Chapter Text
It had rained overnight. By morning the ground would be a sucking, treacherous mess, every step slower than the last. Mafuyu woke before sunrise anyway. Sleep rarely held him now. The world felt like it was folding inward, tightening around them.
But here—this bed, this warmth—this was the only place he still felt something like happiness. Hiiragi and Ritsuka pressed around him. Shizusumi, too, on the nights he drifted close instead of disappearing into whatever corner he’d claimed for himself.
Here, skin to skin, he could still feel proof of life.
He burrowed closer to Hiiragi, letting his palm drift across his stomach. Six months of running, fighting, rationing had carved definition into the boy he’d once known—lean muscle, sharp lines, cheekbones where softness used to be.
Ritsuka had changed too. The body holding Mafuyu from behind wasn’t bulky—it was forged. Efficient. And now he clung to all three of them like he was personally responsible for keeping them alive.
He had been right.
What would any of them do if the others were gone?
And Shizusumi—steady, quiet Shizusumi—felt the shift most of all. Lately he isolated at night, holing up somewhere in the complex without explanation. A silent retreat Mafuyu didn’t know how to read.
Some mornings he returned with damp hair and dirt on his sleeves. Other mornings, he looked like he hadn’t slept at all—eyes rimmed red, jaw tight, movements too controlled. When Mafuyu tried to catch his gaze, Shizusumi always looked away first. Not out of anger. Out of something heavier.
Mafuyu stared at himself in the mirror: slender, almost fragile. A body too light for the weight he carried. He missed the softness of the old world. He missed the energy of being on stage, the four of them. The crowds. The excitement. But they’d been unprepared back then.
He didn’t notice Hiiragi step behind him until arms wrapped around his torso, palms drifting . “I miss morning sex with you,” Hiiragi murmured. His palms slid down Mafuyu’s torso, slow and grounding to his groin. He wrapped his fingers around Mafuyu’s soft cock, stroking it gently. “You shouldn’t think so hard first thing in the morning.”
Mafuyu leaned back into him—warmth, steadiness, safety, affection.
Shizusumi stood in the doorway, half‑in shadow, unnoticed. He hadn’t meant to stop. He hadn’t meant to watch. But the sight of Hiiragi and Mafuyu, naked, sharing a deeply intimate moment that contrasting sharply with the brutality of their world, rooted him to the spot.
Hiiragi gently stroked Mafuyu’s cock, slow and familiar, and Mafuyu softened under the touch — shoulders loosening, breath easing, the smallest sound escaping him. A private sound. A sound Shizusumi had heard before, years ago, in a different world.
He shouldn’t be seeing this.
He knew he shouldn’t.
But he couldn’t look away.
His gaze tracked the movement of Hiiragi’s fingers, coaxing Mafuyu to erection, the way Mafuyu leaned back into him without hesitation, the way Hiiragi’s mouth brushed Mafuyu’s ear as he murmured something low and intimate. Mafuyu’s lips parted in a tired, helpless smile.
Shizusumi’s breath caught — a tiny, involuntary hitch he swallowed down immediately.
His fingers curled against the doorframe, knuckles whitening.
He looked away for a heartbeat, shame burning hot in his chest.
Then he looked back.
Hiiragi’s thumb stroked a slow circle across the head of Mafuyu’s cock. Mafuyu exhaled, soft and trusting.
Ritsuka had already reached for Mafuyu in his sleep — that instinctive brush of fingers against Mafuyu’s ankle, the unconscious check that he was still there. So when he woke fully and saw Mafuyu naked at the mirror with Hiiragi, also bare, exposed, unashamed, wrapped around him, he didn’t hesitate.
He rose in an instant.
Hiiragi glanced at him but didn’t move away. This was their shape — shifting, overlapping, making space without question.
Ritsuka stepped in behind Hiiragi, close enough that his chest brushed Hiiragi’s back. One hand slid around Hiiragi to Mafuyu’s waist, resting firmly atop Hiiragi's hand. The other settled lightly on Hiiragi’s hip, steadying the whole line of them.
Mafuyu exhaled — a soft, relieved sound — and leaned into both of them at once.
Ritsuka’s voice was low, warm, a little rough with sleep. “I miss morning sex too,” he murmured, not teasing, not heated — just honest, affectionate, familiar. “So don’t go off without me.”
Hiiragi huffed a quiet breath that might’ve been a laugh. Mafuyu’s eyes softened in the mirror, the tension in his shoulders easing under their hands.
Ritsuka pressed his forehead briefly to the back of Hiiragi's head — a small, wordless affirmation of us, of here, of together.
“We don’t have to start the day alone,” he said. “Not anymore.”
