Kamen Rider Den-O: I'm Born!

Ryotaro pursues the Molech Imagin to May 8, 2000. Though Den-O Sword Form destroys the Molech Imagin, the Imagin fulfilled his mission as the DenLiner ends up hijacked by the rest of the Imagin led by a rogue Kamen Rider named Gaoh. After stealing Owner's Master Pass and trapping Urataros and Kintaros, Gaoh forces the DenLiner to travel back in time via "God's Line" to the Edo Period of Japan so he can retrieve the legendary God's Train, the GaohLiner.
