Chapter 19: Idol Training Camp (a.k.a. Raiko's Trial by Glitter)
The boyband training facility—more fortress than school—loomed over Raiko and Noona like the last boss of capitalism.
"This place smells like debt," Raiko muttered.
Inside, the halls echoed with synchronized footsteps, peppy vocal scales, and the occasional scream muffled by dance mats. The manager, a man with glasses and the aura of a war general, handed Raiko his uniform: tight pants, pastel shirt, and glitter gel.
Raiko stared. "Is this armor... cursed?"
"No. It's sequined."
Thus began the training days.

Day 1: Dance Practice
Hyun-bin scoffed. "He moves like a golem that got stuck halfway transforming."
"Shut it, glitter goblin," Raiko grunted, stepping awkwardly.
Minjun tried to help. "Just follow the rhythm and pretend your spine exists."
Raiko had no natural groove, but his headbanging instincts gave him a strange sharpness. Every time the beat dropped, he added a dramatic stomp and eyebrow twitch. The choreographer clutched her heart.
"He's terrible… but I can't look away."

Day 2: Idol Persona Training
Raiko was forced into a mirror-filled room.
The trainer clapped. "Time to pick your idol persona! Are you the cool one? The sexy one? The sunshine? The mysterious wolf?"
Raiko blinked. "I'm the blood god of distortion."
Trainer: "Okay! So… mysterious wolf with anger issues it is!"
He was handed a list of required poses. One included finger hearts.
> "What is this hand spell?"
> "It's not a spell. It's love."
> "LIES."
Meanwhile, Eun peeked in and whispered, "Hyung, I'll teach you finger hearts later."

Day 3: Vocal Drills
"Less screaming, more belting!" barked the vocal coach.
But when he focused—when he truly sang—his voice transformed.
Grit layered over control. Raw power laced with emotion. A voice that could both serenade a widow and ignite a battlefield just like M. Shadow did.
The coach blinked. "That… that's the voice of someone who's fought depression with riffs."
Minjun teared up. "That was... powerful and magical."
The manager scribbled notes: Potential. Dangerous. Must monitor.
No one knew who M. Shadow was. Except Noona, who whispered in awe, "He channeled the sacred flame."

Day 4: Night Routine Chaos
At the dorms, Raiko shared a room with Taeyang and Jinwoo. He insisted on placing garlic near the windows and strumming his guitar like a lullaby.
Taeyang: "Bro, that riff makes me wanna fight God and hug my mom at the same time."
Raiko: "That's the point."
He refused to wear the provided cute pajamas, choosing to sleep shirtless in ripped pants. The other trainees were scandalized.
Minjun: "Why does he look like he just escaped a romance dungeon?"

Day 5: Styling Disaster
Noona was given temporary access to the styling room. With Yu-Riella's help, they bullied Raiko into a new look—still edgy, but manageable.
Raiko's dark hair was tied into a sleek low ponytail, his brows shaped just enough to look mysterious, and his eyeliner was reduced to human levels.
The makeup artist whispered, "He's like... bad boy prince meets that brooding elf from a romance novel."
Noona handed him a mirror. "Accept this compromise. Or accept celibacy."
Raiko nodded gravely.

Day 6: Cooking Break
During one lunch break, Raiko volunteered to "cook something metal."
He made bone stew. Literally. There were bones. And one suspicious frog leg.
Noona walked in, saw the table, turned around, and walked back out without a word.
Yu-Riella (visiting that day) whispered, "I'm calling the priest."

Mini-Scene: Noona & Manager
Noona sat down with the manager privately.
Manager: "He's… raw."
Noona: "He's fire. Just needs a flameproof stage."
Manager: "He nearly headbutted the LED wall."
Noona: "That means he likes it."
Manager (scribbling in clipboard): "Psychotic but pretty."
---
By the end of training camp, Raiko hadn't lost his metal soul—but it now wore glitter on top.
The manager reviewed their final practice.
"He's unorthodox," he muttered. "But he's marketable."
Noona grinned. "Told you."
The debut stage was next. And the chaos had only just begun.
That night, Raiko stared at himself in the mirror—sparkling skin, stylish ponytail, and lips slightly tinted from lunch.
"…Have I… become a protagonist?"
From the hallway, Noona (without looking up from her tea) said dryly: "You look like a side quest I accidentally fell in love with."
Raiko smirked.
"Metal."

Author Notes:
This entire chapter is a documentary on what happens when you force a metalhead into skincare bootcamp and replace his battle axe with vocal drills.
Noona's patience was tested. Raiko's eyeliner survived. And someone cried over a finger heart. (It was probably me.)
Training arc: complete. Insanity: ongoing.
