Don't go for the bad score, give this manga a try, it is really breathtaking!
I can't deny that it has clear defects, but still I think the experience of reading this manga is worth it. There are two flaws that stand out: the end, it doesn't represent how good the story went and the introduction of a villain who doesn't have an ounce of charisma. Regarding the first defect, I think the author did well not to take the most obvious path, but there was a lack of progress, the final fight was not as exciting as others and the characters did not have the emotion that was expected. About the second defect, I didn't really like this villain, but he served a purpose and was true to himself at all times, everything in this work and even he fits in with the plot.
The characters, the construction of the world and the revelation of the mysteries for me are strong qualities of the work, especially the characters, the protagonist for me was the best female protagonist I have ever seen, including anime, she performs very well the duality of a protagonist who fights for the good of others and at the same time is someone dangerous, who grows exponentially while still being the same character you met in the beginning. There are 3 other characters that I got attached to, they don't need to be so well developed, but each scene they appear in has an impact, and they are just cool, really cool, really really cool. This story is a lot about it, cool characters doing cool things in extreme situations.
This manga made me scream with euphoria at various times, it is stupidly fun and is a sensational work in terms of action, without a doubt it was marked as one of my favorite manga
