The reviews here are premature, as they judge the book halfway through and fail to appreciate its full potential. The main character, the MC, is not a violent anti-hero; his actions towards later adversaries are justified by their heinous nature. The supporting characters are well-developed, each with their own growth throughout the story.
The system's mechanics are introduced later on, giving readers time to understand its significance. It's important to clarify that there is no harem plot, despite initial interests from characters; romance is a subplot, not the central focus.
The MC's contractors are diverse, distinguishing him from typical harem protagonists. The world-building is extensive and evolves gradually, addressing many perceived inconsistencies along the way.
I must note that my experience took a downturn at chapter 352. Despite earlier emotional highs, the story fell into a clichéd pattern of continually escalating battles against stronger opponents. It's disheartening to see such a captivating narrative succumb to this predictable trope.
In summary, while the novel was strong up until that point, the recent development has led me to decide to stop reading.
