The story is amazing, but the animation looks like a PowerPoint presentation, just like Bluelock. The art is awful; even the manwha has better animation. The eyes and the movement on combat scenes are garbage. They even use CGI or AI (idk) and it looks weird seeing a 3D character and a 2D one on the same time. I don't know why, but the story is a little different on the anime. It has minor changes, but the essence is still there. If you have the chance to watch this anime, I would recommend it, but don't expect good animation. (To be honest, the manwha is better.)
