Tbh I didn't name them after characters in other FF games (I considered naming the thief Locke and the black mage Vivi, but decided against it. Also I thought of Ayaka for the white mage, because FFBE), so I went with Street Fighter characters bc idk

Warrior - Ken (bc he's blonde and Ryu has black hair idk)
Thief - Ibuki
White and Black Mages - Rose and Bison (bc Soul Power and Psycho Power idk)
