She wields a scythe called "Scythe Machina" (サイスマキナー, Saisu Makinā) as her Volt Weapon, and is a proficient user of the Accel Turn technique, being able to move so quick that she can attack from behind while starting out in front. Her Accel Turn is unique, as she can use Double Accel without the lag between turns.
