Strategy
Neutral
Because Kyoko lacks good long-range options for neutral, your best bet is to try and build meter by whiffing your air chains if your opponent decides to back off. If you can successfully goad them into coming to you, you can intercept their approach by jumping toward them with your fantastic aerial buttons and try to establish offense.
Offense
Kyoko's okizeme starts with landing EX Sazanka. From here, you want to dash, then dash jump into j.HK. This sets up an ambiguous left-right mixup, with the side you end up on depending on the timing of your dash jump and your button press. You can also time the j.HK to whiff, or forego the j.HK altogether, to instead add an empty low option into the mixup. Since the resulting combo you land from this generates a fair amount of meter, you can loop this okizeme setup for a pretty decent amount of time, cashing out a ton of damage in the process.
Defense
If you find yourself on the defensive, you have some solid guard cancel options and EX Ominaeshi, so don't forget to use those if you need some breathing room. Remember that Kyoko is very highly dependent on meter to really make the best of her tools, so make sure you stay on top of your resource management.
