Darker Than Black DVDs will include a special side story for every second DVD release. This is good news because it’ll explain the gap between the first and second season. There’s a short PV shown at their main site. It’s pretty cool and the second season is one of the good animes airing this season. Always nice to see the Darker Than Black world being expanded on. If you haven’t watched it before, it can be compared to X-men in a way. People with super powers known as contractors although that’s pretty much all they have in common. Check it out though, if you didn’t watch DTB, maybe this PV will convince you to.
