On Ji is a cute schoolgirl at the Fire Nation School, and thus is one of the lucky Fire Nation children. Like all the other kids in this school she grew up in a nice Fire Nation island, away from war and poverty. Her parents think On Ji's education is very important. They hope that if she does well enough she might get the chance to attend a good university possibly on the capital island, where she could meet a nice Fire Nation Royal and make the perfect Fire Nation wife. However, she began attending a high school is Warwick and made friends with several alien children.
