The Underflow archive wasn't a majestic library of glowing tomes and floating bookshelves. It was a chaotic labyrinth of frozen moments stacked like messy Jenga towers in a flooded basement that smelled of old paper, mildew, and the faint metallic tang of time that had gone sour. Violet light pulsed from cracks in the ceiling like cheap club lighting that had been possessed by angry spirits. Shelves leaned at dangerous angles, filled with shimmering shards that played brief, looping scenes when touched — a couple's first kiss on the Han River bridge, a salaryman missing his train by three seconds, someone's disastrous noraebang performance where the high note turned into a scream.
Haruto, Echo, and the Mirror Keeper moved through the narrow aisles, footsteps echoing strangely. Veil had sent two shadow-binder escorts — a quiet guy named Kai who kept chewing on glowing jerky (the non-traumatized kind) and a woman named Mina who kept complaining about the "damp vibes" ruining her hair.
"This place gives me the creeps," Mina muttered, adjusting her silver net scarf. "Last time I was here, a memory shard tried to sell me my own awkward middle-school confession. I still have emotional whiplash."
Kai shrugged, crunching loudly. "Better than the jerky that started mooing last night. Thanks for that, by the way, half-moon."
Haruto rubbed the back of his neck, face heating up. "I said I was sorry. It was an accident. The beef had issues."
Echo snorted, moonlight knife spinning lazily in her hand. "You gave beef PTSD and now you're apologizing to the jerky. Only you, Takeda."
The Mirror Keeper floated ahead, her white hanbok untouched by the damp. She occasionally reached out to gently redirect a drifting shard that tried to latch onto Haruto like a clingy ex.
They reached the central chamber — a circular room where the journal had promised the full prophecy would reveal itself. The walls were lined with larger mirrors, each one reflecting a slightly different Seoul: one under eternal rain, one burning under a red moon, one eerily empty of people. In the center stood a low stone pedestal. Haruto placed the journal on it.
The moment the cover touched the stone, the book flipped open on its own. Pages rustled like impatient wings. Ink bled across the paper in his father's hurried script, kanji and Hangul mixing in a frantic dance.
Then the mirrors ignited.
Light exploded outward. Every shard and mirror in the archive flared violet. Haruto's eyes fractured wider than ever, layering past, present, and futures in a dizzying storm. He saw his father — Takashi Takeda — standing in this exact room years ago, blood streaming from identical violet cracks, newborn Haruto bundled in his arms while Eun-ji clutched the baby like a shield.
The Warden's projection loomed in the background, charcoal coat pristine. "You cannot hide an anomaly forever, Takeda. The river will correct itself."
Takashi's laugh was broken glass. "He's my son. Not your correction." He raised the black-flame blade — the same one now resting against Haruto's ribs — and tore a hole in time itself. "I'll seal it with this. But the blade stays with him. When the red moon rises, he'll need it more than I did."
The vision shifted, faster now.
Haruto saw the full prophecy unfolding like a bad manhwa cliffhanger:
When the red moon rises over the Han, the Fracture bearer will stand at the center. He may seal the river's hunger with the blade… or become the hunger itself. The half-blood mistake will either save Seoul or unmake every timeline that ever loved him.
New lines appeared beneath it, fresh and bleeding:
The river does not forgive debts. It only collects. The half-moon carries the key and the lock. If he chooses mercy, the city lives. If he chooses power, everything fractures. There is no third path… unless the mistake learns to laugh at the bill.
Haruto staggered back, gasping. The melancholy hit like a truck — heavy, cold, familiar. But underneath it, that stubborn spark of humor flickered again. "Great. So I'm either the hero who saves everyone or the villain who ends everything. No pressure. And the river wants me to laugh at the bill? What is this, cosmic stand-up comedy?"
Echo steadied him with a hand on his shoulder. "Your dad had a dramatic streak. But he also left you the blade and the journal. He believed you could find a third way."
Kai crunched another piece of jerky. "Or he was just bad at math. 'No third path' sounds like classic prophecy cop-out."
Mina flicked a shard away from her hair. "Can we focus? The red moon is already low on the horizon. I saw it last night — blood-red, cracking the sky like cheap glass. Hunters are getting bolder. One tried to order soju at my favorite stall wearing a halmeoni's face. Creepy as hell."
