Aside from the cannibalism aspect, I'd say it has a very cliche high-school death game premise. If you've read Ousama Game, the structure of the games is pretty much the same but I think the sheer brutality and creativity of the challenges in this manga completely beat Ousama Game. In both manga, you get the usual protagonist who is fairly popular, righteous, and deadset on basically saving everyone, which is really the standard male protagonist trope for these types of stories. But unlike in Ousama Game, this manga's ending isn't actually half bad. For me, it at least managed to tie up all loose ends and uncover all the mysteries. It wasn't the most satisfying ending for sure because let's face it every likable character dies and we're left with the bland protagonist, Shouta, but it did make sense in the end. I also enjoyed the creepy open-ended panel we're left with in the last chapter that really cements the horror aspect of this manga.
I've been hating on the protagonist a lot but I do appreciate how the story doesn't end with him going into a spiral of insanity where he suddenly becomes a pro at the game. While Shouta does get understandably depressed, he at least doesn't suddenly improve and start killing off people for his own benefit. It was actually a nice touch that he stayed upright and true to his beliefs until the end, and it was those same values that led him to uncover the truth about the game. While the manga is fast-paced and some of the characters are severely underdeveloped, the writing and plot were pretty consistent. From the beginning, we were already given a few hints that tied into the mystery of the game and that's exactly what made the ending so believable. There are a few scenes and side stories that seemed really unnecessary to the plot, like the sex cult and just a lot of the sexual assault that seemed to happen almost every other chapter. But disregarding those really horrific visuals, it's a decent read that you can easily breeze through in one sitting. There's a good chance you'll be traumatized and disturbed by the end of it, but I personally think it's entertaining enough.