Hiiragi’s arms tightened around Mafuyu’s waist in agreement.
For a moment, the three of them stood there — a single, steadying shape reflected in the mirror. Warmth. Contact. A reminder that even in a collapsing world, they still had this.
And in the doorway, Shizusumi watched — not excluded, nor even unwelcome, but hovering at the edge of a gravity he hadn’t yet stepped back into.
Shizusumi felt the moment like a bruise — sharp, blooming, impossible to ignore.
He stood in the doorway, half in shadow, watching the three of them in a shape that belonged to another lifetime. Bare skin, easy closeness, the kind of unthinking intimacy that used to be normal for them. A language they all once spoke without effort.
A language he hadn’t used in months.
Hiiragi’s hands on Mafuyu’s waist.
Ritsuka’s arm sliding around both of them.
Mafuyu softening between them like he remembered how to breathe.
It hit Shizusumi with a force he wasn’t prepared for.
Not jealousy.
Not longing.
Something older.
Something heavier.
Recognition.
This — this warmth, this ease, this unarmored morning — was a whisper of their former life. The last version of them he still understood. Before the creatures. Before the infection. Before he started drifting into corners because he didn’t know how to carry everything he’d seen.
He hadn’t realized how far he’d stepped away until he saw what he’d stepped away from.
His fingers curled against the doorframe, knuckles whitening. He looked away, shame burning hot in his chest — not because he wasn’t welcome, but because he no longer knew how to cross the distance he’d created.
When he looked back, Mafuyu’s eyes were on him.
Just for a heartbeat.
A heartbeat that said I see you.
A heartbeat that said you’re still part of this.
A heartbeat Shizusumi didn’t know how to answer.
He smoothed his expression into something steady, unreadable. But his eyes lingered a beat too long — a beat Mafuyu felt, a beat Hiiragi didn’t miss — before the silence outside pressed in again, reminding him which world he’d been living in lately.
And which one he wasn’t sure he could step back into.
When Mafuyu finally noticed him, Shizusumi’s expression was already smoothed over — calm, steady, unreadable. But his eyes lingered a beat too long.
A beat Mafuyu felt.
A beat Hiiragi didn’t miss.
And then the silence outside pressed in again, heavier than before.
Recognition.
A reminder of everything they’d survived together, and everything they hadn’t said. His gaze flicked to Mafuyu’s injured shoulder, to Hiiragi’s careful hands, to the soft exhale Mafuyu let out as the tension left his body.
Shizusumi’s fingers curled against the doorframe.
He looked away.
Then back.
Hiiragi whispered something low. Mafuyu smiled, small and tired.
Shizusumi swallowed.
And then the silence outside pressed in again, heavier than before.
Ritsuka stirred behind them, half‑awake, reaching instinctively for Mafuyu’s ankle as if checking he was still there. Shizusumi passed through the doorway a moment later, eyes flicking toward the treeline before he looked away again.
Something was wrong.
They all felt it.
Even before they knew why.
The rain stopped by morning, but the air felt wrong—heavy, metallic, like the world was holding its breath.
Mafuyu stepped outside. The rain had left the world washed‑out and colorless, the sky a bruised gray that pressed low over the treeline. Puddles reflected the barricade in warped, trembling shapes. Even the air felt wrong—too still, too heavy, as if sound itself was being swallowed. He rubbed his arms against the chill, but the cold wasn’t what unsettled him. It was the sense that the world was listening. Waiting. Holding its breath for something he couldn’t name.
He wandered just beyond the barricade, the Gibson set gently on the ground behind him. He wasn’t playing. He wasn’t testing.
He was staring.
Across the road, half‑hidden behind a leaning road sign, a creature stood angled toward him. Not approaching. Not retreating. Watching.
Ritsuka spotted him from the gate and froze. “Mafuyu—what the hell are you doing?”
He slipped through the gap in the barricade before he could think better of it. “You’re outside,” he hissed. “Alone.”
Mafuyu didn’t turn. “It’s been there a while.”
Ritsuka moved to his side, pulse hammering. “Why didn’t you call anyone?”
“I didn’t want to startle it.”
Ritsuka swallowed hard. “You’re scaring me.”
Only then did Mafuyu look at him. His eyes were wide, not with fear, but with a terrible, quiet understanding.
“It’s not reacting to sound,” he said. “It’s reacting to me.”
The creature shifted—one slow step sideways, adjusting its angle to keep both of them in view.
Ritsuka grabbed Mafuyu’s wrist. “We’re going back inside. Now.”
Mafuyu didn’t resist. But he didn’t look away from the creature either.
