This move is first used against his brother Shūsuke in their tie-break at the U-17 Camp. This shot is an improved version of the Twist Spin Shot, where the posture is the same as the Twist Spin, except for the form to use a Two-Handed Forehand instead of a one-handed one.
The Double Twist Spin Shot causes little to no strain on the arm. However, because it's a spin shot and not a power shot, the amount of spin still remains the same from the original Twist Spin Shot.
