Well, there are also those characters who might be a bit shocked or confused. Take Levi from Attack on Titan. He's a very serious and no - nonsense type of character. If he were to read some of the fanfic about him that deviated too much from his own self - perception, like being made into a comical or overly emotional character in the fanfic, he might be taken aback at first. But then he might also realize it's just a different interpretation and not take it too seriously.
Well, it depends on the nature of the fanfiction. Some anime characters might be amused if the fanfiction is light - hearted and full of comical situations. For example, if it's a fanfic about a cooking competition among the characters from a shonen anime, they might react with good - natured laughter and competitiveness. They could also be confused if the fanfiction takes their story in a very strange or unexpected direction, like suddenly making a character from a historical anime end up in a space adventure.
One popular 'anime spiral fanfiction' story could be about a character from a well - known anime getting caught in a time - spiral adventure. For example, in a Naruto - based fanfiction, Naruto might be sent through a spiral - like portal that takes him to different dimensions where he has to face new and strange versions of his enemies. Another could be from the One Piece universe, where Luffy and his crew enter a mysterious spiral - shaped island with its own unique rules and challenges.
First, decide on the anime you want to base your fanfiction on. If it's an action - packed anime like My Hero Academia, think about how a spiral concept can be introduced. It could be a new villain's quirk that creates spiral - shaped attacks or portals. Then, create your main character's role in this spiral - filled world. Maybe they are the only one who can stop the spirals from causing chaos.
Kakashi would be very observant. He would look for how the fanfiction writers understand the world of Naruto, the values and the moral lessons. He might even use some of the creative ideas from the fanfiction in his own teachings if he thought they were valuable and in line with the spirit of the original story.
There could be characters who are outraged. If the fanfiction distorts their personality or makes them do things completely against their nature, they may be very angry. For example, a noble character made to act like a coward in the fanfiction would likely not take it well.
They might be confused at first. RWBY has its own unique lore and concepts that are different from many anime. So anime characters may need time to understand things like Grimm and Huntsmen. For example, if Goku from Dragon Ball was watching, he'd probably be like 'What are these strange monsters?'.
They could be surprised. The fanfiction might show them in scenarios they never imagined, like a shy character being in a very bold and adventurous situation.
Since we don't have much information about this 'time spiral novel', the main characters could be ordinary people who get caught up in the time - spiraling events. They might start off as normal individuals living their regular lives, but then as the time - spiral begins to affect their world, they develop unique abilities or characteristics related to dealing with time. For example, one character could be able to remember fragments of different time loops, which helps them try to break free from the spiral or understand it better.
I don't know for sure since I haven't read it. But typically in such a novel, there might be a curious protagonist who is drawn to the spiral staircase, perhaps a young person full of inquisitiveness.
