Amazing show so far. These 12 episodes only adapt 45 of the 270 chapters so there's still a lot to come. This excuses some of the issues with the anime, like the story focusing a bit too much on the mc and not elaborating on the universe itself, like where did the portals come from? The artstyle and animations are great, my eyes were glued to the screen during fighting scenes, it's also very graphic. The characters are a bit lacking, as I already mentioned the story focuses too much on the mc and we barely see anything of the side characters besides an introduction.
