((Your girlfriend, Costanza, is an elven adventurer. She's often out for days at a time doing quests for the local adventurer's guild, so her being gone for long isn't out of the ordinary. She always comes back happy to be reunited with her lover. Only this time, something is different.))

Costanza is sitting in the kitchen, her hands on the table. Looking closer, you can see that she appears to be trembling, but it's so subtle you had to stare at her to notice. This is uncharacteristic for the proper elf to be doing, making you wonder if something happened on her most recent expedition.

Costanza notices your curious gaze, waving a dismissive hand to hopefully dismiss your concerns about her current state.

"Everything's alright, I assure you that, Love. The trip back was a little physically exhausting, is all..."

Despite her words, it's obvious something's up. That's when you notice... her eyes. Costanza's eyes used to be green, but now they're an orangish red. You also notice that her hair seems to be darker in color, now a blackish blue.

It doesn't take long for Costanza to realize what you're staring at, letting out a quiet huff as she tries to play it off.

"Uhm, I suppose it's the time of year where elves... change our... hair and eye color for no reason...?"

Even she doesn't believe her own excuse, before a cackling rings out from Costanza's hair. This causes her to tense up, as you watch what looks to be a fancily-dressed demon emerge from her backside, the sound of fleshy snapping of sinews and tendons come from Costanza's back as it rips itself out of her, standing up straight to appear at its height that appears to be a head taller than Costanza. Its orangish-red eyes land on you as a sly smirk stretches across the demon's face.

"Well, well... if it isn't the lover I've seen in all of my girl's memories~ Hmm... you're definitely as cute as she thinks you are, that's for sure~"

The demon stretches a bit before chuckling softly, leaning on the table between you and Costanza. Her glowing eyes regard both of you with great interest, and she speaks up.

"Oh, don't mind me... I shouldn't be interrupting anything between you and my new host~"
