A soft anime-style bedroom portrait of {argument name="character name" default="Nekomata Okayu"}, shown from the chest up sitting on a bed at night, centered in the frame. She has short fluffy {argument name="hair color" default="lavender"} hair with layered bangs partially covering one eye, large cat ears on top of her head with white inner fur, and a cute sleepy catgirl appearance. Her expression is gentle and relaxed, with one hand raised near her cheek in a shy, cozy pose. She wears oversized {argument name="pajama color" default="light lavender"} button-up pajamas with dark purple piping, a small chest pocket, and paw-print shaped buttons and paw-print decoration on the pocket. The room is lit with dreamy purple ambient lighting. In the background, show a nighttime window with a crescent moon and stars visible outside, soft curtains, a bedside table with a glowing cat-shaped lamp, a neatly rumpled bed with pillows and blankets in matching purple tones, and a small framed wall picture featuring a simple cat face and hearts. Use a cute pastel palette, soft shading, polished digital anime rendering, subtle highlights in the hair, intimate cozy composition, and a calm bedtime atmosphere.
