Reborn as a side character with a system

Shadows beneath the throne.

Chapter 18

"How... How do you..."

Isabella's voice cracked, barely a whisper. She stepped back, her heel scraping against the marble, her eyes darting around the grand living room like a trapped animal searching for escape. The chandeliers cast fractured light across her face, making her look like a broken doll.

Layla stared at her. Hard. Unblinking.

Gold light began to flare around her, faint at first, then brighter, pulsing with every heartbeat. The air grew heavy, charged, dangerous. A mother's protective instinct made manifest.

"Hmm... So will you agree... Huh??? Issa... I mean Roselite?"

The voice came from the couch, soft, mumbled, half-asleep. Nolan's head turned to the other side, his face peaceful, innocent, completely unaware of the storm breaking around him.

Layla's aura vanished instantly.

She turned toward her son, the gold light dying like a snuffed candle, her eyes searching his sleeping face for... something. Anything. Finding only the soft breathing of a boy too exhausted to wake.

"It seems like brother has taken a liking to you..."

Victor's voice cut through the silence, smooth as silk and cold as winter. He walked past the frozen tableau and settled onto a single couch, crossing his legs with the casual ease of a man who had orchestrated this entire moment.

"If it weren't for that, you'd already be a goner."

He leaned back, his smile widening into something that showed too many teeth.

"But who said you would survive even if that were the case?"

A dark grin spread across his face, the grin of a man who enjoyed watching others realize they were already dead.

Isabella's heart pounded so hard she felt it in her throat, her temples, her fingertips. It wanted to leave her chest, to run away before the rest of her could follow.

"Wha..." Her voice came out creaking, rusty, barely human. "You're going to kill me?"

"No, dear..." Victor's eyes drifted to the ceiling, studying the frescoes as if admiring art. "That would be stupid of me."

He paused. The silence stretched, thin and sharp as a wire.

"But it's no matter, you're already a target to the higher-ups."

Isabella's blood turned to ice.

"But then again..." Victor's gaze dropped back to her, heavy and calculating. "Killing you would secure a lump sum of gold. Enough to pay back all the misdeeds my older brother caused over the years."

"Then get on with it."

The words fell from Isabella's lips like stones into still water.

Victor's head snapped straight, his mask cracking, just for a moment, revealing genuine surprise beneath the polished cruelty.

Isabella stood tall. Her face was dark and serious, her posture straight as a soldier's, her hands steady at her sides. The trembling girl from moments ago had vanished. In her place stood someone who had already died once and found the experience... freeing.

"Finish what your weak brother couldn't do..." Her eyes met Victor's, unflinching. "After all, it's not like I'm the only one sent here to take his head."

"What do you mean by that!?"

Ralph jumped forward, his hand on his sword, his face flushed with confusion and dawning horror.

"There are over twenty assassins in this house on the very same mission I failed..." Isabella's finger rose, pointing straight at Victor with deadly precision. "Four of them belong to you. Right?"

Layla's heart paused. Literally stopped for one terrible beat before slamming back to life.

"What do you mean by that..." Her voice was barely audible, her hands pressed against her chest as if holding herself together. "My son would never intend to take the life of his brother!"

"She's not wrong, Mother."

Victor stood, his movements fluid and unhurried.

"But neither are you, Mother."

He turned toward the shadows in the room's four corners, the spaces between furniture, the gaps behind curtains, the darkness that seemed too thick to be natural.

"You may appear."

Four shadows detached themselves from the walls. They moved like smoke given form, sliding across the floor without sound, without breath. They knelt in a perfect circle around Victor, their faces hidden behind porcelain masks, white, expressionless, nightmare faces with empty eye holes.

Ralph and Layla remained frozen, rooted to the spot by shock. Even Hilda, who had faced dragons and demons, stood cool but wordless, her composure cracking around the edges.

So many secrets. So many knives hidden in so many backs. And all of them being revealed in one suffocating moment.

"How did you know they were there...?" Victor asked, his smile returning, curious despite himself.

"Because they are below me." Isabella's voice was calm now, almost serene. "Even if I were in my room, I would locate their movements. Their breathing. Their heartbeat."

She had trained for this. Lived for this. Died for this.

"Hmmm."

Victor lifted his hand, one finger pointing at her like a death sentence.

"Attack."

The four vanished.

So did Isabella.

Steel clashed against steel in mid-air, sparks flashing where no bodies could be seen. The room erupted into chaos, furniture splintering, paintings tearing, the chandelier swinging wildly as invisible forces collided again and again.

This was an assassin's battle. Silent. Deadly. Beautiful in its brutality.

Even though no one could be seen, they could be sensed. The air itself seemed to bleed.

A body fell, thud, unconscious, mask cracked.

Another followed, crash, into the wall, leaving a spiderweb of cracks in the plaster.

Then the third dropped, gasping, clutching a wound that wouldn't stop bleeding.

Silence returned.

Isabella materialized from nothing, her hand wrapped around the last assassin's throat, her dagger pressed against the porcelain mask hard enough to draw a thin line of blood.

She held the assassin like a shield, her eyes blazing with purple flames, flames unlike any magic Nolan had shown. These were born of rage, of survival, of a woman who had been hunted for too long and had finally stopped running.

"I told you..." Her voice was low and dangerous, shaking with barely contained fury. "If you want to finish me off, then do it yourself."

She twisted the dagger, just enough to make her point.

"Not with kids."

Her eyes blazed at Victor, anger mixed with determination, hatred mixed with something that looked almost like pity. She had been where he stood. She had sent others to die in her place. And she had learned, too late, that there was no glory in blood on your hands that you didn't earn yourself.

The room held its breath.

Waiting.