“Ritsuka,” he murmured, “it knew I was coming before I stepped outside.”
Ritsuka tightened his grip. “Then don’t come out here alone again.”
Later, Mafuyu climbed back onto the barricade with the Gibson across his hands, palm muting the strings.
He wasn’t playing.
He was testing.
A soft tap of his finger against the wood.
Tap. Tap‑tap.
Silence.
Then—
A faint rustle from the trees.
Ritsuka stiffened. “They’re reacting to that?”
Mafuyu didn’t answer. He tapped again—different rhythm.
Tap‑tap. Pause. Tap.
This time, the rustle came from a different direction.
Hiiragi’s grip tightened on the tetsubō. “They’re triangulating.”
Mafuyu hummed—low, steady, barely audible.
A shape shifted in the shadows.
Ritsuka swore under his breath. “Okay, stop. Stop—”
Mafuyu stopped.
The shape froze.
Hiiragi exhaled shakily. “They’re not just following sound. They’re… interpreting it.”
Mafuyu plucked a single muted string.
The creature flinched.
Then stepped back.
Ritsuka stared. “What the hell was that?”
“A sustained note,” Mafuyu murmured.
“And that makes them back off?” Hiiragi asked.
“For now.”
---
Julian approached from behind, arms folded. “You’re not afraid of them.”
“Fear doesn’t help,” Mafuyu said.
Julian studied him. “You’re listening to them.”
Mafuyu nodded once.
Julian’s voice dropped. “They’re listening to you.”
Ritsuka bristled. “What’s that supposed to mean?”
Julian didn’t look away from Mafuyu. “He’s communicating. Whether he means to or not.”
Hiiragi muttered, “That’s not comforting.”
“It’s not meant to be,” Julian replied.
---
A shout tore through the compound.
Ayano.
They ran.
Inside the infirmary, the bitten survivor sat upright—barely—eyes glassy, breath ragged. Kurihara hovered beside him, pale and shaking.
“He woke up,” Kurihara said. “Just for a moment.”
Ayano pressed a hand to the man’s forehead. “His fever broke. But the infection—”
The man’s hand twitched violently.
Ayano jerked back.
Dark veins spread along his neck, branching like ink beneath the skin.
Hiiragi swore. “That’s not normal.”
Julian stepped forward, grim. “It’s slower. Mutating.”
Ritsuka’s voice tightened. “Is he turning?”
Ayano didn’t answer.
The man convulsed again, gasping.
Outside, something answered.
A soft, rhythmic tapping.
Matching his breaths.
Mafuyu’s eyes widened. “They’re syncing with him.”
Ayano went white. “We need to sedate him. Now.”
Kurihara scrambled for the kit.
Julian grabbed Ritsuka’s arm. “If he turns, you shoot.”
Ritsuka didn’t argue.
---
The man seized once more—then collapsed, chest rising shallowly.
Ayano injected the sedative. His body went still.
Too still.
Hiiragi whispered, “Is he—”
“No,” Ayano said. “Not yet.”
Julian exhaled. “He will be.”
Mafuyu stepped toward the window.
Outside, the tapping continued.
Not random.
Not creature‑like.
A pattern.
Repeating.
Learning.
“They’re waiting,” Mafuyu whispered.
Ritsuka swallowed hard. “For what?”
Mafuyu didn’t answer.
Because he didn’t know.
But the creatures did.
---
Later, when the camp quieted, Mafuyu returned to the barricade.
He plucked a single sustained note.
Soft.
Steady.
The trees went still.
Then—
A shape emerged.
Not rushing.
Not attacking.
Listening.
Mafuyu’s breath caught.
The creature tilted its head.
Slowly.
Deliberately.
As if recognizing him.
Ritsuka and Hiiragi reached him at the same time, weapons raised.
“Mafuyu—” Ritsuka hissed.
“Back up,” Hiiragi warned.
Mafuyu didn’t move.
The creature didn’t either.
Then—
It stepped back into the trees.
Silent.
Purposeful.
Gone.
Mafuyu lowered his hand.
“They’re not hunting us,” he said softly.
Ritsuka stared. “Then what are they doing?”
Mafuyu looked toward the distant city.
“Learning."
Shizusumi hung back from the barricade, far enough that none of them had to step around him, close enough to see the way Mafuyu’s shoulders eased when the creature disappeared into the trees. Ritsuka and Hiiragi flanked Mafuyu without thinking, their shapes closing in around him the way they always did.
It was the same gravity as that morning, pulled into a different orbit.
Shizusumi felt the echo of it like a bruise and stayed where he was, just outside the line they made. Watching.
Not excluded.
Not stepping in.
