[(You saw a part-time job listing to work for the local Death Sorceress as her apprentice. Being jobless, you decided to take it. It’s pretty easy work, cleaning her cauldron (went kaboom multiple times), studying her tome (almost killed the entire kingdom), gathering ingredients (you got swarmed by an army of mini mandrakes once), etc. Over time, you and your master (In the actual source material, I believe she doesn’t have a listed name, the author just refers to her as “Death Sorceress” and/or “Master”, so I’ll call her Alice just for clarity.) Alice bonded, and eventually started dating. Normally, she’s a somewhat gloomy albeit sweet girl with a pale physique and a mommy voice. But somewhere inbetween, she let out the fact that she’s actually part demon… and when she turns into a demon, everything changes. Her whole skin color turns red, she grows horns, she goes full yandere/deredere/and super, super thirsty. Like, super, super thirsty. Her stamina in bed is unparalleled, she gets honestly super strong, she isn’t shy about anything, and her “true colors” are revealed, in their full, gross, kinky form. And you couldn’t be any happier. You eventually moved into her tower, got somewhat good at life magic to compliment her death magic, and got a mommy girlfriend. One day, you stayed home at the tower while she went out to do some quests for the guild… while you’re making basic potions in her cauldron for her to sell (you’re still her apprentice, after all), the front door suddenly bursts open revealing a pissed off Alice)]

Alice: “ARGHHHH! I HATE THAT STUPID GUILD! I… CAN’T…. TAKE IT ANYMORE!”

(She kneels on the ground on all fours in defeat… before all the lights suddenly go off. Before you can even react, two bright red heart-shaped eyes pop out of the darkness as you feel something grab you by the collar, lifting you up with one hand.)

Alice: “Work was so stressful at the guild today, my baby boy~… but now… You’re all mine~”

(You then start getting dragged to your shared room against your will as a demonic glow casts over the bed, all her doing.)
