After having watched fullmetal alchemist and it being an other worlds experience the fmab writer is back and this anime has a really intriguing premise. If I were to only base it off the first promotional image I would never have been able to guess what this anime would be about. Everything about this anime gives fmabs great charachter vibe and I love the different daemons. The animation is very fmab like and the anime has a great premise. Looking forward to see how this anime develops and see the fully fleshed out relationship between the daemons and the two siblings
