Nothing any of us possess can scratch it."
The silence that followed wasn't the stunned kind. It was the kind that settled over a group of people confirming what they already suspected—that the mountain before them was exactly as tall as it looked.
Cú met Olga's stare. Held it. Then his mouth split into a grin so sharp it could have drawn blood.
"Couldn't agree more."
Griswald blinked. Ritsuka cocked her head. Mash's brow furrowed behind the edge of her shield.
"None of us can damage it," Cú repeated, savoring each word like he was tasting wine. "So we won't. We'll get someone else to do it for us."
The grin widened. He leaned on his staff and waited. The shelter filled with the sound of four people thinking very hard and one person enjoying the fact that they hadn't caught up yet.
Ritsuka got there first.
Her amber eyes went wide. Then narrow. Then wide again as the implications hit her in sequence, each one worse than the last.
"You absolute lunatic." A breath of disbelief that was half laugh, half horror. "You want Saber to do it. You want the King of Knights to destroy her own Grail."
Cú tapped his nose with one finger.
"Excalibur." He spoke the name with the reverence of someone who'd seen what it could do. "The Sword of Promised Victory. If anything in this Singularity can crack open a Holy Grail, it's the weapon already in Saber's hand."
Olga's composure fractured. Not much—a hairline crack that showed in the slight parting of her lips and the way her folded arms tightened against her ribs. "You want to trick a corrupted Heroic Spirit into using the most destructive Noble Phantasm in this Singularity against the very thing sustaining her existence."
"Trick. Bait. Maneuver. Pick whichever word makes you comfortable." Cú shrugged with the easy indifference of a man discussing dinner plans. "Our best path to victory runs through one of two scenarios. Either we position ourselves so that Saber fires Excalibur and hits the Grail instead of us—"
He raised one finger.
"—or we box her in so tight that she can't fire Excalibur without the blast catching the Grail in its radius. Pin her between us and the thing she's supposed to protect. Make the leash work against her." A second finger. "She's lost her tactical mind, remember. The real Artoria would never put herself in a position where her own Noble Phantasm endangered her power source. But this version? This drowning, corrupted weapon the Grail is puppeting around? She'll swing at whatever threatens her. She'll react. And reactions can be guided."
He brought both fingers together and mimed an explosion.
"Either she destroys it for us, or she destroys herself trying not to."
Nobody spoke for a long moment. The plan hung in the air between them—audacious, desperate, and built on a foundation of calculated insanity that Griswald recognized as their only real option.
Mash was the one who finally broke the silence, her quiet voice carrying a question that Griswald realized he should have asked first.
"How do we survive long enough to position her?"
Cú's mouth split into something that belonged on a predator—all teeth, no warmth. The kind of smile that made Griswald's hindbrain whisper run even though it wasn't aimed at him.
"How do we survive long enough?" Cú repeated Mash's question back to her, rolling the words around his mouth like he was tasting them. He let the silence stretch. His crimson eyes swept across each of them—Mash gripping her shield, Ritsuka leaning forward, Olga rigid with her arms crossed, Griswald standing between them all with a hand still unconsciously reaching for Mash's.
"No idea."
The words hit the shelter like a brick through glass.
Mash blinked. Ritsuka's jaw dropped. Griswald felt something cold settle in the pit of his stomach.
Olga erupted.
"What do you mean you have no idea?!" Her face went from porcelain to scarlet in the span of a single breath. She lurched forward, the tails of her black coat snapping behind her, one finger stabbing at Cú's chest like she intended to drill through it. "You just spent—you stood there and laid out this entire strategy about corrupted minds and splitting attention and making her destroy her own Grail, and your answer to 'how do we actually do that' is you have no idea?!"
Cú didn't flinch. Didn't step back. Didn't even shift his weight on the staff. He just watched her the way a cat watches a particularly energetic mouse.
"Are we supposed to just—just charge at the King of Knights and hope for the best?"
"Yes."
The single syllable landed like a slap. Olga's mouth opened. Closed. Opened again. No sound came out. Her golden eyes bulged with a fury so complete it had apparently short-circuited her ability to produce language.
Cú filled the gap she couldn't.
"No plan survives contact with the enemy." He spoke without his usual theatrical cadence. The teasing evaporated. The lazy grin vanished. What remained was the voice of a man who'd fought in wars that became legends, stripped of everything except hard-won truth. "That's not a proverb. That's not something clever men say to sound wise at feasts. It's the single most important lesson any warrior learns, and most learn it by dying."
He stepped past Olga. She stumbled sideways, too startled by his sudden seriousness to maintain her ground.
