Japan has the highest rate of monster emergence worldwide; these monsters are also known, and you can expect to see them quite often in the streets or anywhere where there is a pile of humans.

In Japan, Yokohama has the highest rate of emergence in the country. Still, luckily they have the Anti-Kaiju squad always nearby, and over the years, they have been very successful in neutralizing them.

The story’s main character is Kafka Hibino, a 32-year-old single man working in the cleaning or the aftermath sector in the field. His duty mainly includes cleaning up the mess Kaiju’s and Anti-Kaiju’s squad created.

One day as he was cleaning a Kaiju intestines, a team member mistakenly used the wrong machine, resulting in the blast of the intestine, and the blood got spilled everywhere; this type of occurrence was pretty common at the time.

He was completely unaware that this event would change the whole trajectory of his life and fill it with many challenging obstacles.


The most vital member of the Anti-Kaiju squad was Mina Ashiro, a childhood friend of Kafka; however, they both took very different decisions, resulting in a total gap between the two.

Kafka ended up in the cleaning department, whereas Mina became the captain of the 3rd division defense force; Mina quickly rose the rank due to her abilities and has never looked back ever since.

The next day Kafka meets Reno Ichikawa, a recruit who dreams of joining Mina in the defense department; however, he is also very arrogant and does not like to take no for an answer, due to which he has no friends.

Reno asks Kafka why he gave up on his dream; during the conversation, he tries his best to avoid answering it, but Reno keeps bugging him about it, bringing back painful memories.

During their work, Reno observes him very closely and deducts that he is a nice person who doesn’t have the guts to change jobs, but deep down, he is a very sincere, loyal, and hard worker.

As they had an excellent movement together, suddenly, out of nowhere, a Kaiju emerges, and Kafka saves Reno in the last moment, but it is not enough. Luckily, Mina was nearby and rescued them both.


After getting saved, they both rested in the infirmary, where Reno convinces Kafka to enter the exam for joining the defense force as the age for admission has increased from 32 to 33.

This means Kafka has one more chance of succeeding and completing his promise to Mina as a child that he would always fight side by side with her and eradicate all the Kaiju from the world.

Suddenly a Kaiju emerges out of thin air and enters his mouth, turning him into a Kaiju; freaked out by his sudden change in the body, he causes a commotion and runs away from the hospital.

While he is escaping, Reno also joins him; as they are escaping, they sense a Kaiju who is about to kill a little girl, and that’s when Kafka saves her, but this results in him becoming a target for the defense forces who have started searching for him.
