Above is the short trailer for the next season of BONES' anime Darker than Black, entitled "Darker than Black: Ryuusei no Gemini". It's set to broadcast in October, and will feature the characters Hei and Yin as they encounter Russian loli Suo Pavlichenko, two years after the events of the anime. I don't know which character is in the mask getup, but I'm reasonably sure it's not the loli.

If you haven't guessed yet, I don't know much about Darker than Black. My extensive research shows that their "Contractor" characters need to do weird things like break fingers and eat flowers whenever they do things. This means that Darker than Black must be a slice-of-life show about people with Obsessive-Compulsive Disorder and superpowers. Incidentally, there is also a Darker than Black manga featured in Young GANGAN magazine, which takes place one year after the anime events. This means that if you read Young GANGAN, you will have three years worth of Darker than Black. An incredible deal!

A different, longer trailer for the show can be found at the official website (just click the button marked "1M"). There are also wallpapers available, featuring an ever-so-cliche sniper rifle-and-girl combination.
