The Tailed Beast Ball was an S-rank ninjutsu that both perfect jinchuriki and tailed beasts could use. It was the tailed beasts' ultimate technique, and one of the two ultimate techniques available to perfect jinchuriki—the other being Tailed Beast Transformation. Lin Chuan could now use both, though the Tailed Beast Ball could only be unleashed while in Tailed Beast Transformation. It was one of Lin Chuan's absolute trump cards.
A tailed beast's chakra consisted of black "Yang" chakra and white "Yin" chakra.
