Youko flicks a glance back over her shoulder at the gunfire and - ah. She knows that guy. Presumably, he and his companion know a little more about this species of shen, and they appear to be aiming for their heads, to mixed results. It certainly seems to take care of them after the second shot. Perhaps, then, she should bear that in mind.
She kicks against the chest of the zombie she was tangling with to free her sword, then lops the top off his skull. Indeed, he falls back for a moment, brain split and spilling, body limp as its rotten state should make it, but then another burst of whatever dark energies animate these corpses takes hold and he charges towards her again, faster this time, more than humanly so. It's just as well she's used to that, and this time, her sword removes his head from his neck completely, sending him sprawling into a leaking, stinking headless heap on the ground.
She decides that being quite so close to the horde of zombies when there are guns being used is a little tactically foolish, and flips back to land more conversationally close to Mickey and his friend. "What movie?"
