Kafka Hibino has almost abandoned his dream of joining the anti-Kaiju "Defense Force." He now works in Kaiju clean-up, disposing of the bodies of slain Kaiju and thinking back with regret to the days he spent with his childhood friend Mina Ashiro, captain of Defense Force's Third Division.

Kafka arrives for one last shot at the Defense Force entry exam... but can he pass while keeping his Kaiju powers a secret?

When the Defense Force is in danger, Kafka is forced to choose between keeping his secret and saving his comrades.
