Claval’s departure did not end the scene so much as it left a bruise behind.

  The guild hall was still the same wide room of stone and wood, still lit by hanging lamps and crowded tables, still full of people who had come to trade coin for risk. Yet the noise that usually lived here—boots scuffing over grit, chairs scraping, the layered hum of voices—had thinned into something cautious. It would return, eventually. It always did. But for the moment, the air carried a brittle aftertaste, like soot you couldn’t see but could still smell.

  Rize stood where she had been left, breathing in shallow pulls that did not quite satisfy her lungs. The pain in her chest was gritty, as if the pressure of Claval’s grip had turned into sand and lodged itself between ribs. Even when she swallowed, the motion felt wrong, her throat tightening as if it still remembered being held. Cold.

  That was the part that refused to fade. Not just the strength—though that too had been undeniable—but the temperature. Claval’s hand had not felt like a living person’s hand. It had been cool and precise, like polished metal pressed to skin, and the thought of it made Rize’s pulse flare in spite of herself.

  Around her, people pretended to resume their business. A clerk began sorting papers again. A pair of adventurers leaned toward one another and spoke in low voices. Somewhere, someone laughed too loudly, trying to punch a hole through the silence.

  Rize exhaled, and the breath left her mouth in a thin line. She was only aware of her own heartbeat—too loud, too fast—until a sharp sound snapped her attention sideways.

  Roa shut her documents with a crisp, irritated snap, as if the paper itself had offended her. When she looked at Rize, her gaze was clear and steady, the kind that didn’t soften out of pity.

  “She might come again,” Roa muttered. Rize didn’t answer right away. The idea slid under her skin with nasty ease, because it didn’t feel like a prediction. It felt like a statement of fact.

  “No,” Roa’s fingers remained on the folder, knuckles pale. “Next time she might appear in the middle of a request.” she corrected herself, voice tightening.

  “She’s a fellow adventurer, right? To pull something like that—” Naz’s jaw worked like he was grinding down a thought. He looked bitter in a way that didn’t fit his usual swagger.

  “A woman’s obsession is scary, Naz-kun,” Hanara cut in, stepping over his sentence like it was a stone she couldn’t be bothered to walk around. The words were simple. The tone was not.

  Hanara’s voice carried a sharpness that made even Naz’s shoulders tense, the kind of intensity that wasn’t meant for jokes. For a heartbeat, it sounded like she wasn’t warning him about Claval so much as recalling something she had once survived herself. Her eyes flicked—briefly, instinctively—toward Roa, as if checking whether the memory was shared.

  Naz, for once, didn’t laugh it off. He shrugged with an awkward heaviness and shut his mouth. Rize listened, silent, because she didn’t trust her own voice. Something was twisting in her chest—something that wasn’t only fear, and that was the worst part.

  Claval’s fixation on Yu.

  Even thinking his name made the tightness shift, turning from grit to heat. Rize’s fingers curled at her sides, nails biting her palms through glove leather. She could not decide whether the feeling rising inside her was anger at Claval’s entitlement, fear of what Claval could do, or—Jealousy?

  The thought was ugly in its honesty. It made her feel exposed, like someone had pulled a curtain aside. She hated it. She hated the fact that it came at all, that it had the audacity to exist when danger was so close. Or is it something else? A warning?

  Because her body remembered Claval’s hand at her throat. Remembered how easily it had been done. Remembered, too, the way Yu’s warmth had once pressed against her skin—steady, human, impossible—and how that warmth had vanished, leaving only memory in its place.

  Rize drew another breath, deeper this time, and forced her shoulders to relax. Staying here would only let the sensation fester. The guild hall, with its lamps and paper and noisy life, suddenly felt too small for what she was carrying.

  She turned without another word and walked out.

  ?

  The inn’s window stuck the way it always did, swollen wood resisting her push until it finally gave with a soft scrape. Cold air rushed in, clean and sharp, and the wind immediately tangled in her hair, lifting loose strands as if trying to pull her thoughts out with them.

  Outside, the night was deep—so deep it looked like it had weight. The stars were scattered across it like distant sparks, twinkling with a softness that made them seem harmless.

