She is another member of underground organization ITEM.
Her power is the AIM Stalker. She can detect and memorize the AIM of any esper on earth. She is like radar for Mugino so she can calculate the trajectory of her beams.
She is a Level 4 and could have possibly become a Level 5, but she suffers brain damage from fighting Kakine Teitoku that prevents the use of her esper powers.
