Bit of a doozy, eh? One thing I should explain is how easy to have cut Jaune's head off. Getting around aura, let's say demonic possession saps it to the red. As for how someone was able to cut through the spine in one cut, Jaune was pretty much spineless anyway. I couldn't resist that joke, I'm sorry.
I was a bit disappointed by the first chapter, felt like it ended a bit too early and went too quickly into the action. I'll do my best to try and rectify that in later chapters, if you have any critiques go right ahead.
One last thing, religion... Something that is only barely touched on, but I try to make due with what I'm given.
- Menagerie seems to have a polytheistic or possibly henotheistic tradition, thus expect her to say "gods" in place of Oh my god.
- Patch appears to have some level of monotheistic tradition, with Yang saying "oh my god" in canon.
- Atlas and Mistral are a bit more of a guess who so might see some variety with JNPR and Schnee.
The group were still shellshocked at what transpired, Pyrrha Nikos murdered Jaune Arc in cold blood. Well, not cold blood as his was like wearing a warm sweater made of molasses. A warm sweater that a significant amount of the group had on.
The murderer was currently in fetal position, rocking back and forth as she kept muttering I..I'm sorry... Ren was using his semblance to keep him and Nora from going into the same catatonic state. RWBY on the other hand, they were a little more unhinged...
They were the ones to wrap Jaune's body into a burial shroud, which was really just a white bedsheet. Weiss' usually pristine dress was a dark copper, constantly trying to scrub out the blood to no avail. Ruby was hyperventilating, crying into Yang's shoulder who just kept staring at the shroud. Blake, Blake was strangely calm but screaming on the inside.
"P..pyrrha...?" Ren put his hand on her shoulder, her breathing hitched. "M..maybe you should wash up.. a..all of us should.." She nodded, slowly getting up and walking to the bathroom. With each step, the carpet got a new red stain.
Blake coughed into her hand, "S..so... who wants to dig the hole...?"
I..It's all my fault... It's all my fault...
She was essentially back into the same position, only this time less blood. The champion laid back in the tub and covered her eyes, Jaune's visage the only thing she can see.
Back in the funeral parlor, strange happenings have started.
"HE JUST FUCKING MOVED!"
Ruby clutched onto her sister, shaking even more as she swore to God that his finger twitched. Blake sighed, not looking at the corpse at all. "It.. it was most likely just the nerves dying t- OH FUCKING GODS!"
Everyone's attention turned to see the shroud was empty, Jaune's body nowhere to be found.
"This isn't happening.. this isn't happening.. this isn't happening.." the Schnee looked like she was about to tear her hair out.
Nikos finally managed to calm down somewhat, crying out to the point where her eyes were red and puffy. She laid back, staring into the ceiling as she thought about what the next days will bring. I.. I have to tell his family.. I.. I have to turn myself in.. I need to turn myself in..
"Why'd you do it, Pyrrha?"
"Not now, J-"
She froze, looking past her knees to see the blonde's severed head floating in the water. His eyes were staring at her but not with anger or want of vengeance, but with betrayal. He appeared to be on the verge of tears as he continued. "W..was I a bad leader.. Was that why?"
"J-n-"
She couldn't say a word, needing a minute to take this all in. After a deep breath, she went to grab the head, "You're not real..."
Her fingers touched soft, fluffy hair and her mind shattered. The tears came back as she clutched the head, begging for forgiveness.
"It's okay, Pyrrha, I forgive you." He smiled, kissing her cheek. She sniffled, raising him so she could see his eyes. "R-really?"
He nodded (well as well as one can nod with just a head), "But can you forgive me?"
"F-for what, Jaune?"
His eyes rolled into the back of his head, his veins becoming ridges that ran along his once pristine face, and his mouth was now a maw of fangs. The demon bit her wrist as hard as it could, piercing through the skin with ease. Pyrrha screamed at the top of her lungs, only to feel a pair of hands grab her by the hair and dunk her into the water. She looked up and saw the headless corpse of Jaune holding her down.
