The ambient hum of the LDS Command Room was subdued, swallowed by an unnatural stillness. On the central monitors, the tactical heatmaps of Maiami City's transit grids flickered once before vanishing entirely, replaced by Reiji Akaba's newly calibrated tracking network.
Nakajima stared at the screen, his collar suddenly feeling a little too tight as five distinct glowing signatures stabilized across the vast, wireframe map.
"President... setting the network to track specific individuals instead of sector heatmaps—if they scatter into crowded zones, our visual feeds will lose them."
"They won't scatter randomly," Reiji said, his voice flat, devoid of theatricality. He didn't look back; his hands remained loosely crossed behind his waist, his thumb methodically pressing against his knuckles in a quiet, unconscious rhythm. "An army operates on logistics. Infiltrators operate on intent."
He tapped a single key, isolating the junction where the soldier had vanished.
"The Acadmia operative did not engage Ryo to secure a tactical footprint," Reiji continued. "He engaged to buy time."
"To cover the girl's retreat," Nakajima muttered.
"They revealed one move," Reiji corrected. He swept his hand across the glass, re-anchoring the surveillance network not to physical streets, but to probability nodes anchored to five specific individuals. "Which means this move exists to conceal the next. We do not need to sweep every alleyway. We track priorities."
Nakajima exhaled, nodding as he turned back to his console to relay the search parameters.
Reiji stood alone before the towering glass floor-to-ceiling display. His glasses caught the stark blue reflection of the wireframe city, casting his eyes into shadow.
His model was precise. His probabilities were sound.
Yet, as the blue nodes pulsed softly on the screen, a microscopic variable quietly lingered at the back of his mind—one he had deliberately excluded from the algorithms. He had calculated intent, Leo's strategic timeline, and Celina's high-value.
He had not calculated what happens when a weapon begins to feel.
Reiji's fingers tightened slightly against his sleeve. He adjusted his glasses, burying the thought beneath a fresh layer of data. "Emotion is a secondary symptom. It does not alter vectors."
# Stadium
In the quiet lower concourse near Stadium No. 2, the roar of the crowd felt distant, muffled by layers of heavy concrete.
Yuya Sakaki stood near the shadow of the participant tunnel, his knees slightly bent, leaning his back heavily against the cold tile wall. His breathing was uneven. His fingers trembled as he pulled his deck from its hip holster, fumbling slightly before sliding out Dark Rebellion Xyz Dragon.
He drew the card up to his chest, staring down at its dark, jagged artwork.
During the duel, when the dragon had burst onto the field, Yuya had felt a violent, suffocating rage—a phantom heat that wasn't his own, screaming for vengeance. It had frightened him, but it had felt alive.
Now, as his bare thumb brushed the card's matte surface, he felt... nothing.
No pulse. No lingering warmth. A complete, terrifying, hollow silence.
Yuya's breath hitched. He picked at the corner of the card's sleeve with his thumbnail, pressing down harder, desperate to spark even a flicker of that phantom energy. Nothing. The dragon was just ink and foil.
"Why...?" He whispered, his voice cracking slightly in the empty hallway. "Are you gone? Or... are you disgusted with me?"
He squeezed his eyes shut, pressing the card against his forehead. He was supposed to bring smiles. He was supposed to use this power to save people, the way his father would. He still wants to. But he don't know how. But he knows he will.
"Yuya!"
Yuzu's voice bounded off the concrete walls.
Yuya jumped, nearly dropping the card. He hastily jammed Dark Rebellion into his pocket—not into his deck, but into his jacket, hiding it close to his ribs—as Yuzu stepped out from the main arena floor. Her face flushed with the exhilaration of her victory. Her duel disk was still powered on, humming quietly as it vented faint wisps of hot air from its Solid Vision emitters.
"You were... amazing out there, Yuzu," Yuya stammered, offering a smile that didn't quite reach his eyes. "The crowd went crazy."
Yuzu lowered her head, her bright expression slowing to a stop. She knew that smile. She had seen him wear it every time he was trying to hide a bruised knee or a broken spirit when they were kids.
"Yuya," she said softly, taking a step toward him. "Your hands are trembling."
Yuya swallowed hard, quickly shoving both hands deep into his pockets. "I'm..." He caught himself, his lower lip trembling for a fraction of a second before he forced a breathless laugh. "...I'm just hyped up, you know? Seeing you win like that... I gotta step up my game for the next round."
Yuzu watched him quietly, the hum of her duel disk filling the silence between them. She wanted to push. She wanted to grab him by his collar and force him to tell her what happened in that dark alleyway two nights ago.
