A lieutenant in the Japanese Comerican esper team Liberty Bell, Mary avails her telekinesis alongside her partner Ken to perform the same kind of police work that B.A.B.E.L. does in Japan but on an international scale. In spite of engaging a devious and dubious device for appraising Kaoru's powers along with those of her teammates, Mary is also found to be a potent ally as she demonstrates when she and Kaoru combine their telekinesis to subdue the fleeing Mute and Lige.