  Too far away. Too unreachable.

  Rize leaned her elbows against the sill and let the chill seep into her forearms. She tried to match her breathing to the quiet. In the distance, the town’s lights flickered behind shutters. Somewhere below, a late passerby’s footsteps tapped over stone, then faded.

  She raised a hand and pressed her palm against her chest.

  The spot beneath her ribs felt normal—heartbeat, breath, bone. And yet she could still remember the warmth that had been there, as if her skin had learned its shape and refused to forget. The memory was not romantic in the way songs made it sound. It was rawer than that. Simpler. The certainty of someone real, close enough to share heat.

  Her fingertips flexed, pressing in gently, as if she could coax that warmth back out of her own flesh.

  “Yu…” Her voice came out rasped, scraped by exhaustion and by the lingering phantom of fingers at her throat. She swallowed and tried again, softer, like a prayer she didn’t quite believe she was allowed to make. “Please be safe.”

  The words were immediately swallowed by the vastness of the night. No answer. No sign that they had gone anywhere at all.

  Rize stayed there anyway, staring at the stars until they blurred, because moving away felt like admitting she was powerless.

  ?

  Miles away, in a world where the stars were drowned beneath city lights and concrete, Yu returned home and closed the door to his room.

  The sound of the latch clicking into place was small, but it carried in the quiet like a punctuation mark.

  His desk was exactly the way he had left it: textbooks and notebooks half-stacked and half-spilled, pens scattered, an open workbook spread like an accusation. Before all of this, that mess would have been ordinary. Evidence of a day that ended in fatigue. Now it looked foreign, as if it belonged to another version of him.

  He stood in the center of the room and realized his hands were shaking faintly. I have to keep my promise. The thought didn’t come with a grand image, only the memory of a voice—Kaori Mamiya’s voice—calling after him as he left the ramen shop.

  “Don’t neglect your studies,” she had said, firm enough to sting. “And come to school. This is a warning as a teacher.” It should have been annoying. It should have felt like the usual adult insistence, the kind you nodded at and ignored. Instead, it had lodged itself in him.

  Not because it was strict, but because it was also warm. Because underneath the rules, there had been a strange urgency, as if she was trying to anchor him to the mundane before something else pulled him away. As long as she was his teacher, she was trying to keep him from drifting too far.

  Yu exhaled and forced himself to move. He cleared his desk with quick, clumsy motions, stacking books, sliding papers into uneven piles. When the surface was bare, it felt too clean, like a stage waiting for something to happen.

  He sat in the chair. The cushion was worn in the shape of him. His knees bumped the underside of the desk, familiar and grounding.

  Yu spread his hands on his thighs, palms down, as if he could pin himself in place. Then he closed his eyes and pulled the Returner’s words up from memory.

  The story has been stolen; if detected on Amazon, report the violation.

  “Feel it,” the Returner had said. “This is intuition, but you should be able to do it even in your room. Grasp the flow of mana drifting in the air.”

  Yu inhaled slowly. At first, all he felt was ordinary air—cooler near the window, warmer near his desk lamp, carrying the faint smell of detergent from clean laundry and the stale trace of instant noodles from earlier. His heartbeat was loud in his ears, overlapping itself, too eager.

  Mana. The word still felt ridiculous. Like the kind of fantasy term you laughed at online. But he had seen too much to laugh anymore.

  He inhaled again, deeper, filling his lungs until his ribs tightened. He held the breath, not out of discipline, but because he didn’t know what else to do.

  With his eyes closed, the room changed. The darkness behind his eyelids became a canvas. Sound sharpened—the distant hum of a refrigerator through the wall, the faint buzz of a streetlight outside. His fingertips tingled, then went numb, then tingled again as blood flow argued with tension.

  Grasp the flow. Yu tried to imagine the air not as empty space, but as something filled—like dust in sunlight, like currents in water. He pictured invisible particles drifting, colliding, sliding past one another.

  His first attempt produced nothing but frustration. His thoughts kept snapping back to Rize, to the other world, to the feeling of a voice reaching across an impossible distance.

