Yomiko Readman can turn a scrap of paper into a throwing blade or a sheet tough enough to stop a bullet, a power that makes her the top field agent for the British Library's Special Operations Division, even though she'd rather spend the money on more books. This manga prequel to the R.O.D OVA follows Yomiko before that story begins, including her first meetings with novelist Nenene Sumiregawa and with Wendy Earhart, then still a British Library apprentice working undercover as a schoolgirl.
