The Den-O story had ended, and Sakurai's brother-in-law, who should have disappeared, returned to the world and hijacked the Zero Liner, taking Ryotaro with him. The entire Den-O cast gave chase, only for both sides to fall into ■■'s twisted game.
When they woke again, what they saw was: the Destruction's Voidrangers, the Propagation's Swarm, the Hunt's arrows of light, the Harmony's songs, the Trailblaze's lights...
To get Ryotaro back, everyone set off on a journey aboard the DenLiner, which had lost its ability to travel through time, only to discover... What's with this “Aeon”? What's with this “devil”? And what's with this Paraji! Are we even filming in the same studio?
I transmigrated too? Well, in that case, never mind.
