So this is a trailer for a movie that would star Nagasawa Nao (HurricaneBlue) and the goth loli Hopper Dopant from W (no typecasting there). Honestly, I think I got what I needed from the trailer itself. It's sexy and violent, it looks like a video game. Why ruin that with what would probably be a bad story that would just take away from this? Just make a music video out of it or something.
