Well, Boruto might be really shocked. He has seen Naruto in his normal state, but seeing Naruto in the 4 - tails form through a fanfiction would be wild. He might be amazed at the power his father once had to control such a powerful and wild form. He could also start to understand more about Naruto's past struggles.
Konoha could feel a sense of wonder. Since fanfiction can be very creative, the Naruto openings in it might be full of unexpected twists and turns that make Konoha wonder about all the possibilities within the Naruto universe.
He'd probably be a bit of shocked. Since fanfiction often contains things that are quite different from what he knows. For example, if it shows a different future for his friends, it would be unexpected for him.
First, approach it with an open mind. Don't expect it to be exactly like the original Naruto series. Fanfiction is all about creativity and exploring new ideas.
A vivid description can also make a great novel opening. Such as 'The sun blazed down on the dusty town, the heat rising in shimmering waves from the cracked streets. The saloon doors swung open, and a figure emerged, his face hidden beneath a wide - brimmed hat.' This type of opening sets the scene and makes the reader curious about what will happen next. It gives a sense of place and a hint of mystery.
Beginning with a vivid description can be great. Like in 'The Great Gatsby' where it starts with 'In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since.' It gives a sense of the narrator's voice and draws you into their world.
One of the best openings is from 'Pride and Prejudice' by Jane Austen: 'It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.' This line immediately sets the tone for the story which is centered around marriage and social status in 19th - century England.
One great opening is to start with a thought - provoking question. For example, 'Have you ever wondered what it would be like to live in a world without colors?' This immediately grabs the reader's attention and makes them curious to find out more. It sets the tone for a story that could be about a world where something fundamental has been altered.
