Stormblood, yes. The 60-70 questline has Shatotto (or at least a copy of part of her personality) turn up for what I feel like is a plot device excuse to, well, introduce her and what she thinks of Black Magic.
It does have the delightful bit of lore where Shatotto lived and died long before the Mhachi resorted to voidsent summonings, and so Shatotto had no idea why all "modern day" Black Mages use these big hats.
