She is a Level 4 Teleporter with her ability, Move Point (座標移動, Zahyou Idou, lit. "Move Target"). It's a more powerful version of teleportation that can teleport any object to the user's desired destination without the use of physical contact (long-distance teleportation). She has a maximum range of 800 m and can teleport objects with a mass up to 4520 kg, though the trainers told her that she'll damage her body if she moves anything more than 1000kg.
