I'll be honest, but the first initial chapters were a bit of a struggle to read. Maybe because of the grammatical mistakes and misuse on tenses and adverbs. Not to add, I noticed that the author tends to be redundant too. And that made my eyes feel tired. (Imagine reading a paragraph that repeated the word "kill", "left", "walks" 5+ times) Although there was a slight improvement from chapter 13 onwards, I recommend that the author should be vigilant on proofreading and improving on your vocabulary to remedy that.
Lore-wise, I like how the author thought about how to make his "system" uniquely his by adding his own touch. I liked the way how he fashioned the quest part especially.
The Story & Characters though... is a bit lacklustre. Either that or the pacing was a bit off. Especially when it came to the MC's interaction with the opposite gender. I really saw him as a thirsty dude despite his dialogues were rational sometimes. Also the murdering parts and the implied pinning (well it is a harem) were a little awkward and robotic. I think using realistic references and putting genuine emotions would make those better.
Although I pity Kite for being thrown into the fray of the system but still, some parts on his character development may need work since I don't feel that attached to him. (or maybe because I got irked on some of his questionable actions)
