Yu let out a long, tired sigh the moment he stepped into the entryway.

  The hallway smelled like detergent and miso soup that had cooled down hours ago. His school bag slid off his shoulder with a dull thump, and the quiet of the house wrapped around him—soft, domestic, safe in a way that now made his skin itch. His body still remembered mana like a phantom pressure. Even when he wasn’t using it, his nerves felt tuned too tightly, like a guitar string one touch away from snapping.

  Please. Just let today be normal. The thought didn’t even finish forming before that familiar, crawling unease rose in his chest. Yu slipped off his shoes, climbed the stairs, and reached for his bedroom door. The knob turned. The door opened. And there she was.

  “Welcome home, Yu.” Claval sat by the window with her chin propped on her hand, silver hair catching the sunset like it had been poured over her head. The orange light made her look unreal—too clean, too bright—like an illustration pasted into an ordinary room.

  “…You came in again without asking.” Yu froze in the doorway. His heartbeat stumbled once, then started again, harder. He forced the words out, but the complaint landed weakly in his own ears. The room already smelled faintly of potato chips.

  “Oh, don’t worry about that?” Claval smiled as if she’d been invited. She didn’t even move from the window, only tilted her head a fraction, watching him like this was the most natural scene in the world.

  Yu’s gaze dropped. A convenience-store bag sat on his bed. The plastic was crumpled, the handles stretched. Chips, chocolates, and candy wrappers peeked out like evidence.

  “Your mother gave me snacks, by the way.” Claval’s voice was bright, almost proud. “So kind. I accepted properly.”

  “…How are you this comfortable here already?” Yu pressed his palm to his forehead. His temples throbbed—not quite pain, but a warning. His room used to be a place where the worst threat was unfinished homework.

  “Because I want to learn more about your world.” Claval popped another potato chip into her mouth with casual elegance, chewing slowly like she was tasting the concept of salt itself.

  Yu’s eyes tracked past her to his desk. His tablet was open. The screen glowed with a simple page layout, and the built-in voice read with tireless neutrality.

  —The Kamakura shogunate began in 1185—

  The synthetic voice didn’t pause for disbelief. It kept going, steady as rainfall.

  “…You can’t even read the language.” Yu blinked.

  “I can’t.” Claval didn’t look embarrassed. She looked delighted. “But after touching things, the tablet started reading them to me. Convenient magic.” She reached out and swiped the screen as if she’d been doing it for years. The tablet obeyed instantly, and Yu felt a small, sick twist in his gut. She’s adapting too fast.

  “This world, your country, its history and culture…” Claval’s eyes shone with a genuine hunger. “Everything is fascinating.”

  The tablet continued in the background, its voice now shifted to something more clinical.

  —DNA stands for deoxyribonucleic acid. It carries genetic instructions for development, functioning, growth, and reproduction—

  “Hold on.” Yu’s spine went cold. He stepped into the room fully, letting the door close behind him with a soft click that sounded too final. “What are you researching now?”

  “The structure of the human body.” Claval said it like she was discussing a new dungeon route. “DNA, ES cells… the biology of this world is incredible.” Her curiosity wasn’t playful now. It was sharp, bright, almost feverish. There was no room for jokes in her tone.

  “…Seriously,” Yu said, and his voice came out smaller than he wanted. “What are you planning?” He swallowed. His throat felt dry, and for a second he remembered the way mana had thickened the air in his room—how the world had felt subtly wrong even before the pain hit.

  “Yu, our relationship…” Claval paused with deliberate sweetness. “In your world’s history, it’s called Shudō, right?” Her smile didn’t vanish. It simply deepened, like she’d been waiting for him to ask.

  “B—WHAT!?” Yu’s voice cracked. Heat rushed to his face so fast his ears rang. “Where did you even find that word!?”

  “It said so in the history database.” Claval’s tone was soft and sincere, which only made it worse. Claval blinked slowly, genuinely innocent, as if she’d asked about the weather. “The way of the samurai. A beautiful bond between two men who share their hearts and bodies.”

  “Don’t say that with such a straight face!!” Yu grabbed his head with both hands. The embarrassment hit him like a physical force, and somewhere beneath it, fear coiled tighter.

  Claval’s gaze didn’t waver. No teasing glint. No smug victory. She wasn’t joking. With a small, satisfied motion, she tapped the tablet and closed it. The voice cut off mid-sentence, leaving a sudden silence that made Yu’s skin prickle.

  “…And if I combine this biological theory with magic,” Claval murmured, “my wish might be possible.” Her voice carried a strange heat. Not loud. Not urgent. Just certain, like a blade sliding out of a sheath.

  Yu’s chest tightened. He didn’t know what she meant in detail, but he knew enough to feel the weight of it.

  “Hey—”Yu started, but his words caught.

  “Let’s go out.” Claval stood, brushing crumbs from her skirt with delicate fingers. The motion was so composed it felt insulting.

  “…Out?” Yu stared at her. “Aren’t you supposed to go back to your world?”

