I’ll be honest, my initial impression of Kaiju No. 8 was “meh”. Another underdog, another central protagonist with powers others don’t have. It was fine, but I dropped-off after a couple of episodes. Then, about a year later, I was urged to properly give it some time. So I did and I feel like an idiot for not paying attention in the first place.
Kaiju No. 8 is one of the most refreshing, thrilling, and downright fun additions to modern Shonen anime. Brought to life between Production I.G (masterminds of sci-fi action) and Studio Khara (the visual visionaries behind Evangelion), the series manages to combine blockbuster monster mayhem with genuine heart and sharp comedy.
It just deserves to be watched, and it’s always interesting. Low on the filler content and high on the action.
The Premise
In a Japan constantly under siege by colossal, destructive monsters known as Kaiju, humanity’s only line of defence is the Anti-Kaiju Defense Force.
Enter Kafka Hibino. At 32 years old, Kafka has long given up on his childhood dream of fighting on the front lines alongside his childhood friend, Mina Ashiro. Instead, he works for Monster Sweeper Inc., scrubbing guts and hauling carcass remains after the real heroes save the day. This feels much more down-to-earth than a new protagonist born into the world with a gift/destiny etc.
His stagnant routine changes overnight when an ambitious young rookie named Reno Ichikawa joins his cleanup crew. Reno reignites Kafka’s long-dormant desire to join the Force. Just in time for a bizarre, parasitic mini-kaiju to force its way down Kafka’s throat. Suddenly, Kafka gains the ability to transform into an insanely powerful humanoid beast dubbed Kaiju No. 8. Now, he has to pass the grueling Defence Force selection exam, hide his monster secret from his own comrades, and protect humanity without getting executed by the very military he’s trying to join.
Why It Works
The 30-Something Protagonist
Shonen is flooded with teenage prodigies. Making Kafka an out-of-shape, millennial “has-been” struggling with back pain and broken dreams immediately sets the series apart. His journey hits differently because it’s a story about second chances and refusing to let life pass you by.
Kaiju No. 8, whilst set in a world of kaiju and super soldiers, still feels more real and relatable to someone more like me. Older, out of shape, working in a job that isn’t necessarily what I dreamed of. Accepting life for what it is.
Insane Production Value
Studio Khara’s creature and scale designs combined with Production I.G’s fluid, punchy animation create battles that feel incredibly heavy and devastating.
When Kaiju No. 8 throws a punch, the sound design and visual impact rattle your bones. It’s engaging and exciting to watch. I’ve been guilty of having anime on as background noise, but you can’t do that with Kaiju No. 8 it demands and rewards your attention.
Flawless Tonal Balance
The show smoothly transitions from terrifying, high-stakes military action to laugh-out-loud comedy. Kafka’s frantic attempts to act normal while his internal monster powers leak out are comic gold.
Not uncommon in anime, but not always quite so cleanly done. You feel more endeared to the characters because they feel more real, when the comedy kicks in. It’s never over the top and never just for the sake of it. Everything services a scene or interaction.
The Characters & Dynamics
The real soul of Kaiju No. 8 lies in its ensemble cast and the brilliant web of relationships connecting them.
At the centre is Kafka Hibino, the well-meaning, funny, and fiercely protective underdog. Rather than a typical prodigy, Kafka’s maturity, life experience, and sheer determination make him a natural leader, even as he struggles to hide his monstrous secret. His bond with Reno Ichikawa serves as the emotional anchor of the team.
Reno, a serious, talented, and driven rookie, starts off distant, but quickly becomes Kafka’s most loyal partner and confidant. Their relationship is a hilarious and touching dynamic of mentor-meets-babysitter, with Reno constantly acting as the straight man trying to keep Kafka’s secret identity under wraps.
Adding plenty of spark to the group is Kikoru Shinomiya, a battle-hardened prodigy wielding a giant axe and the daughter of the Defense Force Chief.
Though she begins as a classic tsundere who looks down on “the old guy,” she quickly grows to deeply respect Kafka’s courage and secret power, turning into one of his most vital allies on the battlefield.
Meanwhile, Kafka’s ultimate motivation stems from Mina Ashiro, the icy, legendary Captain of the Third Division who obliterates giant kaiju with a massive cannon. Bound by a childhood promise to fight side-by-side, the silent tension between Mina’s towering military status and Kafka’s secret underdog struggle creates a magnetic emotional core.
Rounding out the core cast is Soshiro Hoshina, the Third Division’s Vice-Captain whose lightning-fast dual-blade combat skills steal every scene he’s in. Sharp-witted and incredibly perceptive, Hoshina remains suspicious of Kafka from day one, creating a thrilling cat-and-mouse tension whenever the two share the screen.
Kaiju No. 8 knows how to deliver characters, and give them relationships. Complicated, as life often is, but not over-dramatic or forced.
The Agony of the Cliffhanger
Ending the latest season on such a massive, heart-stopping cliffhanger was pure torture! Just as the stakes hit an all-time high and the broader mystery of the intelligent, humanoid Kaiju began to unravel, the credits rolled. Just like Black Clover…..
Leaving Kafka’s identity, his place in the Defence Force, and the fate of the nation hanging in the balance makes the wait for the next installment almost unbearable. The lore is expanding rapidly, the battles are escalating to catastrophic levels, and we need to jump back into this world as soon as humanly possible.
If you’re on the lookout for a new anime, Kaiju No. 8 should be it. Honestly, it’s exceptional and everyone should watch it.
There’s more to come, and that’s great, but that just means a re-watch before the next season is released. Something I’m genuinely excited to do.
Do yourself a favour and give Kaiju No. 8 your full attention. It’s worth every second.
