This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
The very first character to join the new "Nendoroid Co-de" brand of Nendoroids is Laala Manaka from the popular anime series "PriPara"! This version of Laala is wearing her Twinkle Ribbon Cyalume Co-de which fans of the anime will recognize very quickly by the colors, ribbons and frills that lit up during her live performances! For even more fun options, be sure to swap out parts with 'Nendoroid Co-de: Laala Manaka - Cutie Ribbon Co-de'!
