The purpose of the art is to make objects grow larger. Ryōbi performs the technique correctly, but with no way to specify the amount of growth, her breasts expand to Z-cups, resting on the floor and requiring two arms to lift just one. This technique can be undone as shown when Ryōbi was forced her to undo the technique and revert her breasts back to their original size.