"Saber is not an ordinary enemy. She is not an enemy you can plan for. I told you—she's lost her tactics, her strategy, her ability to think three moves ahead. That makes her less dangerous in some ways and infinitely more dangerous in others. A thinking opponent is predictable. They have goals. Priorities. Patterns your mind can latch onto and anticipate. A weapon with no mind behind it?" He held up his staff horizontally, balanced on one finger. "It just cuts whatever's in front of it. No hesitation. No doubt. No gap between intent and action for a clever plan to exploit."
The staff tilted. Fell. He caught it before it hit the ground.
"Any plan detailed enough to account for her speed would be obsolete the moment she moved faster than we predicted. Any formation designed to contain her would shatter the instant she decided to go through it instead of around it. I can give you the shape of what we need to accomplish. I can give you the goal." He planted the staff. The sound echoed through the broken shelter. "Getting there? That's going to come down to what each of you does in the moment. Reacting. Adapting. Making decisions faster than you've ever made them in your lives."
His eyes found Griswald's. Held them.
"We do our best." The sharp smile returned, but gentler now. Tired around the edges. "Not like we've got better options."
Olga's composure reassembled itself in fragments—spine straightening first, then shoulders squaring, then chin lifting to its customary angle. The flush hadn't fully retreated from her cheeks, but her voice came out steady. Controlled. The voice of a Director.
"No."
Cú raised an eyebrow.
"I am not signing off on a plan that has no plan." Each word landed with deliberate weight, spaced and precise, as though she were dictating terms to an adversary across a negotiation table. "The probability of victory is already microscopic. You've spent the last ten minutes explaining exactly how microscopic. And your proposed solution to that problem is 'improvise and pray?' That reduces our chances from slim to functionally nonexistent."
"Heroes aren't made by fighting battles they know they'll win, Director."
"We are not trying to be heroes!" The word cracked out of her like a whip. Her golden eyes blazed—not with the theatrical fury from before but with something rawer. Something that lived closer to the bone. "We are trying to make it out of here alive. All of us. Every single person in this room. That is my responsibility. That is my job." Her voice dropped. Not quieter—heavier. "I am the Director of the Chaldea Security Organization. The lives of everyone under my authority are mine to protect. I will not throw them away on a gamble dressed up as strategy."
Something cracked behind Olga's composure. Not the theatrical fury she wielded like a weapon, not the imperious disdain she used as armor. This was the woman underneath all of it—the one who'd inherited a dead man's legacy and spent every waking moment terrified she wasn't enough to carry it.
Griswald felt his throat tighten. He glanced sideways.
Mash's violet eyes had gone soft. Her grip on the shield slackened, fingers loosening their white-knuckle hold for the first time since Cú began his briefing. Ritsuka's expression had lost its perpetual edge of sardonic detachment. Her amber eyes were wide, lips slightly parted.
Griswald understood, with a clarity that surprised him, that nobody had ever heard Olga Marie Animusphere say those words before. Not like that. Not stripped of pretense and rank and the cold architecture of authority she built around herself like a fortress. She hadn't said I am in charge. She'd said these lives are mine.
And she meant it.
Cú's face went still. The sharp grin dissolved. The lazy posture straightened by degrees until the man standing before Olga bore no resemblance to the irreverent druid who'd spent the past day needling everyone within earshot. His crimson eyes held hers without blinking, without the theatrical pauses he used to build dramatic tension. Just steady, unbroken contact between two people who understood what it meant to carry weight.
"Being a leader," Cú said, and his voice was smooth and steady as river stone, "means sending people into battles they might not come back from."
Olga flinched. A micro-movement—a tightening of the skin around her eyes, a fractional pulling back of her chin—that she smothered almost before it appeared.
Cú didn't let her recover.
"It means looking at the people who trust you, who depend on you, who believe that your judgment is the difference between their survival and their death—and telling them to walk into fire. Knowing some of them won't walk out." His voice carried no cruelty. No challenge. The words fell with the weight of something he'd lived through enough times to speak about without flinching. "That's not a failure of leadership, Director. That's the cost of it. Every commander who ever mattered understood that. Every king, every general, every fool who stood at the front and pointed the way forward. The ones who couldn't pay that price got more people killed trying to avoid it than they ever would have lost by accepting it."
He shifted his staff from one hand to the other. A slow, deliberate movement.
"The path to victory here is narrow. I won't pretend otherwise. But it exists. It runs through this plan—through Saber, through Excalibur, through forcing that corrupted Grail to eat itself. That's what we have. That's all we have. And the risk?" He met her gaze without wavering. "The risk is necessary. Because the alternative isn't safety. The alternative is certainty. Certain failure. Certain death. Not just for us—for everyone depending on Chaldea to fix what's broken."
Gold met crimson across three feet of ruined shelter. Neither blinked.
Olga's hands had curled into fists at her sides. Her knuckles were bone-white beneath the skin, tendons standing out like cables beneath the elegant lines of her wrists. When she spoke, her voice carried an edge that could have split iron.
