Definitely easier to do the normal way. I used Mitsurigi as my char and Xianghua as opponent.
Go into training, then option. Go to Freestyle Settings > Guard Impact > Rebel.
Simply slash using X, she'll repel, then you press forward and A.
Now press X again, wait for repel, f+A.
It's very easy to do, timing isn't even essential between these 2 you'll get the rhythm down in no time. Same as Tekkenite's solution but dunno if Cerv vs Sophitia is as easy as Mitsu vs Xianghua.
