Natsu Dragneel, age 5, just finished his second job sense being in fairy tail. He got 50,000 J and a gold and black notebook that has a spell on it that makes it not wear out, but get thicker on his birthday. It doesn't have  normal pages though, the pages are blank music pages.

Later on, after the tenru island time gap, the book is thicker as it aged but not Natsu.