The archive groaned suddenly. The mirrors rippled violently. One by one, they cracked wider, white-eyed hunters stepping through the glass like it was water. Dozens this time — wearing faces of subway passengers, street vendors, even a few familiar pojangmacha regulars.
"Anomaly located," they droned in unison, voices layered like the worst group karaoke ever. "The prophecy has been read. Surrender the blade or we unmake the half-blood's mother in every timeline."
Haruto's scar split open. Black threads surged down his arms like living gauntlets. The blade ignited with cold fire. "You guys really need better material. 'Unmake the mother' is so last chapter."
Echo laughed despite the danger, knife flashing out. "That's my line-stealing half-moon. Let's give them a show they'll never forget — mostly because they'll be dust."
The fight erupted in the archive like a time-warped bar brawl. Haruto bent an entire minute, slipping between hunters while rewinding their strikes. One hunter lunged at him with claws extended; he merged two futures — dodging left while striking right — and the black-flame blade carved through its chest, unraveling it backward into a cloud of tourist selfies that dissolved mid-flash.
The river took its toll — ten full days gone. Haruto felt another chunk of ordinary life vanish: a quiet walk with his mother along the Han, gone before it could happen. But he kept moving, the blade singing louder, the black threads reinforcing every swing.
Echo carved through two hunters with graceful arcs of moonlight, yelling, "This one's for the beef PTSD!" as she rewound a fatal blow on Kai.
The Mirror Keeper raised her palms. Reflective shards exploded from every mirror, spinning like a deadly disco ball. Hunters were sliced, peeled, and reflected back at themselves until they screamed in static.
One hunter broke through and grabbed Mina. Haruto rewound the attack, black threads yanking the creature away and slamming it into a shelf of memory shards. The shelf exploded in a cascade of embarrassing moments — someone's bad haircut, a failed proposal, a noraebang disaster where the singer hit the high note and the mic feedback made everyone cry.
Kai laughed through the chaos, jerky still in mouth. "Best archive party ever! Someone queue the trot music!"
Haruto couldn't help the tired grin that broke across his face. Even as the river drained more of his future, the ridiculousness of fighting cosmic horrors while surrounded by floating bad karaoke memories kept the melancholy from swallowing him whole.
The last hunter dissolved with a final, garbled "The red moon comes—" before turning to dust.
Silence fell, broken only by heavy breathing and the soft hum of settling shards.
Veil's escorts high-fived. Echo wiped sweat from her brow, grinning. "Not bad, half-moon. You turned a prophecy reading into a comedy special. The river's probably filing a complaint right now."
The Mirror Keeper floated closer, her endless violet eyes soft. "You laughed again. The river hates that. Keep doing it."
Haruto sheathed the blade, chest heaving. The journal on the pedestal had gone quiet, but he knew the words were burned into his mind now.
The red moon prophecy was clear: seal the hunger or become it. No third path… unless the mistake learned to laugh at the bill.
He looked at his fractured allies — Echo with her sharp grin, the Mirror Keeper with her quiet mischief, Kai still chewing jerky like nothing had happened, Mina fixing her hair while complaining about "time-static frizz."
For the first time, the weight on his shoulders felt shared.
The red moon was rising faster now, blood-red and cracking the night sky like his own eyes.
Hunters would come again, hungrier and with worse one-liners.
But down here, in the damp archive beneath Seoul, a half-blood boy with a sword that ate futures and a scar that refused to stay closed had friends who fought like the world might end but the after-party — complete with traumatized jerky and bad karaoke memories — was still mandatory.
Haruto allowed himself one more tired, crooked smile.
"Let the river send its bill," he muttered. "I'll pay it with interest… and maybe a side of stand-up comedy."
Echo overheard and laughed brightly. "That's the spirit. Just don't make the beef cry again. We have enough emotional support livestock as it is."
As they made their way out of the archive, the red moon's faint red glow filtered through a crack in the ceiling far above, painting the violet light a bloody hue.
The future was coming.
But tonight, at least, it would have to wait while a tired anomaly and his broken friends shared a moment of ridiculous, stubborn joy in the face of cosmic accounting.
The river could bill him later.
He still had jokes left.-school confession
