Have you met all the Moogles of each class, and read their personalities in the Historical Personae? It's cute to read all the descriptions.

Which one would best represent your own personality? I'm Class Three Moogle, easily. '

Detached and honestly quite depressing. Ze is rather shy, rarely speaking unless spoken to,. Once you get to know hir, however, ze wil l transform into an ever-flowing fountain of sarcasm and negativity. Still, hir persistent pessimism is just part of hir charm.'

Haha I presume Ze and Hir are a form of Moogle, genderless pronouns.
