Tenketsu Blocking Strikes

A taijutsu technique that allows the user to disable an opponent by performing a two-fingered thrust at the opponent's Tenketsu. By doing so, the user can manipulate the flow of chakra within their opponent, similar the the Gentle Fist fighting style. Shira can unblock his opponents' tenketsu, with a single impact with his fist.

While seemingly not hampering the opponent in any other way, it seems to prevent the opponent from initiating the surge of chakra when the Eight Gates are opened.

Trivia

 * Accurately targeting the tenketsu is normally a near-impossible feat for one without the Byakugan. This shows very advanced aim and physiology knowledge on Shira's part.
