📖 Story: What is Kaiju No. 8 About?

Set in a future Japan constantly attacked by terrifying monsters called Kaiju, the country’s Defense Force works tirelessly to eliminate these threats. The story follows Kafka Hibino, a 32-year-old man who once dreamed of joining the force but ended up working as a kaiju cleaner instead — someone who disposes of the corpses after battles.

Everything changes when Kafka is infected by a mysterious kaiju and gains the ability to transform into one himself — earning the nickname “Kaiju No. 8.” Now, with power beyond human limits, he re-enters the Defense Force not just to protect humanity, but to uncover the mystery behind the kaiju itself.
