ok...*starts swinging the blade upwards at the tree using my other hand to push the back of the blade*well....
i geuss..
the hiten mitsurugi ryu rauyozen...
this used with your sword alone....
its going to be an upwards swing..
but you need to learn how to use the other hand to increase speed and strenght of the swing....
so go to that tree and practice swinging your blade with your other hand pushing the back of the blade upwards increasing the speed and strenght.
