Surviving the Go-onger's and Go-on Wings' attacks with his Bottomless Wastebin, Kireizky uses it to send them all off to separate directions so he can begin his sweeping of the Human World. Sōsuke, Gunpei, and Renn find themselves in a kindergarten being held hostage by bank robbers, with the three Go-ongers catching the crooks off guard and making a citizen's arrest before making their way to Tokyo Tower to stop Kireizky and blast his waste bin away. However, Kireizky swallows the Dokkirium he gathered from the previous worlds he cleaned to Super Industrial Revolutionize as Kyoretsu-Oh forms to fight him with Bus-on and Gunpherd supporting him. While this occurs, Hiroto and Saki were in a haunted graveyard and are terrorized by ghosts until Saki gives Hiroto the courage to overcome his childhood fear, only to learn that the ghosts they beat up are actually amusement park workers. The two arrive in Bearrv and Toripter, forming Engine-Oh and GunBir-Oh Toripter. Meanwhile, Hant and Miu help Santa find his Different-Dimension Present Bag, which was mistaken for a garbage bag by garbage men who take it to be incinerated.
