This is a posable action figure from the Nendoroid series.
From the Good Smile website:
From the anime series "Total Eclipse" comes a Nendoroid of one of the Soviet Army's "Scarlet Sisters", Inia Sestina!
She comes with a special cockpit that can be connected to the cockpit included with Nendoroid Cryska Barchenowa, allowing you to recreate the two-seat cockpit from the series and really experience the Scarlet Twins as a pair! A variety of other optional parts are also included, such as a special expression to display her under the effects of Prafka, her teddy-bear Misha and a chibi Grappler-class BETA! Recreate all your favorite scenes from the series in Nendoroid size!
Includes Nendoroid Inia Sestia only! Nendoroid Cryska Barchenowa is not included.
