No worries! We'll wrap this up ASAP.
I'm sure that you understand the intricacies of this techniques, being a skilled sensei. However, let's reiterate a few things. Kenjutsu is one of my favorite abilities of all times, particularly for close quarter combat. There are two things I would like to point out for this technique. Firstly, would be the range. The range of Kenjutsu or even Taijutsu means too much in a battle. The closer you are to your opponent, the more deadly and swifter the attack is. Secondly, is the type. Although it says offensive, this technique feels much more defensive. Note the rank of this technique = A. Given that it is a wild burst of power before you in a large arc, imagine the lower rank techniques you can stop. As it is a canon technique, I can see this being very useful in battle tests or even in simple fights.
Thus, I'd like you demonstrate it once before we move on. Standing about five meters before you is my clone. Watch his movements closely and utilize this technique as counterattack. First, he will form handseals to release a simple, yet powerful blast of Water towards you, aimed at your chest level. Secondly, he will then run towards you, bringing up his right hand to deliver a punch towards your left shoulder.
Use knowledge of close quarter combat to halt him and demonstrate your mastery over this technique. Remember that your dominant hand is necessary in order to swing a sword with enough power.
