Somewhere in the universe exists an unknown civilization known as "Chinzougun." This cosmic menace has been destroying countless planets, and among them, its officer Orneida has particularly targeted Earth. However, due to interference by the Motor Rangers, Orneida has repeatedly failed to destroy the planet, fueling his growing rage. Before him appears Goroiky, a brawler-like villain skilled in combat. Goroiky advises Orneida not to confront the Motor Rangers head-on, but instead to exploit their weaknesses. He proposes targeting Motor Pink—Yako Yaba. That day, Yako had sensed something ominous—the lace of her sneaker had snapped, and her horoscope on TV ranked dead last. Her premonition soon becomes reality. Attacked by Goroiky, cut off from her teammates, and abducted into another dimension, Yako Yaba's life plunges into the worst day imaginable.
