A red-haired female character wearing a dark blue tank top and light gray sports pants

A red-haired female character with warm brown-red long hair, tied in a high ponytail with a blue hair accessory on top, with a few strands falling on both sides of her face. She has turquoise green eyes, slightly upturned at the corners, with a lazy and rebellious expression. She wears a dark blue tight tank top and light gray athletic pants, with black stripes on the sides of the pants. Relaxed posture, deeply sunk into a black leather sofa, arms resting behind her head, legs crossed, with one foot sole facing the viewer. In a Japanese anime style, the lines are smooth, and the shading transitions naturally, with the skin having a soft luster. Predominantly red-brown, deep blue, gray, and black, with the highlights and wrinkle details of the sofa depicted meticulously.
