The two-part-OVA was released in three different versions in Japan.
Version I: everything is split up to the actual episodes (incl. the pixelated sex scenes).
Version II: the so-called International Version. The sex scenes have been entirely removed. The studio / director also intended to do that for the release on the international market.
Version III: the third version is the actual International Version but the episodes have been cut low to a movie (the opening and final credits between the episodes are missing). The erotic scenes are missing as well. In the US, the International Version is also available without any censoring (no pixels).
