In Another World With Omnitrix

The walls of crystal groaned as the dungeon began to collapse around them, slowly dissolving into shimmering mist. The shattered remnants of the boss's crystalline throne crumbled away, the final echo of the battle fading like a breath caught in time.

Riven stood motionless, Nullshift hanging heavy at his side, drained. He could still feel the heat of the blaster's last pulse reverberating through his bones. Every muscle ached. His hoodie was torn. The Omnitrix on his wrist was dim, but the faint green pulse at its center told him everything had worked. Diamondhead's DNA had been absorbed. Silently. Successfully.

He didn't smile, but there was a faint flicker of satisfaction in his eyes.

Lyra stood beside him, her breathing calm but shallow. Frost still clung to her fingers, residual mana trailing off her like steam. Her expression remained unreadable, though there was a quiet sort of pride behind the tiredness.

"That's it," she whispered. "We survived."

Riven managed a grunt, wiping a smudge of crystal dust from his cheek. "Barely."

She glanced at him. "You're still on your feet. That's impressive enough."

The dungeon trembled again, and ahead of them, the air shimmered. A golden rift peeled open—horizontal, low and wide. The exit gate. The final threshold.

Lyra turned to Riven and said softly, "Use it."

He blinked at her. "The relic?"

She nodded. "You've got less than five minutes. The suppression relic only works if you activate it before the system finishes its sync."

Riven reached into his coat and retrieved the smooth, disk-shaped relic she'd given him before—the one she'd handed him without fanfare. A soft glyph shimmered on its surface as he pressed it against Nullshift.

There was a gentle hum. A faint pulse of mana spread through the air—and then silence.

Nothing happened. Nothing visible, anyway.

"...Did it work?" he asked cautiously.

"We'll only know once we step through," Lyra replied. "The system doesn't announce clears while we're still inside. Only after full exit. That's when it syncs to your profile."

Riven swallowed hard. "And if it doesn't work?"

She looked at him, steady. "Then Nova Arcanum will wipe the records. But that's messier."

With no further words, they both stepped toward the golden gate, the only stable surface left as the dungeon's geometry unraveled behind them. Riven's body screamed for rest, but he moved forward, driven by sheer force of will.

As they passed through the gate, the world twisted—light folding inward, gravity shifting—and they emerged into the night.

The air was cold and still. A broken section of an abandoned subway tunnel yawned around them. Debris scattered across old rails. The artificial lights flickered faintly in the distance, long since drained of power.

No one was there to greet them.

Riven instinctively flinched, waiting for the notification.

But none came.

No announcement. No Hunter System alert. No broadcast about an A-rank dungeon being cleared.

He let out a slow breath. "It worked."

Lyra nodded, though her eyes remained alert. "Seems like it."

The weight of the silence pressed down harder than any alarm could have. No cheers, no crowd, just empty air and the soft hum of collapsing magic behind them.

Riven took a single step forward.

Then his knees buckled.

"Riven!"

He collapsed—but didn't hit the ground. Lyra caught him, bracing his weight with one arm, gently lowering him to sit against a broken rail.

His eyes were dazed, half-lidded. "Guess I… really did burn it all."

"You idiot," she muttered, brushing his bangs from his forehead.

He tried to smile, but it didn't reach his lips. "Did the relic really hide the sync?"

She smiled faintly. "You'll know once you're awake again."

His breathing slowed. And within seconds, he was unconscious in her arms.

She looked down at him and whispered, "You look cute when sleeping, huh."

A long moment passed. Then she added under her breath, "And heavier than you look."

Later – Nova Arcanum Private Facility, Underground Sector 3--

A sterile room hummed softly with ambient energy. Pale blue lights pulsed along the corners, woven into the mana-insulated walls. It was quiet, private, the kind of place reserved for emergency recoveries, hidden far from guild records.

Riven lay on a diagnostic table—not hooked up to anything invasive, just resting. His breathing was calm. Nullshift remained affixed to his arm, dim but slowly pulsing. The Omnitrix stayed in silent mode, its surface almost cool.

He stirred.

Blinking slowly, he winced and sat up, groaning softly. "Ugh… what hit me…"

A voice responded, calm and familiar. "A crystal monster, a collapsing dungeon, and your own stubbornness."

He turned his head.

Lyra stood in the doorway, arms crossed, now wearing her usual gray overcoat. She walked over, handing him a glass of water.

"You're in one of Nova Arcanum's shadow wards," she explained. "It's not on any registry. And no, no one tracked us. We're clean."

Riven sipped the water, letting it cool his throat. "How long was I out?"

"A few hours."

He gave a low whistle. "Guess I needed it."

She nodded. "You did well. Nullshift's blaster form burns energy fast. You weren't ready for the cost."

"Five shots," he muttered. "Then it reverts."

"And you didn't know that beforehand?" she asked, a teasing edge to her tone.

"I do now."

Her gaze lingered on him a moment longer. Then she turned to leave.

Riven leaned back against the pillow. "Lyra."

She paused.

"Thanks… for bringing me here."

She glanced over her shoulder, offering him a genuine—if small—smile.

"Just don't die before I figure out what else you're hiding, Riven."

The door closed softly behind her.

Silence returned.

Then, beneath the covers, the Omnitrix pulsed once—soft and steady.

Diamondhead was waiting.

End of chapter.

Thank you for reading.

I know some changes might be there because I kept forgetting some of it and need to recheck and even check other chapters.
