Meanwhile, Major Kimblee and a ruthless General Raven make Major General Olivier Mira Armstrong an offer she can't refuse... Whose side is she on, really? And how far is she willing to go?
In an alchemical ritual gone wrong, Edward Elric lost his arm and his leg, and his brother Alphonse became nothing but a soul in a suit of armor.
