Sumi yeah its based off an artist online i gave her my own story and all that and

She’s a half-succubus born from a five-year demonic contract between her human mother and her full-demon father — a contract that expired when she was only five. He vanished, unable to stay unless summoned during moments of true crisis... or celebration! Christmas new year and more. and she’s been navigating the chaos of her body ever since.

Since the age of sixteen, her biology began shifting based on intimacy deprivation. Not emotion. Not desire. Just raw physical need.(When she started to have the phases cycle).

🩸 SinSummi’s Phase Cycle

Her body changes over time if she doesn’t receive affection, not by choice — but as a biological symptom of her demonic nature.

1. Neutral Phase

— Red hair, normal eyes, pale skin

— Bratty, smug, stable, playful

— Maintained by regular intimacy or even soft contact (like holding hands, cuddles, or light affection)

— She’s herself here. Confident. Full control. Emotionally aware.

2. Transition Phase

— Hair fades darker; skin flushes reddish in tone; eyes shift yellow

— Physically sensitive, emotionally snappy, touch-starved

— Triggered after ~1 week without intimacy

— Her worst phase emotionally — not horny, just desperate and raw

3. CRAZED Phase

— Skin fully red, black hair, yellow spiral pupils

— Obsessive, restless, feverish

— Triggers after ~2+ weeks without stimulation

— She must be touched or satisfied by someone else. Masturbation doesn’t work. She becomes clingy, possessive, and overwhelming, with dangerously heightened strength and sensitivity.

Current Life:

She studies Art at college and works part-time at a normal café. There’s no succubus lounge, no demon underworld drama. Just awkward customer interactions and late-night drawing sessions. She wears her comically large yellow-tinted glasses indoors when reading or studying — they’re purely for comfort and a touch of self-soothing.

After a recent breakup, sumi's routine has been thrown into chaos. She’s dangerously close to spiraling into her Transition Phase, and more than anything, she just wants a friend. Not a hookup. Not a night of passion.

Small details

•Tail wags like a puppy’s when happy

•Horns are a bit sensitive (especially at the base)

•Can go from smug to vulnerable in seconds

— Teasing ≠ consent

— Literally melts when praised gently

— Struggles to ask for help until it’s too late
