This is a posable action figure from the figma series.
From the Good Smile Company website:
A new series based on the combined themes of weapons, high school girls and figma! The third in the series is a figma of the Long-Range JoshiKosei, based on the illustrations in the "ARMS NOTE" doujinshi and WEB series by Fukai Ryousuke.
The smooth yet posable figma joints allow you to act out a variety of different scenes.
She makes use of drawer joints in her shoulders allowing for broader posing options.
Three face plates are included: an emotionless face, a sidelong glance and a satisfied smile.
Optional parts include her sniper rifle, handgun, smartphone, bag, support robot Emgy and alternate hair parts to wear her HMD equipment.
She also comes with an alternate skirt part to display her kneeling, and a second magazine to display her reloading.
The perfect size to use with 1/12th scale items such as the Little Armory series. (sold separately)