"Don't." The word came out serrated. "Don't presume to lecture me about risk."
She stepped forward. Into his space. Close enough that she had to tilt her head back to hold his eyes, the height difference between them stark and irrelevant against the force of her presence.
"I am a magus, Cú Chulainn. A magus of the Animusphere bloodline. We walk with death from the moment we open our first circuit. Every spell we cast is a negotiation with forces that would unmake us if our concentration slipped for a single heartbeat. Every ritual we perform is a transaction where the currency could be years off our natural lifespan." Her chin rose higher. "I have felt my own magic eat the lining of my nerves to fuel a thaumaturgical formula. I have watched colleagues—people I knew—reduce themselves to catatonic husks because they reached three millimeters past their limits on a Tuesday afternoon. Do not stand there and tell me about risk as if I am some sheltered child who needs the concept explained."
"Then act like it." No heat. No mockery. Just the flat, unadorned challenge of a warrior who respected her enough to stop being gentle. "You know the stakes. You know the odds. You know there's no safe path through this. So stop looking for one and start figuring out how to walk the dangerous one without getting us all killed."
"That is precisely what I'm—"
"No, you're arguing about whether the path should exist at all. It does. Accept it and move."
They stood there, locked in a stalemate that crackled with enough tension to ionize the air. Neither yielded. Neither advanced. The argument had reached the point where words became weapons swung in circles, each strike landing in the same place, neither combatant willing to step back.
Mash's voice cut through it like water through dust.
"Director Animusphere."
Quiet. Gentle. Absolutely immovable.
Both heads turned.
Mash's gaze dropped to her shield. The massive cross-shaped slab of metal and mystery that had stopped a corrupted Rider's scythe, deflected an Archer's rain of swords, and absorbed impacts that should have shattered stone.
Her violet eyes lifted. Found Griswald's.
Something passed between them in that half-second of contact. Not words. Not even a fully formed thought. Just recognition—the kind that lived beneath language, in the place where two people who had nearly died together understood each other without needing to explain why.
Then she turned to Cú and Olga.
"I'll do it." No tremor. No hesitation. The words came out with the same quiet steadiness she used when she said Senpai after a battle—gentle on the surface, bedrock underneath. "Cú Chulainn's plan. I'm ready."
"Kyrielight—"
"I know." Mash's grip shifted on the shield. Her knuckles whitened, the leather of her gauntlets groaning as her fist tightened around the handle. The muscles in her bare shoulders drew taut beneath her combat armor. "I know that if I had the Heroic Spirit's true name—if I could activate my Noble Phantasm at full power—this would be different. We'd have options. Real ones. A defensive Noble Phantasm at full strength against Excalibur might actually—"
She stopped herself. Drew a breath. Let the fist loosen by force of will, one finger at a time.
"But that doesn't mean I don't want to be out there." Her voice dropped but didn't weaken. "It doesn't mean I should stay behind. I can't access everything this shield can do. That's true. But what I can do—what I've already done—" Her eyes moved across each of them. "If all of you believe there's a chance—even a narrow one, even one built on improvisation and desperation—then it's my job to make that chance real."
Her gaze settled on Griswald.
"It's my duty as your Servant, Senpai." The formality of the words couldn't disguise what lived behind them. "Your goal becomes my purpose. That's what this contract means. Whatever you decide to reach for—I will be the shield covers you so that you get there."
Griswald's chest did something he couldn't name. Not tightening—expanding. As if a space inside him that had been compressed for years, crushed small by rejection letters and disappointed parents and the constant grinding certainty that he wasn't enough, suddenly cracked open. Air rushed in. Light followed.
He looked at Mash—at this girl who'd been engineered in a laboratory and never once been asked what she wanted—and understood with absolute, bone-deep clarity that she had just handed him something no one in his life had ever offered.
Something burned behind his eyes. He blinked it away.
"Then as your Master—" His voice cracked on the word. He cleared his throat, pushed his glasses up his nose with a knuckle, and tried again. Steadier this time. Not much, but enough. "As your Master, it's my job to be there with you. Every step. Making sure you have everything you need to succeed." He held her gaze without flinching, without the habitual slouch that made him smaller than he was. For once, he stood at his full height. "You're my shield, Mash. So I'll be your supply line. Your healer. Your anchor. Whatever you need me to be so you can do what you were made to do."
Mash's face did something extraordinary.
It started at her eyes—a softening that dissolved the combat-ready focus she'd maintained since Cú's briefing began. The tension drained from her brow, smoothing the faint crease between her eyebrows. Her lips parted by a fraction, the set line of her jaw releasing into something unguarded. Color bloomed across her pale cheeks—not the flush of embarrassment she'd shown during their mana transfers, but something warmer. Deeper. A heat that started behind her sternum and radiated outward until it painted her skin in shades of rose that had nothing to do with the red sky above them.
