The training ground buzzed with the hum of chakra and the clatter of kunai. Naruto wiped sweat from his brow, his scar throbbing like a second heartbeat. Across the field, Kiba and Shikamaru sparred, their laughter grating against his frayed nerves.

"Focus, Naruto!" Iruka barked, tapping the target dummy with his scroll. "Channel your chakra smoothly."

Naruto gritted his teeth. Smoothly. Right. He formed the ram sign, but the moment his chakra surged, the scar ignited. Golden light spiderwebbed across his cheek, casting jagged shadows on the grass.

"Freak," someone whispered.

The dummy's head exploded in a shower of splinters. Naruto staggered back, clutching his face as the class fell silent.

"Enough for today," Iruka said quietly, avoiding his gaze.

Midnight – Naruto's Apartment

The nightmare began with ash.

Naruto stood in the ruins again, Kakashi's broken mask in his hands. The golden-eyed beast loomed, its tails carving trenches into the earth. "You're mine," it growled—in Minato's voice.

"NO!"

He woke mid-scream, tangled in sweat-soaked sheets. Moonlight streamed through the window, but the room felt wrong. Too quiet. Too cold.

Then he noticed the rooftop tiles under his palms.

"How…?"

The Academy rooftop stretched below him, Konoha sleeping soundly under the stars. A chill wind bit through his pajamas.

"Impressive," a voice drawled.

Sasuke leaned against the weathervane, arms crossed. "Teleportation jutsu? Or just another demon trick?"

"Shut up!" Naruto snapped, scrambling to his feet. The scar flickered, betraying his panic.

Sasuke's eyes narrowed. "Whatever you're messing with—it's leaking. Even the Uchiha archives warn about tampering with spacetime. You'll tear this village apart."

"I said shut up!" Naruto's fist connected with Sasuke's jaw before he could stop himself.

Sasuke spat blood, smirking. "Hit a nerve, deadlast?"

The scar flared gold, and the world twisted—

Konoha Prison – Hour Before Dawn

The Third Hokage stared through the barred window of Mizuki's cell. The traitor crouched in the corner, rocking back and forth, his fingernails raw from scratching the walls.

"Golden eyes… in the void… it followed him back…"

"What did you see, Mizuki?" the Hokage pressed, voice steel. "What attacked you?"

Mizuki lunged at the bars, eyes wild. "It did! The thing that lives between worlds! It tried to claw its way through the brat—said it'd devour us all!" Spittle flew from his lips. "You think the Nine-Tails was a monster? That thing is a god!"

The Hokage's pipe trembled in his hand. "And Naruto?"

"A bridge!" Mizuki cackled. "The Fourth made him a bridge—and they're crossing!"

Naruto's Bathroom – Dawn

Naruto splashed water on his face, avoiding the mirror. The scar's glow had dimmed, but the weight of Kakashi's mask under his pillow haunted him. A better monster.

He glanced up—

The mirror cracked.

A figure loomed in the fractured glass: tall, bone-pale, with horns curving like crescent moons. Its golden eyes burned, pupils slitted like a serpent's.

"Hello, little bridge," it whispered, voice echoing from a thousand worlds.

Naruto's breath fogged the glass. "What… what are you?"

"Hungry."

The faucet exploded, water spraying like blood. Naruto stumbled back, but the reflection's hand pushed through the glass, clawed fingers grazing his scar—

"HOKAGE-SAMA! IT'S MIZUKI—HE'S DEAD!"

The shout from the street shattered the moment. The creature hissed, dissolving into mist as the mirror shattered.

Hokage Tower – Secret Archives

The Third Hokage ignited the scroll with a trembling flame. Project: Yūkai curled into ash, its secrets dying with the smoke.

"Forgive me, Minato," he murmured, watching the classified files burn. "Some bridges should never have been built."

Outside, dawn broke over Konoha. The spiral-and-crescent symbol on Minato's monument gleamed faintly in the light.

The next morning, Naruto found a single clawed golden feather on his windowsill.
