Indigo

Opening the Sixth Gate, Kaoru unleashes a sudden constant stream on indigo coloured chakra, hence the name. He then proceeds to assault his opponent with a flurry of high speed, powerful punches. As the technique intensified, Kaoru begins striking his opponent with his fingertips, targeting the opponent's chakra pathway system. The attack does not merely block chakra flow, it ruptures tenketsu points, seriously injuring enemies. The sheer power of the punches can and will kill the target after two blows. The immense speed of the technique means that it is unavoidable by means of reflexes, as even the best reflexes can't keep up with the Eight Gates enhanced pace.

Drawbacks
As Kaoru strikes with his fingertips, the intense power needed to generate penetrative jabs are capable of shattering his fingertips completely. The technique also tires Kaoru significantly, and he requires protection while he recharges.
