The childlike goddesses serve Taiitsukun and reside at Mount Taikyoku with her. They are also known as Lai Lai. They can take the appearance of floating orbs and can appear when commanded. They have healed Miaka and her warriors when it was necessary, also offering to fix Nuriko's perversion (much to his dismay) and Taiitsukun's face (much to her annoyance).
Their other function is to serve as vessels for the spirits of the dead Celestial Warriors, so that they can fight along side their priestess, in which case they take on the appearance of whomever they are inhabited by, and have all of their powers.
