Supervillain Idol System: My Sidekick Is A Yandere-Chapter 515: The Havenridge Incident (Part 7)

Chapter 515: Chapter 515: The Havenridge Incident (Part 7)

The rumbling didn’t fade.

It grew.

Stone screamed as the chamber shook harder with every passing second, the tremors stacking until the ground felt unstable beneath their feet.

Cracks raced across the floor, splitting and branching as rocks tore free from the ceiling. Dust surged up in choking waves, swallowing the light from the sphere until even its glow vanished—leaving only darkness and motion.

The rocks never hit the ground.

Vines caught them.

Dozens of them twisted upward, thick coils snapping and wrapping around falling debris, crushing stone midair as if it were nothing. Others lashed blindly, carving through dust with violent arcs as they searched for flesh.

Starboy barely dodged one that tore through the space his head had just occupied. "What now?!"

Don didn’t answer right away.

He was already moving—jumping back as a vine slammed down where he’d been, rolling as another scythed low, then vaulting clean over a third as it whipped past his legs and smashed into the wall behind him.

"Attack!" Don shouted as he landed. "Just keep attacking!"

It wasn’t strategy.

It was survival.

They didn’t have time to search. They didn’t have space to think. If they slowed, they were dead.

Don leapt again, landing on the slick surface of a rising vine. It bucked beneath him, but he used the motion, pushing off with brutal force and launching forward, threading past three whipping coils in a single bound.

A fourth snapped down toward him, thick enough to flatten a truck—

FOOSH~!

Starboy streaked past like a living projectile, his body wrapped in gold as he tore straight through the vine. It burst apart around him, shredded fibers and mucus spraying outward as he punched through and kept going.

He didn’t bother firing beams.

The coating on the vines swallowed energy too well.

So he used himself.

He carved through the mass again and again, ripping open paths through sheer momentum while Don stayed low, fast, building speed with every dodge and strike.

Each destroyed vine only fed the chaos—more erupted, more recoiled, more snapped wildly as the chamber deteriorated around them.

Then Elliot screamed.

"NOOO—MOTHER!!"

The sound tore through the space, hoarse and broken.

"I can kill them!! Let me kill them!! ARGH!!"

Don felt it vibrate through his bones.

"Look what you’ve done?! You worms!! You’ve ruined everything!!"

His voice cracked, hysteria bleeding through it.

"It was almost perfect!! Now Mother is displeased?!"

As he screamed, the vines changed.

Large and small alike began to pulse, swelling rhythmically as light flowed through them—green-white and sickly—racing along their lengths toward the ruined cocoon where Elliot was embedded. His hollow sockets flared with the same glow.

So did the hearts in his chest.

They beat.

Together.

Don felt it then.

Not from Elliot.

From behind.

His instincts snapped hard, dragging his attention to the tunnel they’d come through. Something there was wrong—building, focused, approaching.

"Keep your distance!" he yelled.

He aborted his forward charge immediately, skidding back as he continued tearing through any vine that came too close.

Starboy did the same, breaking off and pulling upward, though neither of them stopped destroying what reached for them.

The chamber shuddered again.

Then—

Every vine moved at once.

They peeled away from Don and Starboy in a single, coordinated surge, whipping around and racing toward the tunnel mouth.

Thick coils smashed together as they went, intertwining into a massive, writhing mass aimed straight at the passage.

Starboy hovered midair, staring. "What are they—"

Don didn’t answer.

Inside the tunnel, a glow appeared.

Orange.

Faint at first—then brighter, swelling rapidly as heat rolled out ahead of it. The light pulsed, flickered, then stabilized into a growing burn that painted the stone walls in firelight.

The vines rushed faster.

The glow intensified.

Something was coming through that tunnel.

And whatever it was—the vines had decided it was the real threat.

Because of this, the vines hit the tunnel like a living tide.

They slammed into the passage mouth and kept moving, piling over one another, crushing stone and earth alike as they forced themselves inward.

The orange glow vanished completely, swallowed whole beneath layers of coiling mucus coated vines. The impact shook the chamber hard enough to stagger Don, dust spilling from the ceiling in thick sheets.

Then—nothing came after him.

Don slowed, confused for half a second. No vines snapped at his legs. No coils tore up from beneath his feet. He straightened slightly, eyes locked on the tunnel behind him.

