About TV Anime Fullmetal Alchemist: Brotherhood
Serialization began in 2001 in the monthly magazine Shōnen Gangan (Square Enix), and the series went on to win the 49th Shogakukan Manga Award in 2004. Fullmetal Alchemist, the hit comic by Hiromu Arakawa, was adapted into this TV anime. To bring their late mother back to life, the Elric brothers committed the forbidden act of "human transmutation" and lost everything as a result — the story follows their journey to reclaim what they lost. The TV anime aired from April 2009 through July 2010.
