OOO and Fouze manages to corner Gara, but she transforms into her complete form. Creates a space Yummy, Fouze and the Yummy goes out to space.

The story starts with an accident at Gentaro Kisaragi's school, Amanogawa Academy. Amanogawa can be translated as milky way.
Gentaro is somewhat of an deliquent, thus the other classmates tends to not socialize with him.

The producer is Tsukada. The writers are Riku Sanjo and someone experienced with Sentai but have never written for Kamen Rider.
