Uhh... Well, without trying to spoil the game (she changes from the beginning to the end) I'm gonna tell you how she is at the beginning, I guess. Don't wanna spoil the story cause it's actually pretty good. Anyways, she's pretty serious and is just focused on finding the Right Eye of the World, the other gem required to resurrect the creator, Jubileus, but she is ςėχу and carefree at times.
