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?

After transforming into a Kaiju to rescue Reno and Iharu, Kafka is found by Hoshina, who immediately attacks him.

Kaiju No. 8 is captured, and Kafka is at the mercy of the Defense Force's most important leaders.
