The air on the outskirts of the distorted Washington D.C. was thick, charged with static electricity, the cloying scent of corrupt Celtic magic, and the acrid stench of burnt oil and hot metal from Edison's machinery. The fortress-city rose before them like a two-headed monster, each biting the other in perpetual war. But Leonel Herrera no longer saw it as an impenetrable mass of chaos. His mind, now tempered by Scathach's test and enhanced by Tezcatlipoca's evolution, saw lines, vectors, pressure points. He saw a giant chessboard, and he had the pieces to play.
From his position on a high plateau to the southwest, with a clear view of the walls and the battlefield stretching before them, Leonel initiated the operation. Beside him, Mash Kyrielight, his unshakable rock, and Nero Claudius, his loyal empress, flanked his position. They weren't just protection; they were emotional anchors and physical extensions of his will. Behind, like a supportive shadow, Tamamo no Mae refused to move from his side, her nine tails slightly bristled, her golden eyes scrutinizing every movement. Kiyohime, in a state of perpetual alert, guarded his rear, her burning gaze promising hell for anyone who approached.
And then there was Tezcatlipoca. The Persona had transcended its previous form. It was no longer just a navigator or a tactical advisor. It was a living command center. Its figure, imposing and serene, seemed to blend with the charged air, its cosmos eyes reflecting not stars, but the flow of life energy, movement patterns, the magical signatures of everything happening for kilometers around. Its evolution, forged in London's defeat and honed by the threat of Scathach, allowed it to perceive the battlefield with a clarity that made Chaldea's sensors pale.
"Scanning," its voice resonated in Leonel's mind, a chorus of analytical whispers. "Primary hostile signature count: two thousand three hundred and forty-two, of Celtic origin. Hostile mechanical signature count: eight hundred and seventeen, approaching from the northeast, led by a high-voltage energy signature and... peculiar life configuration. Identification: Thomas Alva Edison."
On Chaldea's screens, Romani let out a whistle of admiration mixed with anxiety. "My god, Leonel! Tezcatlipoca's sensors are giving us data at a resolution we never dreamed of having! It's like you have a magical reconnaissance satellite in your head."
"Confirmed," added Da Vinci, her voice laden with professional fascination. "The data density is astounding. I can see the magical energy hotspots, the troop formations... I can even predict patrol routes with 80% certainty. This changes everything."
Leonel nodded, a cold, calculating smile on his lips. "Edison is coming to strike. Perfect. We're not going to face him. We're going to use him." His plan, devised during the long days of marching, sprang into action.
"Vanguard Squad, positions," he ordered, his voice transmitted telepathically by Tezcatlipoca to the designated recipients.
At the very edge of the battlefield, ready to plunge into the chaos, were Nero Bride and Elizabeth Bathory. Nero Bride, her white dress surprisingly practical for battle, held her sword with lethal elegance. Elizabeth, her heart-shaped microphone transformed into an improvised spear, was visibly excited. "Finally, a stage worthy of my comeback! The audience is on fire!"
Beside her, nearly invisible in the shadows cast by clouds of smoke and dust, was Jeanne Alter. She wasn't part of the official vanguard, but their assassin shadow. "Don't lump me in with your stupid group, Idiot. I'm just here to make sure you don't get killed like rats. And to burn things." Her presence was insurance, an ace in the hole of concentrated fury.
"Vanguard objective," Leonel continued, projecting a shared mental map. "Penetrate the eastern flank during the initial clash. Do not get bogged down in prolonged combat. Your mission is to sow chaos, draw the attention of the Celtic defenders towards you and away from the northwest section of the wall. That's where Geronimo reports the structure is weakest."
In the field, camouflaged among tall grass and debris, Geronimo, the Apache Caster, blended with the land. His spiritual connection to the territory was his greatest weapon. Through Tezcatlipoca's link, his calm voice reached everyone. "Confirmed. The northwest wall is built on an ancient, dry riverbed. The earth is unstable. The roots of trees distorted by the Grail are weakening it further. A concentrated impact point could create a breach."
"Thank you, Geronimo," said Leonel. "Hold position and keep reporting. Billy."
At medium distance, atop a ruined bell tower on the outskirts, Billy the Kid adjusted the sights on his pistol. "Here, boss. Ready and waiting. Give me a target and I'll leave it more holey than a sieve."
"Your target is precision support and distraction. Cover the Vanguard, eliminate any Celt trying to regroup or sound the alarm about their penetration. And when the time comes..." Leonel paused, his eyes fixed on the approaching forces of Edison, "...help guide the main 'distraction' to where it hurts most."
