"In order for something to be obtained, something of equal value must be lost." Alchemy is bound by this Law of Equivalent Exchange—something the young brothers Edward and Alphonse Elric only realize after attempting human transmutation: the one forbidden act of alchemy. They pay a terrible price for their transgression—Edward loses his left leg, Alphonse his physical body. It is only by the desperate sacrifice of Edward's right arm that he is able to affix Alphonse's soul to a suit of armor. Devastated and alone, it is the hope that they would both eventually return to their original bodies that gives Edward the inspiration to obtain metal limbs called "automail" and become a state alchemist, the Fullmetal Alchemist. Three years of searching later, the brothers seek the Philosopher's Stone, a mythical relic that allows an alchemist to overcome the Law of Equivalent Exchange. Even with military allies Colonel Roy Mustang, Lieutenant Riza Hawkeye, and Lieutenant Colonel Maes Hughes on their side, the brothers find themselves caught up in a nationwide conspiracy that leads them not only to the true nature of the elusive Philosopher's Stone, but their country's murky history as well. In between finding a serial killer and racing against time, Edward and Alphonse must ask themselves if what they are doing will make them human again... or take away their humanity. 錬金術、それは「等価交換」の原則のもと、物質を理解、分解、 そして再構築する、この世界で最先端の学術である。 この錬金術において、最大の“禁忌"とされるもの「人体錬成」。 亡き母親を想うがゆえ、禁忌を侵し、全てを失った幼き兄弟。 巨大な鎧に魂を定着された弟、アルフォンス・エルリック。 機械鎧(オートメイル)をまとい、「鋼の錬金術師」の名を背負った兄、 エドワード・エルリック。 二人は失ったものを取り戻すため、「賢者の石」を探す旅に出る。 兄弟は「賢者の石」の真実に近づくにつれ、大きな陰謀の渦中へと突き 進んでいく。 暗躍する人ならざる者たちの存在。 徐々にその本性をむき出しにする軍事国家アメストリス。 虐げられた民の果て無き憎しみと復讐の念。 錬金術がもたらす幾多の悲劇。 点在する悲劇は、やがて線になり、人を、民を、そして国すらをも巻き 込んでいく。 兄弟は絶望と希望の狭間の中、それでも前に進む--。
