Ask John: Where is Devil Hunter Yohko 4?

Question:
I bought Devil Hunter Yohko Collections 1 and 2, and I don’t notice any episode 4? I only see 1, 2, 3, 5, 6 and 4-ever which seems to be a music video? Was it not included in the collection for some reason?

Answer:
There is and isn’t actually a Devil Hunter Yohko 4. Likewise there technically isn’t a Devil Hunter Yohko 6. The music video is actually the fourth release in the series. AD Vision slightly re-named volumes 4 and 6 for their American release. The Japanese release order for the series is:

Mamono Hunter Yohko, released May 1, 1991
Mamono Hunter Yohko Part 2, released December 22, 1992
Mamono Hunter Yohko Part 3, released April 1, 1993
Mamono Hunter Yohko Super Music Clip, released December 21, 1993
Mamono Hunter Yohko 5: Kouin Haou no Ran, released July 1, 1994
Mamono Hunter Yohko² (Mamono Hunter Yohko Squared): Youko no Jijou, released July 1, 1995
