Jirō can, thanks to his God-given wrists, freely control where he will hit a volley from any positions with just a snap of his wrist, regardless of the irregularity of the position he is in at the time and where the opponent hits the ball to, provided he's at the net. More impressively, no matter what position he is in, Jirō can hit a volley to any direction he wants. Due to this, it is nearly impossible to predict the directions of his shots. Inui states that his volleying technique reminded him of John McEnroe, a former real-life professional tennis player.
