its been mentioned in previous comments but the author is definitely a man of culture lol the plot is sprinkled with references from game of thrones (snow elf arc), one punch man (jinwoo's daily exercise regimen) and most recently hunter x hunter to name a few
Yeah, it kinda makes you wonder about the originality and consider the possibility of plagiarism? Idk, just a thought
I wouldn’t be worried about it. A lot of shounen have similar plots between each other, for example, the isekai shounen have a lot of story with a male mc that is a a high school student that become an op hero in another world and obtain a harém. Or for example, Naruto and black clover, they have a lot of similarities. And someone once told me that boku no hero academia have a lot of references and similarities with Star Wars. So from my opinion this one have more “originality” than most of stories that I already read or watched.
saw the author and i was like IKE REIBUN???? The god that created Not Equal and Kobi no Kyoujin Trilogy??? Gotta read
