Niramu, who has just been appointed as a DGP producer, goes to the Sengoku period in Japan for his first job. There, he learns about the "realism" of this era from the navigator, Miiru, and savors the valuable experience. Meanwhile, Nemeru, a veteran producer who has been active in DGP since its inception, makes a suspicious move... Realism and fiction - what is necessary for true entertainment?
Unfortunately the movie Geats Extra: Kamen Rider Gazer is not yet available on HBO Max.
