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.

An unexpected incident during the exam forces Kafka to use his powers at the risk of revealing his secret.

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

Kafka's final fate is determined as the monster within him tries to take control.
