This is a posable action figure from the Nendoroid series.
Adapted from Good Smile Company:
Aqua from "KONO SUBARASHII SEKAI NI SYUKUFUKU WO!" is joining the Nendoroid Swacchao series! They're Nendoroid sitting in a chair, making it easy to display them on desks, shelves or areas where you might need to save on space! They can be shown on practically any shelf, so get creative! Make sure to pick up the other KONOSUBA Swacchao Nendoroids, too!
