Sephiroth's eyebrows raised slightly. So the Protect spell could be nullified with enough of a battering... That could be useful.
The maelstrom knocked Sephiroth backwards a few feet, the first attack to actually hurt him so far in the entire tournament. He shook himself, smoking very slightly, feeling a charge build up around his body and clothing.
Hmm...
Kefka had made no attempt to dodge the first strike, relying on his Protect shield. So there was no reason for him to dodge this either; he would assume Sephiroth was being foolish by trying the same attack twice...
Sephiroth flitted forwards, raising Masamune and slicing it in a wide arc across the shield; water droplets flicked from the end of the blade. Raising his right, empty, hand, Sephiroth shook his fingers, feeling the residual charge from the Thundara attack build up in his palm.
Then, as Masamune moved, Sephiroth placed his hand to the flat of the blade, sending Kefka's electric attack right back at him.
