Chapter 20: The Debut Disaster

(a.k.a. "Who Approved the Name LUMINO5?")

The air backstage was thick with nerves, hairspray, and denial.

"Alright boys, we're one minute from debut!" barked the assistant stage manager, clipboard trembling like a scared rabbit.

"You all look perfect."

"Just… don't improvise."

"Especially you, Raiko."

Raiko stood stiffly at the back, dressed in glittery white, his freshly styled hair defying gravity—and dignity.

His guitar was boxed in decorative ribbon, his amp muted and charmed.

It was a crime scene.

He looked down at his heels.

> "This is a hate crime against metal," he muttered.

Noona, hiding behind a curtain with Yu-Riella and her son (who wore a hand-painted shirt that read: NOONA 4 LIFE), glared through her binoculars.

> "If he growls, he sleeps on the roof."

The other members were pumped.

Hyun-bin struck five poses per second.

Minjun whispered sweet lyrics to a mirror.

Taeyang beatboxed into his armpit.

Jinwoo scrolled through live analytics.

Eun clutched his bunny like a war charm.

A huge shimmering sigil floated above the stage as the lights dimmed.

The announcer's voice boomed:

> "Presenting the realm's newest idol sensation… LUMINO5!!"

Raiko's eyes twitched.

> "There's six of us," he hissed.

Hyun-bin: "Shhh! The five stands for our harmony!"

Raiko: "That doesn't make—"

Too late. The music started.

The first verse went smoothly.

Clean vocals.

Sharp moves.

Dead smiles.

Sparkle overload.

Even Raiko, through sheer willpower (and the memory of Noona's threats), danced as trained.

It was clean.

It was controlled.

It was painfully boring.

Then came Raiko's line.

A soft falsetto solo.

He stared at the crowd—glitter banners, screaming fangirls, enchanted glowsticks.

The spotlight hit him like divine judgment.

His ribcage guitar itch clawed at his soul.

The muted amp behind him seemed to whisper *"Coward."*

Time slowed.

The crowd's expectant faces.

His bandmates' synchronized breathing.

Noona's binoculars glinting like sniper scopes in the wings.

He felt the weight of every compromise, every glittery outfit, every dance step that made his metalhead ancestors weep.

The falsetto line hung in the air, waiting to be born.

Raiko raised the mic.

And chose violence.

> **"YEAH!!"**

The word didn't just leave his mouth—it *erupted* from his soul like a volcano that had been dormant for millennia.

James Hetfield fury crossed with M. Shadows darkness, seasoned with his own brand of beautiful destruction.

---

But that was just the beginning.

He grabbed his decorative, ribbon-wrapped guitar and *yanked*.

The pretty bow exploded into sparkles.

"His fingers gripped the strings—still resonating with the weight of the drop D tuning, the distortion hums beneath his touch, but his presence? It shreds the air with raw power."

He didn't sing his line.

He **conquered** it.

The gentle falsetto became a raspy war-cry that sounded like velvet being shredded by lightning during an earthquake.

His voice climbed and dove, growled and soared, turning a simple love ballad into an anthem for the beautifully damned.

He didn't dance.

He *prowled*.

Each step was deliberate, predatory, like a panther in sparkles who'd finally remembered he had claws.

When he slashed the air with his arms, actual *sparks* flew—whether from magic or pure metal energy, nobody knew.

The stage lights flickered.

The enchanted glowsticks in the audience started changing colors without permission.

And when the chorus dropped, he didn't just point to the audience—he threw his whole body into it, one arm extended like he was summoning thunder, the other clutching the mic like a weapon of mass seduction.

His voice hit notes that shouldn't exist.

Low enough to wake dragons, high enough to make angels weep, rough enough to sandpaper hearts smooth.

--The Chaos Amplified---

The magical sound system, designed for sweet boy band harmonies, started *smoking*.

Crystal speakers cracked.

The backup dancers' choreography spells malfunctioned, leaving them frozen mid-twirl.

Backstage:

- The manager didn't just faint—he *ascended* to unconsciousness

- Three lighting technicians started a support group

- Someone's familiar (a crystal hummingbird) began headbanging

- The wardrobe assistant whispered "This is what peak performance looks like" while clutching sequins

The other members froze.

-Hyun-bin attempted emergency twirls.

-Minjun looked like he was about to cry.

-Taeyang started headbanging mid-spin.

-Eun squeaked.

-Jinwoo's enchanted scroll caught fire.

Noona watched in horror, somewhere between a proud parent and a woman watching her boyfriend burn down a wedding.

> "I hate how good he looks right now," she whispered.

"I hate that it's working."

---The Crescendo---

For his final note, Raiko did something no boy band member in history had ever attempted:

He *belted* while *growling* while *maintaining perfect pitch* while looking like sin incarnate in glittery white.

The note held.

And held.

And held.

Windows in nearby buildings cracked.

Dragons in distant mountains lifted their heads.

The realm's ancient metal gods whispered: *"Finally."*

When he finally released the note, he threw his head back, arms spread wide like he was embracing chaos itself.

Silence.

Then the world exploded.

---The Aftermath---

The crowd didn't just applaud—they had a *religious experience*.

> "THAT'S NOT SINGING, THAT'S SUMMONING!"

> "HE JUST TURNED A LOVE SONG INTO A BATTLE HYMN!"

> "I NEED HIM TO YELL AT ME IN SEVEN LANGUAGES!"

> "FORGET BIAS—HE'S MY ENTIRE PERSONALITY NOW!"

One fan whispered, "That's not a voice… that's a dragon breakdancing."

Magical social media exploded mid-performance:

#BadBoyPopPrince

#VocalChaosKing

#AngryPrince

#YellAtMeOppa

#ChaosStageDebut

#LUMINO5NeedsTherapy

And somewhere in the audience, a music critic fainted while scribbling: "This is what happens when pop meets anger meets divine intervention meets pure, concentrated audacity."

Noona clutched Yu-Riella's son.

> "...I'll never hear the end of this."

Yu-Riella sipped her tea. "At least now you can sell merch."

Onstage, Raiko smirked as Taeyang threw himself into a squat-mosh.

Hyun-bin twirled aggressively.

Jinwoo tossed confetti like a hex.

Minjun hugged Eun and screamed, "We're doomed—but it's BEAUTIFUL!"

And thus began the chaos.

The boyband had debuted…

As LUMINO5.

And the world would never recover.

Author Notes:

I didn't mean for Raiko to hijack the stage. He did that himself. Now he's trending in three kingdoms, two cults, and one questionable fanfic forum.

This boyband was supposed to be polished. Instead, it got possessed by thunder and eyeliner. And no, I don't know why they're called LUMINO5 either. Please stop asking.
