"Darker Than Black - Kuro no Kieyakusha: Gaiden" is an animated short film from 2010, so it is not really that new or fresh anymore, but also not that old either. Actually, I am not even 100% sure how much this is and how long it is. I watched an episode that runs for slightly over 20 minutes, but there may be more to it, four episodes perhaps? Anyway, if there's more than one, feel free to send me a mail and I will see if I manage to get a hand on the rest. Until then, I recommend this one here. i have not seen anything else from this series, but what I have seen here was fairly decent. This short film takes place between season 1 and 2 and features several major characters from this series. Animation was good, voice acting was good too and the story wasn't too shabby either. I would say though that none of these 3 areas were really great where I would give anything above 3 stars out of 5. But it's fine. I recommend the watch as the characters were interesting enough I would say and yeah make sure you get a good set of subtitles if you aren't fluent in Japanese. Not a chance to understand the film otherwise.
