The residential streets were sinking, drowning in the heavy, bruised colors of a dying sun. To the west, the sky was a bleeding wound of violet and burnt orange, casting long, distorted shadows that stretched across the asphalt like grasping fingers. It was the time of day when the boundary between the mundane and the magical felt thinnest—the Twilight Hour.

  Cars passed in rhythmic waves, their headlights cutting through the encroaching gloom with blinding white beams. The tires hummed against the pavement, a monotone drone that vibrated in the soles of Yu’s shoes. somewhere in the distance, the high-pitched laughter of children playing in a park echoed, fading as they were called home for dinner by unseen parents.

  It was a scene of perfect, suffocating normalcy. And in the middle of that everyday scenery, Yu walked. His footsteps felt heavy, hollow, as if his body were made of lead. He moved through the crowd of commuters and students as though he alone had been cut away from the world with a pair of scissors—a cardboard cutout placed on a moving background that he no longer belonged to. The air around him felt different, thinner, charged with the static of a world that was miles and dimensions away.

  He reached his house. The nameplate on the gate looked the same as always, but it felt like reading a stranger's name. He inserted his key. The metal scraped against the tumblers—scratch, click, thud—a sound that felt deafening in his ears.

  When he pushed open the front door, the warm, yellow humidity of the hallway washed over him. The lights were already on, casting a welcoming glow on the shoe rack. The rich, savory smell of dashi stock and grilling fish drifted from the kitchen, wrapping around him like a suffocating blanket of nostalgia.

  “Welcome home, Yu.” His mother’s voice floated from the living room. It was gentle, routine, the sound of safety.

  “I’m back.” The words tasted like ash in his mouth. He slipped off his sneakers, aligning them neatly out of habit, though his mind was already calculating departure vectors.

  He walked into the living room. His mother stood by kitchen, her back to him. The ventilation fan hummed softly. She was stirring a pot, the metal ladle clinking rhythmically against the enamel. But as he entered, the rhythm faltered. She paused. Her shoulders stiffened, the fabric of her apron pulling tight.

  She didn't turn around immediately. She stared into the bubbling soup as if trying to divine the future in the broth. Then, she turned. She didn't smile. Her face was pale, the lines around her eyes tighter than usual. She gripped the ladle as if it were a weapon or a lifeline.

  “Yu… can we talk for a moment?” She asked. It was the hesitation of someone holding back a confession that could shatter their world.

  “?? What happend?” Yu pulled out his usual chair at the dining table. The scrape of wood against the floorboards sounded like a scream. He sat down, placing his hands on his knees.

  His mother approached slowly, wiping her hands on her apron over and over again, a nervous tic he hadn't seen in years. She sat opposite him. The table between them felt like a canyon.

  “I was watching TV the other day.” She started without preamble, her voice steady but brittle. “There was this… feature about those streaming apps everyone talks about lately. The ones young people use to watch games and… other things.”

  “Mom…” Yu started, a warning in his tone, but she pressed on.

  “And then I saw a clip from that…app, so Echoes Watching System. The news was making a fuss about it.” Her voice trembled, cracking on the last syllable. She looked up, her eyes locking onto his, searching for a lie she hoped she wouldn't find. “…Yu, you were in it, weren’t you?”

  The words hit him like a physical blade—quiet, precise, unavoidable. It severed the last thread of his disguise. The living room felt too bright. The fluorescent lights buzzed like angry insects. The silence stretched, filled only by the ticking of the wall clock. Tick. Tock. Tick. Tock.

  Yu lowered his gaze. He stared at the grain of the wooden table. He could lie. He could say it was a look-alike, a deepfake, a prank. He could laugh it off and ask about dinner. But not to my mother. He clenched his fists, his fingernails digging into his palms until it hurt.

  “And that girl… Claval-chan.” His mother leaned forward, her voice dropping to a conspiratorial whisper. “I thought she was just a very, very committed cosplayer. A friend of yours from school who liked costumes.”

  “But… she isn’t, is she?” She took a shaky breath, her eyes watering. “She’s the real Claval, isn’t she? The adventurer from the other world?”

  A sensation of cold and heat rushed through Yu’s chest at the same time. She knew. She had pieced everything together on her own.

