Repack - Olivia Star Sessions Set 05rar

The .rar repack is tricky because repacks are often associated with piracy. If the original content is copyrighted, distributing a repack might be illegal. Also, the term "repack" sometimes refers to re-distributing content with changes, maybe removing unwanted parts or adding subtitles. But I need to confirm if Olivia Star Sessions Set 05 is legitimate or if the repack is an unauthorized version.