The plan was audacious and depended on perfect timing. Let the two enemy armies—Medb's Celts and Edison's machines—clash head-on. While the bulk of the Celtic forces was busy fighting the mechanical hordes and distracted by the chaos caused by Nero Bride and Elizabeth, the main assault group would infiltrate through the northwest breach. Their target: Medb and the Grail. The premise was that Cu Chulainn Alter, Medb's primary weapon, would be on the front line, busy tearing apart Edison's automatons. Medb, according to Elizabeth's reports and Leonel's knowledge, rarely got her own hands dirty. She was a backstage commander, an instigator who fed on battle and attention, but not a front-line fighter. She would be near Cu, but protected, likely in a high, safe position, cheering on her "champion" like a "glorified simp cheerleader," as Leonel had thought with disdain.
"Everyone understands their roles," said Leonel, his voice one of quiet steel. "Tezcatlipoca will be our eyes and ears. I will coordinate from here. Trust the plan, trust me, and trust each other. The tumor is excised today."
A chorus of mental and verbal affirmations filled the link. Even Nightingale, who was with the main assault group composed of Mordred, Artoria Alter, the original Jeanne, and Leonel himself, issued a, "Disinfection procedure initiated. All instruments must operate with precision."
In the deepest shadows, those not even Tezcatlipoca's expanded radar could fully penetrate, Scathach watched, leaning against the trunk of a charred oak. An almost imperceptible smile of approval curved her lips. The boy wasn't improvising. He was executing. He had studied the field, understood his enemies, and was using their strengths against them. It was the strategy of a true commander, not a warrior. And at this moment, that was what was needed. She would not intervene. This was his field test, his chance to shine with his own light, not that of his Persona. She would watch. And judge.
The first act began with the thunder of artillery. Edison's machines, a line of steel and sparks advancing with heavy determination, opened fire. Lightning cannons fired blue discharges that vaporized groups of Celts. Automatons with spinning saws charged the front lines with mechanical ferocity. At the forefront, the grotesque and powerful figure of Thomas Alva Edison, with his electrified lion's mane and his adorned presidential suit, brandished what looked like a giant megaphone amplifying his voice into metallic commands. "Advance, pillars of industry! Bring the light of civilization to these barbarians! The American dream is an unstoppable assembly line!"
The Celts, far from being intimidated, responded with a collective roar. Warriors in fur armor and war paint rushed to meet them, their swords and axes clashing against metal with deafening clamor. At the heart of the Celtic defense, a bestial figure rose. Cu Chulainn Alter. No longer the blue, light-spear hero, but a mountain of distorted muscles, skin pale as death, and a crown of black thorns. He wielded a monstrous spear, Gáe Bolg, but altered, twisted, dripping corrupt darkness. With a single motion, he swept aside an entire row of automatons, reducing them to molten scrap.
"The hound is busy," murmured Leonel, his eyes fixed on the scene through Tezcatlipoca's shared senses. "Now. Vanguard, go."
Nero Bride and Elizabeth moved. Like two lightning bolts—one white and elegant, the other pink and chaotic—they slipped through a gap forming in the Celtic lines to face the mechanical charge. Elizabeth, with a shriek that was more sonic weapon than song, launched a force wave that cleared a path. Nero Bride, with perfect fencing moves, eliminated any Celt trying to flank them.
"Jeanne, cover their left. There's a group of Celtic archers positioning themselves on that hill," ordered Leonel.
From the shadows, a projectile of black fire whistled and exploded among the archers, sending them flying. There was no confirmation over the link, just the result. Jeanne Alter was doing her job.
The chaos grew. The attention of the Celtic commanders was divided between the enormous frontal threat of Edison and the two swift pests wreaking havoc on their flank. Geronimo's reports came constantly. "Pressure is shifting east. The northwest wall... the guard is thinning. Only a few sentries remain."
"Billy," said Leonel.
In the bell tower, Billy aimed. Two dry shots, almost simultaneous. Two Celtic sentries on the northwest wall fell silently, eliminated before they could raise the alarm.
"Main Assault Group," said Leonel, standing up. His gaze met Mash's, Nero's, Tamamo's, and Kiyohime's. Nightingale, Mordred, and Artoria Alter were already ready, a compact mass of power poised to be unleashed. "It's our time. Through the breach. Objective: the heart of the city. Find Medb. Find the Grail."
With Tezcatlipoca guiding them like a beacon through the sensory chaos, the group moved. They were a battering ram of quality over quantity. Mordred and Artoria Alter cleared the way, shattering any minimal resistance they encountered. Mash protected the flank, her shield deflecting stray arrows or weak spells. The others surrounded them, a lethal personal guard.
As they advanced into the distorted city, the sounds of the main battle faded, replaced by sporadic screams, the creaking of structures, and the omnipresent thump-thump, thump-thump of the Holy Grail. It was a physical sound, a pressure in the chest that guided their path like the worst of radars.