  “Yu… please tell me.” Her hand reached out, hovering over his. “You’re not doing anything dangerous, right? No one’s forcing you? You’re not helping criminals?”

  Her voice wasn’t accusatory. There was no anger, only pure, distilled terror. It was a mother begging to believe that her son was still hers, that he hadn't been stolen by a world she couldn't understand.

  Yu looked up. He forced his facial muscles to relax.

  “I’m okay. I swear—I haven’t done anything wrong.” He nodded slowly.

  She exhaled. It was a long, shuddering sound, like a balloon losing all its air. Her whole body sagged as the tension left her. She smiled—a wobbly, fragile smile on the verge of tears.

  “Good. That’s good.” She wiped her eyes. “Then I’m on your side, always. Whatever happens. Whoever you are.”

  Something in Yu’s chest unraveled. The knot of isolation that had tightened around his heart since returning began to loosen.

  “…Thanks, Mom.” Yu said. And at the same time, something else rose—a pillar of strength.

  She smiled again—soft, trembling, but undeniably strong.

  ?

  “I think… I can do it from here too.” Yu stood up. The movement was sudden, decisive. A decision had crystallized inside him. It wasn't a choice anymore; it was a necessity. The support of his mother was the final key he needed.

  “Do what…?” his mother asked, blinkered confusion replacing her relief.

  Yu walked to the center of the living room, near the large windows that looked out onto the darkening street. He stood with his back to the television, facing the empty air. He extended his right hand.

  Vooooom.

  The atmosphere in the room changed instantly. Pressure dropped. The air grew heavy, thick, charged. Static electricity raised the fine hairs on his mother's arms. The dust motes in the air stopped moving, suspended in a localized stasis.

  A pale blue glow gathered at Yu’s fingertips. It wasn't just light; it was concentrated meaning. Space warped—not tearing like paper, but untying like a complex knot being undone by invisible fingers. A distortion opened in the middle of the suburban living room.

  ROAR.

  Wind roared through the house, violent and sudden, pulling the lace curtains toward the rift as if into a vacuum. Papers flew off the dining table, scattering like birds. The hanging light fixture swayed wildly, casting dancing, nauseating shadows across the walls.

  “Yu!?” His mother instinctively stepped back, shielding her face with her arm. This wasn’t air-conditioning wind. This wasn’t a draft. The world itself was reacting to Yu. Reality was bending around him, groaning under the weight of his will.

  A shining ring—liquid, wavering, rippling like mercury—hung open in midair. It was a window into the void, a tunnel through the fabric of existence.

  “Mom,” Yu said gently. He didn't look back at the destruction in the living room. His eyes were fixed on the darkness beyond his hand. “I’m going out for a bit. I need to visit Claval.”

  You could be reading stolen content. Head to the original site for the genuine story.

  “Yu… what is that…?” His mother’s voice quivered, terrified by the impossible magic unfolding next to her sofa.

  “When everything’s over… there are two people I want you to meet.” He turned his head. He offered a small smile. It wasn't the smile of a worried teenager carrying the weight of the world. It was the same innocent, excited smile he’d had as a child before a school trip.

  “Two…?” She tilted her head.

  “See you soon.” Yu called.

  The light flared. It became blindingly bright, a supernova in a box, swallowing his silhouette completely.

  “Yu—!!” Her cry came too late.

  The glow collapsed inward with a sharp snap, like a thunderclap in a jar. The wind vanished. The pressure returned to normal. Only the swaying curtains remained, drifting slowly back to rest. One heartbeat later, she gasped, clutching her chest as her heart hammered against her ribs.

  “What in the world…?! H-he scared me half to death!” She fumbled for her phone on the table, her fingers shaking so hard she could barely unlock the screen. She nearly dropped it twice. “I need to call your father! He won't believe this! I have to…”

  But deep down, as she dialed the number, she already understood. Her son no longer fit inside the “normal world.” He had outgrown the safety she could provide. He belonged to the storm now.

  ?

  Light reversed. Gravity inverted. Yu felt weightless, suspended in the kaleidoscope of the void. His stomach lurched, his equilibrium shattering and reassembling in a microsecond. Then, the universe snapped back into place.

  Crack.

