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.

After turning into a Kaiju, Kafka is forced to flee. His escape is interrupted, however, by the arrival of another Kaiju...

Kafka is now a member of the Defense Force, if not a full-fledged one. But Hoshina tells him he has three months to prove himself before he's fired...

Reno and Iharu encounter a powerful humanoid Kaiju that quickly overwhelms them. Can help arrive in time?

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