The 3D CG anime film Friends: Mononoke Shima no Naki is directed by Takashi Yamazaki, inspired by a "tear-jerker" fairy tale by Hirosuke Hamada titled "Naita Aka-Oni". The movie, however, will tell a new story for kids, about Naki and Gunjou - two friends living on Mononoke Shima, who cross paths with a human child.
