>>49049927i'm pretty sure its either plus 1 or 2 you can backdash sure, provided you aren't in the corner. If you do backdash though her 5 h catches you since it moves her forward and stays active for about 5 years. My best suggestion against botan is to look if she tosses out 5m in neutral and slap her for it with either a long counter poke or a jump in since it stays active for so damn long.
of course that's easier said then done when she has the best anti air normal hands down.
