Minor spoiler: Amazing Manga for the moment! I just finished reading the 6th volume, It was pretty good. I think it's a really outstanding manga not because it has some kind of crazy plot, no Our Hero kill goblin because they killed his sister. But a good manga doesn't need to have a great plot to be enjoyable. I think the greatest strenght of this manga is the fact that it' really like a "Berserk cousin" I mean it's very different from berserk, But it has got all the stuff that I personally liked of That masterpiece. Gore, blood everywhere, epic fight a really enjoyable MC.I mean I simly love this manga, He resurrected my favourite manga genre The Dark Fantasy.
I understand the controversy of the rape scene.
But if you read Dungeon and Dragons, It cleary says that the only way goblin have to reproduce is by kidnap and rape women from small village without defense.
