Supervillain Idol System: My Sidekick Is A Yandere

There was no fanfare when Don stepped up onto the stage.

No music. No cheers. Just the clack of his boots against the reinforced steps—each one echoing in the silence like a quiet threat.

The arena wasn't empty—technically. The VIP booth had a restrained panic, and a handful of school-affiliated drones hovered overhead, cameras humming. But the stands? Deserted.

Didn't matter.

He wasn't performing for them.

Even now, with only echoes and drones for company, he knew eyes were watching. Thousands. Maybe hundreds of thousands. Maybe more. The thought didn't bother him. If anything, he welcomed it.

Let them all see what a real villain looked like.

He reached the center of the field and let his gaze sweep across the other students. Most stood on the sidelines, clustered in vague groups—rivals by default, allies by convenience.

Some met his eyes when he looked at them. The brave ones. Or the dumb ones. A few even straightened their posture, like defiance would make them taller.

Others looked away immediately. Too fast. Like contact alone might burn them.

He didn't blame them.

The announcer's voice filtered through the arena speakers again, smooth and practiced.

"Now then," he said, "as the first to take the stage, Don Bright will receive match requests. If any student wishes to challenge him, please step forward and join him on the platform. Should multiple students wish to compete, Don Bright will select his opponent. Should none volunteer… the choice will still be his."

A pause followed. Not long, but long enough for the silence to grow teeth.

No one moved.

Eyes flicked sideways. Students looked to one another as if waiting for someone else to be brave first. Or foolish. Maybe both.

They hated Don—some of them visibly. But hate was a luxury. Sponsorships weren't.

None of them were stupid enough to be the first sacrificial lamb. Not with so much on the line.

Don didn't flinch. He didn't smirk. He just stood there, still and unimpressed, like he was reading a room full of underwhelming applicants.

'Of course no one steps up, immediately' he thought. 'They're angry, sure. But not suicidal. Not when one loss could cost them more than pride.'

But then—movement.

A single hand rose, steady and deliberate.

Don didn't need to search for the source. His eyes had already been hovering there.

'Of course it's him.'

William Barns.

Don watched without surprise as the young man stepped forward, climbing the stairs with smooth, practiced motion. No dramatic flair, no false bravado. Just calm confidence, the kind that came from never being second-best before today.

He wore the standard SHU bodysuit—black with silver inlays, form-fitted and optimized. No sponsor patch. No enhancements. Just the default gear, well-kept and worn with intention. Most smart students chose that.

You couldn't afford to look flashy if the gear didn't back it up.

William's hair was slightly disheveled, black and mid-length, like he'd skipped the morning prep just to focus. His green eyes were steady. No blink. No twitch. Just a solid gaze locked on Don.

He stood a little over six feet. Broad shoulders, athletic frame. A hero in the making. The kind recruiters drooled over.

"And there we have it," the announcer's voice rang out, slightly more animated now. "Our first match will be Don Bright… versus William Barns."

There was a subtle shift in the air.

No cheering. But the silence? It tightened.

Don didn't move as William approached the center of the stage. He didn't reach out. Didn't greet him. Just kept watching. Not assessing for threat—he already knew how this would go.

He had studied William in detail.

Top-grade C by official rankings. But word of mouth pushed him higher. B-class potential. Super strength, grade B. Durability and speed, both C. The kind of numbers that looked good on paper—and better in a highlight reel.

But there were no highlight reels for William. Not recently.

He'd stayed out of the spotlight. No major competitions since early high school. Rumor was, he'd turned down sponsorship talks just to keep his debut moment clean. Pure. Unforgettable.

Smart.

Wrong day for it, though.

William stopped a few paces away and held Don's gaze without flinching.

Don tilted his head slightly, as if weighing the air between them.

'He's good,' Don thought. 'Really good. But not good enough. Not today. Not against me.'

This wasn't about victory.

This was about control.

He wasn't here to win matches. He was here to set the tone.

And William?

William was the tone-setter's sacrifice.

William adjusted his stance the moment his boots hit the stage proper.

