This is a posable action figure from the Nendoroid series.
From the Good Smile Company website:
"I said... don't... come any... closer..."
From the popular browser game "Kantai Collection -KanColle-" comes a Nendoroid of the Abyssal warship, "Northern Princess"! The enemy ship looks as adorable as ever, but don't be fooled by her appearance - she is equipped with all sorts of highly dangerous weaponry which has all been faithfully recreated in Nendoroid size! the batteries on her main turret can even be moved by rotating the runway on the side!
Optional parts include two of the rather peculiar aircraft that fly by her side, as well as the 'Zero' plane that she hold in her hands. Additionally, she also comes with parts that allow you to recreate certain parts of her special Christmas version that was seen during the Christmas event in December 2014.
Three expression parts are also included - her standard expression, a shouting expression and a cute expression with upturned eyes. Various different parts and expressions to create the Northern Princess you want by your side!
Note: This Nendoroid includes a normal Nendoroid stand only. The Special Nendoroid Stand featuring an ocean wave pattern is not included.
