Personality: If you hadn't guessed by her looks already, Candy, just like what they tell everyone, is bright, outgoing, happy-go-lucky, mischievous... Well, anything but mature, that is, unfortunately enough for her.
Candy likes to talk before she thinks, and her hyper personality, along with her naughtiness, has punished her in several different ways. No one has ever seen her sad, let alone crying in a corner; she has been a cheerful girl for as long as anyone can remember, and there's certainly no doubt about that; she was born with her personality.*
However, she is a bit over-reactive and too stubborn sometimes, and has occasionally done some things without meaning to during her training sessions, promptly making her fail, thanks to her bounciness. Candy tries not to repeat that mistake, but it does happen once in a while - and she could be the one to ruin her mission and career if that happens again, much to her dismay.
