While going out for takoyaki on Gai's suggestion, the Goukai Galleon crew find the owner, Nobuyuki, with Jerashid whom the five senior crew recognize and attempt to leave so not to get involved. However, Gai convinces them to stay to see how it unfolds. Elsewhere, after giving a dull presentation that puts Warz Gill to sleep, the Action Commander Sen-den has the Gormin litter the town with Zangyack propaganda posters before finding Jerashid. Learning that the alien has become a human's pet, Sen-den attacks Jerashid and Nobuyuki for their defacing of Zangyack superiority. Reluctantly deciding to meddle in the conflict, the Gokaigers use the powers of the Megarangers to waste the Gormin and then assume the forms of the Hurricanegers, Gouraigers and Shurikenger to fight Sen-den. However, Sen-den escapes back to the Gigant Horse, temporarily under Damarasu's command, and asks to borrow a weapon, as his propaganda strategy has failed. Later, after Gai has Nobuyuki apologize to Jerashid for treating him like a pet, Doc suggests that Jerashid should be the man's apprentice instead. Seeing a potential in selling takoyaki in space, Jerashid agrees. However, Nobuyuki's mother has the final word and she disapproves out of health-based prejudices against aliens and to preserve earth culture. By then, Sen-den and his troops barge in, only to be forced on standby until learning from Jerashid that Nobuyuki's mother called him "natural waste", going on a shooting spree with the Zangyack Bazooka. Taking the fight to a nearby construction yard, the Gokaigers fight Sen-den after having Jerashid and the humans hide inside concrete pipes. But when Nobuyuki's mother runs out of the pipes to avoid heatstroke, she unknowingly become Sen-den's target as Jerashid takes the blow meant for her. Pretending to die just to be cool, Jerashid manages to convince the mother that not all aliens are evil before getting her and Nobuyuki to safety. The Gokaigers then use the power of the Timerangers execute Vector End: Beat Defender to destroy the Zangyack Bazooka before defeating Sen-den with a Gokai Legendream/Gokai Scramble combo. After Damarasu fires the enlargement cannons on Sen-den, the Action Commander overwhelms Gokaioh and Goujyu Rex until Gao Lion is summoned. Soon after, Shinken Gokaioh and Goujyujin finish Sen-den off with their respective signature attacks. After the fight, the Gokai Galleon crew learn from Nobuyuki that his mother and Jerashid have eloped and were last heard running a rural onsen with a baby on the way.
