Ultraman: I Draw Rider Skills and Become Invincible

Are There Stories Where the Protagonist Becomes a Brand-New Ultraman Instead of an Existing One?

I mean stories where the protagonist becomes a brand-new Ultraman, not transmigrates into an old one like Tiga, Cosmos, or Zero, and not one of those especially powerful Ultramen either. A completely new one.

No Kamen Rider, No Entry

Looking for books similar to Armored Warrior: The Campus Belle Stole My Trickster Driver from the Start. Are there any stories where someone transmigrates into a world without Kamen Rider, becomes an armored warrior, builds a driver, and shows off? No Ultraman, Armor Heroes, or Ben 10. I only want Kamen Rider, with no other franchises mixed in.

Kamen Rider in a Modern City, Not the Kamen Rider World, Just an Ordinary City

Any Stories with the Original Aotian? Please, I’m Begging for the Original Aotian!!! A Fake Transmigration Story Is Fine Too!!!

I'd like to read books similar to In Ultraman, I'm Just a Meat-Shield Support. The true form must be Ultraman Saga!! Please, I want one with a native of the original world! Preferably the type where Ultraman Saga's true form transmigrates into other worlds. There are so few books like this!

Looking for Kamen Rider Decade, Zi-O, Zero-One, W, and Gaim Stories

Please recommend some great books.
