Leaf is a Runner who works alongside Mercury and Drake. A skilled combatant, she teaches new Runners, like Faith, how in hand-to-hand combat. She is noted for using her environment against her opponent and tries to instill this into her students.
During the mishap involving Silvine Security Systems and Erika Connors, Leaf harbored her father, Abraham Connors, in exchange for Faith doing some runs for her in the future. However, Silvine Security would later find them and attempt to capture Abraham. Managing to defeat the security personnel, Leaf took Connors to stay with a friend in Old Town while she returned to consult with Mercury and Faith over what to do about the security firm.
