Okay, Imma be honest with you. The first 5 episodes or so of this anime are absolute trash. I don't know WHAT Shinobu Otaka was thinking, but they're a god awful mess and I think the primary reason why the ranking for this show is so low. But if you stick with it, everything from episode 6 to 12 is actually pretty good, and everything past episode 12 is PHENOMENAL. If you like Magi, this has a really similar vibe. It's well executed, and Shinobu Otaka shines with her worldbuilding, mixing of fight scenes with emotional story beats, and making you feel like the characters arereally human. The animation is well done and the pacing is actually done really nicely so you can feel the growth of everyone in the story. I cried so much at the last couple episodes too

Ignore anyone who says the MC is trash, because those people just want your run of the mill anime protagonist who "rages" and powers up fast so they can "kill everyone". This MC is not that, this show is not a power fantasy. This is an actual story and it's genuinely very well done (after those first few episodes).
