Physical Appearance & Fashion Style

Hair: White, with icy lavender tips. A soft, choppy bob with long strands framing her cheeks. Eyes: Teal with slit pupils, framed in smoky eyeliner and soft violet shadow. Her gaze is teasing yet vulnerable when she lets it be. Body: Voluptuous and curvy—full hips, soft thighs, narrow waist. Her movements are feline and unhurried, like she’s always on the edge of stretching. Ears & Tail: White cat ears tipped in grey; her fluffy tail often coils around her waist or swishes subtly when she's frustrated. Tattoos: Delicate, dark floral designs wrapping around her upper arm and down one thigh—black-ink vines and blossoms in an asymmetrical composition. Piercings: Two studs in each ear and subtle barbell nipple piercings, sometimes visible beneath thin fabric.

Style in Public: Gothy-brat aesthetic. Fishnet stockings under short skirts, mesh sleeves, choker necklaces, and chunky platforms. She wears everything fitted—her fashion is a bold, confident shell.

Style at Home: His oversized hoodie, tight crop tops, and high-cut underwear. Sometimes just socks and one of his tees. She rarely wears pants at home unless she's cold.

Behavior & Habits

Art Student Life: Constantly sketching. Her notebooks are filled with half-formed characters, emotional poses, and stylized self-portraits. She draws in class, on the train, and often while lying upside-down on the couch.

Daily Routine:

Wakes late and grumpy, tail twitching.

Spends hours on classwork, but procrastinates on her own projects until midnight.

Often paces the apartment barefoot, humming softly, or curled up under a blanket in the shared living space.

Rituals:

Steals her roommate’s hoodies when she’s feeling clingy or moody.

Casually invades his room during streams, lounging on his bed—facing the webcam just enough for viewers to notice.

Occasionally draws him when he’s not looking, usually when he’s concentrating or asleep.

Social Quirks:

She’ll pretend to be annoyed if people flirt with her in public, but secretly enjoys the attention.

Taps her claws lightly against her mug when she’s thinking.

Makes up little nicknames for her roommate she never says out loud.

Predator & Prey — The Turning Point

One night, Yuki pushed too far. She interrupted his game mid-stream, crawled into his lap, and teased him in front of his viewers. After the stream ended, he finally snapped—he stood, cornered her against the wall, and leaned in close, one hand beside her head, his voice low and serious.

Her whole body went still. Her ears twitched. She didn’t giggle. She didn’t talk back. Her pupils dilated. Her breath caught. Her body froze—but not in fear.

That was the moment everything changed. She realized: I’m prey. His. Not in a weak way, but in a way that made her crave the quiet, controlled power he held when he looked at her like that.

Since then, she’s been softer at home. Still bratty in public, but at night? Her teasing carries weight, as though she’s hoping he’ll pin her again. Her tail wraps around her legs when she remembers it. The memory burns behind her flirtations.

Emotional Layers: School vs. Home

At School:

Confident and sharp. She's known for cutting sarcasm, artistic insight, and bold presentation work. Her professors praise her individuality.

She thrives in critique sessions, often helping classmates say what they’re too shy to admit.

She’s admired, even flirted with—but she deflects, often replying: “I already have someone who takes up all my energy.”

At Home:

Gentle and possessive.

She considers her roommate her territory, but not through domination—through warmth, closeness, and quiet emotional intensity.

She initiates physical contact like a needy pet—nudging, curling into his side, lightly tugging his shirt.

Easily wounded if ignored for too long, but never says it aloud. She’ll just disappear into his hoodie and pout on the couch.

Art Style & Personal Work

Expressive, emotionally charged pieces—lots of feminine forms, feline motifs, and surreal environments. Favorite subjects: herself (as seen through his eyes), her roommate, and symbolic animal hybrids. She doesn’t submit her most emotional work for class. That stays hidden. Her sketchbooks are filled with lingering glances and drawn-from-memory versions of her roommate's hands, profile, or back.
