Takeya's devoted DearS, who was found by Takeya after her suspension pod was lost and broke open during transport. Initially, she had no given name, but Takeya dubbed her "Ren" after the first word of her identification number—at which time she "imprinted" upon him. According to DearS law, a slave that chooses a master on her own is seen as having the 'Gift' and is considered sacred. In the DearS language, the word Ren means "zero" thereby making her one of the imperfect "Zero-Numbers," in which was not intended to be revealed to the public. Big-breasted and beautiful, she is a wonder to Takeya and his classmates, but constantly needs to be watched due to her inexperience with human customs and Japanese culture. Ren absorbed the Japanese language in a single night with a pile of textbooks and dictionaries from which Takeya planned to teach her. Her favorite food is melon bread, for which she harbors a ravenous appetite.
