This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
From the popular browser game that is celebrating its 4th anniversary in April 2017, "Kantai Collection -KanColle-" comes a Nendoroid of the first Fubuki-class special destroyer, Fubuki Kai-II! She comes with three face plates including a standard expression, combat expression and half-damaged expression.
The Nendoroid has been tuned to allow for more action scenes with additional joints added to her hips. She also includes a variety of effect parts including turret firing effect parts, torpedo effect parts, effect parts to display her gliding along the surface of the water, machine-gun water pillar effect parts as well as a smokescreen effect part allowing for all sorts of action scenes! Enjoy the 4th anniversary of KanColle together with the Nendoroid KanColle series, which has also been running for nearly four years!
