Warrior: Jules - Male version of my name
Thief: Damont - I had the name Damon picked out, but then I thought of the final case of the first Phoenix Wright game, and was like "NOPE!", so I added the "t".
White Mage: Mina - Just a nice girl's name I like to use. ^^
Black Mage: Zeke - Just a random guy's name that popped into my head.
