Ayane 4P is a godsend against Pai. All her strings second hits are like... highs rofl. Where as Sarah has mid variants in her strings, harder to crush her than it is Pai. Not to mention Sarah's stance cancels... flamingo has that weird invul dodge thing... yep. Pai is much easier than Sarah. Pai is realy easy to high crush, Sarah it's risky business. She has an answer to everything.
Against Pai, just turn your fucking PS3 off.
