A Shenshan Bookshop from the Start: Cursing the Old Geezer Oma Zio!

[Apocalyptic parallel universe]+ [The entire main cast gets lead Rider treatment]+ [Rewriting the four Reiwa Riders]+ [After endless darkness, love and peace are sure to come]

(The story followed the plot for a while, but the author has recognized the issues and will go wild with original ideas from here on.)

Kamen Riders are supposed to bring people hope and warmth.

Ninety-nine percent of this planet is occupied by monsters. Humanity lives in crowded cities like livestock penned up in a cage, numb to their existence, while the monsters torment them at will. Their lives are unbearable!

The King of Time sits upon the throne of Dai-Shocker.

The king from eight hundred years ago was never sealed away for his boundless ambition. He rules unchallenged...

A black warrior from the super-ancient era, whose pitch-black eyes endlessly devour all light...

Black cards fly out of an Aurora Curtain that appeared from thin air...

And just beyond the planet, a pure golden world hangs within arm’s reach...

The darker the place, the brighter the light shines!

This is the story of those who struggle to find hope in despair.

This is the story of rebels who give their lives for hope.

A Unifier of All Things who enters the story of Revice but refuses to use Vistamps?

A musclebound idiot who’s an orthopedic surgeon and loves fighting games?

A Fool who gathers Sequence materials with tarot cards in a book world?

A black monster who longs for happiness, yet sees pain as the only thing worth seeking?

A ridiculously powerful member of the King-Ohger team who believes everyone should be equal...
