==Plot==
In 1972, Kotaro and his group hide the Creation King in the woods in revolt of Darom and the formation of the Gorgom Party. 
In the present day, Kotaro expresses his disdain for Heat Heaven to Aoi. Aoi's father Hideo Kawamoto is captured by Bilgenia and turned into a Kaijin. Nobuhiko continues to train his new recruits while he reminisces on an event 50 years ago. After a brief training session with Kotaro, Nobuhiko shared a kiss with Yukari. 
Igaki continues to spread his anti-Kaijin protests, but is driven away thanks to Shunsuke pooping on him. 
Hideo is then sent to Aoi, where he reveals his Kaijin nature to her and chases her. Kujira arrives and saves Aoi, but Hideo dies in the process. Though Kotaro discovers Hideo's Kaijin nature, he is ambushed by Nobuhiko, who wants to find Aoi for her Kingstone. Kotaro defeats Nobuhiko and catches up to Aoi with Kujira. He promises that he'll protect Aoi and brings her back to their bus so she can bury her father's Kaijin arm. 
Later, Aoi meets with Nick, who has information on the whereabouts of Rino Kawamoto, Aoi's mother. Shunsuke was nearby and secretly eavesdrops on their conversation.
