Piercing Fang is a taijutsu in which the user rushes at the target at enormous speed and slams into it with the entire body. During the movement he spins rapidly, which allows him to literally bore through even stone. Because of the high speed, the trajectory turns out almost straight, so it is important to calculate the opponent's movement in advance so that the blow lands accurately. Unlike the Fang of the Piercing Fang, this technique is performed alone, and additional training is required to enhance its power.
