Nice. Always gets more consistent after the first time so you probably don't have long before you start getting some tries at stage 6.
If you haven't yet I'd advise you to practice Okina with low resources until you have relatively okay odds of surviving her with at least two or three lives. More than a couple of my LNBs I've only gotten because of good final boss performance after everything else going horribly, so it's actually not bad to depend on.
