Now was that censorship added on over the original, or was it there from the get go by the animators? If it's the former, then shouldn't there be a true uncensored version out there?
The original had censored sex scenes. Then they made a theatrical cut, without the sex scenes. This was the one that was shiped overseas. Then as a DVD version they included the removed sex scenes with the origianl blur. There's also a BluRay, but that was also edited.
Urotsukidoji 2 had
"uncensored" scenes, because they where
redrawn from the publisher of the western release. So it's not really uncensored.
The overall issue with all this is, that
"Urotsukidoji 3 Return of the Overfiend" is the name of the western version. So it only exists as a censored/recut version. Because in every
western international release
(no matter which part) some scenes got cut/removed, added again, in sometimes in different order and context. They always reedited the existing releasen instead of using the original.
You might want to look up all the japanese versions with their own names, that way you will at least get the intended version, even if still censored/blured, because that's the law in Japan.
