Hand-drawn line art style with extensive cross-hatching for fur shadows and low saturation clean colors. A black-haired girl with bangs and brown eyes wears a light gray sailor uniform with light blue scarf, hands folded in front. Behind her stands a giant gray-white long-haired cat with black facial markings and green eyes looking forward. Pure white background emphasizing the scale contrast between human and cat. Even flat lighting creates a quiet, slightly surreal and fantastical atmosphere with meticulous ink work.
