I just started using Kokoro one or two weeks ago and i could use some help. Any tips?
One thing to note is that because Kokoro isn't someone you free-cancel with too much, someone who knows her strings well will be able to counter you most of the time because she's quite predictable, and rarely does Kokoro put you at a 50/50. And Kokoro has a defense that sucks. Sidestepping's her main weakness, but she also lacks any sort of low crush (9K doesn't count because it's a high and it will never hit ducking lows, and the follow-up P is way too slow). She also has average speed, so watch out for Christie, Kasumi and Pai since they will be able to interrupt your attacks.
Other than that, she's extremely easy to pick up, probably the easiest in the game. Her damage output is insane, she has plenty of one-guess CB setups (you have to choose between a CB, a high launcher, a mid-kick launcher and a reset) and more preferable for aggressive players.
