en Cuevana 3. An animated short shown with Farewell Kamen Rider Den-O: Final Countdown. In the short, Momotaros feels bad that it is really the end of Kamen Rider Den-O as Urataros assures him that all good stories have to end sometime. After Kintaros and Ryutaros try to make sequels to classic stories that cannot have a sequel (A Dog of Flanders and Little-Match Girl), the Imagin end up on the moon in homage to Galaxy Express 999, embracing their final story. A later retelling of this short, Be Forever Momotaros: Imagin Terminal Station, provides an alternate ending where the story does continue with numerous new characters and Momotaros freaks out about it.
