The oldest (in the anime) and the wisest (indisputable for both anime and manga) of the senshi, "Pu", as Chibiusa calls her, keeps her eye upon the portal of time, and the activities of time. She is a solitary figure, and rarely leaves her post at the portal of time, but she is no less fiercely loyal to the Princess (both Princesses) than any of the other senshi, and loves Small-Lady with the same protective love a mother would have.
