thumb|300px|right|Opeining. Darker than Black: After Sunset follows the tale of Contractors, attempts to bring them back into society, and a new antagonist that seeks to destroy them all once more. Due to media leaks, the public has become fully aware of Contractors in everyday life. This has lead many organizations to seek to earn Contractors rights within society once more.
However, this stresses those who have come to hate Contractors for the troubles they bring, and so the Gates are sought once more, in an effort to wipe any Contractor out who they do not deem 'worthy' of life. Once this is revealed, Contractors must seek to help each other, and with an uneasy alliance, they fight to stop this plan from becoming reality.
However, there is another question that lays unanswered, and avoided by all. Its answer may seal the fate of the Contractors, one way or another: Where is the Black Reaper?
