Yomogi and Yume visit the city where they fought the Kaiju and witness the tragedy. He and the others start their Dynazenon maneuver training, but a Kaiju appears again without any delay.

At Chise's suggestion, Yomogi and his friends go to a large outdoor pool, but there is unexpected company there. Gauma orders Yomogi and Yumemi to pretend to be lovers for a certain mission.

Dynazenon is defeated by the Kaiju. A mysterious giant that appears. Despite the confusion, Onija and Mujina begin to fight the giant. Gauma has no way to repair the damaged Dynazenon.

Yomogi and Yume hear about how Kano died. A Kaiju suddenly appears without them being able to take in the story. Meanwhile, Chise holds onto a secret.

Yomogi and the others begin to resume their everyday life, and the Kaiju Eugenicists who have lost their Kaiju also lose their place in the world.
