Clearer and longer version of the preview on this site http://recochoku.jp/song/S1000794287/?ds=A1001087237 I love what I'm hearing. I already like it more than the current Opening for Akame ga Kill. Choir + guitar + violin + Mayama = \m/
I'm waiting to see if it appears on CDJapan to start counting money and order it with Hatateki (I haven't decided which version of that I want either...)
My first time hearing about Akame ga Kill was because of Mayama, but after that I started seeing it on all the anime sites I visit. I guess it was a matter of not paying attention.
I liked the first 13 episodes. If they keep it up for the next ones it has the potential to be quite popular (for international fans at least)