Starboy hovered a short distance above the ground, also frozen, watching the mass of vines churn and knot as if wrestling with something inside the passage.

Elliot screamed, loud and foul.

"ARGH!!! No—no no no noooo!!!"

His voice cracked into something raw and then panicked, echoing wildly through the chamber.

"Stop!! You.. You... You vile insects!!"

The vines shuddered harder. 𝒇𝒓𝙚𝒆𝔀𝓮𝓫𝒏𝓸𝙫𝓮𝓵.𝓬𝙤𝙢

Where the vines had forced their way into the tunnel, faint points of light appeared—deep orange at first, barely visible through layers of mucus-coated thick vines. The glow spread fast, crawling along the vines themselves.

They began to swell, surfaces blistering as the light intensified, their movements growing more frantic.

Stone groaned.

The vines tore at the tunnel walls as if trying to pull free. Then—

BOOM~!

An explosion ripped outward in a violent surge, shredding vines into burning fragments and flinging them across the expanse. Fire and light blasted free in a cloud, rock vaporizing at the center as debris tore through the air violently.

From the heart of it, something shot forward.

Pyro.

He burst out like a falling star dragged sideways through the earth, his body wrapped in layered fire.

Closest to his skin burned a deep blue-white core, so bright it hurt to look at, wrapped by bands of violet and blazing white, then encased again in roaring orange flame that exploded outward with every movement.

Heat bent the air around him into a glowing sphere, a blazing trail streaming behind as he tore through the chamber—not like a missile.

But a comet.

And his path was straight for Elliot.

What remained of Elliot’s face twisted, brows lifting unnaturally as surprise broke through the distortion. His glowing sockets fixed on Pyro, the sight clearly not part of whatever plan had been unfolding.

Don didn’t hesitate.

He turned and sprinted.

Stone cracked beneath his feet as he surged forward again, muscles burning as he pushed harder, faster in short bursts.

Starboy reacted at the same moment, pulling upward and then diving, coming in from above with his body wrapped in gold.

The chamber fought back.

The floor split open in places as more vines erupted, ripping through stone in violent bursts. Coils lashed at all three of them at once.

Pyro didn’t slow.

Vines that reached for him never finished the motion—burning away mid-snap, reduced to blackened husks before they could touch him. Fire rolled off him in waves, leaving scorched trenches in the ground where fragments fell.

Starboy carved through the air, smashing through anything that rose into his path, his momentum shredding vines apart in bursts of pulp and debris.

Don stayed low.

He dodged.

He leapt from broken slab to slab, skidding across loose stone, twisting past whipping coils by inches. Vines tore up where he had been a heartbeat earlier, missing him as his sprint built faster and faster, every near miss feeding the pace.

The closer they drew, the more the vines shifted focus.

They surged toward Pyro.

Thicker. Faster. Entire clusters ripping free at once in desperate attempts to drag him down—but he plowed through them, fire roaring brighter as resistance increased.

Starboy was slowed briefly by sheer volume, forced to smash his way through in bursts. Don felt it too—the pressure changing, the attention pulling away from him but still insistent.

Elliot didn’t want Don near him again.

The thing inside him understood that much.

Elliot’s ruined mouth stretched wide as his glow intensified.

"You will pay for ruining Mother’s plans!!!"

His voice boomed unnaturally deep, shaking the chamber.

"You annoying little vermin!!!"

The expanse seemed to answer him.

But not the same way as before.

Instead of vines erupting upward—

They fled.

Every vine in the chamber slithered back into the ground at once, retreating with frantic speed.

Stone broken loose behind them as they vanished, leaving the floor uneven and broken, the entire space now lit almost entirely by Pyro’s blazing form.

Don felt it instantly.

Something was rong.

He slowed, boots scraping hard as he tried to stop his momentum. Starboy noticed at the same time, pulling up short midair, eyes locked on Don instead of Elliot.

Pyro didn’t stop.

He was too close.

Just meters from collision. But then—

The floor dropped out.

CRRRRACK~!

The entire expanse split open in a single violent instant. Stone fractured in every direction as the ground collapsed inward, breaking apart into massive slabs that fell away into a vast, lightless abyss below.

Far beneath, thick coils of vines writhed and twisted, layered deep within shattered earth like something waiting to rise.

The chamber became a sinking grave.
