The series begins in 2006, five years after the "I-Jin" incident detailed in the "Read or Die" OVA. Yomiko Readman (a.k.a. "The Paper", agent of British Library Task Force) has supposedly gone missing, and Nenene Sumiregawa, her former student and best friend, is still in Tokyo after her parents moved to the United States. Nenene has not written a book since Yomiko disappeared, as she has become lonely and frustrated that her sensei has never read her last book, and she feels she can't write again until she hears Yomiko's reaction to the book, so Nenene often disappears for long periods of time searching for Yomiko, and has been periodically doing so ever since her "disappearance".
