Jo-Ahn was a Jedi Padawan of the Human species (specifically, female) who was a student at the Jedi academy located on Coruscant concurrently with Roan Novachez. She sometimes participated with Cronah and Cyrus in acts of bullying directed towards fellow students. While she took pleasure in teasing Roan, she tended to be reserved and did not speak much. During her initial year, she authored an advice column for the school's publication, The Padawan Observer, and also participated in the Lightsaber Fencing Tournament. In the same period, she was victorious against Roan in a lightsaber duel.
During Roan's second year at the academy, Jo-Ahn was assigned to the same group as Roan, Cyrus, Cronah, and Greer for a droid construction assignment. The droid, which Roan named M.A.D.S., turned out to be a successful creation. She once again competed in the Lightsaber Fencing Tournament, but this time she was defeated by Gaiana. Though she still occasionally joined Cyrus and Cronah in cyberbullying other students, she avoided probation that year.
In Roan's third year, she was friendly like Cyrus and did not pick on Roan.
