Soru or Shave :

The Soru allows the users to move at extremely high speeds in order to avoid attacks, as well as to attack at higher speeds and with greater power. It was revealed that the principle of this move was to kick off the ground at least ten times in the blink of an eye.

Apart from these there is also a 7th one which is secret even in Navy and World Government.

Rokuogan or Six King Gun :

The Rokuogan is the secret and ultimate attack of the Rokushiki style.

Only those who have absolute mastery of the other six skills can have access to this seventh skill.

The user places both their fists right in front of the target to focus their physical strength to launch a devastating shock wave in a forward direction. The burst is a reminiscence to that released by an Impact or Reject Dial, capable of bypassing the defenses of a rubber human such as Monkey D. Luffy, who is immune to blunt strikes under normal circ.u.mstances, and causes massive internal injuries.
