This Mikasa Ackerman figure is released by Funko in their POP! x Attack on Titan vinyl figure series.

Funko POP! is a crossover vinyl figure series by Funko and other famous pop culture franchises. Each POP! figure is about ~3" to ~5" tall and crafted in a Japanese anime/manga super-deformed style (NOTE: due to the unique design of each character, the actual size of the figures may be smaller or bigger than stated).

The Attack on Titan x POP! series features characters from the popular anime, which is set in a world where human lives in cities surrounded by enormous walls as a defense against the Titans, giant humanoid who seem to eat humans without reasons.

Mikasa Ackerman (??????????, also spelled as Mikasa Ackermann in the FUNimation sub of the anime) is the adoptive sister of Eren Yeager, and is the main female protagonist of the series. After her biological parents were murdered by human traffickers, she was rescued by Eren and lived with him and his mother and father for approximately a year before the fall of Wall Maria. Though she desires only to live a peaceful life with Eren, Mikasa chose to follow him into the military — where she is considered the best soldier among the 104th Training Corps — and later into the Survey Corps.
