The protagonist is a huge fan of Ultraman Tiga. One night, he gets so excited at the sight of Tiga that, for reasons unknown, he transmigrates to Tiga’s world while asleep.
At first, he helps Daigu in the world of Tiga.
Later, he’ll visit other worlds, some with Ultraman and some without.
Because of his special circumstances, the protagonist will eventually become light himself, but he’ll be pretty weak, since he’s just an ordinary person.
He’ll meet all sorts of people and make plenty of friends.
Tiga and Dyna will feature more heavily at the beginning and less later on, but they’ll still return.
For most of the later story, Jiang Daoli will travel alone, possessing human bodies.
A universe without Ultraman
The overall outline is okay, but there are many details in the article that I can't dig into because they don't match the original plot. The transitions between chapters are not natural and a bit stiff. I don't know why the whole book gave me a feeling of AI. The Dagu in the article also feels weird.
The subject matter and outline are quite good, but the writing style is not very good and it feels like a running account.
