In Another World With Omnitrix

The late morning sun filtered through the apartment blinds as Riven sat cross-legged on his bed, the Omnitrix glowing faintly on his wrist.

"Silent mode," he said firmly.

A low hum answered.

"Voice command access limited. Minimum ten alien DNA profiles required."

He narrowed his eyes. "Yeah, yeah, you said that."

He had tried various combinations all morning. Voice tones, gestures, even mimicry of old Omnitrix activations. Nothing had worked—until, suddenly, the glow dimmed, and the emblem stopped pulsing.

The familiar ping of transformation feedback—gone.

"...Huh." He tapped it lightly. No voice. No beeping.

Finally, silent mode engaged. It wasn't full command override, but it would keep attention away. No more noisy countdowns. No accidental transformations.

He slid his sleeve down over the device and stood. His phone buzzed right on cue.

Lyra Veyla: "I found something. You free to investigate?"

He raised a brow and typed back:

Riven: "Define something."

Lyra: "New dungeon. Minor disturbance, outskirts of your district. Low activity readings, probably safe. Thought you might want in."

Riven: "...Sure. Where?"

Lyra: "I'll text the address. Also, change your damn clothes. You've got money now, remember?"

He chuckled dryly and checked his reflection. Yeah, he still looked like a lost vagrant from the apocalypse. A new outfit wouldn't hurt.

...

Two Hours Later – Edge of District 7

District 7 had its own rhythm—urban, alive, and humming with static energy from relic-powered billboards. The streets were clean, the crowds busy, and yet the back alleys felt like forgotten pockets of mystery.

Riven spotted her waiting near the alley mouth. Lyra leaned against a metal support pillar, her long slate-gray coat fluttering faintly in the breeze. Her glasses caught the sunlight, and her silvery-white ponytail shimmered like frost.

"You changed," she said, eyeing his sleek new black jacket and boots. "No more 'urban survivor' aesthetic?"

"You told me to," Riven replied.

"I also told you to bring coffee."

"You didn't and you don't get both."

She smirked and pushed off the pillar.

They started walking toward the old subway station entrance, their steps steady. The silence stretched comfortably until Riven broke it.

"So… why me? You didn't have to invite me."

Lyra cast a sideways glance, amused. "You said it yourself: low profile. This one's off the radar. Thought you'd want the experience."

He raised a brow.

"And," she added with a subtle grin, "I wanted to see that Nullshift thing you mention. You made it sound dramatic. I figured I deserved a live demonstration."

Riven sighed. "You sure know how to make curiosity sound charming."

"I get that a lot," she replied with zero shame.

....

They approached the abandoned subway line, its rusted signage flaking. The air shimmered ahead—classic dungeon formation. A softly rippling gate, bluish with faint energy pulses. Standard entry.

Lyra examined the gate. "Stable, low threat signals. Nothing that screams trouble."

Riven didn't look convinced. "That's what everyone said before stepping into the frozen horror show."

"This time, I brought a firestarter," she teased.

He gave her a dry look. "Ice affinity, right?"

She nodded and let a wisp of frost curl from her fingers. The chill made the air dense for a split second before fading.

"Never seen a cold-type hunter up close," he muttered.

"Stick around, mystery boy. I'm full of surprises."

...

Inside the Dungeon-

The moment they crossed the threshold, the atmosphere changed.

Cold hit first—deep, biting cold. This wasn't the natural chill of an ice dungeon. It was different.

Cracked stone floors veined with frozen rivers sprawled before them. Crystalline structures jutted from walls like jagged teeth. Every sound felt muffled, swallowed by the sheer weight of the silence.

Riven's breath misted out as he looked around. "This doesn't feel like a C-rank."

Lyra didn't answer at first. Her expression had shifted. Serious and Focused.

She finally muttered, "This isn't what it was supposed to be."

The Omnitrix remained dormant, but Riven felt it vibrate faintly. It sensed something.

He scanned the terrain cautiously, noting ruined machinery partially buried in frost. A broken pillar nearby had alien markings—ones that echoed the ancient designs he'd seen before. This place was old.

"See anything familiar?" she asked, tone lighter but edged.

"Not yet," he replied honestly. Then muttered, "But it feels familiar."

.....

A low sound—like distant thunder—echoed from behind them.

WUUUUUMMMM—

Both turned sharply.

The dungeon entrance glowed—then flickered. Its once blue hue darkened. Now a deep crimson, like blood smeared over cracked glass.

It pulsed once. Then again.

The portal sealed.

Gone.

The silence that followed was louder than any alarm.

Lyra's eyes narrowed behind her glasses. "That's not a good thing."

The frost at her boots thickened instinctively.

Riven said nothing, his fingers unconsciously drifting toward the Omnitrix. It hadn't reacted yet. Not fully.

But deep within its matrix… something stirred.

Chapter 14 End.
