Black Tide Island: Becoming Galaxy Ultraman from the Start

He transmigrates into the world of Ultraman, but something seems to have gone wrong with the way he got there.

Ultraman King turns out to be a fusion warrior with Arus at its core.

Reiblood had already chosen his successor, so why hold the Leo*X Battle?

If Gaia represents the light of Earth, could there also be a light representing Alaya?

Are humans and Ultraman undergoing super-evolution, or reverting to their ancestors?

What was the purpose of the end of the ancient civilization, and who rekindled the spark of hope three million years later?

Light is a bond. I will keep passing it on, all the way into the future!

P.S. This is a new writer's work, and I'm not very good at writing blurbs. Since this is a fanfic, I changed the title to English.

This novel and its characters are entirely fictional. Any resemblance to real people or events is purely coincidental. Do not imitate.
