Meanwhile, back in the Oizumi area where Kafka is, six supergiant-class kaiju emerge, worsening an already grave situation. But just as things get dire, some unexpected backup arrives!

The Defense Force has taken Kafka into custody and plans to dispose of him. To save himself, Kafka attempts to plead his humanity to Director General Shinomiya, wielder of the mighty Kaiju No. 2's power and the person lauded as the strongest in Defense Force history. When Kafka's pleas fail to move the director general, he winds up facing him in combat! Can Kafka keep his kaiju form together long enough to save his own skin? For teen audiences.

Can Kafka withstand his superior officer's attacks without revealing his true identity?! For teen audiences.

The raid on the Defense Force's Tachikawa base continues as the officers expend their efforts to fend off the yoju. Meanwhile, Hoshina unleashes his full combat power and takes on the daikaiju-the mightiest kaiju of the group. Just when the battle seems to be over, the daikaiju transforms and Kafka's detection ability reacts to it! Will Kafka make it in time to save the day?! For teen audiences.

When the final test of the Defense Force screening exam ends, a mysterious humanoid kaiju revives a neutralized honju and sics it on Kikoru Shinomiya and the rest of the examinees.
