Ren Ishida had perfected the art of disappearing in plain sight.
He sat in the back corner of Class 3-A, shoulder pressed against the cool windowpane, where the afternoon light barely reached him. Earbuds rested in his ears, but no music played—just a shield against the noise of thirty-two seniors buzzing about exams, club rivalries, and weekend plans. Conversations swirled around him like distant static.
No one bothered him anymore. He had become part of the furniture: quiet, unremarkable, forgettable. Teachers called his name during roll call, he answered with a soft "here," and that was enough.
Except for Yui Takahashi.
She was the single crack in his carefully built solitude.
The final bell rang, sharp and liberating. Lockers slammed in the hallway like distant thunder. Ren took his time packing his bag, folding each notebook with deliberate care, waiting for the crowd to thin. He almost made it out unnoticed when her voice cut through the fading chatter.
"Ren! Hey, wait up, you mysterious loner!"
Yui jogged toward him, her ponytail swaying with each step, skirt fluttering just enough to draw a few lingering glances from other students. A fresh band-aid decorated her left knee from yesterday's volleyball practice. Her smile was bright and persistent, the kind that refused to take no for an answer. She had decided months ago that Ren's silence was a puzzle she wanted to solve, and she attacked it with the same cheerful stubbornness she brought to everything.
"You're seriously walking home alone again?" she asked, falling into step beside him as they left the classroom. "That's just sad. Come on, walk with me. I need someone to vent to about that brutal math test, and you're literally the only person who won't interrupt me with stupid excuses or fake sympathy."
Ren glanced at her briefly, then back at the floor. A tiny twitch at the corner of his mouth almost became a smile. Almost. "Fine," he muttered, voice low and even. "But only because you'll follow me anyway."
Yui laughed, a light, genuine sound that echoed down the emptying corridor. "See? That's why I like you. You get it."
They pushed through the school gates together. The October air in Tokyo carried a faint chill, the late afternoon sun painting the streets in warm gold and long shadows. A few cherry trees still clung stubbornly to their last pink petals, scattering them across the sidewalks like forgotten confetti. Yui chattered nonstop as they walked—complaining about their homeroom teacher's impossible curve on the latest test, gossiping lightly about the volleyball team's upcoming match, teasing Ren about how he always sat "like a ghost in the corner."
"You know," she said, nudging his arm playfully, "you'd actually be pretty popular if you smiled more. Or talked. Or, you know, existed visibly. Handsome face like yours is wasted on permanent brooding mode."
Ren kept his eyes on the pavement. "Not interested."
"Exactly! That's the problem." She grinned wider. "But I'm not giving up on you yet, Ishida Ren."
At the crosswalk near the station, the pedestrian light turned red. They stopped side by side. A large delivery truck rumbled past, belching thick exhaust into the air. Yui turned toward him fully, still smiling.
"You know, one of these days I'm going to drag you to karaoke or something. Force you to sing and—"
Their eyes met.
Direct. Clear. Unavoidable.
For two ordinary seconds, nothing else existed except her warm brown eyes locked on his.
And then the world tore apart.
The vision crashed into Ren's mind like a freight train.
Night. Pouring rain hammered the alley behind the old konbini, three blocks from Yui's apartment. A flickering streetlight buzzed overhead, casting erratic shadows across wet concrete. Yui was running—sprinting desperately, breath coming in ragged, terrified gasps. Her shoes slapped against puddles. Footsteps pounded behind her.
She glanced back.
The hooded figure caught up in one stride. The knife flashed first into her stomach.
A sickening, wet thunk—metal punching deep into flesh. Yui's eyes flew wide in shock and agony. Blood erupted instantly, soaking through her white uniform blouse in a spreading crimson bloom. She gasped, the sound wet and choking, as the attacker twisted the blade viciously. Another stab drove between her ribs, piercing her lung. Ren heard the horrifying hiss of air escaping, mixed with the gurgle of blood rising in her throat.
She tried to scream. It came out as a broken, bubbling whimper.
The third strike went higher, under her collarbone, slicing through muscle and artery. Hot blood sprayed in a wide arc, splattering the alley wall like grotesque modern art. Yui crumpled backward, her back slamming against the cold, wet ground. Rain mingled with blood, turning the puddle beneath her from pink to deep, viscous red, then almost black under the flickering light.
Her fingers twitched spasmodically. Her mouth opened and closed, desperate for air that wouldn't come. The last image burned itself into Ren's soul: the hooded figure leaning over her… pulling the hood back just enough.
It was his own face staring down at her—twisted in horror, hands already covered in her blood, screaming her name as her eyes slowly lost focus and went glassy.
The metallic stench of blood flooded his nostrils. The cold rain on her skin. The final, rattling exhale as life left her body.
