After the destruction of their hometown, childhood friends Kafka Hibino and Mina Ashiro make a pact to become officers in the Defense Force—a militarized organization tasked with protecting Japan from colossal monsters known as "kaijuu." Decades later, the 32-year-old Kafka has all but given up on his dreams of heroism. Instead, he cleans up the remains of the slaughtered kaijuu after they are defeated by valiant soldiers—including Mina, who has successfully achieved their shared goal.

Upon meeting his new coworker, Reno Ichikawa, Kafka faces a mirror of his past self: an ambitious young man whose one desire is to fight as a member of the Defense Force. Unfortunately, the two are soon involved in a freak encounter with a rogue kaijuu. Though Kafka demonstrates his innate heroic nature and rescues Reno from certain doom, he is left gravely injured.

While both men recover in a hospital, Kafka is seemingly attacked by another one of the beasts. As a result, he gains the ability to transform into a humanoid kaijuu with the strength and powers of the massive monsters menacing Japan. Dubbed "Kaijuu No. 8" by the military, Kafka resolves to use his newfound gifts for the greater good. Tied together by mutual respect, Kafka and Reno set out to join warriors like Mina at the forefront of the Defense Force.

Preliminary (3/12 eps)
I'll say it season after season. But when silliness hits well, it hits hard.

Kaijuu on paper looks like the kind of show, that will fill your action serious bubble, and more so. But when you actually watch it, there is more to it. Given it's fun, and comedic reactions. It kinda gives me Little Witch Academia vibes in that sense. Having a serious idea, a serious setting. But go at it with a mix of that tone of seriousness, and general fun. A mixture of styles and tones, that'll carry the series through out.

Where it gives me same vibes too with LWA ...

Mixed Feelings
Preliminary (3/12 eps)
Man, after so much promise in the beginning the growing number of red flags is becoming concerning for me. Hopefully things turn around going forward because I really enjoyed the premise that was set up initially. Unfortunately, reading the reviews for the manga has left me feeling uneasy for what is yet to come.

The biggest red flag for me is Kafka potentially devolving into a stereotypical middle school male shounen MC with all of his yelling. Part of my interest in his character was seeing a middle aged guy get a 2nd chance at his dream after giving up. If he continues acting too ...

Preliminary (3/12 eps)
This series is not about Kaijus, seriously, if you are a kaiju fan, turn around, this is My Hero Academy with 2000's shounen paint.

0 characterization, Kafka is your cringe shouty shounen protagonist whose age is only relevant to make jokes about, otherwise he's a manchild that acts exatly like Asta, Midoriya, etc... I hit 30 recently and low key fell offended lmfao; Sidekick is... Just the sidekick, there's also Bakugo with pink hair, the snobby blonde rich girl, the cold strong dude that doesn't talk much, confident chill guy, childhood friend love interest that's mc's goal to defeat and has the personality of a wet ...
