Also seen above is Sosuke Ikematsu (The Last Samurai, MOZU) as Ryuzaki wearing a mask in a recent promotional image for the film. That image was distributed during the recently concluded 2016 Berlin International Film Festival. Only 10,000 copies of Screen Daily featuring the image above, and it was quickly sold out.
The six Death Note rule is something that was established in the series' lore, and this is the first time this aspect of the lore is explored. In short, we will possibly see up to six Shinigami in the film.
The upcoming Death Note film is directed by by Shinsuke Sato (Gantz) and is set for a fall 2016 release.
