Kim was a previous member of Tempus High School, the school the main cast goes. However, she had to transfer schools because her dad got relocated. She is now in the Battle Club of one of the rivaling schools.

She is very motivated to getting better, never satisfied with being second best. She's a natural leader, upbeat, and likes to keep people motivated. She's very genuine and fun-loving but can get a little bit aggressive when things aren't going her way or how she planned for it. Character starts out as supporting but ends up being a minor character towards the end of the first season.
