Fullmetal Alchemist: Volume 8 - The Altar Of Stone
As the Elric brothers are leaving Yock Island, a strange boy emerges from the foliage with no memory of how he arrived. In explicably, he can perform alchemy without a transmutation circle. Even stranger, he can transmutate his own body, merging with his surroundings! Meanwhile, the search for Scar gets a forward leap as a former military officer spots him in the southern slums.
Elsewhere, Lt. Colonel Archer makes his move for the mysterious wild boy, who he believes is a homunculus conspirator. Infuriated by the arrest, Izumi leaps into action, single-handedly attacking the military with her staggering alchemic power.
