Finished it, I put it on hold to read because it looks like misery p*rn. I love it that the author weave why we should care for each character even if your gut feeling that they will die in first arc. It's simply phenomenal in term of character but lacking in term of logistics and worldbuilding especially the magic and politics stuff (if you are looking for that then read youjo senki). It's super depressing maybe I could say it's indeed misery p*rn but a great one. It's anti-war story. The fact that first arc is the weakest part of story and when MC thehappiest, can't wait for peak arc to be adapted (4,5,6,8,and 10)
