I don't wanna spoil too much of her story but she's born into a lower (often seen as inferior) class/race--however she is the strongest member of the clan and potentially a contender to be the strongest of her race, which is unheard of... She lives in a community where status is achieved through physical strength, and for someone who is "inferior" to be that strong is unheard of.
In many cases I draw her super serious but she's actually a total goofball and she has a competitive nature, but when she gets he game face on she sobers up fast.
