What makes RWBY science fantasy is the intermingling of elements. Technology is a key aspect of the world, their weapons are based on technology, their auras are measured with machines.

Even the pseudo-magic that is dust directly intertwines with technology.

Everything about RWBY is magi-tech, science fantasy incarnate.
