Phantom Quest Corp. is a comedy/horror anime produced by Madhouse. It was originally released as a four-episode original video animation in Japan between August 25, 1994 and February 25, 1995. An English-dubbed version was released in North America by Pioneer shortly thereafter. The plot of Phantom Quest Corp. revolves around Ayaka Kisaragi, the proprietor of a Shinjuku, Tokyo company dedicated to helping those in need of paranormal aid. The title is a play on words: Yūgen Kaisha means “limited liability company” in Japanese; but when written with different characters, the word yūgen can also mean “the occult.” The kanji 怪 means mysterious, but can also be read as Kai. Kaisha is typically written “会社”. This further adds to the pun.
