A/N: Since my Halloween special is still on the works, here is the trailer or prelude for the Choukri island Incident. Do not worry, there's still about twenty-six days left until the Choukri Island is out. Do not worry, I will try my best to write this special fanfiction.

Disclaimer: I do not own Akame ga Kiru and Halo, they belong to their rightful and respectful owners except my OCs.


Unknown UNSC Base

Unknown Forerunner Shield World, Soell System

November 2nd , 2558

It was supposed to be a daily check-up on the UNSC base. Checking up on any damaged done by the wildlife. But, just today one Private Jen Ramstein, long brunette hair, standing about foot ten and more importantly a pilot within the UNSC. She was currently sleeping on her dorm in the early hours of the day, when all of a sudden, there was an alarm.

"Alarm, hostile forces in the hangar bay! Need assistance from any UNSC personnel!"

Now that was strange. She might've guessed that the Covenant Remnants managed to get on board. So, she changed to her combat gear and went towards the hanger bay. She dashed her way through, and saw that the marines were firing at something.

"Contact!" one of the marines shouted.

"Just what the hell are these things?!" another marine shouted.

"What's going on?!" Ramstein shouted and soon got her answers.

She soon saw a lot of squid-like creatures coming towards her position, so she shot them with her Battle Rifle. What she saw next was something that would horrify her. It was a marine, with tentacles sticking out of its chest, a whip on its left arm and more importantly, it was shooting her.

Luckily, she managed to kill the marine and retreated into a safe distance. She ran as fast as she can before a familiar voice stopped her.

"Ramstein!" she saw her Sergeant with his shotgun.

"Sir!" she saluted.

"Not now, Ramstein!" He shouted, making her flinch.

"Do you know what those things are, sir?" Ramstein asked as she was still recovering from seeing the zombie-like marines.

"I don't know, but you and I need to retreat into the hanger bay!" he ordered.

"Are so sure we should go there? I mean-" she was bout to say but was interrupted by a loud explosion.

The two turned around to see more of those creatures and more marines that Ramstein gunned down. There seems to be more and more of them. The Private began to trembling as she had never been so scared in her life before.

"Listen!" she looked back at her Sergeant. "You need to get out of here and send a distress signal to any UNSC personnel and tell them to send more reinforcements!"

"Got it!" She soon dashed her way into the hanger bay where there was a pelican. She looked pass her Sergeant and saw more of those squid like creatures. This started to make her shake, but that didn't matter. She soon boarded the Pelican and started it, where she saw her Sergeant shooting at those creatures, unfortunately, one of the creatures latched onto his neck and saw that the creature had token over his body and it was the same as the one that she killed.

Tears started to come to her eyes, but that didn't stop her piloting the Pelican and soon left. She at the passenger seats, where she saw none of those creatures from that planet. How is she going to explain it to the nearest UNSC Vessel if she has no evidence?

Somewhere underground, the newly infected were putting a lot of bodies into some sort of biomass. It took them for a while before it started to speak again.

"Ahhhh. Thank you." The voice in all of their heads spoke. "At last, I am reborn and now it is our time to enact vengeance."

Many of the infection forms screamed in joy at this announcement and soon all of them left. Except for one, who the voice wanted to talk to.

"I have a special task for you." The voice said inside of the infected human's head. " Go to Choukri Island, which belong to an Empire filled with Greed and corruption and Evil. This will be our perfect feeding ground. But, in case if that fails, my agent will be there to replace you."

The infected saw a spider-like creature and soon saw its transformation. The voice was happy about its plan and will know that it will backfire. But that didn't matter now. The vengeance was already set in motion.

Days had passed and there was a Pelican ready for the infected to board and it soon was hovering. The voice then opened a portal where it will be orbiting near the planet's orbit. The pelican soon enters the portal and soon begins its mission.

To make a new feeding ground for them.
