Instructions
Wait for an opening when your opponent isn't directly attacking you. Such a moment might be when he is charging or if he was knocked back or dizzy.
Hold down the "Triangle" button. You will begin to store energy.
Continue charging up until your Chakra gauge is completely filled. This may take a few attempts, depending on who you are facing. Certain opponents will not sit around and wait for you to gather Chakra.
Perform a special attack to activate the Chakra you have stored. For example, to perform the "Naruto Uzumaki Barrage" attack, hold down the "Guard" button and press the "O" button.
