In Zero-One, I Became Kamen Rider Build from the Start

Chen Xing transmigrates into the world of Kamen Rider Zero-One, gains Kiryu Sento's talents, and even acquires the power of Kamen Rider Build.

The Spider Fullbottle, Rabbit-Tank, Genius Form... And that's not all: he gains the powers of other Riders, including Zi-O and Decade... He brings every power together in himself.

From then on, Chen Xing leaves behind an invincible legend across countless Kamen Rider worlds.

Yua Yaiba is my wife, and so is Izu...

Zero-One: Senior Chen Xing is my idol. I'll make him my goal.

24-Year-Old: That Chen Xing guy is a wrench in my plans. His strength is far beyond mine.

Chen Xing: "Come on, transform! I am Oma Zi-O!"
