Well that's Nu. She's dumb. You just gotta deal with it.
You just have to be more on point against her, same idea here though. Just push her to the corner and keep her there. She can shoot a sword out when she jump back barriers, but you can also run up and DP her. RISKY though, make sure you have 50% meter to rapid it.
Corner game is still the way to go. Problem is, she can just 5d then dash away, jump and air dash away, block until a hole appears in your pressure and mash dash, counter assault, jump back barrier in the corner and shoot a sword down, etc etc etc.
