Jack Russell initially encounters her on his way to the Vareth Institute when the two accidentally bump into each other. Leona apologizes and asks if he has seen her glasses, which she fails to realize are still on her head (a fact that makes her blush heavily upon realization). She then thanks Jack for his help and runs off before she is late to class, although she accidentally trips and is hit by both the nearby wall and her airborne book.
Leona is a student of the Vareth Magic Institute and Genius' younger sister. While working hard under Cecil, she managed to decipher some magic documents left by the original president of the institute. She is the only one who can read the manuscript. A very shy and timid girl, she always has a worried look on her face.
Leona is a surprisingly useful mage, despite not being a Guild Leader. Her true strength lies in the combined power of her unusually high Attack power, rivaling that of even Clarence and Gerald, along with the ability to bypass the enemies' guard. Along with the infinite range of her spells, Leona can be a force to be reckoned with on the battlefield.
Her primary weakness is the amount of time it takes to charge her attacks. Unlike other mages, Leona has a considerable starting lag to all of her spells. Because of this, a weaker enemy may have been destroyed or the spell may be executed when the foe is knocked down or counterattacking, rendering her attack useless and forcing her to wait again before executing another attack. Additionally, her average HP and Defense can endanger her at times, but because of the infinite range of her spells, she likely won't approach the frontlines at any point, unless placed in a Link.
