It aired in the United States on January 4, 1998 on the Fox network. "Kitsunegari" earned a Nielsen household rating of 11.6, being watched by 19.75 million people in its initial broadcast. The episode received mixed reviews from television critics.
The show centers on FBI Special Agents Fox Mulder ( David Duchovny) and Dana Scully (Gillian Anderson) who work on cases linked to the paranormal, called X-Files. Mulder is a believer in the paranormal, while the skeptical Scully has been assigned to debunk his work. In this episode, Mulder and Scully search for the infamous killer Robert "Pusher" Modell ( Robert Wisden)—a human with the ability to force his will onto others—after he escapes from prison. The agents soon discover that he is not their only concern; he has a sister, and she is just as capable of mind-control as he is.
"Kitsunegari" serves as a sequel to the third season episode " Pusher". The episode's title means "Fox hunt" in Japanese. Minear's original story for the episode was one where a convicted criminal who happened to be an atheist would have heard the voice of God, commanding him to kill a truly evil man. Series creator Frank Spotnitz suggested that Minear should use fan favorite Robert Modell.
