Anime is constantly evolving especially within the shonen genre, and recently a subversive trio emerged, challenging the status quo with a visceral intensity. Hell's Paradise, Jujutsu Kaisen, and Chainsaw Man have collectively shattered the glass ceiling of thematic limitations, earning them the title of "Dark Trio" within the anime fandom. Complex themes that deal with sacrifice, violence, and unpredictable story beats give the audience and fans of these anime an engaging yet sometimes merciless experience.
