Despite the idea appearing slightly novel at first, the story quickly shows its limits, both in originality and execution.
The protagonist is absurdly over-powered and oblivious, their past is basically a shadow that never really affects much past the early chapters, ridiculous plot-points galore (look forward to when they'll try to adapt from the novel how the prejudice against dark elves spread around the kids in the city) are just some of the things you can expect by reading this.
The setting wants to be both completely cutthroat and a cozy adventure with a young party (with everything in between) and it just doesn't work.
Expect half of the people the protagonist meets to be perfectly reasonable and able to fit in our modern society, while the other half will resort to violence for the pettiest of reasons and nobody is thrown in jail or at least face a strong rebuke from law enforcement.
The reasonable people will also somehow accept that violence is the norm, making you wonder how they can be well-adjusted if that's the view they hold or why they behave the way they do, or find the pseudo-pacifism of the protagonist so weird and selfless.
I hope this will serve as a warning to others, so they won't waste time with this. It's every other bad isekai with a thin veneer to disguise itself, but it doesn't do anything at a competent level (except for the art).
