Nenene Sumiregawa

A prodigy novelist in her high school years usually referred to as sensei and originally featured in the Read or Die manga as a teenage friend of the older Yomiko. She is often frustrated with Yomiko039s obsession with books and later the Paper Sisters when they move into her home and chides her for being absentminded leaving postits in her room. Due to Yomiko039s disappearance she has become very selfsufficient but unfortunately wistful and bitter at times. She remained in Japan despite her parents039 wishes in order to housekeep and tend to Yomiko039s personal effects until her presumed return. Along with two other characters within the series many fans argue Nenene039s dedication to Yomiko borders on the romantic and the series has a strong yuri fandom. Source: Wikipedia