  He forced himself to return to the room. Inhale. Exhale. The third time, something changed.

  It was subtle—so subtle he almost missed it. A faint warmth blooming at the tips of his fingers, not the kind created by blood or friction, but something cleaner. Like a tiny ember settling under skin. Like light before it became visible.

  Yu’s breath caught. He didn’t move his hands. He didn’t even swallow. He held himself as still as possible, terrified that if he startled the sensation it would vanish.

  The warmth gathered, concentrating at the pad of his index finger. He could feel it pulsing, not with his heartbeat, but with a rhythm that seemed to belong to the air itself.

  Then—faintly—light appeared. A pale glow dwelled at the tip of his index finger, steady and delicate. It wasn’t bright enough to illuminate the room, but it was unmistakable: a living point of radiance hovering just above his skin. Yu opened his eyes.

  “There—” His voice broke. “It’s here!” He tried again, breathless. The light remained. Stable.

  Just a few seconds. But those seconds were the first time he could honestly say he had controlled it. Not imagined it. Not stumbled into coincidence. Controlled it.

  “I did it…” Yu whispered, and the words were half disbelief, half triumph. “Rize—wait for me.” A laugh almost escaped him, too sharp to be joy, too shaky to be calm. Something bright flared in his chest, a small star of determination.

  And then the room answered with a violent, ugly noise.

  Zzzzt.

  The overhead light flickered, the fluorescent tube stuttering as if the electricity itself was choking. The glow on Yu’s fingertip wavered. His smartphone, lying on the desk, began to vibrate on its own. It slid a few centimeters as it buzzed, dragging across wood with a faint scrape.

  “Eh?” Yu’s mouth went dry. The light blinked again. The hum of electricity in the room shifted into a harsh static hiss. Even the clock on the wall seemed to hesitate, its ticking skipping a beat like a heart missing a pulse.

  Yu stood so fast the chair legs screeched.

  ?

  In a quiet kitchen elsewhere, the Returner froze with a ladle in hand. The soup he had been stirring rippled once, then went still, as if the air had tightened around it. His eyes narrowed at nothing, gaze fixed on the invisible, on a pressure only he could feel.

  “Someone is trying to cross over again…” he murmured. The words were not surprised, exactly—but they were sharp with alertness. “Did that kid manage to do it already? …No.” His jaw tensed. “This pressure is different.” He listened with his whole body.

  ?

  Deep in another world, where the trees were older and the night smelled of damp earth and distant smoke, the Secret Hut sat hidden in the forest like a buried memory.

  “Here.” Claval pushed the door open and stepped inside with slow, certain grace. The hut held onto what had happened within it. Wood absorbed more than sound; it absorbed presence. The walls carried a faint stain of heat, the floorboards remembered footsteps, the air itself seemed to hold a residue that wasn’t quite scent and wasn’t quite mana.

  Claval inhaled as if tasting it. The fluctuation in the air. The temperature. The place where Yu and Rize had existed together, undeniably, for a span of time.

  It was intimate in the cruelest way: proof. Claval’s eyes slid shut. Beneath her ribs, something pulsed—faint, persistent, like a needle tapping from the inside.

  “Heh… I knew it.” She smiled, and the expression was gentle enough to be terrifying.

  Pale light gathered around her, floating in soft halos that didn’t obey gravity. Static noise crept into the edges of the glow, a whispering distortion that made the ceiling beams creak as if the hut itself was being rubbed the wrong way.

  Particles of mana danced in the air, bright flecks that made the shadows twitch. Claval lifted her hand slowly, fingers tracing the air as though following a thread.

  Yu’s lingering scent—no, his trace, his coordinate—guided her. It wasn’t the vague sense of a person being near. It was precise. A line drawn across worlds. An Address.

  “Found it,” she whispered, satisfaction curling through the words.

  Light arced from her fingertips, and the air in front of her warped. The distortion looked like heat haze at first, then sharpened into something more structured—an afterimage of a window frame hanging in space, edges flickering with interference.

  It was wrong to see inside a wooden hut: a rectangle of void, humming like a live wire.

  Proof of tampering with the EWS observation network. Proof that she could wedge her fingers into the crack between worlds and pry.

