Lucy has moved into a house in Magnolia where her guild Fairy Tail is located. As Lucy is talking about how great her house is Natsu and Happy barge in, to Lucy's dismay. As she fails to get them to leave she shows them her Celestial spirits before then opening the gate of Canis Minor to form a new contract with the spirit, which she names Plue. After inviting her to join him to make up a team, Natsu presents her with a job to steal a book from the mansion of Duke Everlue. They travel to Shirotsume Town to meet the client who is desperate to get the book. They find the book and Lucy insists on reading it because she beliefs it contains a secret despite Everlue furiously trying to reclaim the book.
