Story

As Misae hurries to prepare Shin-chan for his bus ride, he suddenly finds himself aboard the DenLiner, materializing on Ryotaro’s face. The group is intrigued by Shin-chan’s arrival, especially Hana and Naomi. Meanwhile, back at home, Misae faces difficulties as the Fatmass Imagin attempts to fulfill her wish of getting Shin-chan to the bus on time.

Hana suspects involvement from an Imagin—misheard by Shin-chan as —which includes Momotaros, whom Shin-chan amusingly calls a red Buriburizaemon. When Ryotaro transforms into Kamen Rider Den-O Sword Form to confront the hostile Imagin, Shin-chan unexpectedly becomes Kamen Rider Shin-O to assist him. The Fatmass Imagin launches an attack but is ultimately defeated after Shin-O fuses its three fat masses together. The Imagin tries to erase any instance of Shin-chan arriving punctually but finds none.

Den-O eliminates the Fatmass Imagin, rescuing both Shin-chan and Misae who miss their bus. Recognizing Shin-chan’s contribution to preserving the timeline, the Owner grants them permission to travel back just moments before the bus arrives. As they part ways, Shin-chan still needs to use the restroom but ends up soiling himself in his rush—coinciding with the bus’s arrival.
