This is a posable action figure from the Nendoroid series.

Adapted from Good Smile Company:

From the popular anime and manga series "My Hero Academia" comes a Nendoroid of the hero from class 1-A with a frog Quirk, Tsuyu Asui! She comes with three expressions including a standard face, a "Ribbit" expression for when she's using her Quirk, and a smiling expression with closed eyes.

Her aquatic hero costume has been faithfully recreated in Nendoroid size, and she even comes with a long tongue part as well as a "SPLASH!" text plate so you can pose her in any number of action scenes. Be sure to add her to your collection!
