(Synopsis from the back cover):
«The weakest hunter of all mankind!
E-rank hunter Jinwoo Sung has no money, no talent, and no prospects to speak of—and apparently, no luck, either! When he enters a hidden double dungeon one fateful day, he’s abandoned by his party and left to die at the hands of some of the most horrific monsters he’s ever encountered.
But just before the last, fatal blow…
PING! [Congratulations on becoming a Player.]»
In a world where mysterious doors have appeared, leading to dungeons teeming with monsters, some humans become hunters with special abilities. Sung Jin-Woo is the weakest of them all, barely surviving while trying to help his family. After an extreme event in a dungeon, he receives a unique opportunity that will allow him to grow in power in a way never before seen, beginning a perilous journey of self-improvement.
The story starts strong from the very first chapter, generating a powerful sense of fear, tension, and anticipation. It's a very fast-paced and addictive read, which you can read very quickly and which works practically like a video game: levels, upgrades, constant progression. However, beneath this entertaining surface, the overall tone is extremely dark and sinister.
The violence is constant and often graphic: brutal combat, deaths, murders, and life-or-death situations are central to the story. Added to this is an environment where hunters are driven primarily by money and self-interest. There is no sexual content and the language isn't particularly vulgar, but the graphic violence is very intense.
The most problematic aspect is the protagonist's development. Jin-Woo begins as a weak and relatable character, but as he gains power, he becomes increasingly cold, arrogant, and unpleasant. He adopts a survival-of-the-majority mentality, justifying violence, revenge, and taking the law into his own hands. At several points, he shows a willingness to use others as mere means to become stronger.
This moral degradation is progressive but evident: the protagonist ends up being far from exemplary and even despicable in some respects, although he hides behind apparent good intentions. The work doesn't present this change as something negative, but rather as a logical evolution, which can be confusing.
Ultimately, it conveys a very clear idea: that what matters is being strong, powerful, and self-sufficient. A very attractive power dynamic today, but also dangerous, especially for readers with limited formation. Any reference to values such as charity, humility, or dependence on others is completely disregarded.
This is clearly reflected in lines like the following, taken from the anime, which perfectly summarizes the protagonist's mindset:
"I've always been mocked for being weak... Because if you're strong... if you have overwhelming strength, you always have the advantage... If you're weak, you can't do anything... kindness won't save me... That's why I have to become much stronger!"
Overall, it's a very entertaining and absorbing work, but also violent, dark, and morally problematic. It starts off exciting, but as it progresses, it can become unpleasant due to the protagonist's drift. It doesn't convey clear positive values and can easily be confusing, making it less than ideal, despite its current enormous success—including its popular anime adaptation, one of the most-watched.
