This is a new web series by Rooster Teeth Productions (made the Red Vs. Blue web series). I think it looks pretty good I don't know if it would be classed as 'anime' as I don't personally watch it but this does actually look quite interesting.
They are releasing 4 trailers for each of the letters (Red White Black Yellow) So far only Red and White have been released but I'll update the thread with the other two once they are released
I also really like the music to the trailers
