Even if Okita isn't ZZ, she seems to have some connection to her. The gear, plus the fact she has the Passive Existence Outside the Domain skill, something previously exclusive to Foreigner Servants. And considering they like to highlight that the Mysterious Heroine characters come from the "Servant Universe", ZZ would likely come from there too, meaning she isn't from our domain.

It could be that ZZ is just screwing with Okita's Saint Graph much like Apollo did with Paris and Orion with Artemis.
