This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
From the anime series "Celestial Method" comes a Nendoroid of the 'saucer girl' Noel! She comes with a variety of option parts including a leaf umbrella, a cut out panel of Kirigon and a saucer cushion. She also comes with three expressions including a smiling face, a sulking face as well as the crying face with a gentle smile that was seen in episode 11 of the anime series.
The various optional parts allow you to recreate all sorts of scenes from the series! She even comes with a special 'saucer' part to display with her! Be sure to greet her with a warm smile when she joins your collection!
