While slightly shorter than its predecessor in length, One Piece Blue is much wider in scope, comprising two main sections:
- Data File, indexing virtually every character in addition to every Devil fruit, animal, and island encountered thus far
- Making of One Piece, collecting a considerable amount of behind-the-scenes material supplied directly by Eiichiro Oda
The contents proper are preceded by a set of commemorative stamps and iron-prints themed after the Straw Hats, as well as a One Piece Colors collection featuring:
- Luffy from Weekly Shonen Jump (1999) #35's cover
- Usopp from Chapter 221's color spread
- Vivi from Weekly Shonen Jump (2002) #10's frontispiece
- Chopper from Color Walk 1's cover
- Sanji (and Luffy) from Chapter 64's color cover
- Nami from Chapter 32's color cover
- Robin from Chapter 226's color spread
- Zoro from Weekly Shonen Jump (1999) #49's cover
- A collage melding Gold Roger from Chapter 1's first panel, Luffy from Weekly Shonen Jump (1998) #17's cover, and the "Great Age of Piracy" splash page (complete with narration) concluding Chapter 7
History of the Adventure
Names and profiles every character from the first twenty-four volumes, up to Chapter 226's Shoujou and his Utan Divers. Each character is indexed by the volume (and, to a lesser extent, the exact page) of their first appearance.
Unlike One Piece Red's character files, this section does not restrict itself to "major" characters, and includes a number of one-panel background characters (e.g. Samurai Batts), unseen characters (e.g. Willie Gallon), inanimate objects (e.g. Luffy's Fish-Man sketch from Chapter 69), author in-jokes (e.g. "AfrOda") and even caricatures of One Piece's real-life editors Takanori Asada and Takahiro Habuta. As a result, the individual profiles are much shorter, ranging from one page to one-twelfth of a page.
Strange Animals Guide
Examines the many different Animal Species inhabiting the world, following a double-axis spectrum divided into four categories: "Big Friendly" (A), "Small Friendly" (B), "Big Savage" (C), and "Small Savage" (D).
Encyclopedia of the Akuma-no-Mi
Provides a brief overview of Devil fruits, followed by an index of all specimens (and their respective users) up to Hina's Ori Ori no Mi. Zoans - the only type formally identified thus far - are given extra focus.
A collection of semi-serious rankings on many different topics, all arranged and narrated by Usopp.
Eiichiro Oda's Workshop
An in-depth diagram of Eiichiro Oda's home and workshop, divided into four quadrants.
Treasure of Eiichiro Oda
Examines the many oddities and memorabilia that Oda stores in his home, among them a cow skull, authentic pirate weapons, various action figures, and an autographed sketch from Akira Toriyama.
Transcribes an interview between Oda and an unidentified fan, consisting of 76 questions organized into five sections.
Process of Making One Piece
Gives an overview of Oda's standard art tools (circa 2002), followed by an eight-stage examination of how a single page from Chapter 148 progressed from rough breakdowns to inked-and-lettered final draft.
Depicts a number of the gag logos that Oda sometimes sketches onto the title pages he submits to Shonen Jump (inevitably replaced with the "proper" One Piece logo in actual printings). Among the more notable:
- A Typhoon no. 16 Nears logo to mark the approach of Typhoon Nari
- A Dragon Ball logo "accidentally" sketched while thinking about Goku's latest battle
- A Gand-iece logo, complete with sketch of Mahatma Gandhi
A thirty-question test on One Piece trivia, with six possible rankings.
- This book's cover illustrations of the Straw Hats would be reused for the cover of the 2003 video game Ocean's Dream (albeit with different outfits).
- ↑ Paramecia and Logia types were first identified and explained in the Skypiea Arc, around five months after this databook's publication.
