Kamen Rider: Who Gave General Fu's Script to E-Sama?

General Fu's reputation has hit rock bottom, and Keiwa has turned so dark he's lost his mind.

What would happen if characters from other Kamen Rider worlds entered the Geats world?

In the Build world, Sento, Ryuuga, Evolt, and the others stare at the words before them.

"Would you like to experience a new life?"

Sento: The Desire Grand Prix's technology? That's no challenge. I'll make you a few powerful ones.

Ryuuga: Michinaga, don't be so stingy. I think the Zombie Buckle and I are destined for each other. It's powerful, and it's a blast to use.

Evolt: The Desire Grand Prix? Faust, activate. The Goddess of Creation? What a waste, using something this good for this lousy competition. It's all mine.
