True Sword: Armageddon

Taking her sword out, she runs the yang part of chakra through the sword in order for it to combine with the sword's yin energy. The result is the creation of the yin-yang, which she then concentrates at the point of her sword. As the yin-yang chakra conjugates, a small ball of solid energy is formed, growing larger as the yin-yang energy from the surrounding area. Once the yin-yang gathers to the amount that she wants, she releases the "ball" of yin-yang energy. The end result is destruction that could be unrivaled by any other technique. The yin-yang literally and figuratively erases everything in it's path. At its most powerful, it is capable of destroying a village, effectively erasing its existence from the planet. However, by transferring her chakra to the sword, she also permanently removes part of her chakra, weakening her greatly and diminishing the her already relatively small chakra reserves. During the duration of this attack, she is also vulnerable to enemy attacks because all of her focus is on creating the ball of yin-yang energy.
