Biography
Not much is known about the Untailed, as it was believed to be a folk-tale until Yoshirou awoke it. It's implied that the Untailed wields genjutsu, as Harune fell under a spell when she looked too long at its form. The Untailed is also hosting a vast amount of chakra, as Kakashi exclaims that Yoshirou will never be able to control it.

Appearance
The true form of the Untailed has never been seen, but the beginning stages of it have manifested in Yoshirou. It's chakra surfaces as an iridescent white-blue shade and large wings sprout from the jinchuriki.
