Blood Manipulation: Kanushi

In order to initiate this technique the user has to focus his mind towards the chakra coursing through his heart and blood. As he does this, his heart starts to race faster and more powerfully by the second before a final heartbeat sounds like a audible drum through the air, stirring the grass/dust around the users feet, as the technique is activated. 
This Technique increases the heart rate and blood circulation, passing more nutrients into the vital areas of the body needed to increase ones physical power at the cost of severe drawbacks affecting both body and mind.
Usage of this technique automatically forces the user to lose their sanity the longer it is used. It is also highly dangerous to use prolonged amounts of time due to the body being forced into a state of overdrive, causing organ failure if used without caution. 
In return for these sacrifices the user gains a great amount of physical prowess, increasing their speed and strength by 4 points. 
===Strengths:===
Greatly augments the user's physical performance for a set duration of time.
===Weakness:===
Use of Kanushi causes bloodlust during the 1st round, heightened bloodlust during the 3rd round, and, a berserk state of mind during the 5th round of posts. (click here for more information.) 
This technique can not be used for more than 6 rounds of posts, including the post of activation. 
Use of this jutsu adds a Blood Counter.
