I am assuming you know Konosuba already. Also, things are gonna get hot by the end of this.)
1 Hour Later
A large base was established and soldiers, pilots, and tankers were waiting for the signal. Then their radios came to life.
"Attention all units, Operation: Extermination has begun."
They dropped what they're doing and rushed to their respective transport.
Pvt. James was hauling ass to his Blackhawk when his Co stopped him.
"James, did you brought the flash drive?" Asked a Sergeant.
"Hell yeah, I did!" Said James as he pulled it out.
He plugs it in and it starts playing Gimme Shelter by Rolling Stones.
The Helicopter takes off just right as the Beginning of the song blasts out of the speakers.
Oh, a storm is threat'ning
My very life today
If I don't get some shelter
Oh yeah, I'm gonna fade away!
"We're arriving at the first town and play it louder!" Yelled the pilot.
Meanwhile in a town called Axel
Kazuma, Aqua, and Megumin were sitting in the guild when they heard the alarm.
"Alert, every available adventurer must go to the south gate immediately.
"Come on Kazuma we might get some sweet sweet moolah!" Said a blue-haired girl as she picked up her staff.
"Alright let's go Aqua!" Responded Kazuma. "Come on Megumin! Darkness is probably there already!"
"Alright alright."
Erm, idk uh 2 minutes later?
Darkness was standing firm in front of a crowd of adventurers when she saw them.
12 flying Blackhawks flying in formation mixed in with 6 Apaches.
She looked to her left to see Megumin chanting. She looked at the helicopters only to see smoke coming from one of them.
Megumin lifted her staff and chanted something.
"Blah blah blah- EXPLOS-"
Boom!
An Incendiary missile from a Flash M202 missile hits the ground setting the ground ablaze.
"AHHHHHH PUT IT OU-" Screens Megumin as she falls to the ground with burns all over.
(I did say that Megumin is gonna be really really hot.)
Darkness, Kazuma, and Aqua rushed over.
"Megumin are you alright?! Aqua get your spell ready!" Commanded Kazuma.
But as they were about to heal her the Apaches start opening up with the faint sound of music.
War, children.
It's just a shot away
It's just a shot away!
War, children.
It's just a shot away
It's just a shot away!
It shredded the adventures apart as they tried to scramble back into town.
A Blackhawk lands next to them and a soldier approaches them.
"LINE UP AGAINST THE WALL NOW!" Ordered the Soldier.
The group complies and lined up dragging the injured Megumin along with them. Kazuma sensing his demise is imminent, decided to run but his escape was cut short by a bullet to the head. Then they got brutally shot and headed for Axel.
Elsewhere a Blackhawk began clearing their Landing Zone inside the town.
BRRRRRTTT
A gunner on a Blackhawk cuts down a group trying to escape in a carriage and they unload their soldiers and take off.
brrrrtt
An Apache fires its explosive rounds at a carriage killing the occupants inside.
3 Flamethrower operators torched the town ablaze setting it on fire they burned through every house they saw.
The Guild
A missile hits the guild sending debris all over the place. The people there drew their swords and waited patiently for them to kill them. But when they arrived they were burned alive along with the guild. Setting them ablaze and killing them slowly.
After the day was over the town was mostly reduced to rubble. With almost no building standing. The soldiers checked the rubble and killing the survivors then took off to find the next town.
