The night was supposed to be chill.
Hana had promised herself—no more insane missions, no more secret battles, no more surprise boss fights.
Just a peaceful evening at the Black Dragon Underground Auction House.
You know… where normal people bid on priceless art, vintage cars, or mysterious ancient artifacts under fake names.
Simple.
Harmless.
Calm.
Yeah, right.
Discovery of the Chaos Caravan
The auctioneer, a portly man with a pencil mustache, tapped his gavel three times.
"Next up — Lot 88: An unknown schematic from a closed syndicate vault. Starting bid, ten thousand won."
The screen behind him flickered.
An old, yellowed blueprint popped up — crinkled edges, stained like someone had used it as a coffee coaster.
Drawn across it: a ridiculous-looking wagon with flaming wheels, cartoonish explosions, and the words:
"Chaos Caravan: Official Entry Pass."
"Huh," Minjae muttered, studying it through his binoculars from the VIP booth. "Looks like a meme.""
"It's junk," Yuri declared, stuffing popcorn in her mouth. "Ten thousand won? Not even worth a used textbook.""
Hana's aunts, however, turned pale.
Aunt Kim nearly dropped her churro.
Aunt Park gasped so loudly three auction guards turned toward them.
"Minjae, NO," Aunt Park hissed. "Don't even think about it.""
"Why not?" Minjae blinked. "It's just a blueprint. I'll win it for laughs.""
Before anyone could stop him, he raised his auction paddle.
GONG!
The auctioneer beamed. "SOLD! To the charming young man in Booth 7!""
"Bro," Yuri said flatly. "You just doomed us all.""
In the car ride home, the aunts sat in ominous silence.
Hana tapped the rolled-up blueprint against her palm. "What's the Chaos Caravan, anyway?""
Aunt Kim squeezed her temple like a migraine was brewing. "Only the most insane, illegal, city-wide underground race in mafia history.""
Aunt Park clutched her seatbelt like it was a lifeline. "A death race. No rules. Winner claims the Vault Key of their family legacy.""
"Wait, wait, wait—" Hana sat up. "Are you telling me there's an actual Mafia Vault somewhere?""
"Yes," Aunt Kim said darkly. "And it's filled with treasures, secrets, and debts so old even WE don't know them.""
Hana's eyes gleamed.
Minjae's slow grin matched hers.
"We're entering," Hana declared.
Yuri coughed on her soda. "ARE YOU ON SUGAR WITHDRAWAL?!""
But the decision was made.
The Chaos Caravan awaited.
Building the Battle Wagons
The abandoned warehouse on the outskirts of Seoul buzzed with activity.
"Alright, team," Hana clapped her hands. "Here's the plan: We build, we race, we WIN.""
The rules were clear:
Create your own "chaos cart" from scratch. It had to survive explosions, sabotage, and spontaneous musical numbers. Style points? Mandatory.
Hana's ride:
She picked her grandfather's dusty old mafia parade car — a black beast with dragon decals and gold-plated mirrors.
"We'll armor it like a tank and soup it up with nitrous," she said, grinning.
The aunts cheered.
Minjae's ride:
A sleek, silver ex-courier drone wagon, low to the ground, rigged for insane speeds and equipped with hacking modules.
"I'm calling it: Ghostrunner," Minjae said.
Yuri's ride:
A moped.
With duct-taped rocket thrusters.
"Don't question genius," she shrugged.
The aunts' ride:
A beat-up food truck…
Transformed into an armored pastry cannon launcher.
The montage was glorious:
Hana welding plates onto her dragon car, sparks flying everywhere. Minjae hacking GPS systems while sipping cold brew. Yuri setting a scooter on fire accidentally (then calling it "field testing"). The aunts baking pies with "surprise payloads" inside.
At sunset, they stood in front of their monstrosities.
Hana wiped a smudge of grease from her cheek. "We are officially insane.""
"Insanely AWESOME," Yuri corrected.
Entering the Race
The starting line was a massive junkyard, lit by floodlights and surrounded by screaming crowds.
Hundreds of battle-wagons rumbled to life.
Some were Mad-Max styled dune buggies.
Others were literal carnival floats with secret machine guns.
Their competition included:
A ninja courier team on hoverboards. A biker gang of grandmas with turbocharged tricycles. A group of businessmen wearing full tuxedos... and piloting a literal teacup ride.
A masked official stepped forward with a megaphone.
"RULES OF THE CHAOS CARAVAN:
No rules. First team across the finish line wins. Sabotage encouraged. Sabotage expected. Last team standing gets style points."
He blew a whistle.
VROOOOOOM!!!
The race began.
With a final whistle, the race began.
The Race and Sabotage
The first obstacle came almost immediately—a giant pit of quicksand that stretched across the track.
Hana grinned. She slammed the gas pedal, sending her parade car roaring forward. The wheels spun, kicking up dust, but she expertly swerved around the edge of the quicksand, narrowly avoiding it.
Minjae was already in the air, his drone weaving through the air at breakneck speed, dodging incoming fire from a rival team's missile launcher. He hacked into their system mid-flight, causing their weapons to malfunction and explode.
"Nice work," Hana called out as they tore through the chaos.
Meanwhile, Yuri had somehow transformed her scooter into a rocket-propelled machine, leaving behind a trail of sparks and flames as she zoomed past the competition. She jumped a ramp and crashed into a massive food truck, knocking it off course and into a pile of hay bales.
The crowd cheered.
And the race raged on.
Final Showdown and Winning the Vault Key
As they neared the finish line, only two teams remained: Hana's crew and a rival mafia family known for their ruthless tactics. The final stretch was a series of ramps, jumps, and tight corners, with obstacles ranging from flaming hoops to sudden pits of oil.
Hana's car was in the lead, but the rival family's vehicle—a sleek, armored van—was hot on their tail. The driver, a grizzled man with a scar across his face, gunned the engine, aiming to ram them off course.
Minjae's drone swooped in, hacking into the rival team's van and causing their weapons system to backfire. The van exploded in a fiery burst, but the team didn't stop.
At the final ramp, Hana made a daring move—she slammed the car into a 180-degree spin, sending it flying through the air, directly toward the enemy's lead driver. She landed on his vehicle, grabbed the golden key hanging from his neck, and yanked it free just as they both slammed into a giant inflatable obstacle.
She landed in a pile of fruit crates, holding the golden key triumphantly.
"We did it!" Yuri yelled, laughing.
The crowd went wild. The rival mafia team was still recovering from their explosion, and Hana's team crossed the finish line with the key.
End of the Chaos Caravan
As they made their way back to the warehouse, holding the Vault Key, Hana looked at her team.
"Well, that was insane," Minjae said, wiping sweat from his forehead.
Yuri was still laughing, her scooter in pieces behind her. "I can't believe we survived. This was the best!"
Aunt Kim and Aunt Park were waiting at the door of the warehouse.
"That was... reckless," Aunt Kim muttered.
"But you're not dead, so... I'll call it a win," Aunt Park said, giving them a thumbs up.
Hana smirked, holding up the golden key. "Mission accomplished. And now, we've got a treasure to unlock."
The team cheered, and for a moment, they felt invincible. The Chaos Caravan had been conquered. And with it, they'd gained access to a legacy far older—and far more dangerous—than anything they'd ever imagined.
