The quality of the comic is mediocre at best.
Character names keep changing frequently, which is confusing. He gains a summoning skill that initially allows him to summon a few weak skeletons, but suddenly he’s able to convert boss-level enemies into summons, without any clear explanation. Then, after a few chapters, he stops using this ability entirely, as if he forgot about it. Same thing with a couple of other skills and even his pet: he obtains a promising companion and then completely neglects it. Overall, the story feels all over the place, like the author didn’t have a clear plan, or maybe the comic adaptation is cutting out a ton of stuff.
