Synopsis

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 Reno 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.

A great shonen series with a fun cast of supporting characters, a cool conceit, and absolutely massive scale! Now that the whole series is over, I can recommend it to anyone who reads shonen, the biggest point against it was the s l o w pace of chapter releases. Once I saw that it was likely in 'final battle' territory I stopped reading, after learning from My Hero Academia that a final battle spread over more than a year is... tough to follow. I made the right choice - being able to read from the start of the invasion to the last chapter was an ...

Mixed Feelings
It has finally ended, an extremely hyped manga, with high demand for anime and the creation of a seemingly cash-grab gacha game, i haven't checked the stats on that but it did happen and I hope the people who played are getting their time's worth.
From the beginning, I felt this manga was special, a semi-dead ended protagonist, on the older side, with a possibility to contribute to society in the body of a kaiju, the very enemy of the series.... it's pretty good!!! If you require depth... or more wold building? I think the way the creator of the series found a solid output ...

Fantastic premise, setting, characters and world-building. The very beginning is fantastic and leaves you hooked, with a protagonist that isn't just a chosen one archetype being recycled. None of the other characters are overly stereotypical either; they all might fit in archetypes but they're fleshed out into their own things.... And the constant themes put forward in the story about breaking the norm and having to reinvent yourself to move forward were so refreshingly unorthodox that it only makes it the more frustrating that it copped out with the most recycled cliché there is.

I cannot say it's a bad story, because it objectively isn't, but ...
