- "My, my, my. There are two presences. Only one of ’em is all fired up, though. And that darkness—it’s special, absorbing all signs of people, sounds, even movements of the air! He could be standing right in front of you, and you’d never even know it till he stabbed you."

The ability to generate and manipulate darkness for a variety of effects. Most common use is complete concealment visually from others despite the ability to pierce darkness with visual powers or not need much light to see such as night vision. The location of the individual along with their voice or any other sound is completely concealed.
D displays this ability many times through out the series. Some shining moments was when he fought Toma. Though The Night seems to be a special kind of darkness manipulation D's power is darker than it and over powers it easy. D also seems to use a high level of this every time he uses stealth moving with out causing even the slightest amount of vibrational disturbance even over the surface of water, and leaving no foot steps even in the snow. In the movie Bloodlust he uses it to over power Carmilla.
The Gilzen Commission is assaulted by Duke Gilzen under the cover of darkness he manipulates in the brightness of the day time. Under a kind of darkness form that can't be perceived, turns all the Mountain Folk in flight. The group notice they all have the power to walk in the day light despite being Noble. In the mist of their astonishment, Lourié is grabbed temporarily by the Duke who has him drink some sort of concoction. This drink turns him into a living corpse instantly.
It seems to be a well known fact among vampire hunters, that whether its through mystical or skillful means, hunters are required to get the better of darkness, melding with it and concealing themselves becoming one with the world around them. Those who can not, can no longer live as hunters as described by JJ.
