Shani/Kiara is the youngest of the Priderock, Chaka, her brother is 1 year older than her, and all her friends are a few months older than her. In the fanfic, Shani's personality it's equal to Simba's when he was a cub, she's curious, disobedient, astute and when needed she can be very brave, especially to protect her family and her friends. Shani's self-conflict in the fanfic, it's about living in the shadow of her older brother Chaka, that is irresponsible and lazy, but Simba and the pride thinks that just because Shani is young and "weak", she is incapable to do anything great, and treats her like a baby, something that she hates.
Because of her father's doubts on her potential, Shani always gave the best of her for everything, she learned all her lessons, she was responsible with her duties, and she practiced her hunting skills everyday, but somehow every time she has the chance to show what she is capable of, something goes wrong, like... when the savannah catch fire right in the day of her hunting test...
