[@Capt0blivious] It works the other way around. Titles don't enable a character to grow, a character's growth allows them to take titles. so a title can be related to anything that a particular character is likely to learn, be taught, or acquire over the course of the game.

For example, if Yuu teaches another hero archery, they have the option to take the title [i]archer[/i]. They'll still have learned the skills even if they don't, but spending Prestige indicates that they've really taken it to heart. (Titles don't have to be long.)
