This manga suffers from a severe case of edginess, surprisingly the main character is not the core of the problem but the world, all the monsters do is rape and kill the other characters, at least they have the decency of treating those subjects with the appropriate weight, you never think they get past that easily and all the characters are appropriately fucked in the head for the situation they are in, the MC starts with a revenge motivation and although the story fails to make us hate the bully, to the extent the MC does, it gives us a breath of fresh air when he abandons the revenge mentality.
The synergy of the characters are a little underbaked and the "romance" is a little rushed, the constant push for sexual themes makes the world feel too much tiring and unforgiving, if they had spread out more the time of the story maybe it would be better, apart from the forced harem troupe and the MC being the only man that we see for 80% of the story (and surprisingly the least well written here), the fighting and magic is "realistic", for better or worst it really feels like real people sometimes, if you can excuse the high amounts of edginess and constant showings of rape and violence I would say that it is a 6.5/10, if it was a less gruesome and the MC showed a little more of his backstory (and character) it would be an 8/10.
