They were halfway through the passage when Yui felt it — a pressure change, like the air had tightened around her ribs.
"Haru," she whispered. "Stop."
He did, one hand already reaching back for hers.
The sound came first, a sharp crack, like stone being forced apart from the inside. The tunnel lights flickered, shadows stretching unnaturally long across the walls.
Sayaka dropped from above without ceremony.
She landed hard, boots scraping against the stone, red eyes already narrowed in irritation. Slung across her back wasn't the scythe this time — instead, she held something smaller in her hand. Dense. Metallic. A short, iron rod etched with dull markings that pulsed faintly, like veins under skin.
"Unbelievable," she muttered. "I leave you alone for five minutes and you're already breaking things again."
Haru stepped forward instinctively. "Get away from them."
Sayaka didn't even look impressed. She glanced down at the rod in her hand, thumb brushing over one of the markings.
"This place is unstable enough without you four stomping around in it," she said flatly. "So let's make this easier."
She drove the rod straight into the ground.
The impact rang through the tunnel like a bell struck too hard.
For half a second, nothing happened.
Then the floor answered.
A violent tremor ripped through the passage, the stone beneath their feet splitting along jagged lines that raced outward from where the rod was embedded. The walls groaned, bending inward as if the tunnel itself was being torn at the seams.
"Airi!" Yui shouted.
Kaito lunged forward, grabbing Airi's wrist just as the ground dropped away between them. The crack widened instantly, a deep black fissure yawning open like a mouth.
"Haru—!" Kaito yelled.
Haru shoved Yui behind him, reaching out with his free hand. "Jump!"
The floor lurched again.
The fissure surged upward, stone collapsing inward. A wall of debris slammed down between them with a deafening crash, dust exploding through the air.
Yui screamed Haru's name as the ground gave way beneath her feet.
Haru caught her — barely, momentum dragging them backward as the tunnel split again beneath them.
They slid hard down the collapsing slope, stone tearing free around them as they vanished into the darkness below.
Above, Airi screamed Yui's name, her voice raw with panic.
"Haru! Yui!"
The sound was swallowed by the shifting stone.
Silence rushed in where the tunnel had been.
Sayaka straightened slowly, pulling the rod free from the ground as the markings dimmed. The fissure sealed partially, leaving nothing but rubble and an impassable drop between the two sides.
She exhaled sharply through her nose. "There. Problem divided."
She turned her gaze to Kaito and Airi on the remaining ledge, then down into the darkness where Haru and Yui had fallen.
Airi stiffened immediately, pulling closer to Kaito. "What are you going to do to us?" she demanded, trying to sound braver than she felt.
Sayaka's red eyes flicked over them ,not cruel, not angry. Just tired. Assessing.
"You shouldn't be here," she said flatly. "You both know that now."
Suddenly Sayaka remembered something.
stone walls, cold air, A much quieter Limbo.
The leader stood in front of her, silver hair unmoving, blue eyes sharp as glass. He held out a thin, folded object in his palm — black, matte, impossibly heavy for its size.
"You don't use this unless there is no other option," he said.
"This doesn't place people anywhere," he said. "It removes them from when."
Sayaka frowned. "From Limbo?"
He shook his head once. "From time itself."
He set the folded frame into her palm. It felt wrong there — not heavy, just final.
"It creates a space outside the past, the present, and the future," he continued.
"Nothing inside it can affect time. Nothing inside it can be affected by time."
Her grip tightened. "So they can't change anything."
"No," he said. "They can't interfere. They can't cause damage. They can't be used as leverage by the Watcher or anyone else."
Sayaka frowned. "So…I shouldn't use it much?"
His gaze hardened. "So rarely that you should hate yourself a little if you ever have to."
He closed her fingers around it.
"Only when the alternative is worse."
Sayaka pulled the small black box from her pocket.
The moment it appeared, the air changed. A faint purple aura leaked from its edges, thin and restrained, like pressure barely being held back. The space around it felt hollow — not heavy, not light, just absent.
Airi's instincts screamed.
"Move," she snapped, grabbing Kaito's wrist and yanking him back just as Sayaka raised her arm.
"What is that—" Kaito started.
Sayaka threw it.
The box stopped midair between them, the aura flaring violently as space split open. Not cracked — folded. The inside wasn't dark. It wasn't anything.
