[Kamen Rider ZZZ + Mild Horror + Body Horror + Infinite Flow + Emotional Focus + Pseudo-Dark] A group of people from other bizarre worlds are loaded onto a death train, including someone who possesses the power of Kamen Rider ZZZ.
Outside, cities are made entirely of flesh, and there are more demons within them than anyone could count.
Everyone has their own Zez ZZZ Driver.
At regular intervals, the train stops and sends everyone into a bizarre, absurd world to take on the role of an agent. They can only return to the train after completing the mission there and bringing back the chosen one.
To leave this hellish place, they must keep the train moving along this eerie road, pressing ever onward until they reach the end of the world.
After journey upon journey, they form deep bonds with those chosen ones. Who, exactly, is the one controlling these countless bizarre worlds?
What is their true purpose?
At the end of this world, will they find despair or hope?