  Claval’s eyes gleamed. She stepped closer. The light clung to her hair, turning silver into something almost white.

  “Wait for me, Yu,” she said softly, as if speaking to a lover across a thin wall. “This time, I’ll meet you properly.” The glow thickened, swirling like water taking shape around her.

  Then it swallowed her whole.

  ?

  In Yu’s room, the smartphone vibrated again.

  Buzz. Buzz. Buzz.

  No notification sound. No familiar chime. Just the raw, insistent trembling of the device against the desk. Yu stared at it as if it were an animal that had suddenly moved on its own. The screen remained black—yet faint white noise swayed across it, like static trapped beneath glass.

  “Again…” Yu whispered, and his voice sounded far away to his own ears.

  The overhead light almost went out. The fluorescent bulb stuttered, flickering hard enough to turn the room into a strobe of pale snapshots. Shadows jumped along the walls. The air became thick, pressing against his skin, and a gritty noise spread deep in his ears as if someone had poured sand into his head.

  Clack. A pen on the desk stood up on its own. Clack-clack. It rattled, tapping like teeth chattering. Yu’s skin prickled as if static electricity were biting him, sharp little stings along his arms. It felt, absurdly, as if the world itself were creaking under pressure.

  Then the smartphone screen turned on by itself. The EWS app UI appeared—only it wasn’t the usual stream interface. No viewer count. No comments. No chat. The familiar layout had been stripped away, leaving something stark and wrong. It resembled the abnormal “Mutual Communication” screen—the one that had appeared when he had connected with Rize beyond a simple broadcast.

  Yu’s stomach dropped.

  “This is…” he began, then stopped, because his tongue felt thick. A voice reached his ears. Not from the phone speaker as sound alone, but as presence—close enough to raise the hairs on his neck.

  Yu… can you hear me?

  His breath caught in his throat so hard it hurt. No image floated on the screen yet. Only the voice, clear and intimate, as if speaking directly into his room.

  “Claval…?” Yu swallowed. The moment he said her name, light seeped out from the edge of the smartphone.

  White radiance overflowed beyond the LCD, spilling across the desk and dripping onto the floor as if light could become liquid. The floorboards brightened in a widening pool. The walls caught it next, pale and trembling.

  The entire room distorted, rippling as though the air had turned to water. Posters and curtains swayed without wind. The shadow under his bed stretched, then snapped back.

  No… this isn’t just a stream. Cold sweat ran down Yu’s spine. The space between his bed and the window expanded, impossible geometry unfolding like a slow yawn. Light gathered there, thickening, shaping itself into an outline.

  A blurred silhouette took form. Hair. Clothes. The rise and fall of breathing. Yu couldn’t move. His muscles refused.

  A footstep landed on the floor with definite weight. Step. The sound echoed, too loud in the silence of Japan. Standing there was no longer an illusion through a screen.

  Claval—real, present, impossibly here—smiled quietly.

  “Eh…?” Yu’s throat produced a broken sound. Claval shook her platinum-silver hair, then tilted her head as if amused by his disbelief. Her eyes shone like jewels, bright and merciless, piercing straight through him.

  “Nice to meet you, Yu.” She took a step forward. Her toes sounded on the flooring again, and the noise was unnaturally sharp, like the room had become an empty hall built to carry her presence.

  Yu backed away without realizing it until his shoulders hit the door. The cold wood at his back did nothing to steady him. His heart rampaged in his chest. His limbs felt heavy as lead.

  “I came for you.” Claval’s smile deepened, sweet as honey and twice as dangerous. The words shook the air. And with them, the room’s smell changed.

  It wasn’t the familiar oily warmth of a ramen shop, nor the dry paper-and-ink scent of school. It was something foreign and unmistakable: crushed greenery, iron like blood, and dense mana that seemed to thicken the air until breathing felt like drinking.

  Yu forgot to inhale. He could only stand there, trapped between the door and the impossible. In the night’s silence, only Claval’s smile floated vividly—proof that this was no longer observation through a screen, no longer a broadcast he could shut off with a tap. The invasion had begun.
