Hell's Paradise is one of three anime series that make up the unofficial "dark trio," alongside Jujutsu Kaisen and Chainsaw Man. All three are bloody, gritty action shonen series where the heroes are sometimes as monstrous as the villains, which is what sets these series apart from the original shonen "big three." But while the dark trio's series all have plenty in common, such as monsters and gore, they have some differences, too.
