Supervillain Idol System: My Sidekick Is A Yandere

Medusa's frown was immediate, her brows pulling tight as her eyes flicked toward Winter. The android's words weren't what made her uneasy—it was the way she said them.

That calm, measured tone, as if nothing about this moment carried any weight. As if Medusa herself was already an afterthought.

Her fingers curled slightly at her sides.

'That bastard Harold said there were no superhuman threats here,' she thought, her gaze hardening. 'Let alone a powerful android…' Her jaw clenched, the anger settling in deep. 'He set me up.'

Medusa's lips pressed into a thin line as the realization burned through her. Her caution shifted to irritation, then to something sharper. Her mind sorted through options, debating whether to cut her losses now or—

A low grunt caught her ear.

She turned slightly, her gaze landing on Egor as he pushed himself fully upright, one hand still pressed against his stomach. His breathing was heavy, but he wasn't down—not yet.

'No, it's too dangerous. We should—'

"Time's up." Winter's voice interrupted her thoughts.

Medusa's stomach dropped. She snapped her gaze forward, already knowing what she'd see.

Winter was airborne.

Her body moved with deadly precision, no wasted motion, no hesitation. Winter's foot was extended in a powerful arc, and Medusa—whose ability was useless against machines—was wide open.

Her eyes widened. She couldn't block. She couldn't dodge.

Then—

**THOOM!**

A blur of motion. A sudden impact.

Winter's strike never landed.

Pantheress had intercepted, launching from her position with a devastating kick of her own. The two attacks met mid-air with a force that rattled the night—Pantheress's powerful legs against Winter's unyielding frame.

The clash sent Winter hurtling sideways, the shockwave kicking up a gust that rustled the trees and scattered loose dirt across the yard.

But she wasn't down.

Winter's body twisted mid-flight, her limbs moving at unnatural angles to correct her trajectory. She landed in a low crouch, her head tilted slightly, her expression unshaken.

Pantheress landed lightly in front of Medusa, standing tall as she took in the sight before her.

Rather than concern, her pupils shrunk with excitement, a slow, eager grin spreading across her face.

"Oh, you'll be very fun to play with."

Medusa recognized the shift in her tone immediately.

"Wait, don't—"

Too late.

Pantheress launched forward, her body a blur as she rocketed toward Winter, another powerful kick already in motion.

Winter remained still, her composure unchanged. Her eyes tracked the incoming attack, but she made no move to avoid it. Instead, she allowed Pantheress to close the distance—allowed the kick to seem as though it would land—

Then, at the last second, she caught it.

**BOOM!**

The impact shook the ground, the sheer force of Pantheress's strike sending cracks through the dirt beneath Winter's feet. But Winter didn't stagger. She slid back slightly, her heels carving lines into the soil, yet her stance remained unbroken.

Pantheress's eyes widened.

Winter still had her leg.

Pantheress yanked her foot back, breaking free just as she leaped into the air, twisting into a roundhouse kick.

Winter didn't bother countering. She didn't need to.

Her frame blurred.

In an instant, she ducked, the strike missing entirely. Before Pantheress could recover, Winter's hand shot out, grabbing her by the tail.

Pantheress barely had time to register what happened before Winter pulled.

**CRACK!**

The punch to her face was brutal, her head snapping back from the force. But Winter didn't stop there. Using the tail for leverage, she yanked Pantheress forward again—this time delivering a devastating kick.

The impact sent Pantheress flying.

Her body slammed into the yard, skidding across the grass before colliding with the pavement walkway. Dust and chunks of dirt sprayed into the air, a long trench left in her wake. She didn't stop moving until her back hit the fence with a heavy **thud**.

Medusa shielded her eyes from the flying debris, but she barely had time to process what had happened before she heard it.

**BOOM**

She snapped her head forward.

Winter was already attacking again.

Medusa's breath caught—she could feel the force rushing toward her—

Then—

**CRACK!**

Egor was in front of her. His massive arms were raised, both hands catching Winter's kick.

A sharp, sickening sound followed. Bone cracking.

Egor grunted, his expression twisting in pain, but his stance held firm.

Then his grip tightened. "RAAGHHH!"

With a furious roar, Egor swung.

Winter's frame was made of lightweight alloy—strong, but easy to throw. And Egor, despite the injury, still had raw strength on his side.

Winter was airborne again.

She hurtled toward the house, her body twisting mid-flight, adjusting even as she neared the porch.

Medusa's stomach turned.

This was their only chance.

"We need to leave. Now!"

Her voice carried urgency, but her gut told her one thing—if they didn't move immediately, there wouldn't be a second opportunity.

Medusa didn't hesitate.

The second Egor's throw sent Winter flying, she turned on her heel and bolted for the SUV parked out front. Her boots hit the pavement hard, each step quick.

Behind her, Egor followed, his heavy footfalls shaking the ground with every stride. His breathing was rough, the pain from his fractured bones evident, but he didn't slow down.

Pantheress, still near the fence, locked eyes with Winter.

She frowned. She knew when to cut her losses. Winning wasn't impossible, but it wasn't guaranteed, and that was enough.

With a sharp inhale, she crouched and then—

**WHOOSH!** Her body shot away from the property, a blur of muscle and speed.

Just as she disappeared into the darkness, Winter landed on the porch.

**CRRRRK!**

The wooden planks beneath her feet buckled, long cracks spiderwebbing outward from the impact. Splinters popped free, some snapping in half, others barely hanging on. The entire structure groaned under the force, but it held.

Winter straightened, her body fluid, controlled. Her glowing red eyes flickered, scanning the area, her systems recalibrating for immediate pursuit.

Then she stopped.

Her frame stilled mid-motion, one foot slightly raised, ready to propel forward—but she didn't.

Her field of vision was clear. No threats remained on the premises.

Her processors ran the calculations instantly. The three intruders were still visible, still scrambling into the SUV, still an easy target. One well-timed leap and she could intercept before they got far.

But that wasn't her objective.

Her protocols were specific. Protect the property. Neutralize threats on the premises.

Now, there were none.

Her glowing red eyes faded back to blue. Her muscles loosened. The aggressive stance she'd held since the fight began melted into something passive, almost indifferent.

Winter stood there in silence, watching as the SUV roared to life. The headlights flared bright, and a second later, the tires screeched against the pavement.

The vehicle shot down the road.

Winter made no move to stop it.

But she wasn't done.

Lifting a hand, she brought her fingers to her right eye, pressing lightly at the outer edges of her lower eyelid. The skin, synthetic and impossibly smooth, responded to the pressure. A subtle shift, barely perceptible, ran along the seams of her face.

Her fingers moved with care, applying gentle force until—

**Click**

Her right eye pushed forward, extending slightly from its socket.

The glossy surface of her iris shimmered as the metallic nerves beneath it began to move. They uncoiled in a controlled sequence, thin tendrils shifting and rearranging with eerie synchronicity.

A small, seamless opening formed where the eye once sat.

Then—

The entire structure detached.

Her eye disconnected completely, but the nerves didn't retract. Instead, they twisted, reshaping into something new.

In a single fluid transformation, the metallic strands tightened, forming two small, sharp-edged propellers. They whirred softly, testing their rotation speed, before coming to a controlled hover.

The detached eye floated midair for a moment, adjusting, stabilizing itself in the windless night.

Then—

**Bzzzzzt!**

It zipped off, moving through the air at a rapid pace, seamlessly adapting to its new function.

Winter lowered her hand.

"Tracking the vehicle now," she stated calmly.

Her gaze remained fixed on the road ahead, her mind already processing the incoming data stream.

The fight was over.

But the hunt had begun.
