After her mother taught her the technique to create weapons and tools, Mokkinbādo decided to craft a sword of her own, one that would allow to utilize kenjutsu to its fullest, while still having some power of its own. She then created Hanjiru, at the age of 10, a sword composed of yin chakra and energy. With it, she can manipulate yin for her own purposes, as well as utilize yin in a manner that allows her to sever a person's soul through the added imbalance of the sword's yin. With it, she can also temporarily seal a person's soul, with the yin chakra acting as a basis for covering the yang. She calls this style of her's True Kenjutsu, because she believes that was Kenjutsu's original purpose, beyond the simple cutting and slicing that people do today.
