Nenene Sumiregawa (菫川ねねね Sumiregawa Nenene), a.k.a. 'Sensei,' Nene-neesan: A prodigy novelist in her high school years, featured in the Read or Die manga and novels as a teenage friend of the older Yomiko Readman. Due to the disappearance of Yomiko, she has become very self-sufficient but unfortunately wistful and bitter at times. She remained in Japan, despite her parents' wishes, in order to housekeep and tend to Yomiko's personal effects until her (assumed) return. She is often threatened or kidnapped by crazed fans, literary rivals, and malevolent organizations; these incidents serve as important ROD plot mechanisms. For example, the Paper Sisters first appear in the ROD TV series when Nenene's publishers hire them to escort Nenene during a booksigning in Hong Kong.
