Directed and produced by the sibling team behind indie darlings Poolside Man and I’m Really Good, The Demon is described as a black comedy horror film about a strange legend that haunts a Japanese village. Produced by the brother’s Foolish Piggies Films, the duo are looking to secure a festival premiere and post-production support. 　　“In [The Demon], I wanted to explore what exactly is the Oni (demon) that appears in countless legends,” said director Watanabe. “Are they gods, devils, the final form of humans, or something else? Where have they gone in modern society? If they are still alive, what happens when humans come in contact with them? These are the questions I asked as I wrote the script.”
