Synopsis : I not found it.
This anime remind me about Black Rock Shooter OVA, It's already released on 24 July 2010. So, last year we get OVA and now we get TV series. This anime is based on Hatsune Miku's song, Black Rock Shooter
This is one of songs that have many fans. Many fans like this song.
Back to anime, the anime will release on 3 Feb 2012. Kind long times to wait. The singer for ending is supercell. Supercell have many superb songs. Although I'm not their fan, but I know some song from them.
So, stay tune and watch the trailer again and again