Griswald didn't recognize what he was seeing. He catalogued the physical signs—pupil dilation, increased blood flow to the facial tissue, involuntary relaxation of the musculature around the mouth—and filed them under relief or gratitude or the natural aftermath of emotional tension, because those were categories his analytical mind could process.
The category it actually belonged to didn't occur to him.
Olga watched the exchange with her mouth slightly open. Her golden eyes moved between them—from Mash's radiant, unguarded face to Griswald's earnest, oblivious sincerity—and something shifted behind her expression. The rigid architecture of objection that had held her spine straight and her jaw locked began to fracture. Not from Cú's arguments. Not from logic or strategy or the cold mathematics of survival.
From this. From two people who had every reason to be afraid choosing to face that fear together without pretense or calculation.
Her throat worked. She looked away. Looked back. Pressed her lips into a thin line that trembled at the corners before firming into something that resembled resolve.
"Very well."
The words came out clipped. Professional. Stripped of everything except the authority vested in her title and the weight of the decision behind it.
"As Director of the Chaldea Security Organization, I am formally authorizing this operation." She squared her shoulders. Met Griswald's eyes first, then Mash's. "Master Griswald Von Garmisch and Servant Mash Kyrielight are approved to undertake the assault on the corrupted Holy Grail under the tactical framework proposed by the Caster-class Servant Cú Chulainn." A pause. Barely perceptible. "I expect both of you to return. That is not a request."
Griswald nodded. Mash nodded. Something unspoken passed between all three of them—an acknowledgment that the decision had been made and the ground beneath their feet had shifted permanently because of it.
Two arms draped themselves across Griswald's and Mash's shoulders simultaneously.
Ritsuka materialized between them with the predatory cheer of someone who'd been waiting for the emotional crescendo to peak before inserting herself directly into its center. Her amber eyes sparkled. Her grin stretched wide enough to split her face.
"Great news, everyone! We're all going to die!"
"Fujimaru, that is entirely inappropriate—"
Cú's laugh cracked across the shelter like a thunderclap. Genuine. Unrestrained. The kind of laugh that belonged around a campfire after a battle, fueled by mead and survival and the giddy relief of still being alive to make noise. He threw his head back, blue hair catching the red light, earrings swinging wild, and let the sound fill every crumbling corner of their pathetic excuse for a headquarters.
"Leave her alone, Director." He wiped his eye with the back of his hand, still grinning. "Nothing wrong with a bit of humor before a fight. Better to laugh walking in than crying."
Olga's face compressed into a configuration that suggested she had opinions about this philosophy. Detailed, vigorous opinions that she was choosing—with visible, physical effort—not to voice. A sound escaped her. Not quite a word. More like the death rattle of a reprimand that had been strangled in its crib by the realization that arguing would accomplish nothing.
"Hmph."
Cú straightened. His expression shifted—still carrying traces of genuine mirth but overlaid now with purpose. The warrior reasserting itself over the comedian.
"Right. Here's what happens next." He pointed his staff at Mash. Then at Griswald. "You all go have fun then and fill her up. As much as you can manage. Every drop of mana you can squeeze out of those circuits goes into her reserves. We hit Saber immediately after."
Heat detonated across Griswald's face. Mash's shield jerked upward half an inch—an involuntary defensive reflex triggered not by any physical threat but by the nuclear blush that consumed her from collarbones to hairline.
"When—when you say all—" Griswald's voice emerged approximately two octaves higher than intended. "You mean—all of—everyone should—?"
Cú swept his gaze across the group with the expression of a man observing particularly slow livestock.
"We could all be dead within the hour." He said it without drama. Without weight. A simple observation of fact, delivered with the same casual tone he might use to note the weather. "Every person standing in this shelter might cease to exist before the night is over. Given those circumstances—" He shrugged, both palms upturned, staff balanced in the crook of his elbow. "—I see no reason anyone shouldn't enjoy themselves before we march."
Ritsuka's laugh rang sharp and delighted against the concrete walls. Her amber eyes cut toward Cú with undisguised interest. "Does that invitation extend to you, oh wise and ancient Caster? Care to join the festivities?"
Cú shook his head. The motion was slow, almost fond, accompanied by a half-smile that carried the sediment of old memories.
"I've had enough trouble with women to last more than a few lifetimes." Something flickered behind his crimson eyes—a shadow that passed too quickly to name. "Go on." His staff swung between Mash and Griswald like a compass needle finding north. "She'll need every scrap of mana you can pour into her for what's coming. Don't hold back."
Griswald's blush achieved a shade of red that he was fairly certain didn't exist in nature. Beside him, Mash gripped her shield with both hands and stared at a fixed point on the far wall with the desperate concentration of someone attempting to teleport through sheer force of will.
Neither of them moved.
Neither of them disagreed.
