He neither took a step back nor did he fall on his ass.  Every strike was met with his own blade, and the smile on his face was a dark, violent thing.  "More," Zhou said.  "More.  MORE!  Give me everything you got!"  Lightning encircled him, swirling around him as if it were a vortex.  It would have less effect on her than it had before, she'd been training, getting more adapted to it.  But of course, it was his natural element, a dangerous and volatile power that could be used for multiple things.<br/><br/>Rather than lash out at her directly, he merely detonated the power encircling him.  A sphere flashed from around him, going out in all directions as pure electrical energies would flash through the area.  The intent wasn't to cause harm, just distract so that his sword could flash out and strike at Natsumi.  While the blow didn't have the pure killing intent behind it, he meant to wound her.
