To tell the truth, I don't know exactly how to evaluate a manga and what the criteria are, so maybe the review won't help many people.

Without mentioning anything from the story, I will mention things that were inspired by other series or inspired some series that came after it.

The story is Dark fantasy in a medieval era like Beserk, besides that this particular series seems to have given ideas to a very well-known series like Attack on Titan in terms of the story's progression.

I should mention that it consists of 27 books with 180-190 pages each. At the beginning, the drawings were somewhat amateurish, especially in terms of body characteristics such as limbs being overly large for the body, but over time there is a tremendous improvement in all areas, from the environment to the details in facial features and shadows. Besides that, the monsters stand out a lot from other series, I would say it's a mix between Tokyo Ghoul and Beserk.

Relatively easy to read because it doesn't bombard you with excessive information and tells you slowly, I had encountered this particular problem in another series where it told you everything in a few panels, resulting in many times having to flip pages to remember or connect the information because I might have missed or forgotten something.

It emphasizes battles more while later it starts to unravel the questions, the story is not overly complicated but has many characters that resemble each other at times and you may get confused.

As for evaluation, I wouldn't put it among the best series but it is a pretty good series for those who have read or seen the most famous ones, besides that it is complete so you can read it from beginning to end, you won't have the problem I encountered with Hunter x Hunter or Beserk which have not been completed.
