Gentle Step Twin Lion Fists

A high-level secret Gentle Fist technique taught only to the main branch of the Hyūga clan. The user changes the shape of chakra released from both hands into large lion-shaped shrouds. Doing so greatly increases range and destructive power. The lion heads drain the chakra network of those they touch. It is an extremely difficult ability to learn, as the slightest mistake in chakra control will lead to failure, meaning it is a feat requiring the Byakugan. This technique can be used in conjunction with the Eight Trigrams Sixty-Four Palms.

Development
In the anime, it is shown that during some time in Part II after learning from Ino of Naruto's new technique, Hinata trained with Neji to develop her own. Expelling chakra form the tenketsu is an innate ability exclusive to the Hyūga, and after using precise chakra control, Hinata was able to shape the chakra around her fists in the form of blue dog-lions, as witnessed by both Neji and Hanabi.
