MUKD-105 - Secret Box: The Pure Girls You've Been Waiting For, Rie & Maki

I thought this was just a compilation of leftovers or things that couldn't be released as standalone works, but it actually feels better produced than most solo works. The cast is also top-tier for this series. It's a pairing of two very different characters, and both have their own charm. Honestly, some regular releases are worse than this, so it's a two-for-one deal. Personally, I'd rather watch solo works of these performers than some of the other stuff out there.
