Fleeing from the consequences of his decision at the Hell's Gate, superpowered Contractor Hei and his companion Yin take refuge in a quiet inn, adopting the guise of a married couple in order to not draw suspicion. In an attempt to recover from recent events, Hei befriends the inn's other guests. He discovers that one of them is a fellow Contractor tasked with killing him. Their resulting encounter spells disaster for both Hei and Yin, who are forced to fight for their lives and grapple with the emotional wounds sustained in their previous life together.

I'll keep this short: Anyone who is a fan of Darker than Black NEEDS to find a way to watch these 4 episodes; they are crucial to understanding so many things about the series, including several things that didn't make sense in season 2, the relationship between Hei and Yin, and Hei's character development.

The OVA bridges the gap between seasons 1 and 2, explaining what happened to Hei and Yin during that time, and not only is this information vital to the plot, it is incredibly entertaining. This OVA is 4 episodes of pure awesome, as we finally ...

I really liked Darker Than Black. Not loved, just liked. What made me fall in love with the entire series was Gaiden. An OVA bridging the gap between the first and second seasons, it did not disappoint.

Story - 10:

A fantastic mix ...

Good: Fills the gap between seasons 1 & 2

This four part OVA can be summarized as a “couple on the run” sort of story. Hei and Yin are trying to survive daily life ...
