Jujutsu Kaisen

Gege Akutami's dark shonen about teenagers fighting curses born from human negativity became a cultural phenomenon when MAPPA animated Season 1 in 2020. The Shibuya Incident arc in Season 2 is considered some of the best anime ever produced — fight choreography, emotional stakes, and plot twists that left the fandom in ruins. The prequel film Jujutsu Kaisen 0 earned $188 million. Over 90 million manga copies in circulation. It's the show that's replacing Naruto as the default "my first long-running shonen" recommendation.
