Master of Forbidden Arts in Ultraman Tiga

The male protagonist travels to the world of Ultraman Tiga and obtains the AllSpark. However, due to the time travel, its power can only be used three times before needing to be recharged. Furthermore, the knowledge within it is sealed away as the AllSpark's power dissipates. He needs to replenish his power to access it again.

What's going on in the recent chapters? What is the protagonist's role? What's the point of spending so much time describing Ultraman Tiga?

So after reading so many chapters, I still don't know which Ultraman the main character is?! ԅ(¯ㅂ¯ԅ)

After reading three chapters, I'd like to ask if the rest of the story was copied entirely from the Ultraman Tiga TV series? Is the main character the kind who is dispensable, whose presence or absence doesn't matter?

Ladies and gentlemen, I have written a book about Ace.

I'd rather rewatch the Ultraman Tiga TV series than read this novel.

So, after reading twenty or thirty chapters, what's the protagonist's Ultraman name? And why does the protagonist have so little screen time?

I'm too used to following the plot. 😐 It would be so much better to write something original of my own.

You might as well just become the director of a meat processing plant.

What's the connection between nuclear wastewater and Ultraman? Why is the system recommending this to me? 🙂🙂
