Ah, Evans Gambit. The beginning is very reminiscent of some old game trailers and even some old school anime here and there, and that's on purpose. Let me explain: This track is made for a collaboration event with Black Rock Shooter. The characters pictured are: Crimson Weave Alpha (whose design is HEAVILY influenced by BRS), Black Rock Shooter, and the big bad of the BRS franchise, Dead Master. I highly suggest checking out at least the OVA released in 2010, and the first season, which is like 8 episodes. UNFORTUNATELY the newest season is kinda mid, and getting your hands on the BRS game would be pretty difficult as it's a psp exclusive. I've heard pretty good things about the latter.
