"A Little Agency" sounds like it might be a company name or a project. "Little Melissa Pictures" could be a production company or a collection of works. "REPACK" is a term I've heard in software distribution, where a repack is a modified version of an original software that might remove bloatware or add features, but here it might be used in a different context. Maybe in media or entertainment, a repack could refer to a re-packaged version of content.
