North Jeolla Province – Mountain Pass, 4:17 AM

A military convoy rolled quietly through fog-soaked hills—four armored vehicles transporting a prototype called NEXUS CORE: a neural stabilizer designed to regulate synthetic strength surges.

They never saw her coming.

Do Reika dropped from a cliff, landing on the lead vehicle like a falling star.

Steel buckled under her boots.
Her fist cracked the windshield like a thunderclap.

The driver didn’t stand a chance.

Within seconds, she’d ripped the vehicle apart and seized the core—before the rear units could even react.

One soldier managed to activate a distress beacon before being thrown into a tree.

Reika paused only once… to look up at the rising sun.

“Let them come.”

Legacy HQ – Command Room

Red alerts. Real-time feeds. Military emergency channels flooding in.

Do Rin read the report, eyes narrowing.

“One attacker. No known signature. Matched my vitals by 93%.”

Jae looked up from the analysis terminal. “She didn’t just take the NEXUS CORE. She activated its failsafe. That core is now linked to her neural network.”

“Meaning?”

“She can override enhancements. Globally.”

Silence.

Rin’s voice dropped.

“We find her. Now.”

Do Rae sat outside the medical wing at Legacy HQ, her hands wrapped in gauze. Jin Seok stood nearby, watching her quietly.

“You okay?” he asked.

She nodded.

“Just cracked three ribs on a guy who used to mean something to me.”

“Used to?”

She met his eyes.

“There’s no part of me that regrets walking away from Tae Jin.
But part of me still hates the girl who stayed too long.”

Jin Seok crouched in front of her.

“She’s not here anymore. Just you. Strong, stubborn, and way out of my league.”

She managed a small laugh. Then leaned in and kissed him—slow and certain.

“Guess you’re stuck with me now.”

“Happily.”

Legacy Ops – Briefing Room

Rin laid out the plan.

“Reika’s headed east. She’s drawing us out.”

“To what?” Kang Jae asked.

“To a confrontation. She doesn’t want domination. She wants to prove something.”

“Like what?”

Rin didn’t hesitate.

“That she’s the real legacy. Not me. Not Rae. Just her.”

The team assembled: Rin, Rae, Jin Seok, Kang Jae, Ji Woo, and a tactical strike unit.

As they geared up, Rae looked at her sister.

“Think we’re ready?”

Rin’s expression was unreadable.

“We’re not.”

Pause.

“But we’re enough.”

They bumped fists.

“Let’s end this.”
