Kafka Hibino is coming back. Honestly, after that cliffhanger where the Defense Force finally realized their best weapon was actually the monster they were trying to kill, we all knew a sequel was inevitable. Production I.G isn't silly. They saw the numbers. They saw the way the first season dominated Crunchyroll and even broke into the mainstream zeitgeist on X (formerly Twitter).
So, let's talk about Kaiju No 8 Season 2.
It’s officially confirmed. We aren't just guessing anymore. TOHO Animation and the official series socials have already dropped the teaser, and while some people were worried we’d have to wait three years like we did for One Punch Man or Attack on Titan back in the day, the timeline looks much tighter.
When can you actually watch Kaiju No 8 Season 2?
Early 2025. That is the window.
Specifically, the "Kaiju No. 8 Special Event" in Japan confirmed that the second season is slated for a 2025 broadcast. If you look at how Production I.G handles their workflow, a Winter or Spring 2025 release makes the most sense. They’ve already got the assets. The character designs are locked. Most importantly, the manga has plenty of material to pull from, so they aren't waiting on Naoya Matsumoto to draw faster.
It's actually a relief.
Sometimes sequels get stuck in production hell, but Kaiju No 8 Season 2 seems to be on a fast track. You’ve probably noticed the industry shifting toward these consistent yearly or bi-yearly releases to keep the momentum going. If you lose the audience, you lose the merch sales. And let’s be real, the Kaiju No. 8 merch is everywhere right now.
What is the story actually going to cover?
Season one ended right around Chapter 38 of the manga. Kafka is in custody. The Third Division is reeling. Director General Isao Shinomiya—basically the strongest man alive—is about to personally test if Kafka is a human or a biological hazard.

The next big chunk of the story is the Captured Kaiju Arc.
This isn't just a training arc. It’s a massive tonal shift. Up until now, Kafka has been the goofy underdog trying to fit in with the kids. Now? He’s a prisoner of war. The dynamic between him and Kikoru Shinomiya gets way more complicated because her dad is literally the guy holding the executioner’s sword.
But the real meat of Kaiju No 8 Season 2 will likely be the Kaiju No. 9 Identification Arc.
Kaiju No. 9 is the smartest antagonist we’ve seen in the series so far. He isn't just a big lizard that wants to smash buildings. He’s a strategist. He absorbs people. He learns. He’s basically the "Cell" (from Dragon Ball Z) of this universe, and his plan to dismantle the Defense Force from the inside is where the horror elements of the series really start to shine.
Expect more of this:
- Deeper looks into the history of the Daikaiju weapons.
- More screentime for Hoshina, who is arguably the coolest character in the show.
- The introduction of Gen Narumi.
Seriously, if you haven't read the manga, Gen Narumi is going to be your new favorite character. He’s the Captain of the First Division, he’s a total degenerate gamer, and he is absolutely terrifying in combat. His entrance alone will probably break the internet for a day or two.
The Production I.G Factor
There was some "discourse" online during season one about the character designs. People said they looked too "simplified" compared to the high-detail manga art. But once the fight scenes started? Those complaints died out.

The fluid animation during the Hoshina vs. Kaiju No. 10 fight was masterclass stuff.
For Kaiju No 8 Season 2, expect the same team to return. The "Simplified" designs are intentional. They allow the animators to push the squash-and-stretch and the high-speed movement without the character models breaking. It’s the same philosophy behind Mob Psycho 100. If the lines are too complex, the movement feels stiff. Production I.G wants this to feel like a kinetic, breathing world.
Why this series hit different
Most shonen protagonists are 14. Kafka is 32.
That is the secret sauce.
When you watch Kaiju No 8 Season 2, you aren't watching a kid discover the power of friendship. You’re watching a guy who failed at his dreams, took a "trash" job cleaning up guts, and finally got a second chance at life. It resonates with people who feel like they missed their window.
It’s also surprisingly funny. The humor doesn't always land for everyone—Japanese comedy can be a bit loud—but the chemistry between the Third Division members feels earned. You actually care when a generic background soldier gets stepped on.
Addressing the "Generic" Allegations
Some critics say Kaiju No. 8 is too "by the numbers."

"Oh, it's just Attack on Titan meets One Punch Man," they say.
Sure. Maybe. But execution matters more than originality. The way the series handles the "Kaiju Identification" system—where monsters are ranked by a Fortitude Level—adds a layer of tactical tension that a lot of other battle shonen lack. You know exactly how outmatched the humans are. When a Fortitude 9.0 shows up, you feel the dread because the scale has been established.
Kaiju No 8 Season 2 will raise those stakes. We are moving away from the "Monster of the Week" vibe and into a full-scale war for survival. The Defense Force isn't just reacting anymore; they are being hunted.
Actionable Steps for Fans
If you're vibrating with excitement and can't wait for the 2025 release, here is what you should actually do:
- Read the Manga (Volume 5 Onwards): If you want to stay ahead of spoilers, pick up the manga starting at Chapter 39. The art by Naoya Matsumoto is incredibly detailed—even more so than the anime in some parts.
- Watch the ONA/Specials: Keep an eye out for any "B-Side" content. Sometimes studios release small character shorts between seasons to flesh out the side cast.
- Revisit the Soundtrack: The music for season one was composed by Yuta Bandoh, and it’s genuinely some of the best orchestral-electronic fusion in recent years. Listening to "Monsters Without Names" on repeat is a valid way to spend your time.
- Check the Blu-ray Releases: Often, the home video releases in Japan (and eventually the West) include cleaned-up animation and extra scenes that weren't in the broadcast version.
The wait for Kaiju No 8 Season 2 won't be as long as you fear. The production cycle is healthy, the fan base is growing, and the story is only getting more intense from here. Kafka’s journey from a literal "sweeper" to the most wanted man in Japan is just getting started.
Keep your eyes on the official TOHO Animation channels for the specific month-and-day announcement, which usually drops about 3 months before the premiere. Based on the 2025 confirmation, we should have a firm date by late 2024.
