Apparently the position of your sword determines the force that carried the Gatotsu among below is weaker.
- Gatotsu Nishiki: This attack beat down from a top angle. The position of the stroke changes, placing the sword in the same way, only this see above your head, then jump to get over your opponent and then fall giving the usual thrust Gatotsu ...
- Gatotsu Sanshiki: This other technique is for air combat. You use the normal position, only aiming at a target air, then you jump into releasing the lunge.
- Gatotsu Zeroshiki: This is the number 0, raises the top of the body using a small jump that does not require large spaces, namely ... require to be close to your opponent, then you make a small leap backwards for some distance, then become a lunge forward making it very difficult to dodge because of the distance, and has the greatest power of all Gatotsu .
