The American release has been done under two companies. First by NuTech Digital which would release the box set on July 2, 2004. In 2006, as a result of the lawsuit against Nutech Digital by Ken Groove Media alleging breach of contract Adult Source Media acquired the rights to Dark Shell as a result.^[2] The case concerned breach of contract and Ken Grove Media and concerned 34 titles, which were sold online and under a contract price.^[3] A second release was done by Adult Source Media in 2006.

Beveridge of Mania offered a mixed review of the work. The content and bleak setting with sex and extreme violence would appeal to few viewers.^[4] The graphics and character development were only average, but was filled with negativity from the characters.^[4] The localization conducted by NuTech was criticized for the timing of the subtitles to the English dub which resulted in scenes of dialogue being separated from the speaker and the misspellings of the subtitles.^[4] This opinion was backed up by Saito who would not recommend the OVA because of its excessive violence, noting that the women are raped and killed after and during sex.^[5]
