"OMG - This World is like Totally Turning into a Nightmare!"

"Like - why do I feel so much more powerful,  and like, almost totally fearless with this sword!?"

Alexis excitedly asked Natsuki - just before Alexis surged forward in a continues spinning slash that resulted in a flurry of ashes and blood! Meanwhile, Natsuki launched into a backflip and threw her arms out in a controlled motion - turning ten more undead into a blast of ashes and blood herself!

"I don't know, Blade-chan, but I feel the same way! I feel like I should,d be more afraid, but as seen as I held these nunchaku, my fear disappeared, and I don't even feel tired either!"

Natsuki cheerfully replied, she then looked at Alexis, pointing up at the sky and the buildings all around them! 

"Look, Blade-chan!"

Natsuki shouted with a bit more alarm in her voice, as Alexis looked upwards after skewering five more undead amidst a splash of ashes and blood!

"Like, the sky is changing! It's becoming blood red and black, and the buildings too! Like OMG, this is totally nightmare fuel!"

Alexis replied with awe and a smidge of terror - though she knew not nearly as much if she wasn't wielding the enchanted sword! All around them, the buildings had red and black organic growth on them, as if being consumed by webbing mixed with veins, while the sky was turning into an oily red and black coloration! As Alexis and Natsuki quickly looked around further, it seemed that only their school remained unaffected - shining in magical light that defied the supernatural hellscape around them! 

"What are we going to do, Blade-chan!?"

Natsuki asked as she jumped and scissor-kicked through the heads of two more undead, before slamming her respective nunchaku into a fiercer two, resulting two rapidly successive blasts of ashes and blood! 

"We have to like - find out how and why this happened! And OMG, wait - where's Kaylee!?"

Alexis responded with vigor as she dropped into a splits and spun her torso around as she slashed five more undead in half as a shower of ashes and blood was unleashed around her! Then, a voice appeared that caught the immediate attention of Alexis and Natsuki!

"She's right here - but it's not going to matter since her body and her soul are mine now!"

The possessed Kaylee announced with a demonic, female edge in her voice as the undead made way for her as she stepped forward with her arms outstretched, using her dark powers to gather the blood that was splattered all around into small, sharp, blades of blood that hovered in front of her and pointed at Alexis and Natsuki!

"OMG Kaylee! Like, what happened to you!? And why is your voice like, totally demonic!?"

Alexis yelled, the strength that the enchanted sword had given her clashing with the adrenaline-fueled desperation and familial love for her sister! Despite her natural feelings, Alexis still stood with her sword pointed at head-level, while Natsuki stood ready as well.

"There is no essence or soul of Kaylee inside this body anymore, only Queen Kiku the Vile! Now -  join the unholy ranks of the undead!"

The possessed Kaylee screamed, before unleashing the torrent of blood blades at Alexis and Natsuki - as Alexis retaliated with a fierce spinning slash that combined the power of her enchanted sword with another circular blast of white energy! Alexis' counterattack vaporized the blood blades as the possessed Kaylee smiled with her slit mouth and razor sharp teeth.

"You'll never win unless you kill me - and my near-endless hordes of the undead will ensure that you join them!"

The possessed Kaylee yelled as she disappeared in a flash of black and red energy while the undead closed in on Alexis and Natsuki as they both stood at the ready with their enchanted weapons!
