Mind of Hachiman

This technique allows the user to flow ki to their mind to enhance their combat instincts. When they do so they become able to instantly understand how an opponent thinks and fight. This makes it very easy for users of this technique to predict their opponent's next move. So much so that this technique has been given the secondary name of: Combat Clairvoyance. Understanding their opponent makes it very easy to spot an opponent's weaknesses and exploit them. This technique isn't supposed to be used all the time, but every so often or in an emergency. This is because the technique can be very taxing on one's mind and if it is used too much or too often it can cause migraines.
