Ghost Sweeper Mikami (lost English dub of anime series; 1993-1994)
"Gōsuto Suīpā Mikami", or "Ghost Sweeper Mikami", is a Japanese comedic supernatural manga series written and illustrated by author Takashi Shiina. The series ran from 1991 to 1999 and was published in the weekly manga magazine Shōnen Sunday; even winning Shogakukan Manga Award for best shōnen manga.
From 1993 to 1994 the series was adapted as 45-episode anime by Toei Animation, even including the release of a full 1 hour length feature film on August 24, 1994. The film is notable for having an American English dub release by Manga Entertainment, known for dubbing anime films such as "Akira" and "Lupin III: Bye Bye Liberty in Crisis". Although, not many are fully of aware of the English-language dub for the anime television series; produced in Southeast Asia and aired on Filipino channel AXN (Asia).
The dub's "supposed" existence was brought to light when a thread post  on the website Behind the Voice Actors was created, inquiring more information on the dub's existence. The user had provided links to a Blogspot  account that mainly uploaded information/clips on Japanese anime broadcast in the Philippines, both dubbed and subbed. All of the YouTube clips, however, have been taken down due to copyright claims, but the one piece of information that has been gathered of this dub's existence is that was supposedly dubbed by a dubbing company based in Hong Kong. On the previously mentioned forum, the other user confirmed that it could have been a possible product of the well known Southeast Asian dubbing company, Animax Asia (who have an office based in Hong Kong).
From 2004 to 2010, AXN (Asia) acquired and broadcasted anime programming from Animax, dubbed in the English language, so it is very likely that one of these acquired shows was "Ghost Sweeper Mikami"'s English dub.
