Eight Trigrams Palms Revolving Heaven

Eight Trigrams Palms Heavenly Spin This jutsu utilizes the chakra control gained through Gentle Fist training to release a huge amount of chakra from the user's chakra points when struck. The released chakra blocks any possible attack. The user then spins themselves rapidly to parry the attack, both creating a shield of chakra around themselves and tossing away any would-be attackers.
 * Type: Hiden, No rank, Defensive, Short range (0-5m)
 * Users: Hyuga clan

However, the "Hakke Kaiten", as it is also called, is only effective when rotating. Chakra itself is not enough to stop a physical attack, unless it is extremely concentrated, such as when the Nine Tails' chakra enhances Naruto. Since such concentration is impossible with the Hyuga members, they must rotate in order to maximize the deflection. If the rotation stops, they become vulnerable once again, as evidenced by Neji's fight with Kidomaru.
