Tao Fa, also known as Great Sage Ratna (ラトナ大聖, Ratna Taisei), was a member of Lord Tensen, as well as one of the rulers of Kotaku. She maintains the female gender throughout the series.
Like the rest of Lord Tensen, Tao Fa is named after a flower. "Tao Fa" (桃花) meaning "peach blossom". Furthermore, Tao Fa's hair is in the shape of the petals from the peach blossom flower.
