The song is This is War by 30 Seconds to Mars. In my opinion this AMV defines the story of Reborn! and its epicness very well in its duration. Awesome song, awesome video, so in my book it definitely gets a 7 Star Rating!
Hope you enjoyed it as much as I did, all credit goes the maker of the AMV, it seems that it has won several otaku festivals and conventions which it very well deserves to. This is probably the shortest post I have made so far, besides the Technorati one. Anyways I wont make you waste more time, Danny out!
