both of those are amazing and in my top 5 favorites another one you could check out would be Shiki also even though i havent seen it yet i hear that Btooom is kinda like Mirai Nikki since its like a survival game

I Recommend Deadman Wonderland and Btooom, i wasn't sure about Deadman Wonderland because it didn't really look all that good but its actually an pretty good show :) Btooom is really good aswell. They are both survival games like Mirai Nikki so yeah, have fun watching :)

Thanks guys :)
