Kasui lets her entire body simply fall limply to the floor, where, like a serpent, she writhes in sensuously undulatory waves until she upturns her body into a hand-stand and then bounces from hr hands onto her feet again. Spinning in a downward spiral she extends her left leg in a motion that sweeps above the floor like a propeller blade only to raise, on the ball of her foot and still spinning, to her full height where she extends that left leg above her head and holds it there by gripping her foot with one hand.
