This mini is a fantastic looking japanese demon made by Hazgaard Editions for the Okko board game. Okko is a french comic book that takes place in Pajan , a fantasy version of medieval Japan. The game is played with cardboard cutouts but at some point an additional range of metal miniatures was released. Sadly the range is very small and I'm not sure if they are even still in production. I bought some minis last year and started painting them recently. The minis are sculpted and cast very well. Most of them are multi-part miniatures and need to be build together, which can be quite fiddly because of the very fragile nature of them.
Here is a comparison between the Okko mini and a Reaper samurai