  The smell of miso soup and fabric softener vanished. Replaced by the scent of crushed grass, damp earth, and the metallic tang of raw mana. A familiar sky stretched overhead, vast and filled with foreign constellations that no astronomer on Earth had ever named.

  “…I’m back.” He stood once more on the plains of Avras, where the black dome had once stood. Everything here was real in a way that made his chest tighten. The wind bit at his exposed skin. The ground was uneven under his soles. The air tasted richer, deeper.

  Mom, Mamiya-sensei, the comments online… they’re all supporting me. The thought wasn't a comfort; it was fuel. It was a foundation. Support… feels good. It gives me strength. It justifies me.

  His eyes glimmered faintly blue, reflecting the mana in the air. He wasn't just a visitor anymore. He was a participant.

  “Wait for me, Claval. I’m coming.” Yu whispered. The grass behind him shuddered as if stirred by his presence, bowing to the new king of this domain.

  ?

  Yu walked down the slope at the edge of Avras, his steps purposeful. The small wooden clinic sat quietly among the trees, smelling of drying herbs, old timber, and the faint, sweet scent of recovery.

  He steadied his breath. He pushed open the door. Warm, orange lantern light filled the room, banishing the twilight gloom. Rize sat beside Claval’s bed, adjusting blankets and sorting herbs on a wooden tray. Claval was propped up on pillows, looking pale, her silver hair loose, but her eyes were alert.

  “Sorry I’m late.” Yu greeted.

  When they both turned to him, something bright sparked inside Yu’s chest. A feeling of rightness.

  “Don’t worry. Rize kept me entertained. She’s a terrible nurse, though. She keeps trying to feed me combat rations.” Claval smiled weakly, lifting a hand to wave.

  “Her mouth works fine, but she still needs rest. She’s stubborn.” Rize crossed her arms, huffing indignantly.

  “And this girl? Just a minute ago she was screaming, ‘Yu’s getting closer! He’s coming! I can feel him! Rize, do my makeup! Don't let him see me like this! My hair is a mess!’” A mischievous glint entered Rize's eyes. She smirked, leaning back in her chair.

  “…You weren’t wearing makeup when you got out of the bath during this time. You looked fine.” Yu winced.

  Rize froze. The room went dead silent.

  “…Bath?” Rize’s voice dropped an octave.

  Yu slapped a hand over his mouth. The blood drained from his face. Too late.

  “W-wait—you didn’t have to say that! Not in front of Rize! That’s a secret!” Claval’s face went crimson, matching the carpet. She buried her face in her hands, peering through her fingers.

  “I—I didn’t mean anything weird! It was an accident!” Yu also answered hastily too.

  “…Oh? I see. I see how it is. Bathing together, huh? While I was training for my life?” Rize stared at him with narrowed eyes, her aura turning visibly dark.

  Yu looked away, whistling innocently, sweating bullets. The tension eased—briefly. Laughter bubbled up, a fleeting moment of peace in a world.

  “Someday,” Yu said softly, breaking the laughter, looking at both of them with a newfound seriousness. “I’ll bring Rize too. I want her to meet my mom. Claval too.”

  “Yu… does that mean—” Rize blinked, stunned. Her anger vanished.

  ?

  BOOOOOOM.

  The atmosphere shattered. The peace was annihilated in an instant. The windows rattled in their frames, threatening to burst. A shadow streaked past outside, blocking the sun, casting the room into sudden darkness. Bottles crashed to the floor, glass shattering and spilling pungent tinctures everywhere.

  “What—!?” Rize sprang to her feet, running to the window. “No…”

  A mass of black crawled across the ground, churning like a living storm, devouring the light.

  “That thing again! The monster that destroyed my town!” Rize’s face paled.

  It was huge—a titan of smoke and malice. Its skin looked like shifting metal plates, smoke pouring from its jaws, eyes glowing with red, hateful light. It was a nightmare made flesh, a remnant of the catastrophe.

  “I’ll handle this—I can still magic—” Claval pushed herself upright, wincing in pain as her wounds protested.

  “No you won’t!” Rize snapped, pushing her back down onto the mattress. “You can’t even stand! You’ll tear your stitches!”

  Then Yu stood. He walked past Rize. He walked to the window. He looked out at the monster that terrified veterans. He raised his right hand.