In a central square, where a statue of a historical leader had been toppled and replaced by a grotesque Celtic totem, they encountered their first serious obstacle. A group of elite Celtic warriors, the "Knights of the Red Bronze," surrounded them. They were more organized, stronger.
"Don't stop," ordered Leonel, his mind calculating. "Mordred, Artoria, break their formation with a combined attack on the center. Mash, cover Tamamo. Tamamo, a confusion spell on their rear guard in three, two, one... Now!"
The execution was perfect. A burst of energy from Clarent and the absolute cold of Rhongomyniad broke the front line. As the Celts recovered, a veil of illusory mist and disorientation fell over those in the rear, cutting off their support. In the confusion, Leonel's group passed through like a hot knife through butter, leaving disorganized warriors behind.
Further in, the buildings grew taller, more distorted. American architecture merged with Celtic wood and stone fortifications. And then, from a large building that might have been a library or a museum, a lilting voice, laden with power and manipulative sensuality, rose above the din.
"Oh, my beautiful and fierce Cú! Look at you shredding those metal toys! You are magnificent! The greatest of them all!"
Medb. They couldn't see her yet, but her voice was a direct thread leading to her.
"There," said Leonel, pointing toward the building. His heart beat strongly, but not with fear. With determination. "The Grail is with her. We can feel it."
"The infection is palpable," confirmed Nightingale, her hands clenching into fists. "Pathogen concentration is extreme. We must proceed with immediate excision."
They climbed the cracked marble steps. The main doors, huge and carved from oak, were ajar. From within emanated a corrupt golden light.
Leonel paused on the threshold. He looked at his Servants, his allies, his loved ones. He saw faith in Mash's eyes, fierce love in Kiyohime's, determination in Nero's, lethal serenity in Tamamo's, cold urgency in Nightingale's, and the thirst for battle in Mordred and Artoria Alter.
"This is the moment," he said, his voice a whisper charged with the strength of an entire journey. "For Chaldea. For Humanity. And for our future."
With a gesture, they crossed the threshold. The building's grand hall was transformed into the throne room of a depraved queen. Marble pillars were wrapped in thorny, golden vines. In the center, atop a mound of silk cushions and exotic animal skins, the Holy Grail floated, pulsing like a sick heart. And reclining at its feet, on a throne improvised from the remains of an equestrian statue, was Medb.
She was dazzlingly beautiful, with a dangerous, hungry beauty. Her hair was the color of wine, her green eyes shone with cruel intelligence and insatiable appetite. She wore little, only decorative armor and transparent silks that emphasized her figure and her contempt for modesty. She smiled as she saw them enter, the smile of a predator seeing its next meal arrive.
"My, my... what do we have here? Little mice who have snuck into my parlor? And one of them seems... especially interesting." Her gaze settled on Leonel, scrutinizing him with a lascivious interest that made all the women at his side tense. "The last Master of humanity. I've heard of you. You've caused a lot of trouble. But it doesn't matter..." Her smile widened. "All men end up serving me, one way or another. I'll make you an offer, little Master. Leave me the Grail, join me, and I will give you pleasures that even your little dolls here can't imagine."
Leonel didn't flinch. "I'm not here to negotiate, Medb. I'm here to end this."
Medb's smile faded, replaced by an expression of annoyance. "How boring. Very well. If you want to play war..." She raised her voice. "My fierce wolf! You have guests!"
From a side door, with a crash that shook the floor, Cu Chulainn Alter entered. He wasn't covered in the remains of Edison's machines; he seemed to have left them behind in an instant, drawn by his queen's call. His breathing was a bestial growl, his red eyes glowing with a distorted but lethal intelligence. He dripped darkness, and his mere presence was a declaration of annihilation.
The final battle, the true battle for the Grail and for this Singularity, was about to begin in that hall turned battlefield. Leonel looked at the monster that had once defeated them in London, and then at the Grail pulsing behind the smiling Medb.
"Tezcatlipoca," he said quietly. "All power. All analysis. We underestimate neither of them."
The Persona nodded, its form expanding slightly, emanating an aura of serenity ready for the storm. "All systems operating at maximum. Prepared."
Leonel raised his hand, pointing at Cu Chulainn Alter. "Everyone! The hound first! Separate him from Medb! The Grail is the secondary objective!"
With a collective roar, his Servants charged. Mordred and Artoria Alter lunged at the dark beast, their weapons clashing against the hardened corruption of Gáe Bolg. The lights of the shattered hall flashed with the glare of the final conflict. The plan had worked this far. Now, everything depended on their strength, their will, and the strategic mind that had led them to this room. The battle for E Pluribus Unum had reached its climax.
