Honkai: Star Rail: The Kamen Rider Who Does Whatever He Wants

I open my eyes and go from being an anime-loving shut-in to a Kamen Rider, then transmigrate into my favorite world: Honkai: Star Rail.

Armed with a world driver no one has ever seen before, I can obtain the powers of game characters, other Riders, Armor Heroes, and even Ultraman. I can join the story as I please and change the script.

[No angst, no toxic elements, and the protagonist never gets humiliated. The author's first novel, written for fun, so please go easy on me. There will be an original Rider, similar to W. When the main story isn't updated, the protagonist may transmigrate across countless worlds.]
