I apologize for the late reply, I have been extremely busy.
After listening to your explanation, I kick off by taking a stance where I position my right leg forward, with my left leg backwards and my left feet turned sideways so that my right feet is vertical on it. Simultaneously I position my upper body as follows; left arm positioned parallel to my kidney with my left hand holding the sheath of the sword. While my right arm bent towards my left with my right hand holding the grip of the sword. I then do a swift move releasing the Sword from it's sheath delivering an upward diagonal hit that extends to the right aiming for the opponent's kidney, left lung, heart, and shoulder. I then drop the sheath to the ground and hold the bottom of the sword's grip with my left hand with my right hand still up and deliver a straight slash downwards, that starts at the opponent's head and ends by slashing his groin area. I finish off by taking my left hand off the grip of the sword, and swing the sword in a circular manner over my head and deliver a slash that is aimed to cut off the opponent's head.
Questions:
• Is this technique lethal despite it's rank?, like if I aimed it towards vital organs would it kill the opponent?, or is it only mere cuts cuz it has a low rank?
• The total rank of the slashes I make are C rank, correct? can I make only one slash that is a C Rank?
