Murasame changes the way his chakra flows, allowing him to greatly enhance his speed, significantly decreasing his opponent's opportunities to react. By flowing chakra through his heart, Murasame can increase its beating, increasing his chakra flow, and even further increase his speed. At his maximum speed, Murasame can confuse his opponents with afterimages created from his high velocity movement.
