This is a posable action figure from the figma series.
From the Good Smile Company website:
From the anime series "LoveLive" comes a figma of the μ's member in charge of lyrics, Umi Sonoda!
Using the smooth yet posable joints of figma, you can act out a variety of different scenes.
Three expressions are included: a smiling expression, an angry expression to get upset with Honoka and an embarrassed expression that suits Umi-chan's personality perfectly.
Optional parts include her school bag, a quiver to show that she is a member of the Kyudo club and the diet plan from the second season of the anime.
Just like the previously announced LoveLive! figmas, she comes with two glow sticks of her image color.
An articulated figma stand is included, which allows various poses to be taken.
