Also made by Studio Bones. Has a similar concept of social outcasts (Contractors/Wolves) of whose existence the general public is unaware, posing as humans and trying to survive any way they can.
They are both dark anime,and in both of them,races with supernatural powers,hunted by the normal humans, are trying to find their benediction.
In Darker than Black,they are the contractors,that need to go to the Hell's gate,and in Wolf's rain,they are the wolfs,that are searching to find their own paradise.
Police is also related to both anime,as well as mystery and experiments.

The tone is both are kept more serious. As they are created by the same company, the art styles are comparable with similar colors and quality. While Wolf's Rain takes a more religious approach, Darker
These are some of the best endings you will ever see in anime.