Instead, she offered a soft, gentle nudge with her elbow against his shoulder. "Don't get cocky. You still have to keep up with me."
"Yeah," Yuya murmured, looking down at shoes. "Yeah, I know."
He turned back toward the dark exit corridor. Somewhere far away, another decision had already been made for him.
# Somewhere else
Miles away, beneath the sprawling industrial sector, Vance navigated the damp side streets with a short, rapid stride. Beside him, the boy in the white jacket scrambled to keep pace, his rubber-soled shoes squeaking awkwardly against the wet asphalt.
Vance didn't slow down, but his jaw clenched. High above the rusted roofs, a sharp thrum-thrum-thrum echoed through the overcast sky.
Three high-altitude LDS surveillance drones, which had been sweeping in wide, lazy search grids across the district just five minutes prior, suddenly snapped their rotors. They tilted hard, their red optical lenses refocusing into sharp, narrow beams as they streamlined into direct, targeted flight vectors.
Vance stopped dead in his tracks. He grabbed the boy by the shoulder of his white jacket and yanked him back under the rusted overhang of a closed freight warehouse.
"Hey! What gives—" the boy started, stumbling over a loose brick.
"Shut up," Vance snapped, his voice a sharp, harsh rasp.
He didn't look at the sky. He looked at the street ahead. The drones weren't searching the blocks anymore. They weren't hunting locations. They were tracking movement signatures.
"They adapted," Vance realized, a sour taste coating his tongue. "Akaba stopped looking at areas and started hunting the rats."
BZZT.
The single, muted vibration against his ribs made him wince. Vance pulled out the small, cheap burner comm receiver, slid it open with his thumb, and squinted at the single line of text.
OBSERVE.
Vance let out a quiet, bitter breath through his nose. He hated the suit-and-tie. One just sat in clean, air-conditioned rooms telling field assets to "observe" while the sky was crawling with eye-bots.
He snapped the burner in half, tossed the pieces into a puddle of oily water, and unzipped his outer windbreaker. He shoved it violently into an open industrial dump bin.
"Take off the white jacket," Vance ordered, pulling a dark, fraying cap low over his forehead.
The boy blinked, clutching his sleeves. "What? No! It's cold out here, and besides—"
"Take it off or I leave you on this curb for LDS to haul into a cell," Vance growled, leaning in close. "They aren't sweeping streets anymore. They're tracking us. Put that black shirt on over your white jacket."
The boy trembled, biting his lip before hastily stripping off the bright white jacket and shaving it under his black undershirt in the cold.
Vance grabbed him by the elbow, turning them sharply down a narrow, trash-strewn alley. "Keep your hands dormant. We move on foot, under the overhangs."
# Time Passed — LDS Headquarters
The digital display mounted on the wall of the LDS Command Room flickered, updating the live bracket calculations. Reiji Akaba stood before it, his reflection cast pale against the glowing numbers.
He didn't track the entire list. His eyes rested briefly on the lowest tier of the bracket—where Yuya Sakaki's name sat.
The final name locked into place. No more simulations remained.
He turned on his heel, leaving the hum of the servers behind as he walked toward the primary executive office.
Tomorrow had become inevitable.
# Youshow
Across the district, the heavy iron doors of Youshow Duel School were pulled wide, welcoming the cool night air. Inside, the warm, orange light of sunset washed over the wooden floorboards, accompanied by the chaotic clatter of plates, the hum of an old refrigerator, and cheerful voices.
"I still can't believe it!" Futoshi cheered, slamming his hands onto the table while stuffing half a dumpling into his cheek. "All three of you! Yuya-niichan, Yuzu-neechan, and Gongenzaka! You all made it through!"
Yoko flicked Futoshi's forehead as she passed by, carrying a massive platter of sandwiches. "Chew first, Futoshi."
"Though he's right—you three worked incredibly hard," Shuzo boomed, leaning over the table with a proud grin.
Gongenzaka sat without a word, crossing his arms with a modest nod, resting his gaze on his teacup.
"Cheers to that!" Shuzo added, raising a glass of juice. "To the pride of Youdhow!"
Yuya sat near the edge of the table, smiling as he picked at his food with his chopsticks. The laughter around him was familiar and comforting, a stark contrast to the overwhelming tension that had consumed Maiami City over the past few days.
Suddenly, the TV on the wall chimed. The local broadcast cut directly to Nico Smiley, holding a microphone in the center of an empty arena, his voice crackling slightly through the small speakers of TV.
