Tv version:

Edward was killed by a rabbi (a changeable artificial man), and Al revived Edward with the stone of Tessa. Al walked to the other side of the door, and Edward exchanged four years' experience for Al. However, after she became a mother, Aier lost all her memories. Aier wanted to swim with her brother in order to learn from Quan. Edward was on the other side of the door, lost his hands and feet, and wanted to return to the real world, so he studied rockets.

Theater version:

Love opened the door, and my brother came to the world of alchemy with the army of the real world. With the help of love and the colonel, he defeated the real-world army, and love and Edward returned to the real world (by the way, Edward's father died)
