Gui Fa is one of the seven members of Lord Tensen, as well as a partial ruler of Kotaku. They wore the title of Decorous Monju Koukō (文殊公々, Monju Koukō). They remain androgynous throughout the entire series.
Like the rest of Lord Tensen, Gui Fa is named after a flower. "Gui Fa" (桂花) meaning "sweet osmanthus". Furthermore, Gui Fa's hair is in the shape of the petals from the osmanthus flower.
