This is a completed and painted, fixed-pose figure.
From the Good Smile Company website:
From the popular Dengeki Bunko series with an anime on the way "Eromanga Sensei" comes a scale figure of the main character's younger sister, Sagiri Izumi! The figure is based on the cover illustration of the first light novel, and features Sagiri with her tablet in hand, carefully studying the source material in front of her.
The tightly closed mouth, soft-looking cheeks, loose hoodie and long bare legs have all been faithfully sculpted to ensure the world's cutest little sister looks adorable in your collection!
