CHAPTER 10: The Metal Messiah in Chains

Scene: Yu-Riella’s Chaotic Yet Cozy Home

Glittery slime boils on the stove (for skincare, allegedly).

A toddler (Yu-Riella's son) rides a chicken.

Yu-Riella files her nails with a gemstone-encrusted dagger.

Disaster Mustache (her husband) practices fake kung-fu stances in slow motion near the laundry rack.

Suddenly—

Yu-Riella (reading aloud from gossip flyer):

> “Black Noise Cultist Captured After Tavern Incident—Public Screaming Causes Panic, One Baby Temporarily Floated… huh.”

Noona (from the table, sipping tea):

> “…Black noise?”

Yu-Riella (giggling):

> “Yeah! Some crazy street man with cursed hair and a weird haunted instrument started howling demon sounds in a bar! They say it was so powerful it summoned an imp—who got sat on immediately, poor thing.”

Noona freezes mid-sip. She lowers the cup with mechanical precision.

---

The Suspicion Awakens

Noona (carefully):

> “What did this… madman look like?”

Yu-Riella (snorting):

> “Weird black armor. Long hair. Looked like he hadn’t slept in years. Screamed something about ‘unheard gods’ and ‘the riff of awakening’? Honestly sounded like a broken music box possessed by a gremlin.”

Pause. Noona closes her eyes for one long second.

A deep breath. The air chills by five degrees.

Then—

Noona (soft, flat, and full of restrained rage):

> “…That idiot.”

---

The Tsundere Awakens

She stands. Not fast. Not loud. But with terrifying calm.

The toddler stops riding the chicken and bursts into tears.

Disaster Mustache drops his stance and hides behind a laundry sheet.

Even the chicken plays dead.

Yu-Riella blinks.

> “Wait… you know him?”

Noona doesn’t answer right away. She looks down. Touches her teacup. Her voice softens for a heartbeat.

Then she looks up—eyes big, gentle, and tragically sincere.

She bites her lip. Frowns a little. Then—

Noona (quietly, like it hurt to admit):

> “…Can we go get him back?”

Yu-Riella stares. Her brain short-circuits.

> “W-Wait what—why are you making that face?! I-It’s too much! I can’t resist puppy eyes!! I’ll help! I SWEAR I’LL HELP! JUST DON’T LOOK LIKE THAT, I’M WEAK TO CUTE!”

The toddler sobs harder.

> “Save Uncle Screamer!! Waaaaaah!!”

Disaster Mustache (bowing instantly):

> “My chi trembles in your presence… also I think my mustache just curled backward from the emotion.”

Nightfall – Operation: “Bail the Idiot Out”

Later—

Yu-Riella dons her “Legal Weasel” cloak (used for shady contracts and bribery).

She’s carrying scrolls, pouches, and a forged license or three.

Noona walks beside her in a dark hood. Graceful. Calm. Silent.

But underneath… she’s ten seconds away from dragging someone home by the hair and giving them soup. Violently.

Yu-Riella (whispering nervously):

> “Listen, don’t go too hard on him when we find him. He probably didn’t mean to scream open a portal to musical hell—”

Noona (deadpan):

> “I gave him one rule. One. Don’t become a public hazard.”

Scene: Prison – “Black Noise Containment Wing”

Two guards at the barred door. Shaken.

Guard 1:

> “He’s been… humming.”

Guard 2:

> “Tried to remove the instrument. It’s… attached. Or cursed. Or singing back. One guy touched the box and now he won’t stop whispering about strange notes and things.”

From the cell:

A faint hum. Then a warped dun-dun-duuuuun~ echoing like a drunk banshee tuning itself.

Guard 1 (shivering):

> “Whatever he’s doing… it’s not music.”

---

Inside the Cell

Raiko. Scratched. Covered in egg bits. Smug.

The cursed amp pulses beside him.

His guitar—still fused to it with rope and a haunted shoelace—sits across his lap like a chained beast.

He mutters:

> “Can’t believe they called it ‘black noise’... Philistines. That was art.”

He smirks. Hums a riff. The amp growls.
