I am a former Nu player cause fights can just be to dang easy. This match begins with a guess and ends with someones death. Just starting out a Nu player will most likely HJ back dash and use j2D. Then from there they'll start with with 5D-2D crescent saber zone out. Then if they have enough space they'll throw out in between 5D and 6D swords to catch air dashing in. The best way I use to get in is to either know the pulsar spacing and predict when they'll approach then ID. The other is to get out of 5D range, Some Nu's will throw out 4D to catch you with a sword. As soon as you see the animation run at her like a mad man and 5B her into standard combo. Then from there try to keep in her face and apply good pressure strings, high low game, be careful if you use dead spike cause she can back dash outta that if they have good reaction. This has to be one of the most annoying matches to fight, next to Kune/Nu vs Tager.
Btw I main Ragna now