The pull hit instantly.
Airi cursed and dug her heels into the stone, nails scraping as she fought against it. "No—!" She twisted, trying to shield Kaito, trying to drag him away.
Kaito reacted on instinct, pulling her back toward him instead, arm wrapping around her as he tried to brace them both. "Airi—hold on!"
The ground beneath their feet cracked. The force was too precise, too absolute, not something you could overpower.
Airi lashed out anyway, striking at the purple light with everything she had. It passed straight through, like hitting the edge of a thought. Her breath hitched as she stumbled forward, fingers slipping from Kaito's sleeve.
"Kaito—!"
He lunged, grabbing her wrist just in time. Their hands locked tight, both of them straining, teeth clenched, refusing to let go even as the pull lifted them off the ground.
Sayaka watched, jaw tight.
"You can't fight this," she said quietly. "That's why it works."
The aura wrapped around them completely now, sound warping, the tunnel stretching unnaturally. Airi tried one last time to pull free, twisting hard enough that her shoulder screamed in protest.
It didn't matter.
The space collapsed inward with a sharp, final snap.
Sayaka stared at the box for half a second longer than necessary.
"…Yeah," she muttered. "That figures."
Yui sucked in a sharp breath instead, fingers digging into the brown dirt and Haru's stomach dropped.
Her lower leg was already swelling, the skin darkening fast into an ugly shade of purple. Even without touching it, he could tell how bad it was. The way she held herself, the way her foot trembled when she tried to move, it wasn't something she could walk off.
"…Okay," he said quietly, more to himself than to her. "Okay."
She nodded, teeth clenched, tears pooling despite her best effort. "It really hurts," she whispered, like she was embarrassed by it.
"I know," he said immediately. "I know."
He didn't ask if she could stand. He didn't suggest trying.
He just slid one arm under her knees, the other behind her back, lifting her carefully. She stiffened at first, then relaxed when she realized he wasn't going to drop her.
She pressed her face briefly into his shoulder, breathing through it.
He started walking.
The tunnel stretched on, narrow and uneven, forcing him to watch every step. His arms ached, his shoulder burned, but he didn't slow down. Every time she shifted, even a little, his grip tightened instinctively, adjusting without a word.
They didn't talk.
Eventually, the passage widened just enough to form a shallow alcove, a break in the stone, barely big enough for two people. Haru stopped, lowering her onto the ledge as gently as he could, and Yui's breathing started to change.
At first it was small, a hitch she tried to swallow down, shoulders tightening like she could physically hold everything in place.
Haru noticed immediately. He glanced over, confused, unsure if he should say something or pretend he hadn't seen it.
Then her face crumpled.
She pressed a hand over her mouth like that might stop it, but the sound broke free anyway — sharp, uneven, ugly.
Tears spilled over before she could wipe them away, her whole body folding in on itself as if she'd finally run out of strength.
Haru froze.
"I—" He shifted awkwardly, hands hovering uselessly between them. "Yui, I—"
She shook her head hard, breath coming in broken gasps.
"I don't— I don't know what to do anymore," she said, words tumbling out between sobs.
"Every plan we make… it just turns into another plan, and then another, and they all fail. It never stops. It's always something."
Her fingers curled into the fabric of her skirt, knuckles white. "Everything's too much. I can't even think straight anymore. I don't know what I'm supposed to do next. I don't know how to fix any of this."
Her voice cracked completely then.
"I miss my parents," she whispered. "I miss Ayumi. I miss when everything was normal. When my biggest problem was being late to school or freaking out about grades or stupid stuff that didn't matter."
Her shoulders shook harder. She tried to keep talking, but the words fell apart, dissolving into quiet, helpless crying. She hunched forward, head bowed, tears dripping onto the stone at her feet.
The tightness in his jaw eased. His expression softened, something fragile and unguarded flickering in his eyes as he took in the way she sat there, breaking under the weight of everything she'd been carrying.
Yui lifted her head slowly.
Her face was blotchy and red, eyes glassy and swollen, lashes clumped together with tears she hadn't bothered wiping away. Her nose was pink, her breathing uneven, like she was still trying to catch up with herself. She looked… small.
Tired in a way that had nothing to do with sleep.
She looked at Haru, really looked at him.
