I personally would prefer a Figma version of Mirai as I would play n pose her and carry her around with me. I hear that many readers don't like the joints though.
To be honest, when I first saw the Figma line, I wasn't a fan of the joints either until I started to acquire them. One really starts to appreciate how articulate they are. I guess owning Figma's has got me interested in the Dollfies.
So the question is which type of figure would you like to see Mirai in - Figma, Nendoroid or scale figure?
