Ninja Kamui Renewed for Season 2 and Season 3 by Adult Swim

It’s official. Ninja Kamui isn’t done slicing through the anime scene just yet. After shocking viewers with its gritty action and raw emotion last year, the series is returning for not one, but two new seasons. Yep - Season 2 and Season 3 are coming, and the next chapter is already titled Red Vendetta. The announcement dropped during the Annecy International Animation Film Festival this past June, and fans haven’t stopped buzzing since.

Red Vendetta Signals a New Level of Danger

So, what do we know about the new seasons? Red Vendetta, which is the official title for Season 2, is said to dive deeper into conspiracies and vendettas that threaten the very world Higan walks in. According to multiple sources, both Season 2 and 3 are already in development, with Sola Entertainment back at the helm. Animation studio E&H Production handled the first season, but it’s still unclear if they’ll return.

As for a release date? Nothing’s confirmed yet, but if we follow the timeline - Season 1 aired February to May 2024 - it’s fair to guess that Red Vendetta might land somewhere in late 2026 or early 2027. And if that happens, there’s a good chance Season 3 will follow in 2028. That’s speculation, of course, but it’s a pattern fans are banking on.

Quick Recap of Season 1 for Those Who Need a Refresh

Season 1 introduced us to Higan, a former ninja who had escaped his violent past and built a quiet life with his wife and child. But peace is fragile. One night, his entire family is assassinated by the very forces he once served. That was the end of his normal life - and the start of something far more brutal.

From that moment on, Ninja Kamui morphed into a fast-paced, heart-wrenching journey of vengeance. As Higan teamed up with two FBI agents looking into the same killings, layers of a much deeper, sinister global conspiracy started to unfold. These weren’t just random murders. This was something orchestrated. And Higan? He wasn’t just a rogue ninja - he was a ticking time bomb with a vendetta. One moment in the series really captures his mindset: in the show Higan declares,

“I don’t want to simply just surrender my life to fate. If I must follow something, then I want to follow my heart.” - Higan

Despite mixed reviews in some corners (a 57% audience score on Rotten Tomatoes isn’t great), Ninja Kamui went on to win “Best Original Anime” at the 2025 Crunchyroll Anime Awards. That speaks volumes about the connection it made with the anime community. And if you missed the hype, you can watch the Season 1 trailer down below:

What’s Likely Coming in Season 2 and beyond

Now that Red Vendetta is officially on its way, what exactly can we expect from these next chapters? While the series is original and doesn’t follow a manga, several clues and early announcements give us a rough idea of what’s coming:

1. Higan will uncover a new conspiracy on a much larger, global scale
2. New characters and enemies from his past are expected to appear
3. Psychological depth and emotional stakes will likely increase
4. More blood-pumping fight sequences with hybrid ninja-tech combat
5. Exploration of loyalty, loss, and revenge taken to extreme levels

The title Red Vendetta itself screams personal stakes. This isn’t just about uncovering secrets anymore - it’s about settling scores.

Why Fans Fell in Love with Ninja Kamui

If you watched Ninja Kamui, you probably know why it hit so hard. The fight scenes were more than just flashy - they had weight. Every move felt like it mattered. The pain behind each punch and slice was clear in Higan’s eyes. And then there’s the pacing. It didn’t waste time with filler or cheap tropes. The show hit the ground running and didn’t let up.

But beyond the action, people really connected with the emotion behind it all. The loss. The grief. The fury. Viewers saw a man unraveling while still trying to hold on to some piece of his humanity. And that duality? That’s what made it special.

It also helped that the soundtrack slapped, and the opening/ending sequences were top-tier. Combined with the voice acting (especially in the Japanese version), the whole thing had a level of polish that took folks by surprise.

Other Anime to Keep on Your Radar

While we wait for Higan’s return, there are a few other titles worth diving into. Chained Soldier Season 2 is heating up with its own intense power clashes and dark twists. It’s one of those series that surprises you with how deep it gets. Meanwhile, From Old Country Bumpkin to Master Swordsman Season 2 continues to be a hidden gem, especially for fans of rags-to-riches stories with sharp animation.

Final Thoughts

Ninja Kamui didn’t arrive with the flash of a mega-franchise like Demon Slayer, but it carved out a space all its own. As producer Joseph Chou noted when discussing the show’s creation and development,

“Working with Adult Swim - we were enabled to produce these kinds of titles without having to rely on Japan domestic market trends.” - Joseph Chou

Gritty, fast, and unflinchingly emotional, the show gave anime fans something refreshingly different. Now with Red Vendetta and a third season in the works, Higan’s story is far from over.

The coming seasons promise more of everything - action, mystery, heartbreak, and probably a lot of blood. You can also catch up on all 13 episodes of Season 1 now streaming on HBO Max and Adult Swim. So sharpen your blades, clear your watchlist, and prepare - Red Vendetta is coming. And it’s not pulling any punches.
