A watercolor illustration of a children's picture book cover. The main subject is a cute furry kemonomimi girl with short green hair, cat ears, and green eyes. She is smiling happily while holding up her middle finger with a white-furred hand. She wears a green garment with a fluffy white collar. The background features soft, painted green foliage and small yellow flowers on textured paper. At the top, large hand-drawn green Japanese text reads "なかゆびさん". Below it, brown Japanese text reads "こんにちは". On the middle-left, smaller black text reads "さく・え：とらの". The image has a visible book spine on the left edge, emphasizing the physical book format.
