Sumiregawa, Nenene

菫川ねねね

A prodigy novelist during her high school years, she is usually called sensei and first appeared in the Read or Die manga as a teenage friend of the older Yomiko. She is often frustrated by Yomiko's obsession with books—and later by the Paper Sisters after they move into her home—and scolds her for being absentminded and leaving post-its in her room. Because of Yomiko's disappearance, she has become very self-sufficient, though unfortunately wistful and bitter at times. She stayed in Japan, against her parents' wishes, to housekeep and look after Yomiko's personal effects until her (presumed) return. Along with two other characters in the series, many fans argue that Nenene's dedication to Yomiko borders on the romantic, and the series has a strong yuri fandom.