  “Either is fine.” Claval stepped closer, and the sunset light flashed along her silver hair like a warning. “As long as I’m with you.”

  She smiled—innocent, bright—and Yu felt that same cold ripple slip down his spine.

  ?

  Busy downtown area hit them like a wave. Noise, light, smell—everything stacked on top of everything else. Traffic hummed and coughed. Crossing signals chirped in quick rhythms. People flowed in thick streams, shoes striking pavement in overlapping patterns that made the ground feel alive beneath Claval’s feet.

  “Wow… the buildings here look tall enough to reach the sky.” Claval craned her neck, staring up at towers of glass and steel. The sunset reflected in windows like a thousand small suns. “Towers of glass.” Her eyes sparkled the moment she saw the skyline.

  “Don’t get too excited,” Yu muttered. “People are staring.” He tightened his grip on the strap of his bag, suddenly hyper-aware of every passing gaze. They were.

  Claval didn’t just stand out—she broke the rules of the scenery. Her silver hair, her perfect features, the way she moved with effortless poise… strangers glanced once and then looked again, whispering, hesitating like they were trying to place which model campaign she belonged to.

  “Cosplayer?” someone murmured behind them.

  “Is that a shoot?” another voice asked.

  Yu’s cheeks warmed. He kept his eyes forward and tried to walk like he wasn’t escorting a fantasy adventurer through one of the busiest districts in Japan. Claval, of course, didn’t care. She moved through the crowd like a queen strolling through her own palace, curiosity lighting her face.

  “Let’s go in here.” Claval pointed at a trendy fashion mall, its entrance glowing with clean white light and polished displays.

  “Clothes?” Yu blinked. “Seriously?”

  “I want to experience the clothing of this world.” Claval’s tone was matter-of-fact, as if this was a vital research mission. Then she added, with a small smile, “And you want to see it too, right?”

  Yu opened his mouth to deny it. Claval hooked her fingers around his sleeve and pulled. Before he could protest, he was dragged inside.

  The air changed instantly. Warm and conditioned. Perfume layered over fabric smell. The lighting was bright enough to erase shadows, and the mirrors multiplied them into a maze of reflections. Claval walked among racks like she’d entered a treasure vault.

  “This fabric…” Claval rubbed a sleeve between thumb and forefinger, eyes narrowed in appreciation. “It feels like woven magic. So light.”

  “It’s just polyester fiber,” Yu said, already sounding tired.

  Claval’s attention drifted from one piece to another, fingertips brushing hangers, tags, seams. When she lifted a white dress from a rack, the thin fabric caught the light and looked almost luminous in her hands.

  “I’ll try this.” Claval turned to him, eyes bright with expectation. Yu’s stomach dropped.

  “Yu, make sure you watch.” She stepped into the fitting room with a pile of clothes balanced against her chest and pulled the curtain shut with a crisp swish.

  “Wha—! I’m not watching!!” Yu spun on his heel so fast he almost collided with a passing shopper. His face burned. He stared hard at a wall display of scarves, as if the patterns were suddenly the most fascinating thing in existence. Behind him, the soft rustle of fabric made his heart jump anyway. He hated that. He hated how easily his body betrayed him—how it responded before his brain could wrap itself in logic and excuses. Then the curtain slid open.

  “I’m ready.” Claval’s voice. Yu turned despite himself. Claval stepped out in the simple white dress, the fabric falling cleanly along her figure. She brushed her silver hair aside with an absent gesture, like she was clearing a curtain from a window so the world could see properly.

  For a second, the store noise muted. The bright lights seemed to cling to her. She looked absurdly beautiful—like a goddess who had wandered into a shopping mall out of boredom.

  “How do I look?” Claval asked, voice calm, eyes fixed on him.

  “It looks good.” Yu’s throat tightened. “…Really, Really good.” The words came out honest before he could stop them.

  “I knew it.” Claval’s smile softened. Something in her gaze warmed. “Being praised by you makes me happy.” And that warmth landed in Yu’s chest like a stone dropped into water. She turned toward a mirror, striking a pose like she belonged on a billboard, turning slightly so the dress caught the light.

  “Please… stop drawing attention…” Yu muttered. He flinched at the attention it drew. Claval didn’t seem bothered. If anything, she looked pleased—as if being noticed here, in his world, meant she was anchoring herself deeper into it. And deeper into him.

  ?

  “Seriously,” Yu muttered, as they left the mall, “calm down. You’re way too noticeable.” His words were half complaint, half prayer.

  Claval walked beside him with the new clothes bag swinging lightly at her side, like the weight meant nothing. Her expression was bright—pure enjoyment—like she was tasting the city itself.

  Yu stopped at a stall and handed her a skewer of mitarashi dango, hoping food would slow her down. Claval bit into it.

  “Mmm—sweet and salty!?” Her eyes widened in delighted shock. “This world’s sweets are amazing!”

