Munich, 1923. Two years have passed since Edward Elric was transported to our world from his own, where his homeland, his friends, and his younger brother, Alphonse, remained. Deprived of the ability to practice alchemy, Ed has been conducting research in rocket technology all this time alongside Alphonse Haiderich—a young man who bears a striking resemblance to his younger brother—hoping that this would lead him to a way back home. So far, his efforts have been in vain, but when he learned that the Thule Society—an occult group closely associated with the Nazi Party—had discovered the key to the location of the legendary, mystical land of Shambhala, Edward’s hopes were reignited. Meanwhile, in his home world, Alphonse Elric delves deeper and deeper into the mysteries of alchemy, searching for a way to reunite with his older brother.
