"Fullmetal Alchemist: Brotherhood" may not have demons as such, but we will also find some enemies beyond the human that perfectly allow us to place it in terms of anime similar to "Kimetsu no Yaiba". However, it is not the action or the context that makes the anime earn this inclusion, but the most marked reason lies in the story of Edward Elric with his brother Alphonse. In a similar way in which Nezuko is turned into a demon, during a failed alchemy process Alphonse ends up being trapped in medieval court armor. In this way, both anime closely follow the story of two brothers
Both are really good shounen with great animation.
