Like a lot of series that focus on leveling systems, Boushoku no Berserk has an issue with stat inflation and balancing in general. This is even despite the author’s inclusion of a reset mechanic… because for ~some reason~ that same mechanic is tied to a weapon which requires exponentially more stats to unlock higher evolutions.
Still, the first three books manage to keep things under control for the most part and end up entertaining enough. The fourth however just has a parade of issues: Random guys stronger than the divine dragon just hanging out in the city the entire time, Myne’s baffling character assassination, the way Memil ends up being treated despite being an unambiguous victim, and the author apparently forgetting both that gluttony devours souls and that anyone with E-level stats is supposed to be immune to the paralyzing gaze of those with higher stats then themselves.
Just a total mess I have no interest in following any further.
GM ga Isekai ni Login Shimashita. on the other hand doesn’t need to worry about balancing since it’s an overpowered protagonist series with a literally invincible lead. Said protagonist’s personality is odd in that while he’s altruistic, he’s also a bit of a sociopath that isn’t phased by dismembering people… and has the bizarrely nonsensical belief that actual slavery is somehow beneficial (for the slave) when compared to modern-day wage slavery.
Strange personality aside, the rather abrupt/half-assed romance elements are the only other issue. Seems likely this will turn into an ‘ever-growing harem’ type of thing with little actual thought put into the relationship dynamic.
