Summary
"Come on Celine! It'll be fun, I promise!" Zoey exclaimed, pulling her too tall mentor along.
Celine stammered, trying to find an excuse. She glanced to her right, noticing what Zoey was doing.
A livestream.
Fuck.
My favorite fics involved either fluff, putting Rumi through a MEAT GRINDER, or unhinged shit. Or Celine having a bad time but not being a bad parent. Or my AUs of Kpop demon hunters.
This is unhinged shit mixed with two of my AUs from tumblr, an AU where Celine is a reincarnated fan from our world and an AU where Celine has the power to mimic demons because of the Honmoon.
(Or— a fic where someone reincarnated as Celine, gets stressed tf out, and is trying her best to not do very bad shit and break out of character.)

Summary
"Are they still chasing us!?" Rumi yelled, running as fast as she could with Celine.
Celine glanced behind them. "I don't see them chasing us, can you look at the rooftops?"
"Huh?" Rumi breathed as she ran. "Uh, yeah, sur— OH MY GOD THEY'RE ON THE ROOFTOPS?!?!?!"
"Variations of the Sunlight Sisters are unpredictable, Rumi! Listen to their sounds while I find a distraction!"
"ONE THEM HAS A BATTLEAXE!?!??!"
Celine, from a world where she's the last Sunlight Sister and occassionally gets summoned into different timelines to help others, and Rumi, from a different timeline than hers and stuck in a timeloop.
Both get stuck in the past and are desperately trying to figure out how to get back to their respective timelines before they're found, trying to use the skills they developed during the timeloops they were bored in.
(First chapter is prologue)

Summary
"Wait..." Mira muttered, her eyes narrowed as she stared at the pictures.
"What is it? What did you find?" Zoey asked, peering over Mira's shoulder before she froze.
The picture was old, taken by paparazzi when Rumi was still young. It was deemed edited by the public, and people were angry at the company and paparazzi that took the picture.
But it showed Celine snarling at the camera as she shielded a nervous toddler Rumi behind her, clutching Celine's leg sleeve.
But what was evident were the claws that Celine had, along with her sharp teeth and amber eyes.
"Holy shit like mother like daughter apparently. Miyeong fucked a demon and it's Celine."
Someone choked.
Celine is a human, the Honmoon gave her the gift to mimic demons.
The little bundle in her arms is a half-demon.
There are... slight misunderstandings as Rumi grows up.
(Not that Celine ever corrects it, Rumi is just too cute!)

Reincarnation is nothing, press B to make Bobby slay demon. by Dem0nic_Child

Summary
"Yes yes, I know you girls are tired from the dancing—" and demon hunting "—so I'm giving you three a week long vacation!" He exclaimed, his phone on his ear as he summoned a bat and swung.
A squeal was heard, probably Zoey. "Thank you Bobby! You're the best!"
He laughed. "Anytime!" He ended the call, pocketing his phone before putting a foot on the demon's chest, his expression blank.
He equipped a pistol from his inventory, a surpressor attached. He aimed at the beaten demon.
"Tell Gwi-ma to go fuck himself."
TL;DR: Someone reincarnates as Bobby, has game mechanics, proceeds to live life normally until he meets Celine and HUNTR/X, and makes sure that he's there for them.
Demons are NOT ready for a manager who emotionally adopted three demon hunters (and an old one).

Summary
Mafia scrambled and fell onto the floor, earning startled looks that quickly stared at her.
"Maff? You alri—"
"ZOEY REALIZED I LOOKED LIKE RUMI." She interrupted Genderbent, who almost dropped the plate of food he was carrying.
Blind!Rumi snorted. "What, like, she thinks you're a masculine cosplayer? You ARE masculine after all." She asked. Mafia shook her head.
"No." She stuttered a breath. "She literally realized I looked exactly like her. My head structure, at least. She narrowed her eyes after I gave an excuse."
Everyone went silent.
"Shit."
Seven people became Rumi and managed to hide in the penthouse with the help of the Rumi from the world that they're currently stuck in. They've been floor neighbors ever since but never saw each other— specifically, Zoey and Mira never see them clearly.
Unfortunately that changes when Zoey sees one face to face, and becomes curious and suspicious to why one of them looks like Rumi, but more muscular with a different hair and eye color.

Summary
What if Rumi was a bit more demon-like? Pointy ears, sharper teeth, claws, all in her human form?
What if in her demon form, because of how secretly powerful she is among demons, demons hesitate going into South Korea?

Summary
Overdrive interrupts canon while maintaining the episodes. She's not part of Marinette's school and can't be in the building because she's an adult that doesn't exist at all in the system.
Cue the chaos she tries to contain; beating the shit out of certain akumas, going a bit feral, and acting like a nomu and scaring the shit out of Hawkmoth and Mayura by looking scarier than any akumas they've made.

Summary
What if when Katarina remembers her past life, someone was transported into her body, and now they have to work together in one body?
Katarina Claes, a 17 year old Japanese highschool girl who was obssessed with the Fortune Lover otome game with her best friend.
Rowan, a 36 year old Japanese reincarnator who has been into different worlds a hundreds of thousands of times, and was obssessed with the RPG game Fate's Darling.
Maybe their shared body slowly changes. Maybe it stays the same as canon. Or maybe—
Maybe Rowan's old appearance starts to appear through Katarina's appearance.
