Bloody Evolution is the name of Dani's store as well as her gang. Although by "gang" I mean they're really only a group of skilled and rambunctious blacksmiths who are an irritation to the town, yet you can't argue with the results of their work.

And yes, the name came from the theme song to RWBY. It sounds awesome and fits her personality. Evolution from the high quality of work they do, and Bloody because Dani's a trigger happy maniac.
