The sparks you saw is supposedly excess energy generated by her beast factor like Michiru's. Because she and Michiru were originally humans before turned into beastmen thanks to exposure to beast factor reagent via. botched blood transfusion, they were not only gained beastmen' animal shapeshifting abilities, but also unknown powers seemingly exclusive to them. The sparks you saw happened to be one of such powers I think.
