Deadman Wonderland: Complete Series

"This mind-bending release from the psych-horror anime series Deadman Wonderland includes all 12 episodes of the show, following the story of a high school boy who is unjustly jailed for the murder of his class in a prison system that fits him with a collar constantly injecting him with poison. The poison can be neutralized if he can take regular doses of the antidote often enough, though these can only be obtained through prison work."