He didn't flinch. Didn't hesitate. But something in the way his foot shifted—slight, quick, like a recalibration—gave him away.

It felt strange to him. This wasn't supposed to be Don's moment. It was supposed to be his.

He'd studied the others. Not everyone—just the ones that mattered. The top threats. The maybe-problems. Don Bright had not been one of them.

Because Don wasn't on the roster when William made his shortlist.

And now?

Now here he was. Center stage. Usurping the spotlight with all the indifference of someone correcting a clerical error.

William looked at him like he was a thief.

Don met that look with all the enthusiasm of someone glancing at a grocery list. No tension. No rivalry. Just mild interest wrapped in boredom.

The internet, of course, didn't see it that way.

Charles had made sure of that.

With the city half-locked down and schools running skeleton crews, everyone was home. Everyone was bored.

And Charles, ever the opportunist, had spun that into a marketing campaign so greasy it could slide off the screen.

Headlines littered every feed.

[Can William Barns CRUSH the Evil Don Bright?!]

[Villain or Visionary? Watch Don's Redemption Arc Begin… or Explode.]

[Santos Showdown: The Monster vs. The Miracle Kid.]

The numbers didn't lie.

By the time the match began, viewership was pushing five million.

That was more than most televised regional qualifiers got in a full week. The chat systems were melting down.

Even with restrictions in place—one message every thirty seconds, twenty people per group—the chaos was barely contained.

Chat logs blinked wildly across screens around the country:

Bright Residence, Living Room

Amanda grinned like a shark with new teeth.

She sat cross-legged on the couch, remote in hand, volume cranked just below the point of complaint. The massive screen lit her face in flickers of red and silver—Don and William frozen in pre-fight postures.

Samantha stood nearby, arms crossed, expression sour.

"I don't like this," she muttered, her voice low but sharp.

Amanda didn't glance away. "Trust me, sis."

Samantha shifted her weight, one foot tapping against the polished floor.

"That's what worries me."

Amanda smirked wider. "Relax. It's not murder if it's school-sanctioned."

Samantha didn't respond. She just kept watching, her jaw clenched tighter than her arms.

Miss Claire's Office

The lighting was low—intentional, moody, expensive.

Miss Claire reclined in her leather chair like she was watching a charity auction, one leg folded neatly over the other. A glass of red wine spun lazily between her fingers, the light catching the swirl like a performance.

Sylvia perched against the armrest, eyes bright with a kind of childish excitement that matched the glint in her earrings.

"Don's going to win, right, mom?"

Miss Claire didn't answer immediately.

Instead, she sipped once, slow and thoughtful. Then she looked over, smile curling at the edges of her lips.

"Do be a dear," she said, "and hand me my bag."

Sylvia blinked, then scampered off the armrest toward the desk without a word.

Claire's eyes lingered on the screen a moment longer. "It's time we started recalibrating expectations."

Xiao Suite – Infinity Pool

The sun was obnoxiously perfect.

So was the pool.

Women in designer swimwear draped themselves along the edge like decor at a billionaire's funeral. They laughed at nothing, clinked glasses at nothing, and smiled at a man who wasn't looking at them.

Mr. Xiao floated at the center of the pool—arms out, eyes closed, expression unreadable.

One of the women, tan and tailored, leaned forward with a voice that belonged on a perfume commercial.

"Mr. Xiao, you have a call!"

He sighed.

Then he sank—completely—before emerging at the edge of the pool with the kind of smooth grace that made lesser men jealous.

His hand reached up for the phone before his eyes even opened.

The women giggled. One of them ran her fingers across his chest like she'd found treasure.

He answered with a single breath. "I told you not to interrupt me today, Silus."

Silence. Listening. His eyes finally opened.

A slow smile then crept across his face.

"Well," he said, voice slick as the pool surface, "isn't that interesting."

He stood up, water cascading off him like peeled silk.

"Meet me out front in ten."

He hung up. No goodbye.

Turning to the crowd, he offered the faintest incline of his head.

"Apologies, ladies. Business calls."

They pouted. They cooed. They didn't matter.

He was already walking away.
