It could be about a character in the Inuyasha universe getting an opportunity to rewrite their destiny. Maybe Kagome finding a way to prevent some of the tragedies that occurred in the original story.
Kagome might be the main character. As she's from the modern world and has a big influence on the events in the feudal era, she could be the one who gets a chance to change the fates of everyone. For example, she could use her modern knowledge to change the course of battles or relationships in the story.
In this fanfiction, it could also be that a character has made a series of bad decisions in their life and then suddenly a strange event occurs. This event is their chance to change fate. It could be something like a time - travel incident that allows them to go back and correct their mistakes, thus altering the course of their life.
It's hard to say without actually reading the fanfiction. It could be the underdog character who is seeking a new start in life. Maybe it's a young adventurer who has been down on their luck and this chance to change fate is what sets them on a new path.
Let's say a character has a chance encounter with a hermit - like alien who has a unique knowledge of a powerful energy source. The character, out of curiosity, listens to the alien and starts to explore this energy source. This new knowledge and pursuit could lead the character to discover a new power for the Federation, making them a hero. But it could also attract enemies, so this chance encounter really alters the course of their life in many different and unpredictable ways.
I'm not sure specifically as I haven't read this particular fanfiction. It could be about a character getting an opportunity to transform their entire situation, whether it's in a fictional world like a fantasy realm or within a specific fictional universe like a TV show or movie that the fanfiction is based on.
It would completely disrupt the existing power balance. Their relationship would shift from one of rivalry to something extremely complex. It could also change how other characters interact with them, as this new situation would be so out of the ordinary.
In a fanfiction where Inuyasha is a girl, it would transform the story completely. Her appearance as a female would change the entire aesthetic of the series. She would probably have different clothing styles that are more feminine, which could also affect her movement and fighting style. Her relationships with the villagers would be different too. They might be more distrustful at first because she's a female demon, or they could be more sympathetic. Her character development would also be distinct. She might struggle more with issues like being accepted as a strong female in a male - dominated world of demons, and this could add a whole new layer of depth to the story.
In 'Naruto Chance to Change Fanfiction', a storyline could involve Naruto having the chance to change his relationship with Sasuke. He might be able to stop Sasuke from leaving the village in the first place. This would then change the entire dynamic of their rivalry and friendship. Also, he could use this chance to change how the Akatsuki is formed or dealt with, perhaps by finding a way to reform some of its members.
His relationship with other demons could be affected too. They might see his tail as a sign of his strength or weakness. Some demons might be envious of his tail if it has special powers. Others might try to use it against him in battles or to gain some advantage over him. It could also be a way for Inuyasha to bond with other half - demons who also have unique physical features like a tail.
