This style is really simple, and although many people probably know it, I still find it to be an effective style. Because of the fact that it is simple, you can change it around and mold it to your own strategy. The Main style goes as follows: Hold all (hit C), Relax knees and hips (Relaxing knees and hips makes your person crouch faster), Contract Pecs, Raise Arms, Space - Once you are here it is pretty straightforward. This is a good defensive position, and it allows you to block a variety of attacks. At this point you have a good setup to use your Toribashian in any way you want for defense or attack. I call this setup "Dual Defender."
My favorite way to finish the enemy is as follows: From "Dual Defender" - Space - Space - Extend Left Hip (The reason to extend only one hip is because if you do both, you jump to fast and miss the enemy with your swords. However, if your enemy is above you, Extending both is a good idea.) Once you Extend your hip and hit space again, you should lunge at their chest with your swords. Against Uke, you Decapitate him and remove his arms at the same time, and the fall away to a safe distance. Against human enemies, the effect varies, but if you hit in the same general spot, their arms will shoot to the sides, where they cannot hit you. (I always hate disembodied arms slicing me.) After you lunge, go from there to find the best course of action. I call this move "Ballista Lunge." If you manage to have the time to hit space the many times before you do it, it is very effective. Luckily, even if you do not, you still have the advantage of being in a defensive position.
The two counters to this move are: If someone lays on their back and kicks your arms from underneath. This sucks because then you can't do anything. However, I have only had that done once, it is difficult to pull off I assume. The other is very simple, and all it is is contracting pecs. The persons swords will reach you before yours will reach them, and then your dead. Most of the time however, the enemy will try something more complicated. The only time this happens is when you use this move over and over, then the people in the room start to realize the fact that you never do anything else, so they do that simple move. The fix for that is just mixing this up with something else. Happy Hunting!
