Commodore Leanna is one of four powerful commodores aboard the sailing fortress known as G-0. Leanna, like the other three, underwent special training from Galaxy Blade to bring out her true potential. Though her caring attitude and extreme intelligence, made it obvious of her potential as a medical expert, capable of treating fatal injuries as if they were mere child's play. Leanne is the Head Nurse aboard G-0 (All medical personnel are classed as nurses aboard G-0). She runs the entirety of medical facilities on the upper decks of G-0.
