While the rookie members demonstrate the results of their training and manage to suppress the pterosaur monsters, the attack of the giant "Kaiju No. 10" intensifies even more! Hoshina continues to attack steadily in response to changes in the enemy, but finally reaches its limit. At that moment, what came to Hoshina's mind were Mina's words, who recognized her swordsmanship and entrusted her with her back.

While the members of Unit 3 are scrambling to save Kafka's life, a deadly battle between Kaiju No. 8 and Isao continues at the Ariake Rinkai base. Gong, who can freely manipulate the power of the giant monster, fully demonstrates his ability, which was once touted as the strongest in the history of the Defense Corps, but the monster No. 8, which has lost control of Kafka and has gone out of control, fights back with an attack that does not care about physical damage. A ruthless attack hunts down Gong.
