Marking twenty years since Fullmetal Alchemist began serialization, this companion volume collects the gaiden side stories the main run never had room for, including "The Blind Alchemist," "Tales of the Master," "Long Night" and "The Beginning of the Journey," along with the interstitial chapter 44.5. It also gathers the prologue comics drawn for three tie-in PlayStation 2 games and a new prose short following Jean Havoc and Maria Ross in the run-up to the "Promised Day." The book is a supplementary collection rather than new plot for the Elric brothers.
