Haru and Yui stumbled to their knees as the world shifted around them, the dizzying pull of the clock finally fading. The air smelled faintly of rain and grass, softer than the metallic tang of the castle they'd just escaped.
Haru's chest heaved, adrenaline still thrumming through his veins. Yui clung to his arm, both for comfort and to steady herself — the sudden change in reality made the ground feel unsteady beneath their feet.
"Where… are we?" Yui whispered, eyes scanning the scene. Everything looked familiar, but nothing matched exactly. The streets were quieter, the buildings smaller, and the sunlight had a gentler hue. It was like seeing a memory through a fog.
Haru shook his head slowly, crouching low. "I… I don't know. Maybe… some kind of other universe? Or… a different timeline? I can't tell."
They crept forward, keeping low to the shadows, when movement caught their eyes. A group of their friends was up ahead — Kaito and Airi among them, talking quietly, Daichi laughing at something small.
Everything was the same as they remembered, down to the way Kaito fidgeted with his sleeve and the way Airi tucked her hair behind her ear.
And then Yui froze. "Haru… look…"
From around a corner, Haru and Yui themselves appeared — their own recent selves, unaware of the events that had already happened. The realization hit them like a punch.
Haru's jaw tightened. "We… we went back in time. Not far, but… far enough." His voice was low, tense. "This… this is before everything started going wrong."
The familiar hum of arcade machines buzzed through the air, broken up by the sound of laughter and the faint melody of old game themes. The place hadn't changed — the flashing lights, the sticky floors, the smell of popcorn and soda — it was all exactly as Yui remembered.
Haru and Yui stood in the corner, half-hidden behind a claw machine. Their hearts pounded in sync as they watched their past selves and friends scattered around the room, laughing and teasing each other like nothing in the world could go wrong.
The sight hit Yui like a knife — the weight of what they'd lost, and what they could still lose, pressed hard on her chest. Haru noticed her expression and subtly brushed his fingers against hers, grounding her.
But then Kaito's head tilted slightly. His brow furrowed. He glanced around, eyes narrowing — that subtle, instinctive alertness that always made him stand out.
"Someone's here," Kaito muttered, his voice quiet but sharp.
Airi blinked. "What?"
"Just—wait." He stepped slightly in front of her, eyes sweeping the arcade again. His hand instinctively reached for hers, pulling her a little closer.
Yui stiffened. "Haru—he sees us," she whispered, panic bubbling in her chest.
"Stay down," Haru hissed, tugging her behind a machine covered in flashing blue lights.
They crouched low, hearts hammering. The floor buzzed faintly with the vibration of nearby music games.
Kaito's gaze lingered in their direction, his expression unreadable.
The light from the machines caught the faint shimmer in his eyes — that subtle glint that always made him seem more aware of the unseen.
"I swear I saw something," he murmured to Airi.
"Probably just your imagination," she replied lightly, though she didn't sound convinced.
He didn't respond — just kept scanning.
Yui squeezed Haru's sleeve tightly, her breath uneven. "He's too observant… he'll find us…"
The arcade buzzed with energy — flashing neon lights, the scent of buttered popcorn, and the hum of overlapping game sounds. Yui and Haru pressed themselves against the side of a claw machine, peeking out just enough to see their past selves laughing with Ayumi, Haruka, Airi, Kaito, and Daichi near the racing games.
The sight was surreal — like watching ghosts that didn't know they were already dead.
Haru's throat tightened. "I remember this day," he whispered.
"It was during the weekend I think, we were all hanging out at the arcade.."
Yui nodded, eyes wide, heart hammering. "Then… we really did go back," she murmured. "But if we're here, then—"
"—we can't be seen," Haru finished, scanning the crowd.
They began to move carefully, keeping low, weaving through groups of teenagers clustered around fighting games and prize counters.
The pounding bass from a rhythm machine masked their footsteps, colorful lights flashed across Yui's face as she glanced around anxiously.
"Stay close," Haru whispered, tugging her behind a couple who were arguing over tokens.
They ducked past another row of machines — but then the music changed, rising in volume, the sudden roar of a victory jingle echoing across the room.
Yui froze. The flashing lights from the racing booth lit up their faces for just a second — long enough for someone to notice.
"…Yui?"
The voice came from behind them.
Yui's blood ran cold. Slowly, she turned.
Kaito stood there, a prize ticket half-crumpled in his hand, confusion painted across his face.
His eyes darted past them toward the other end of the arcade — where the other Haru and Yui were still laughing with their friends.
His expression faltered.
His breath hitched. "W-what—" He looked between the two Yuis, two Harus, disbelief flooding his voice. "How—how is that—?"
Haru stepped forward slightly, his body tense.
