An unknown man is found on top of the White House. The police are unable to stop this man, and he, with his unusual powers, destroys the entire building. When asked who he is, the unknown man replies, "I-Jin". He then asks where the Library of Congress is and goes off to steal thousands of manuscripts.
Enter Yomiko Readman, a total bookworm whose room is littered with thousands of books in multiple languages. After buying a rare book for a ridiculous sum of money, she is attacked by a swarm of insects summoned by a man who has an interest in the book she is reading and steals it from her.
It turns out that he is part of a terrorist organisation called I-Jin as well, the same people who attacked the Library of Congress and stole all of their books and manuscripts.
Fortunately Yomiko is actually a special agent for the British Library who has the power to manipulate paper Yomiko is assigned to the case of the stolen book along with "Ms Deep", who has the power to phase through objects, and Drake Anderson, a demolitions expert
Together, they go on their mission and find out that the stolen book is more important than they think.
