Kamen Rider: The Whole World Knows I’m the Demon King!

(Impure World Reincarnation: Missing for Five Years, I Returned as the Monster King)

My name is Bai Ye, and I transmigrated here. My only dream is to find my long-lost sister in this world where Kamen Rider is real, then lie flat. Until one day, everyone in the world heard that voice:

[Announcement: Bai Ye is destined to become either the Darkest Demon King who destroys the world or the Ultimate Hero who saves it all.]

Overnight, I went from a tokusatsu fan who just wanted to take it easy to the “Future Demon King” the entire world wanted to study, control, or hunt down.

The Dragon Kingdom’s Kamen Rider Academy wants to imprison me for observation, viewing me as the most unstable “Omega-level anomaly.” The monsters lurking in the shadows see me as a rival who must be eliminated, or a perfect pawn to exploit.

Fortunately, the memories from my previous life are my greatest cheat. I know every Rider’s weakness and every monster’s origins inside out. The blank Ridewatch in my hand, capable of holding the history of every Rider, and my fanatical servant, who keeps wanting to “celebrate me,” are my only means of flipping the board.

Gathering the power of the nineteen main Heisei Riders will earn me the right to ascend the throne.

But I have only one goal: before I become the true “King,” find the man who calls himself the “World Destroyer” and ask him where my sister is!

My enemies think they control the script, never realizing I’m the only one who knows all the spoilers.

So here’s the question:

When a “Demon King” who knows every plot point steps into the story himself as the “protagonist,” just how interesting will this world become?