"Attention all citizens and duel fans! The results for the second round of the Maiami Championship are officially locked in! The full list of qualifiers advancing to tomorrow's third round is now live on your screens!"
Ayu, Tatsuya, and Futoshi leaned in close to the monitor as the names began scrolling down.
"Look! There's Gongenzaka!" Ayu pointed.
"And Yuzu-neechan! And Yuya-niichan!" Tatsuya added, clapping his hands.
The list continued to scroll, ticking off the names of top-tier duelists from LDS, independent entries, and local schools. Then, a single name flashed at the bottom of the qualified bracket:
SHUN KUROSAKI
The laughter in the room died instantly.
The air grew heavy. Tatsuya lowered his hands. Futoshi stopped chewing.
"Kurosaki..." Tatsuya whispered, his voice laced with sudden resentment.
"Ever since he came..." Ayu murmured, her fingers clutching the edge of her skirt, her eyes fixed on the display. "Everything's gone wrong. Sora wouldn't have gone after him if he hadn't attacked him!"
"We still don't even know where Sora is!" Futoshi yelled, his face flushing red.
"Enough," Gongenzaka said softly, holding up a single hand.
Yuya hadn't spoken. He looked down at his reflection in the glass of water sitting on the table.
"You're wrong," Yuya said.
The room went quiet. Everyone turned toward him.
"Yuya?" Yuzu asked gently.
Yuya lifted his head. His eyes weren't filled with anger, but with a quiet clarity that caught everyone off guard.
"Shun didn't make Sora disappear," Yuya said, his voice barely above a whisper. He looked toward the window, where the last rays of sunlight were slipping beneath the horizon. "Sora had to leave."
A silence settled over the room. Ayu looked down at her shoes. Tatsuya swallowed hard.
"We don't fully understand what's happening out there yet," Yuya continued, standing up from his seat. "We don't know what Sora was fighting for, or what Shun went through. But blaming Shun won't bring Sora back." He looked at Yuzu, then at his mother and Shuzo. "I'll do whatever it takes to bring him home. With my entertainment duel!"
Shuzo looked at Yuya for a long moment, the theatrical coach giving way to a proud mentor figure. He reached out, rustling Yuya's hair with a gentle, steady grip.
"Then bring him home," Shuzo said softly. A warm smile broke across his face as he patted Yuya's shoulder. "But first... finish your dinner."
People began eating again, but nobody laughed as loudly as before. The quiet remained, heavy and persistent.
...
While Youshow clung to the warmth of an momentous evening, another group spent the same sunset preparing for war.
Miles away, high above the streets, that same quiet pressed against the floor-to-ceiling glass of the LDS Executive Office, broken only by the distant hum of traffic far below.
Himika stood near the window, looking down at the sprawling, oblivious city lights. Ryo stood near the center of the room, delivering his report to Reiji, who sat behind his desk with his fingers laced together.
"The reports from the perimeter scouts are consistent," Ryo stated calmly. "The dimensional energy signatures remain scattered around the outer sectors. If that Academia operative transmitted a signal before fleeing, an invasion force could arrive at any moment."
"Tomorrow," Himika said without turning around. "The eyes of the entire city will be on the championship. LDS has evaluated duelists for years... tomorrow, the enemy will help us."
"If Academia strikes during a live broadcast, panic will sweep the district," Ryo said. "What is your plan, Reiji? Do we cancel the public broadcasts?"
Reiji didn't answer with words. His finger tapped a single key on his terminal desk.
A massive holographic grid erupted in the center of the room, rendering a three-dimensional topographic map of Maiami City. The central district flashed in bright, glowing green, expanding outward block by block.
"Tomorrow's arena," Reiji said. "Maiami."
Ryo studied the map as the grid encompassed roads, parks, and residential sectors. "...You're turning the city into arena."
"And the civilians?" Ryo asked, his voice dropping an octave
"This will be a battle royal," Reiji said. "We will make the entry for this free. More people will come from city, and it will help. All duels will be displayed on all the screens of all Stadiums."
"If Academia will actually strike while the battle royal is going, what then?"
"We will cut off the screen on any time a Academia fight happens. Spectors will not like it, but it is necessary to not make uproar during duels."
"The candidates? If they fall... if they are carded?"
"Every victory has a cost," Reiji stated, his expression unreadable behind the glare of his glasses.
Ryo met Reiji's gaze, the tension stretching taut between them. "And if your projection is wrong?"
Reiji didn't flinch. "Then we all lose."
"But no one will not be saved from being carded."
