You've just discovered Kokoro's worst match up in the whole game. She's at a complete disadvantage against Christie. I've argued this in the tier list thread, but people said I was exaggerating... But Kokoro has no tools to reliably deal with Jakeiho at all. What you could theoretically do is the following, although they are VERY risky, and will probably fail, but, she has no better options...
- 66P+K. Since it's a 3 in 1, sometimes it'll hit her out of it.
- 46PP. The second punch is a mid that tracks. It'll come out fairly slow, and is unsafe. Chances are she'll crush the first punch, but, it's useful at a distance.
- Low grab. Chances are very slim that you can land this without getting hit in the face. But if you see a Christie player doing the same move over and over, and you know at which moment they'll go into Jakeiho, you can low grab her out of it.
- Try to focus on mids and lows in general. Moves like 1KK-4K/P/2P can be pretty useful, especially if you delay them a bit. Delaying is always a risk though. You can hit sidestepping opponents when your input is later than they sidestepped, but, you can also get hit for delaying, especially against someone as fast as Christie.
That's all I got...