"Kaito, listen—"
But Kaito shook his head, his voice trembling. "You're… you're here, but you're also there. What are you?"
His brows drew together.
Quietly, almost to himself, he said, "…That's impossible."
Before he could take a step closer, a voice called out behind him.
"Kaito!"
He turned just as Airi jogged up to him, holding a token card and looking unusually frustrated. "I need help," she said quickly, brushing a strand of hair from her face.
"And before you say anything, no, I wouldn't normally ask you—but everyone else, it would take up to much time trying to explain this to them.."
Her tone was clipped but tired, her usual confidence tinged with annoyance. Kaito blinked, caught off guard but ready to respond. "What do you—"
Then she saw where he was looking.
Her words trailed off as her gaze followed his—past him—toward the two shadows near the claw machine.
Two figures.
Two very familiar faces.
Her grip on the token card loosened. "…What—"
The noise of the arcade swelled suddenly, drowning out her voice. Lights flashed overhead, machines blinked erratically, and for a split second, it was as if time hiccuped.
Airi's token card slipped slightly from her grasp.
Her eyes followed Kaito's again, then past him, toward the other end of the arcade. Her voice barely rose above the din of the machines. "…That can't be… It's impossible."
Haru exhaled slowly, jaw still tight. He leaned closer to Yui, murmuring softly, "We have to get out of here… quietly."
Yui nodded, her hands tightening just a fraction more around his arm. But neither of them moved forward—not yet. Not while Kaito and Airi's confusion hung so thickly in the air. Every step had to be measured, every breath controlled.
One wrong move and the delicate veil separating past and present could tear entirely.
The arcade's lights flickered again, and for a split second, it felt like the world itself was holding its breath.
Haru's grip tightened on Yui's hand. His voice was sharp but low, urgent.
"Yui… we gotta run. Now."
Yui barely had time to nod before he yanked her forward, sprinting toward the arcade exit. The noise of the machines and the scattered crowd swallowed their footsteps, but it wasn't enough to hide the pounding of their hearts.
Every instinct screamed at them to keep moving, to not look back.
Behind them, Kaito's gray eyes widened. Without thinking, he reached out and grabbed Airi's hand, his fingers curling around hers just like instinct demanded.
She yelped, startled, but didn't resist. In fact, there was a flicker of something shy and unsure in her gaze as he tugged her forward.
"Wait! K-Kaito, what—?" she started, but he shook his head, voice tense, almost breathless.
"Just—come on!"
The two of them wove through the crowd, Kaito half-dragging her, half-running to keep up with the fleeing figures ahead.
Airi's free hand clutched the token card, but her attention was on Kaito — and on the strange, impossible sight in front of them.
By the time they reached the street outside, Kaito slowed slightly, trying to catch his breath.
His eyes darted between the fleeing Haru and Yui, then back to Airi. Confusion and worry clashed across his face.
"What… what is going on?!" he demanded, gray eyes wide and sharp. "Who are they? How—how is this even possible?"
Airi's brow furrowed, frustration and panic mixing into a strange helplessness.
She swallowed hard, trying to make sense of what she was seeing, but her words caught in her throat.
"I—I don't know!" she admitted, her voice small, uncharacteristically lost. "I… I don't understand any of this!"
Kaito tightened his hold on her hand reflexively. "Then help me figure it out. Just… stay close."
Airi nodded, letting herself be guided by him. Her usual confident composure was gone, replaced by the weight of pure confusion—and yet, in that moment, her small grip on his hand was a tether, grounding them both amidst the chaos.
Ahead, Haru and Yui didn't slow, their steps quick and desperate, but a glance back told them they weren't alone — Kaito and Airi were keeping pace, following them into the unknown.
Haru and Yui ducked into the quiet corner of the alley, the glow of neon spilling over cracked pavement. Their breaths came in short, rapid bursts, hearts hammering in tandem.
Ahead of them, Kaito and Airi had slowed, watching, confusion written clearly across their faces.
Haru exhaled, forcing himself to meet Kaito's gray eyes. "Listen… this is going to sound impossible. But we're from the future."
Kaito's brows drew together. "The… future?"
His voice trembled slightly, a mixture of disbelief and something sharper — worry.
Yui took a small step forward, her voice barely above a whisper.
"We've been traveling through different universes. Trying to… fix things." She swallowed hard, hands twisting the strap of her bag. "Everyone dies in the future..and Daichi… we don't know if he's alive anymore."
Airi's grip on her token card tightened. "Everyone dies? Daichi? What are you talking about?"
Haru continued, his voice calm but urgent. "Right now, we're trying to get back to our time — to reverse the Watcher's timeline when he was weaker and… stop him. We don't know if it'll work. We don't know if Kaito survives in the future, and we… we don't know how to fix everything."
