Given that it continues the storyline from the first series, Jinrou Game: Beast Side feels more fleshed out and developed, with more engagement from the reader on the stakes of the game now that we have characters who have been firmly established and given stronger backgrounds than in other Death Game Manga. The majority of the cast are still randoms who have been thrown into the game, but now we get to see a new version of the first manga unfold from a different perspective.
If you've played Werewolf, Mafia, or Town of Salem, I'm sure you agree that the Killer Roles are the most interesting to be, and I think that line of thought continues in this manga that allows it to shine better than its counterparts in the franchise. There are always more reveals and players introduced than in the last story which amplifies the drama. I must admit, despite the love I have for this manga, there is a particular death scene that ruins one of the more interesting characters and is poorly written in my opinion as it removes the greatest threat our main characters face. I suspect they were killed because the writer was likely unsure how to progress the story with such a powerful leader and investigatory antagonist. Besides that, I think the overall story is still as strong as your typical Death Game Manga.
If you enjoy the Death Game Genre, then why are you reading this? Go read the manga instead!
