Update: Since the time of this post, Infinity Studio have revealed the painted prototype of their Zenitsu statue at Wonder Festival 2021. Learn more and check out updated photos!
Infinity Studio have announced a statue of Zenitsu Agatsuma from Demon Slayer: Kimetsu no Yaiba along with a work in progress photo of the upcoming release. In the photo they posted, you can see Zenitsu performing what appears to be his First Form: Thunderclap and Flash. For those of you who aren't aware, Infinity Studio makes licensed statues.
As of now, details about the Zenitsu statue, such as its scale and preorder date, have yet to be revealed by Infinity Studio. The anime statues that Infinity Studio previously announced, like their Deidara statue from Naruto Shippuden, are in 1/6 scale, but scales can and do vary from license to license.
We will continue to update this post as more is revealed. Until then, you can check out Infinity Studio's WIP photo for their Demon Slayer: Kimetsu no Yaiba Zenitsu statue below!
