Jujutsu Kaisen

Jujutsu Kaisen is the defining dark shonen anime of the 2020s, blending supernatural horror, explosive high-stakes action, and surprisingly complex character work into one of the most compelling series of the decade. Animated by MAPPA — the studio behind Attack on Titan's breathtaking final season — JJK follows Yuji Itadori, a physically superhuman high schooler who swallows a cursed finger of the ancient demon Ryomen Sukuna and becomes his host. The series is legendary for refusing to play it safe: beloved characters die without warning, villains actually win, and the moral landscape grows darker with every arc. Gojo Satoru is one of the most iconic anime characters of the entire decade. Season 3's Culling Game arc is currently the most ambitious and intense storyline the series has ever delivered, cementing Jujutsu Kaisen among anime's all-time greats.
