This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
Joining the new 'Nendoroid Co-de' brand of Nendoroids is Mirei Minami from the popular anime PriPara, wearing her Candy Alamode Cyalume Co-de! The outfit is the cyalume co-de of the bright and cheerful 'Candy Alamode' brand that suits Mirei's colorful personality so well! Be sure to display her together with the previously announced Laala Manaka and upcoming Sophie Hojo Nendoroid Co-de figures, which will allow for all sorts of different outfit combinations!
Additionally, an original special 'Friends Ticket' that can be used in the PriPara game will also be included!