She smashed the head into the porcelain tub, the shower rod wrapping itself around the cadaver. The champion ran out of the bathroom as fast as she could, collapsing into the living room.
"P-Dear gods why are you naked?!"
Whatever she was about to say was interrupted, as the group's attention were now drawn to a pair of footsteps. Everyone's jaw dropped as they saw Jaune, nary a scratch on him and his head reattached, walk into the living room. "H-hey, guys."
Pyrrha backed up, pointing at him like he was some monster. "G-get away you.. you.. YOU FUCKING DEMON!"
She was about to call upon her semblance again, until Nora sped to give Jaune a hug. "N-nore, stay away from it!"
"Fearless leader! Oh thank God I don't k-" Her words were cut short, the corpse revealing its true nature as it tackled her. It bared its fangs like a common Beowolf, trying to bite into her neck as it snarled. Ren immediately pulled out his weapons, aiming them at Jaune.
That's not him, that's not him... He repeated as he unloaded into the monster, riddling it with holes. The Mistrali let out a sigh, hoping that this would be the end of the nightmare. The corpse standing back up as if it were nothing dashed those hopes. It lunged at the boy only to be cut short by Ruby stepping in, bisecting the abomination.
It writhed on the floor in pain, crawling towards Ruby. "I'll swallow your soul! I'll swal-" A scythe to the finally shut it up. Once it appeared that the corpse was finally acting like a normal corpse. Ruby did the only thing that she could after seeing her precious baby covered in yellow ichor and blood.
"AAAAAAAAAAAAH!"
After tossing the remains into the cellar and getting Pyrrha something to wear, the group huddled once more in the living room. "T...WHAT WAS THAT?!"
Weiss screamed at the top of her lungs, even Blake was shaken. Of all the things they've heard, from Jacques Schnee having a secret faunus lovechild to Ozpin being an immortal wraith, they could never comprehend what transpired. Dead bodies don't move, dead bodies don't teleport, dead bodies don't grow teeth and fucking claws.
The remnants of Team JNPR were still shaken, holding onto Ren for comfort as his semblance was put through the ringer. Team RWBY on the other hand were thinking of what should be done now. "We need to call Uncle Qrow.. Ozpin.. fucking anyone..." Yang muttered, going for her scroll.
The device only showed a static screen, everyone else checked their's and got the same results.
Meanwhile, a couple hundred miles east of the cabin Qrow Branwen was where he thought he sent his nieces. It was a modest little house a grateful noble gave him in exchange for saving his life, little did said nobleman know is that Branwen was also sleeping with his wife at the time. He chuckled at the memory, sipping from his flask as he walked in.
"Ruby? Yang? Favorite uncle is here!"
He raised an eyebrow, place look untouched and there was no response. The veteran hunter checked everywhere he could, even calling for their friends.
"Icemidget?! Tai's bastard son?!" Still no response, causing the man to growl and start racking his brain to figure out where he sent them. In hindsight, he probs should have been sober when giving them the location details but he was sure they were in the area. Really, the only other place they could be that he knew about was Old Man Nobi's Ca-
His eyes widened, once steady (for a drunk's) hands started to shake and he collapsed into the nearest seat. Memories long since repressed came back of his days with STRQ, the horrors uncovered at that cabin, the monstrosities that he tried so hard to keep buried that he filled a room with cement personally.
Those memories changed as he began to imagine Yang and Ruby in place of him and his sister, his breathing hitched as he immediately grabbed his scroll and tried calling them.
The man ran outside as there was no answer, beginning to call someone else.
"Tai... I fucked up!"
Shorter than I would've liked, let me know if you guys would prefer longer chapters like the one prior or something more akin to this. As for the events of this chapter, I'll do my best to answer any questions you guys have next time. Hope you enjoyed or at least were entertained.
