First time I watched darker than black I was addicted to it watch it all in no time xD left it as it was and thought since alot the characters die ect that was the ending to the series and now I seen 2nd season of darker than black and go OMG! buy both seasons off the bat, currently on episode 6 of the second season. Love all the characters in the 2nd season its what got me into anime as a kid was how detailed and realistic characters were and the story.
Now I'm wondering as I watch rest the episodes will there be a season 3 in the works? mostly because I never fully looked in the spoiler department but do know it has big cliffhanger and I'm like oh noo! not like this! thought season one has good ending but if season 2 leaves it open and unanswered questions arise why make another season just leave it open??? believe like every other show that the creators leave it open so IF they say,
"hmm lets continue the series" then they have valued point make plausible ideas to a season 3 start off from since they made the fans on the edge there seats wanting more its very suitable make more episodes. They would of left it at season one ending if the creator did not want make more just doesn't make alot sense, time will tell..
