Alright. Slightly bad wording, but good performance. One thing to note however, not every Gentle Fist technique closes the opponent's chakra system. Not as far as I know atleast. This technique certainly doesn't. Make sure to read the technique's description carefully to understand it's effects and process. Don't add any extra stuff that is not in the technique, nor do you remove anything. Usually, it will be a mis-use of said technique, you would even lose a match for that.
The technique only paralyzes the target, due to the shock their internal organs took. There chakra pathway is not closed.
That's the last B rank technique, but before we move onto A ranks I want to make sure you're actually getting this. So for a quick recap, choose 3 B rank techniques and explain a scenerio in which you would use them, or a possible combination with each one.
