This Tani vinyl figure is released by Funko in their POP! Games x Ni no Kuni vinyl figure series.
Funko POP! is a crossover vinyl figure series by Funko and other famous franchises such as Disney, Pixar, DC Comics, Marvel Comics, Simpsons, South Park, Uglydoll, etc. 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 POP! Games x Ni no Kuni II: Revenant Kingdom series features characters from the RPG game. Players of the game control Evan Pettiwhisker Tildrum, a young king who was usurped from his castle and sets out to reclaim his kingdom. While players can freely navigate Evan throughout the game's open world, other characters can be controlled during battles against enemies. During these battles, players use magical abilities and elemental creatures known as "Higgledies", which are used to cast spells.
