@melbisbelbis not really. I think we should remove the harem tag. At the point where the novel is translated, only 2 girls. And both of them were encountered very early in the story (The second is encountered early but join later). I doubt (and hope) the number won't increase because it will go against the whole idea behind the story. (IMO: up to 2 girls: not a harem; 3 girls not a harem if they are the only ones flirting with the MC and the characters is well established; 3 girls but often others flirting or lackluster in personalities: Harem; 4 or more: Harem)
About everyone saying it's generic: it's not that much. First the MC is OP but not that much, he will often encounter strong threat that could have killed him if not careful. He is sort of a glass cannon. He will get a powerful weapon but with limited shots and while his stealth is OP, there is a lot of characters that can sense his presence by instincts. At the same time, stat points are hard to get and he isn't the only one who get them. In fact, everybody get skills points but only him can choose where to put them. The rest of the people have auto-assign. Hence, he is a minmax character: for example: nearly everybody have points in vitality but he never put a single one in it and focus on stealth. (Hence, why he is a rule breaker)
There will be an other character truly OP (another otherworlder) but while she will be friend with the MC, it stops here, she doesn't even join the group. (And the reason for being OP is explained (not a cheat))
While the novel isn't a masterpiece, it's still very good. So yeah, I recommend reading it. Though, it's a shame the art isn't very good.