"…What we're doing is wrong," she said hoarsely.
He stiffened, but didn't interrupt.
"Sayaka's right," Yui continued, voice trembling but steady enough to get the words out.
"We're messing with time. With the universe. We're trying to go back and save everyone—save ourselves—stop the Watcher from destroying everything, and we're just… making it worse."
Her hands curled into the fabric of her clothes again. "I know it's wrong. I know it is." Her voice cracked.
"I'm a horrible person."
Haru's mouth opened, but she rushed on, like if she stopped she wouldn't be able to finish.
"I don't want to die," she said quietly. "I don't want the Watcher to kill me. I don't want any of us to die." Her eyes burned as fresh tears spilled over.
She laughed weakly, a broken sound. "What if it's my fault? What if the Watcher found other timelines because of me? Because I kept hopping through them, trying to find him when he was weaker, like that would even work."
She shook her head. "The chances of that are so low. I should've known better. I shouldn't have done any of this."
Her voice dropped to a whisper. "I'm awful."
Haru didn't hesitate.
"You're not a horrible person."
Haru's jaw tightened.
When he spoke again, his voice cracked, just once, like it surprised even him. He didn't cry, but it was close. Too close.
He leaned forward suddenly and pulled her into him.
It wasn't graceful, It wasn't planned. He just wrapped his arms around her and held on, pressing her against his chest like if he didn't, she might slip right through his hands. Yui stiffened for half a second, then melted into it, her forehead resting against his shoulder.
Haru closed his eyes.
For just a moment, he breathed her in, the familiar scent of her hair, warm and real — grounding himself. When he opened his eyes again, they were tired. So tired.
"You're not horrible," he said quietly, voice still rough.
"This whole thing is… complicated. Like—really complicated. Anyone who says they know what the right thing is is lying."
She shook slightly in his arms.
"I don't have a plan," he admitted. "I don't know what we're supposed to do next. I don't even know what Sayaka did to Airi and Kaito."
His grip tightened just a little. "I don't know anything. And I hate that."
He rested his forehead against the side of her head, exhaling slowly. "But none of that makes you a bad person. It just means this is bigger than us."
They stayed like that, the silence settling again — not heavy this time, just quiet. The kind of quiet where neither of them felt like they had to fill it.
Haru pulled back just enough to look at her.
Her eyes were still wet, cheeks flushed, lashes clumped together from crying.
He lifted his hand without really thinking about it, thumb brushing gently along her cheek, wiping away a tear that hadn't fallen yet.
"I don't know how I'd be doing right now if you weren't here."
The words hung between them, fragile and honest.
Yui didn't answer right away.
She leaned forward instead, resting her forehead against his.
Her breath was uneven, still shaky from crying, their noses almost brushing. Haru could feel the warmth of her skin, the way she trembled just a little as she exhaled.
"I…" Her voice broke immediately. She swallowed, trying again, softer this time.
"I love you."
Her lashes fluttered, eyes glassy as she forced the words out through the tightness in her chest. "I love you so much, Haru."
Then a soft, breathless chuckle slipped out of Haru — quiet, disbelieving — and his shoulders shook. He laughed once, barely a sound, as tears welled up and spilled over, tracing slow lines down his cheeks.
"God," he murmured, voice thick. "You really—"
He lifted his hands, careful, like he was afraid of startling her, and slid them gently along her arms.
His thumbs brushed over her sleeves as he leaned closer, hesitation flickering in the small space between them. His forehead stayed pressed to hers for one more heartbeat, eyes closing like he needed the courage.
Then he tilted his head slightly.
Their noses brushed.
Yui's breath caught, her hands tightening faintly in his shirt as he closed the distance the rest of the way.
The kiss was soft ,unsure at first, like they were both figuring it out as they went. His lips pressed against hers, warm and trembling, lingering longer than he meant them to, she kissed him back, just as gently, just as careful.
A tear slipped free from the corner of Yui's eye, rolling down her cheek as she leaned into him, the ache in her chest finally spilling over into something warm instead of crushing.
Haru stayed there with her, lips still against hers.
Haru felt it against his thumb and his chest tightened all over again.
He let out a quiet, uneven breath, his lips still brushing hers as he murmured the words, barely louder than the air between them.
"…I love you too."
