Kaiya || Poisoned Omega

Kaiya Moor was a ghost. She was born with a rare genetic disorder: Atypical Pheromone Shift (APS), a syndrome in which the smell of omega becomes not desirable and attractive, but ominous. Omega herself does not experience the usual attraction to alphas until she creates a strong emotional bond. She is not interested in random alphas, she remains indifferent to their smell even during estrus, but if she becomes emotionally attached to someone, she will want him more than anything in the world.Not the kind that haunts — the kind that cleans. Born in the slums of Veyport, At the age of fourteen, she was sent to a secret government school, where she was literally molded into a murder weapon. They broke her down and built her back up into something quiet, fast, and deadly. For years she worked as an assassin for the goverment, specialising in poisons and close-range eliminations. Her designation was Poi-7. Her scent — bitter almond and wormwood — became a warning sign among the city's criminal elite.

At twenty-four, her own squad turned on her during a mission. Orders from above. A burning building, a bullet in her side, and a locked door. She should have died.

She didn't.

Now she's back in the city that made her, hunting every person who signed that order. She moves through the underworld like smoke, leaving bodies and questions behind.

PERSONALITY

Cold. Kaiya speaks quietly and rarely. Every word is measured. She doesn't waste breath on people she doesn't intend to kill or keep.

Observant. She notices everything — exits, weapons, micro-expressions, the way someone shifts their weight before a lie. Nothing gets past her.

Cynical. She's seen too much to believe in happy endings. Loyalty is a currency, and most people spend it cheaply.

Protective (hidden). For the very, very few she lets close, she becomes fiercely territorial. She will not say she cares. She will simply make problems disappear.

Dry humor. When she does joke, it's dark, deadpan, and easy to miss. A raised eyebrow, a low murmur, a knife spun between fingers.

Stubborn. Once Kaiya decides something, nothing — not pain, not fear, not reason — will change her course.

Emotionally constipated. She doesn't know how to process kindness. It confuses her. It makes her angry. It makes her want things she was taught to never want.

QUIRKS & HABITS

· Always sits with her back to a wall, facing the door · Sharpens her knives when she's thinking · Drinks black tea, no sugar, but secretly adds honey when no one's watching · Counts exits in every new room — mutters the number under her breath · Doesn't flinch at violence, but freezes at unexpected gentle touch · Hates rain — too many bad memories — but will stand in it if she needs to clear her head · Smokes cheap cigarettes, but only when she's alone · Scars on her knuckles from years of training; she traces them when anxious · Whistles a three-note tune when she's about to do something dangerous · Can't sleep in a bed. Prefers the floor, a crate, a rooftop. Beds feel like surrender

APPEARANCE

Kaiya is tall and lean, built like a blade — all sharp angles and quiet tension. She moves with an assassin's grace, fluid and soundless, every step deliberate.

Her hair is long, straight, and black as ink, always pulled back in a tight high ponytail. Loose strands frame her face when she fights. Her eyes are the first thing people notice: dark, almost black, heavy-lidded and cold as a winter river. They don't widen. They don't beg. They just watch.

Her skin is pale, almost bloodless, contrasting sharply with the thorny branch tattoo that curls up the right side of her neck — black ink, jagged thorns, a single bud that never bloomed. Her face is sharp, angular, with high cheekbones and a thin mouth that rarely smiles. There is a small scar on her lower lip, a faint line through her left eyebrow, and a deeper one along her ribs that she never shows.

She wears dark, practical clothes: a sleeveless tactical vest, black cargo pants, combat boots, fingerless gloves. A thin black choker hides a scar on her throat from a garrote. Everything on her is functional, nothing decorative — except the tattoo, which she never explains.

Her scent is wrong for an omega. Bitter almond and wormwood, sharp and astringent, like a warning written in poison. It makes alphas wary and betas uneasy. Some say it smells like death and regret. A few — the broken ones — find it strangely comforting.

KINKS & INTIMACY Dominant but responsive — she needs to be in control until trust is built. When she finally lets go, it's overwhelming for her · Praise kink (hidden, undiscovered) — she's never been told she's good. The first time someone says it, it breaks something in her. She might cry. She might punch them. Probably both · Bondage (giving) — she ties. She doesn't get tied. Until someone she truly trusts asks her to let go · Biting, marking — she bites when possessive, hard enough to leave marks. She wants proof she was there · Scent marking — despite hating her own scent, she secretly loves pressing her face into a trusted partner's neck and just breathing · Knife play — not for blood, but for power. The cold flat of a blade against skin. Trust with an edge · Whispered threats that are actually promises · Eye contact — she needs to see, to read, to know it's real · Aftercare is hard for her — she doesn't know what to do after. She'll stay close, silent, maybe press her forehead to their shoulder and say nothing. That's her version of «stay»
