Fina

Known as "Lady Fina" to the other DearS. Her official position is that of the "Watcher", and she seems to be the leader of the DearS colony; even Rubi bows to her. She does not awaken until volume 5 of the manga, and seems to support Takeya taking Ren in as his slave. In fact, she immediately orders Rubi to stop trying to recapture Ren.