Then, nothing but darkness.
Reality snapped back in an instant.
Ren staggered backward on the crosswalk, nearly losing his balance. Horns blared from impatient drivers. The light was still red. His heart slammed against his ribs so violently he could taste copper in his mouth. The vision replayed behind his eyes in vivid, merciless detail—the sounds, the blood, his own face.
Yui's hand shot out and grabbed his sleeve. "Ren? Ren! Hey, what's wrong? You just went completely pale. Are you okay?"
He could barely hear her over the roaring in his ears. "I'm… fine," he forced out, voice hoarse and cracking. "Just… dizzy. Low blood sugar, maybe. It happens sometimes."
She frowned, genuine worry etching her features. "You look like you're about to throw up. Seriously. Let's sit down for a second. I can run to the vending machine and get you water—"
"No." The word came out sharper than he intended. He swallowed hard, fighting the nausea already rising in his throat. "Just… let me walk you home. All the way. It's getting dark earlier these days. Safer."
Yui blinked, surprised by the intensity in his voice, then gave a soft, slightly confused laugh. "Whoa, protective big brother mode? That's new. Alright, Mr. Mysterious. I won't complain about the escort."
They continued walking. Ren's mind raced faster than his feet. The vision felt immediate—like tonight. The sky was already deepening into bruised purple, and fat raindrops had begun to fall. He scanned every shadow, every alley entrance, every passing stranger with paranoid intensity. His palms were slick with cold sweat. He kept his gaze fixed downward, avoiding reflections in shop windows, avoiding anything that might trigger the ability again.
But he couldn't avoid Yui.
She was right there beside him—warm, alive, laughing at her own silly jokes about the math teacher's terrible handwriting. The girl who had refused to let him fade into nothingness. The only person who saw him.
He wouldn't let the vision win.
They turned onto the familiar narrow side street that cut behind the konbini. The exact route from the vision. Rain was falling harder now, drumming steadily on rooftops and pavement. The streetlight at the alley entrance flickered once, then twice—exactly as he had seen.
Ren's stomach twisted violently. "Yui, stop. Let's take the long way around the main road. Please."
She tilted her head, ponytail dripping with rain. "It's literally thirty seconds faster this way. You're acting really weird today, you know that? Did something happen in class?"
Before he could pull her back, a hooded figure stepped out from the mouth of the alley.
Knife already drawn, glinting dully in the flickering light.
Time fractured.
The attacker lunged—not at Yui first, but straight at Ren, as if his interference had altered the sequence. Ren shoved Yui roughly behind him. The blade sliced across his forearm instead of his throat, a burning line of fire that made him hiss in pain. Blood welled up instantly, soaking his sleeve.
Yui screamed.
The man spun with terrifying speed. The first stab found her stomach—just like the vision. The wet, meaty thunk echoed in Ren's ears as the knife sank deep. Blood exploded outward in a hot spray, splattering across Ren's chest, neck, and face. Yui's eyes met his again—wide with shock, pain, and a heartbreaking flash of confusion, as if she couldn't understand why this was happening while he stood right there.
The second stab drove between her ribs. She coughed violently, red foam bubbling on her lips. Her legs gave out.
Ren caught her as she fell, both of them crashing to the wet pavement. The attacker ripped the knife free with a sickening squelch and fled into the rain, footsteps splashing away.
Ren didn't chase. He couldn't.
Yui trembled violently in his arms, blood pouring from her wounds in thick, pulsing surges with every weakening heartbeat. It soaked through his uniform, coated his hands like warm gloves, and ran down his cheeks mixed with rain.
The metallic stench overwhelmed him—the exact smell from the vision.
"Ren…?" Her voice was a broken, wet whisper, barely audible over the rain. "It… hurts… Why is it… so cold…?"
He tried to speak, to tell her to hold on, to promise everything would be okay. But his throat had closed completely. All he could do was press his hands uselessly against her wounds, feeling her life slipping away between his fingers.
Her fingers clutched weakly at his sleeve one last time… then went limp.
Her eyes—those bright, stubborn eyes that had always found him in a crowd—stared up at him, empty and glassy.
She was gone.
Ren sat frozen on the cold, blood-slick pavement, unable to move a single muscle. Rain hammered down on them both. Sirens wailed somewhere in the distance—someone must have heard the scream—but they were too late. Far too late.
The horror finally broke through.
He lurched sideways and vomited violently onto the street. Once, twice, three times, until nothing remained but burning acid and raw, choking sobs. His entire body shook uncontrollably. Blood—her blood—covered his hands, his face, his clothes. He could still feel the warmth of it fading against his skin.
The vision hadn't been a warning.
It had been a promise.
And by trying to change it, he had only ensured it happened right in front of him—while he watched, helpless and drenched in her blood.
