In Beika Town, Building a Beauty Knight Order

Transmigrating into a world of anime crossovers.

Yagyu gains a golden finger: the power of Creation.

On the surface, he's an utterly ordinary high school student, except for being incredibly handsome.

But behind the scenes,

he is the ruler of a world!

Using the power of Creation, he opens up a Mirror World and creates Kamen Rider transformation devices.

Everything changes without anyone noticing.

One day,

Ran "finds" a transformation device and becomes a Kamen Rider.

The Cat's Eye trio "steal" transformation devices and become Kamen Riders.

Yako "seizes" a transformation device from a criminal and becomes a Kamen Rider.

Yagyu, the "mastermind" behind the scenes, orchestrates it all.

He thought this was an ordinary slice-of-life anime.

Until one day, all kinds of monsters invade...

Yagyu steps forward.

Behind him stands a group of valiant, beautiful Kamen Riders!
