This particular moment in the trailer is when a Beowolf basically gets shot point blank with one of the cross-magazine rounds. I think the red is part of the muzzle flash from Crescent Rose.

One of the unusual things about this particular sequence is the behavior of her cape, which almost seems to blend in with the blackness. That could be significant or that could just be how the animation rendered.

Another unusual thing is that there are actually two muzzle flash colors coming out of CR. There's a white one that you see right as she shoots the Beowolf, and then a black one that forms afterwards. The movement of the black muzzle flash is actually kinda wierd. After forming, it moves backwards instead of forwards. It goes back, sorta envelopes Ruby's body, then drifts off forward and dissipates.
