The First Haul boxset contains the censored version of *Secret of the Twilight Gemini*, which has most of its fanservice scenes removed. Whether that's a bother depends on your standpoint. If it is, there's always the choice of buying all of First Haul's specials and movie separately so you're sure you get the uncensored versions of all of them, or going for the First Haul boxset anyway and then buying the uncensored version of *Secret of the Twilight Gemini* separately.
