Firefly, is a shy, curious and observant young lady who is eager for new experiences because of her fleeting life-span. She is currently in Penacony as an area guide and stage performer for the Iris Family, and may also be because of a secret mission brought out by Elio. As Sam, she is cold, apathetic and reserved, due to the mech armor she transforms into changing anyone's personality to whoever pilots it. She keeps it a secret that she is this individual.