"Only if they are not strong. If they are then nothing is to fear. We want strong duelists who can defeat Acadmia forces in the first place."
Ryo blinked. No footsteps had echoed across the marble floor; no door had opened. When his eyes focused again, two figures were standing beside Reiji's desk.
They were simply there, rooted to the spot like shadows taking form.
One possessed sharp dark blue hair and lazy blue eyes; the other had striking red hair and deep, dark eyes. Both stood perfectly upright, as motionless as stone.
"Tsukikage. Hikage," Reiji introduced simply. "Ninjas of the Fuma clan. Their primary objective is to monitor the candidates and protect a specific target. Celina."
"You're leaving her loose?" Ryo asked. "Leaving her to wander the city is reckless."
"Freedom is easier to predict than captivity," Reiji replied smoothly, bringing up a secondary window showing a live video feed.
The camera zoomed in on a young girl standing near the perimeter fence of the empty central stadium. Her indigo hair was tied up, her arms crossed tight over her chest, watching the dark arena with burning resolve.
"She has nowhere else to go." Ryo said. "What about Kurosaki Shun?"
Reiji added. "And as for Shun Kurosaki... his rage is a tool that requires no maintenance. He will fight Academia regardless of our commands."
Reiji closed the display.
The office fell silent.
# Park
While the high-rises planned for war, the city's quietest corner remained untouched by their calculations.
In an overgrown park in Sector 4 of the city, a single streetlight flickered softly over a bench. High above, a distant train horn echoed faintly through the night air, lost in the rustle of dry leaves and the soft chirp of night crickets.
Vance sat on the bench, his back straight, his eyes closed. Beside him, the mysterious boy slumped slightly against the slats, deep exhaustion finally dragging him under.
He drifted.
The high-pitched roar of a engine, riding an motorbike, wind tearing past his ears as warm arms locked tightly around his waist from behind.
A birthday cake, lit candles reflecting in a window.
A page turned in the dark.
Blood on white snow, vanishing into red mud.
Half a photograph, the paper yellowed and torn.
A classroom full of empty desks.
Missing faces, erased by streaks of black ash.
Another page turned.
A hand reaching out into the rain, holding a card that burned with a faint, crimson light.
The boy stirred in his sleep, a faint breath escaping his lips, but he did not wake. Beside him, Vance opened one eye, glanced at the sleeping boy, and closed it again, letting the darkness hold them.
# Academia
Across the dimension, there was no quiet.
The air inside the throne chamber of Academia was freezing, thick with the smell of cold steel, punctuated by the rhythmic, heavy clanking of automated machinery in the depths below.
Dozens of high-ranking commanders and elite officers stood in strict formation along the polished stone aisle. Among them stood rows of Obelisk Force soldiers clad in blue-and-white uniform, their faces obscured by helmets bearing dark red lenses. They stood like statues.
Standing slightly behind the front line of officers, Commander Barret scanned the ranks with a sharp, disciplined eye. He noted the empty space near the secondary dais. "Commander Phoenix... Edo remains absent," Barret thought, his gaze returning to the throne.
At the center of the lower platform stood Sora Shiunin in a rigid military posture, his head bowed.
At the top of the stairs, sitting upon a massive throne, was Leo Akaba.
"The time for preparation has passed," Leo's voice boomed, echoing off the high stone walls. "Tomorrow, the Standard Dimension will learn the reach of Academia."
He gestured faintly. A large holographic projection materialized in the center of the hall, displaying Celina's 3D image.
Sora's eyes flicked upward. His breath caught in his throat.
"Yuzu...? No... Celina."
His expression hardened instantly, burying the reaction before anyone could notice.
"Recover Celina," Leo commanded, his voice cold and absolute. "Nothing supersedes this command."
The throne creaked faintly as Leo rose, sweeping his arm forward with absolute authority.
"But the second objective is to carding the people remains. Recovering Celina back is main priority above all. But whoever inhabitant of Standard Dimension comes in your way or whoever tries to stop you, you all know what to do.
"With this deployment, the Arc Area Project advances to its next stage," Leo announced.
In perfect unison, every officer and Obelisk Force soldier slammed their right fist over their chest in a crisp, military salute.
"For the Paradise!" They roared in unison.
Leo looked down at his assembled army, his focus fixed on what lay beyond the wall behind him and his throne.
"Paradise... begins."
Silence reclaimed the throne room as the soldiers held their salute.
And somewhere beyond Academia, hidden within the dark corridors of the staging bays, the first transport gate began to charge.
It would be ready by sunrise.
