The action-packed anime series Ninja Kamui is officially returning for not one, but two new seasons! Adult Swim made the exciting announcement at the Annecy International Animation Film Festival, confirming that production is already underway for Season 2.
Higan’s Fight Continues in Ninja Kamui: Red Vendetta
Season 2 has been subtitled Red Vendetta and will follow Higan as he uncovers a new conspiracy with cataclysmic potential.
Adult Swim has released an early tagline for the upcoming season: “The next season, Ninja Kamui Season Two: Red Vendetta, will follow Higan as he uncovers a new conspiracy of cataclysmic proportions.”
Production Details
Ninja Kamui is produced for Adult Swim by Sola Entertainment. While E&H Production handled the animation for Season 1, it remains unconfirmed whether they will return for Seasons 2 and 3.
The Creative Team Behind Ninja Kamui Season 1:
- Director: Sunghoo Park (known for Jujutsu Kaisen Season 1)
- Assistant Director: Yui Miura
- Character Design Draft: Takashi Okazaki
- Series Composition: Shigeru Murakoshi
- Character Design: Sayaka Koiso
- Art Director: Yann Rugaru
Controversy and Critical Reception
Despite some mixed fan reactions to the show’s direction, particularly the introduction of mechs and robotics later in the season, Ninja Kamui has been a significant hit for Adult Swim. Some viewers felt the initial episodes, focused on hand-to-hand combat and ninjutsu, were stronger than the later episodes that incorporated more science fiction elements.
Warner Bros. Discovery stated that Ninja Kamui performed well across platforms, similar to their true-crime series and other adult animation titles. The anime was also awarded “Best Original Anime” at the 2025 Crunchyroll Anime Awards.
Where to Watch
If you missed out on the first season, Ninja Kamui is available for streaming on HBO Max in North America.
A Quick Recap of Season 1
Ninja Kamui follows Joe Higan, a former ninja who escaped his clan and sought refuge in rural America with his family. Living under the alias Joe Logan, he tries to hide from his violent past. However, his former organization ambushes him, seeking retribution for his betrayal of their ancient code, resulting in the death of his wife and son. Higan rises from his seeming death and embraces his former self, Ninja Kamui, to avenge his family and friends.
From Hiatus to Renewal: The Road to Seasons 2 & 3
The journey to renewal wasn’t without its bumps. Sola Entertainment initially confirmed a second season alongside the announcement of the NINJA KAMUI: SHINOBI ORIGINS game last June. However, the announcement was quickly retracted, with Adult Swim’s senior vice-president Jason DeMarco stating that no decision had been made.
Adult Swim Leans into Original Anime
Adult Swim has a history of original anime adaptations, though some, like Junji Ito’s Uzumaki, Fena: Pirate Princess, and Shenmue The Animation, were “one and done” projects. The renewal of Ninja Kamui for two seasons indicates a significant investment and confidence in the series’ future.
What to Expect From the New Seasons
According to the announcement, the upcoming seasons will explore a new arc involving a conspiracy with “cataclysmic” consequences. This pivot could be exactly what the show needs to win over more skeptical fans. By expanding its world and raising the stakes, Ninja Kamui Seasons 2 and 3 could deliver a deeper and more emotionally resonant narrative.
With a trusted team and increased investment, the creative direction may sharpen in future episodes. Adult Swim’s decision to renew it for two more seasons suggests the network sees long-term potential beyond current reviews. The show’s international fanbase, strong late-night ratings, and viral action clips on social media all hint at deeper audience engagement than the Rotten Tomatoes score suggests. For Toonami, the series has helped reinvigorate its anime lineup with fresh, original content.
Initial Reactions and Fan Sentiment
News of the renewal has sparked excitement and discussion within the anime community. While some fans were critical of the first season’s later developments, many are hopeful that the new seasons will address those concerns and deliver an even more compelling story.
Sunghoo Park’s Impact
Directed by Sunghoo Park, known for his dynamic action sequences in Jujutsu Kaisen, Ninja Kamui has been praised for its visual storytelling and fight choreography. While some viewers criticized its storytelling and pacing, the anime still managed to pick up significant accolades, including “Best Original Anime” at the 2025 Crunchyroll Anime Awards.
The Future of Ninja Kamui
With Ninja Kamui renewed for two more seasons, fans can look forward to more action, intrigue, and ninja vengeance. As Higan delves deeper into a new conspiracy, the series has the opportunity to refine its storytelling and solidify its place as a standout original anime. Stay tuned for more updates on release dates, production details, and what awaits Higan in Ninja Kamui: Red Vendetta.
