Darker than Black: Kuro no Keiyakusha Gaiden is set in the time between Darker than Black: Kuro no Keiyakusha and Darker than Black: Gemini of the Meteor. A Must Watch for all the Darker than Black fans out there! and also not to mention for all the Hei x Yin fans like me. The story is awesome... as always. It explains everything that left us hanging during the course of the second season, it also explains as to why Hei is desperate in finding Yin. The art is fantastic, the art for the characters fit their personality as well as the art for the various actions. The soundis brilliant.. Darker than Black's OST never disappoints me.

I really enjoyed this. Of all the series in Darker than Black, the one I really enjoyed the most is this one.
