Horrible pun, I know. From left to right: Fayth of Valefor, Fayth of Ifrit, Fayth of Bahamut, Fayth of Shiva, Fayth of Ixion.
Since I don't own an Ultimania guide, my sketches (taken directly from the game) can be a bit inaccurate. Bear with me. And enjoy the cuteness.
Am I the only one here thinking that Fayth of Shiva is as beautiful as her Aeon form? (...Am I the only one obsessed with people with scarfs on their mouths? Yes.)