Kaito's gray eyes widened, searching Haru's face. "You… you've been trying to change fate?"
"Yes," Yui said, her voice shaking a little. "We know things can't be undone easily. But… we can't stop trying. "
Airi swallowed, her usual confidence faltering. She looked at Kaito, whose grip on her hand had tightened reflexively. "You've… been carrying all of this?" she asked, voice small.
Haru nodded, shoulders tense. "We don't have a choice anymore. We need help… if we're going to have any chance."
Kaito blinked, swallowing hard. Gray eyes flicking between Haru, Yui, and Airi.
"I… don't know what to say." He let go of her hand slightly, then tightened it again, instinctively.
"But… we'll listen. Tell us everything."
Yui looked at them, earnest and pleading.
"Please… just hear us out."
Airi hesitated, then gave a small nod, fingers squeezing Kaito's hand. "Okay… but we do this smart. No risks we can't handle."
Haru gave a grim smile. "Agreed."
Sayaka barely had time to steady herself when the air shifted again.
The limbo darkened, flattening under a sudden, crushing presence. The silver-haired man stepped forward, blue eyes cold and unblinking as they fixed on her.
"…You lost them," he said.
Sayaka clicked her tongue, wiping a smear of blood from the corner of her mouth. "They got lucky."
"Lucky?" His gaze flicked briefly toward the direction Yui and the others had fled, then snapped back to her. "They are children, Sayaka. And you've let them slip away how many times now?"
Her jaw tightened.
"You dragged them through the past," he continued, voice calm but edged with warning. "You allowed fractures to deepen. You let them reach deeper limbo."
" Don't make me regret taking you in that day."
For a split second, Sayaka didn't answer.
The gray around them blurred, replaced by something much older in her mind — a cracked street, blood on her hands, a voice telling her to survive or disappear. Cold. Alone. Small.
Her fingers curled slowly into a fist.
"…I won't," she said quietly.
The leader studied her for a long moment, then turned away. "See that you don't."
Sayaka straightened, forcing the memory down, red eyes burning with something sharper than anger now. "Next time," she muttered under her breath, "they won't run."
——————-
Daichi didn't remember the last time the sky had been normal.
Above him, it churned endlessly — not clouds, not smoke, but something in between, like the world itself was rotting from the inside out.
Buildings bled into one another, streets folding where they shouldn't, lampposts flickering with a sickly green light.
The living world and the limbo had collapsed together here, tangled so tightly there was no separating them anymore.
Every step hurt.
Daichi staggered forward, one hand pressed hard against his side. Blood soaked through his fingers, warm and slick, dripping onto cracked pavement that pulsed faintly beneath him.
His breath came in shallow gasps, vision blurring at the edges.
Don't stop. If you stop, you die.
A shrill screech echoed down the street.
Daichi froze.
A spirit crawled out from between two fused buildings — its shape wrong, stretched, its limbs bending in places limbs shouldn't bend. Its face flickered between human and something hollow, empty-eyed.
"Shit…" Daichi muttered, forcing himself upright.
He raised his weapon with trembling hands, pain screaming through his body as he swung. The blow connected, barely — enough to send the thing shrieking back into the shadows, but not enough to kill it. He stumbled, nearly collapsing as another wave of dizziness hit.
He couldn't afford this. Not here.
This universe was wrong. The Watcher had passed through it — he could feel it, like a pressure behind his eyes, like the air itself was watching him back.
The thing didn't stay in one place anymore. It moved.
Hunted.
And Daichi knew why.
He's looking for them.
The thought made his chest tighten painfully. Yui. Haru. Were they alive? Were they hiding like he was, slipping through broken worlds and hoping not to be noticed?
A low, familiar hum crept through the air.
Daichi's blood ran cold.
He ducked into the shell of a convenience store just as the hum deepened — the sound of time bending, reality tightening like a noose.
Through the shattered window, he caught a glimpse of something tall and still at the end of the street, it was The Watcher.
It didn't rush. It never did. It simply existed, emerald light pulsing faintly, patient and certain. It didn't need to chase prey in a world like this.
Daichi pressed his back against the wall, biting down hard to keep from gasping as pain flared in his side. His hands shook, slick with blood, his strength fading fast.
If it finds me…
He swallowed hard, forcing his thoughts forward. Then I run. Or I die buying time.
A spirit skittered across the ceiling above him, unseen but heard. Another screech echoed somewhere too close for comfort.
Daichi closed his eyes for just a second.
"I'm still here," he whispered, to no one and everyone. "I'm not dead yet."
Outside, the hum grew louder.
And somewhere across the fractured multiverse, the threads were pulling tight — drawing all of them back toward each other, whether they were ready or not.
