She should be the banner after Tactics.

There's 2 banners in between hers and the Tactics banner. She originally came out 36 days after the Tactics banner in JP, but we've been getting banners much faster than anticipated so I'm not sure when she'll come out. I would guess she comes out in about 3 weeks.

after FFT, kitone -> miranda -> lucia
late May or early June

GL approximately 4 months behind JP, so I'd say early June

I think Miranda will come next before her
