Kuroten

The is a technique devised by Kumoi Hatake after attaining near perfect mastery over his chakra, and by utilizing this technique, Kumoi is able multiply his abilities by tenfold in it's normal state.

Overview
By acquiring mastery over his chakra control, Kumoi is able to reverse the flow of his chakra, initiating a large spike in power. Since the chakra was not designed to flow in such a way, the body reacts by attempting to force it back, and the pressure created by the two forces is the actual increase in power. By simply changing the direction, Kumoi multiples his body's physical capabilities by tenfold, as the pressure created by the two flows is not as significant as it could be.

However, by increasing the speed of the chakra that is travelling in a reverse manner, the body reacts in response to reset the flow to its natural state, which results in a greater pressure output. In fact, the highest Kumoi has ever increased the speed by was able to increase his abilities by a hundredfold, but that resulted in his near death, only surviving due to a complete chakra transfer.

As noted by previous events, the higher the pressure output, the stronger Kumoi becomes. However, the stronger Kumoi becomes, the more physical strain his body undergoes. Thus, Kumoi doesn't often go past the times twenty multiplier, as any higher and he risks serious consequences.
