Kaiju No. 8 Season 2 Debuts with New Arcs, Strong Defense Force

Kaiju No. 8 Season 2 premiered on July 19, 2025, on TV Tokyo and globally on Crunchyroll, continuing the story with the Kaiju Weapon Arc and the Compatible User Arc. The season introduces new characters like Gen Narumi, the unpredictable captain of the elite First Division, whose combat skills and eccentricity add depth and excitement to the series. While the animation quality has notably improved, some critics feel the season’s pacing is hindered by filler scenes and an overly long battle sequence, which detracts from the otherwise intense and strategic monster fights. The season picks up after the manga’s recent conclusion, offering fans a chance to relive the story with enhanced visuals and new plot developments, especially focusing on Kafka Hibino’s uncertain fate within the Defense Force. Despite these strengths, the late July release and pacing issues have made it difficult for Kaiju No. 8 Season 2 to stand out in the competitive summer 2025 anime lineup. Overall, the season balances action, character development, and emotional stakes, though some fans and reviewers hoped for a tighter narrative.
