Piecing all the anime series and manga history in chronological order.

Darker than Black: The Black Contractor
We are introduced to the world of contractors and Hei. This series ends with Hei and Yin on the run from the Syndicate.

Darker than Black: Jet Black Flower
This manga probably fits in here. We are brought on an investigation into the mysterious jet black flowers found in the gate. Hei and Yin are still in Japan.
The ongoing OVA series Darker than Black Gaiden continues where the first series left off to fill us in on what happened between Hei and Yin after the first season. Hei and Yin have escaped from Japan but are still on the run from the Syndicate. Yin’s powers begin to awaken.
