National Fate: A Nightmare Descends from the Start! I Am ZZZ

[Kamen Rider + Calamity King + Another World + School Beauty + Secret Agent]

Meng Yan transmigrates by accident into a world being ravaged by nightmares.

Here, people dare not sleep carelessly. If they fail to take precautions, nightmares will take their place.

Just then, the talent Meng Yan awakens is the nightmares' strictest father: Kamen Rider Zeztz.

Nightmares: “Great, it's the Calamity King. We're done for!”

The Three-Star Impact King is still way too overpowered. We should use the Two-Star Calamity King instead.

And just like that, Meng Yan becomes the nightmares' nightmare.