  The reaction earned even more stares. A group of teenagers slowed, whispering. A man in a suit glanced twice. Yu’s shoulders hunched instinctively, as if he could hide behind his own posture.

  “It’s just… normal,” he muttered, but his voice didn’t reach her.

  Claval was already drawn to the next thing: a crepe stand, the air around it thick with the smell of cream and strawberries. She ordered with confident gestures and a smile that made the cashier flustered. When she took her first bite, her expression turned almost reverent.

  “This thin sheet holds so much…” She turned the crepe like it was a magical artifact. “Better than magic!”

  “It’s just cooking technique,” Yu said again, automatically, but she didn’t hear him. She was too busy enjoying the taste, licking a smear of cream from her lip without any awareness of how that tiny motion made Yu’s heart slam against his ribs.

  They walked through the crowd, and the distance between them shrank without either of them acknowledging it. Shoulders brushed. A sleeve grazed his wrist. Every accidental contact felt louder than the city noise. Yu tried to tell himself it didn’t mean anything. That it was just crowded. That this was normal. But his body didn’t believe him. Then Claval stopped so suddenly Yu nearly bumped into her back.

  “Yu.” The way she said his name made the world tilt a fraction.

  Yu turned, confused, and saw her looking over the crowd—eyes scanning faces, movements, patterns. Not like a tourist now. Like a hunter measuring terrain. Then she smiled.

  “With this many people,” Claval said softly, “we won’t stand out at all, right?”

  “…What are you trying to say?” Yu’s stomach tightened. The sweetness in her voice didn’t reach her eyes.

  “Hiding within a herd isn’t bad.” Claval’s gaze sharpened.“Especially when I’m with you.” Piercing the flow of strangers like she could see the bones beneath the skin. The words should’ve been harmless. Almost romantic, even.

  Instead, they carried a chill that slid under Yu’s ribs and stayed there. The noise of the world faded at the edges. For a heartbeat, it felt like the crowd wasn’t protection—it was camouflage. Like being surrounded didn’t mean safety. It meant cover. Claval reached out and took his hand. Yu stiffened. Her fingers were warm. Her grip was gentle. But it was also certain.

  “Yu,” Claval asked, smiling sweetly, “where do we go next?”

  “…Just—” he tried, but the sentence died. Yu stared at their joined hands, then up at her face. Her expression was soft, inviting—yet something in it burned with a heat he couldn’t interpret. His throat felt dry again. He forced a breath in.

  Claval squeezed his hand once, as if encouraging him. And Yu, against his better judgment, didn’t pull away.

  ?

  Night settled over the streets, and the city changed its skin.

  The harsh brightness softened into warm lamps and neon glow. Tree-lined sidewalks shimmered faintly with cold. Yu’s breath turned white in the air, and every exhale felt like it carried tension out of him, only for the next inhale to drag it back in.

  They walked side by side, the shopping bag rustling softly, their footsteps in uneven rhythm. Claval slowed. Then she stopped. Yu took one more step before realizing, and turned back toward her. Streetlight painted her silver hair in pale gold. The glow caught at the edges of her face, making her eyes look deeper, darker.

  “Yu.” Her voice was low now. No teasing. No playful lilt. Just a quiet seriousness that made Yu’s spine straighten. Claval stepped closer, and the space between them felt suddenly loud—filled with the things they hadn’t said, the lines they’d crossed without naming. “With you,” she said, and the words landed carefully, like she’d chosen each one, “I can make a future.”

  Yu’s heartbeat surged into his ears. The city noise blurred into a distant hum, like he’d stepped behind glass.

  Claval’s gaze pierced him—desire in it, yes, but also something sharper, something dangerously close to obsession. Like she wasn’t just imagining a future. Like she was claiming it. Yu swallowed hard. His mouth opened. No words came. Anything he said felt like it would be swallowed whole by the gravity in her eyes.

  “Claval…” Yu managed, weakly, and hated himself for how small it sounded. Claval closed the last inch of distance.

  “Yu… please.” Her voice softened, but the intent behind it didn’t. “Don’t run.”

  His breath caught. His brain scrabbled for reasons—logical ones, moral ones, the kind adults would approve of. But his thoughts were slow, thick, tangled.

  And underneath them, something simpler moved: the warmth of her hand earlier, the way she looked at him like he was the only thing in the world worth choosing, the way loneliness had been gnawing at him for days and her presence filled it with heat.

  Their faces drew closer, tentative and uneasy, like two magnets pulled together even as they tried to resist. Yu’s hands hovered uselessly at his sides. He didn’t know whether to push her away or hold her. Claval didn’t hesitate.

  Their lips met—soft, brief, trembling. Yu felt sweetness bloom in his chest at the same time fear sharpened its teeth. The sensation braided together, impossible to separate. The cold night wind brushed past them, indifferent, while the streetlight watched like an eye that never blinked.

  When they parted, neither of them spoke. They stood there, breath white, bodies still, as if a single word might shatter whatever fragile balance had just been born between them. Claval’s hand found his again. And Yu, trembling, let it.
