My advice for you is to improvise, just remember up-medium and up-strong, that's how I play my game as Nanaya, my strategy works wonders against Satsuki.
My strategy would be this : Down-Strong, Down-Medium, a few 5a, then a 5C and just do the jb, jc loop twice while dashing to the other side of the screen and throw them the other way after you do it a few times.
^ Combo sucks crap against the CPU Nero though. I freaking hate that guy, whether he's a CPU or a Human, damn jC..I got raped last time I went against him.
Btw, are there any tournaments online?
