なかゆびさん

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 shows a visible book spine on the left edge, emphasizing the physical book format.
