Phantom Quest Corp. (幽幻怪社, Yūgen Gaisha) is a comedy horror anime produced by Madhouse and Pioneer LDC. It was originally released as a four-episode original video animation (OVA) in Japan between August 25, 1994 and February 25, 1995. An English-dubbed version was released in North America by Pioneer (now Geneon Universal Entertainment) 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 Gaisha (often written as You-Gen-Kai-Sya) 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.In addition to the Phantom Quest Corp. OVA series, two soundtrack albums, a Japanese light novel, and a single-issue English manga also exist. Phantom Quest Corp. has been compared to the concurrent manga and anime Ghost Sweeper Mikami. The animation, comedy, and action sequences in Phantom Quest Corp. has been praised by critics. However, these same reviewers felt it lacked plot depth and character development due to its short length.
