While Aya is spinning and drinking, Kazuma is readying his next move. He readies his Gantou with both hands above his head, and starts emanating Reiatsu from his forearms, running up the length of the blade. This quickly starts a massive air current as the rock starts sucking up the energy, creating a vaccuum of Reishi that forces movement. It seems to wrap around the blade like a tornado.
"Senkou Fuuretsujin!" Kazuma cries out as he brings the blade down, and sends the swirling current barrelling towards Aya.
