Grotesque, Godzilla-like monsters called "kaijuu" have been appearing around Japan for many years. To combat these beasts, an elite military unit known as the Defense Corps risks their lives daily to protect civilians. Once a creature is killed, "sweepers"—working under the Professional Kaijuu Cleaner Corporation—are left to dispose of its remains.

Kafka Hibino, a 32-year-old man, is unsatisfied with his job as a sweeper. From a young age, he has aspired to join the Defense Corps and kill kaijuus for a living. After a few failed attempts, however, he gave up on his dreams and resigned himself to the mediocrity that provided a decent paycheck. Nevertheless, when an ambitious, 18-year-old recruit named Leno Ichikawa joins his cleaning team, Kafka is once again reminded of his desire to join the military.

Following a chain of unfortunate events and an interaction with the junior sweeper, Kafka encounters a parasite-type kaijuu that forces its way in through his mouth—turning him into a humanoid monster. With his newfound powers, Kafka aims to give his lifelong dream a final try.

Preliminary (3/? eps)
Ok, so I've read the first 3 chapters (The only chapters out now)

I must say it's really nice and looks really promising

Ok, so the mc made a promise with this girl when they were children to kill all kaijus (monsters) so they tried joining the defense corps.
But the mc was kind of weak and he ended up with a job to clean up the corpses of the monsters after the defense corps kill them.
He gets new powers one day to turn into a monster.

Ok, this manga has action and comedy, and was fun to read. The comedy is especially nice.
Do I recommend this manga? Sure, ...

Mixed Feelings
Preliminary (13/? eps)
As of right now there are 13 chapters. It started pretty strong (I'd say an 8), but over time I just can't help but feel nothing is happening, at all.
Sure, there was a fight, an exam and a little twist and mistery, but the dialogue is so empty and the characters so... bland. I can't help but feel like I've seen all of them before, and done better.

I'll keep reading for now, but the only kind of strong point is the art, because the story started ok but now is a solid 6, and the characters aren't much better except for the MC who's a ...

Preliminary (54/? eps)
I think Kaiju No8 started off on a strong note cause of the initial premise. The world in Kaiju no8 is a world ravaged by Kaiju and humans formed the Japanese Defense Force, a military group that specializes in killing monsters. Our MC is a middle-aged man who works as a Janitor who cleans up after each monster is killed, but in reality, he longs to join his childhood friend who works as one of the strongest fighters in the Japanese Defense Force.

Kaiju no8 is not breaking new grounds or anything cause once you boil it down, it's pretty much a generic shonen manga. ...
