Ultraman: Getting the Original Ultraman from the Start

Any Good Ultraman Fanfiction on Tomato Novel? I’m Desperate for Something to Read

Looking for books similar to *[Ultraman Crossover] Belial: My Human Host Has Stopped Acting Human*. The protagonist can be male or female. What matters is that the characters are smart and have sound values. Above all, I don't want anything pairing people with the Mother of Ultra or Father of Ultra. Absolutely not, that really squicks me out. Good writing, too.
