As a Kamen Rider, I Was Forced to Become Light

From the start, he gets the King of Arthur and the Ten Blades of Seiken Saber

Jiang Cheng was just about to walk onto the Kamen Rider set when the System accidentally teleported him to the Ultraman universe.

Jiang Cheng: System, where is this?

System: “Don't panic, Host. I'll grant you the skill to craft Wonder Ride Books by hand...”

As two monsters rush over to tear the place apart, Jiang Cheng, now holding the Tiga Wonder Ride Book, suddenly breaks into a terrifyingly warm smile. From then on, the Ultraman universe gains another “Evil Sword Immortal,” wandering around with a sword and collecting Wonder Ride Books.

Reboot + Kamen Rider + Ultra Warriors + System heroine + a street loafer who keeps switching sides

(This is a reboot, so some plot points may not line up from time to time, or some strange content may be added. Please bear with me.)

(I'm a coward.)
