Summary
Vaggie's secret is out.. How will everyone react to knowing an exorcist has been among them this whole time?
-

Summary
If there was one thing Vaggie enjoyed most. It was driving her sweet innocent girlfriend towards the breaking point. The fallen angel would never get used to Charlie's beautiful demon form, and a part of her never wanted to, but she always longed to drag it out. Good thing she knew just how to make the Princess of Hell bare her teeth and show off those pretty horns. (I'm so bad at this)

Summary
Zoey’s the center of Huntr/x—onstage, in battle, in the group chat—right up until a demon tears her open and she starts bleeding out in the rain.
With no handlers, no hospital, and no good choices, Rumi finally drops the act and shows Mira what she really is: half-demon, with blood that can stitch a dying girl back together.
One desperate ritual later, Zoey’s alive… and Rumi is left with a matching scar and a terrifying side effect she doesn’t understand, a new bond humming under her skin that might save them—or ruin everything they’ve built.

Summary
What happens when your needy cat-wife goes into heat and your inferior biology can't manage to keep up with her?
Glorious improvisation happens.
Or: Adora has Entrapta enchant a phallus with the ability to feel sensation and then has the inventor whipping up a bracelet that acts as an aphrodisiac for the duration it's worn. I hope you know where I'm going with this.
(Now featuring custom fanart from Batatadeuces!)

Summary
Rumi is startled awake by a sudden noise of something dropping with a thud onto the floor space right in front of her.
Right at the moment, the smell hits her immediately.
Inside her steel cage, on the floor in front of her are several cleanly cut pieces of greasy cooked meat. The meat pieces looked cold, as if someone had sneakily taken them from a warm plate and hidden it away for hours.
Zoey's doing.

Summary
Zoey's been acting weird around Rumi. Not hostile, not cold – just... twitchy. Like she’s been short-circuiting every time Rumi gets too close.
Ever since the truth was revealed about the patterns, things haven’t been the same. Especially not with the way Zoey’s been dodging eye contact, avoiding touch, and turning red like she’s caught a fever.
Rumi thinks Zoey might be scared of her. Zoey thinks she might explode if Rumi flexes one more time.
One very hot demon girl, one disaster lesbian, and all the emotional repression monsterfucking can easily fix.

Summary
“Hmm.” Zoey looked back at her notebook, skimming her finger down to the bottom of the page as she scanned her scribbled notes. “Idea thirty: pretend to date Rumi.”
“You or Mira?”
“Both of us.”
Rumi snorted. “How would that help?”
“No, hold on,” Mira said, a smile slowly spreading across her face. “I think she’s onto something here.”
---
Zoey and Mira both have problems, and the obvious solution is pretending to date Rumi.
