How do the titles work in Tales of Vesperia for the Xbox 360?

I don't expect much of an answer for this because of how recent the game is but i suppose that someone has a clue and i intend to find out! I think the titles may have something to do with the stat growth for the characters as it did in ToS (Tales of Symphonia) but i am not quite sure and i would appreciate it if someone could help me. Please?