  “Both of you. It’s okay. I’ve got this.” His voice was calm. Unnaturally calm.

  Blue light wrapped around him like a second skin. It wasn't the soft, organic glow of healing; it was the hard, geometric light of structure. I get it now. I finally understand what [Bind] is.

  Echoes reverberated in his mind, a chorus of lessons layering over each other, synchronizing into a single truth—

  Returnee: “Magic is imagination. Don't be bound by form.”

  Mamiya: “Mana is used as a medium to convert information and then convert it into electronic signals. Therefore, what we see is merely [translated mana.]”

  Roa: “…Are you even human?”

  Hanara: “I've created so many spells that it's become a pain to have to cast and construct them one by one.”

  Naz: “[Maximize] — Full Spec!”

  Returnee: “Use it well, Kid.”

  ?

  “[Bind.]” Yu clenched his fist. The air screamed as if in pain.

  SNAP.

  The air ripped open. It wasn't a beam. It wasn't an explosion. It was a deletion. Blue light swept outward in a horizontal wave, ignoring distance, ignoring resistance, ignoring the laws of physics.

  The monster outside—a creature that had devastated cities, a beast that required armies to suppress—fell into perfectly sliced segments. One moment it was a roaring behemoth. The next, it was a stack of disconnected blocks.

  It collapsed like a structure with all supports removed. Thud-thud-thud. The impact shook the ground. Shattered flesh scattered into the wind, dissolving into dust before it even hit the ground. It didn't die; it ceased to exist. Silence. Absolute, terrifying silence.

  Rize and Claval stared, stunned. Their mouths hung open. Even the soldiers rushing outside froze mid-step, their weapons lowered, unable to comprehend the violence of the miracle they had just witnessed.

  “This is the true [Bind.] From now on—I’ll protect you both.” Yu lowered his arm. Wisps of blue smoke drifted from his fingertips.

  Skreeeee.

  The air warped outside again, twisting like a wet rag.

  “Well, well—looking very final-boss-ish today, Yu Shiro! Talk about a power trip!” A rift cracked open where the monster had stood. From within came a mocking, familiar laugh. Stepping out of the black mist, a man appeared. A long coat fluttering in the wind. A familiar, arrogant smirk.

  Time Patrol. A man who should have vanished with the Returnee. A ghost.

  “TP...! They were supposed to have disappeared along with Hoshimine-san...!” Yu’s breath caught in his throat.

  “I said ‘see you again,’ didn’t I? Or do you prefer the ‘I’ll be back’ version?” TP shrugged, dusting off his coat as if he had just stepped off a bus.

  “You bastard—!” Yu’s fist trembled. Rage boiled over, white-hot and blinding.

  Then— A voice brushed his ear. Soft. Sweet. Unbearably, intimately close. It wasn't Rize. It wasn't Claval. It was a whisper from the void, a voice that bypassed his ears and spoke directly to his brain stem.

  “Aaah, don’t worry… He can’t move anymore.”

  “Who…?” Yu spun around, scanning the empty room. No one was there. Yet the voice was unmistakably close, damp, as if lips were touching his earlobe.

  “I [bind] the whole area’s mana around hiiiiiimm”

  Yu moved. He didn't think he reacted. Guided by invisible strings, his hands came together. Light formed between his palms. A cube of pure, condensed blue energy. A cage of logic.

  “W-wait—this trait—This is the Returnee’s!! Yu Shiro! Stop it!! Is that zone—” TP’s face twisted in genuine horror. His smirk vanished.

  SNAP.

  A sharp, dry sound echoed. Like a twig breaking in a winter forest. Light burst. TP vanished. Not teleported. Not killed. Erased. The space where he stood was empty, scrubbed clean.

  Yu lowered his hands. He exhaled softly. Behind him, Rize and Claval stood frozen. Unable to speak. Barely able to breathe. They were looking at a god, or perhaps a monster.

  “Yu…” Rize whispered, fear mixing with awe.

  He turned to them. He smiled. It was a gentle, terrifying smile, the smile of someone who has looked into the abyss and found it comfortable.

  “It’s okay. As long as I’m here—this world won’t fall.” His eyes glowed with the same deep, endless blue as pure mana, cold and beautiful and utterly inhuman.
