Kaijuu 8-gou

As children, Kafka Hibino and Mina Ashiro promised they would join the Defense Force together and protect Japan from kaiju. Decades later, Mina is a celebrated captain while 32-year-old Kafka cleans monster remains after battles and has almost surrendered the dream they once shared.

His younger coworker Reno Ichikawa pushes him to try again, but a bizarre incident changes everything: a small creature enters Kafka’s body and gives him the ability to transform into an immensely powerful humanoid kaiju, which the Defense Force labels “Kaiju No. 8.” Kafka now has to pass the tests that defeated him before while hiding a secret that makes the very organization he wants to join see him as a monster to be eliminated.
