One possible fanfiction could be about Inuyasha and Sango going on a quest together. They might face a powerful demon that requires both of their skills to defeat. Inuyasha's brute strength combined with Sango's weapon - handling abilities would make for an exciting adventure.
A fanfiction might depict Inuyasha and Sango training together. Inuyasha could teach Sango some of his demon - fighting techniques, and Sango could show Inuyasha how to better handle her weapons. This exchange of skills would not only strengthen their combat abilities but also their relationship.
One possible fanfiction could be about Inuyasha and Sango getting lost in a winter forest on Christmas Eve. They have to rely on each other's skills to find their way back. Inuyasha uses his demon senses, while Sango uses her knowledge of the land. Along the way, they start to see each other in a new light and their friendship deepens.
There could be a fanfic that delves into their backstories more. For instance, exploring Sango's past as a demon slayer in greater detail. How she overcame her family's tragedies and how that has shaped her. Inuyasha and Kagome could be part of this exploration, learning more about Sango and in turn, Sango learning more about their own complex pasts and how they are dealing with it.
A favorite moment could be when Inuyasha saves Kagome from a dangerous demon in a fanfic. His quick reflexes and determination to protect her show the depth of his feelings. Sango might be there to provide backup, and the way they all work together in that intense moment is really exciting.
One highly regarded fanfiction might be the one titled 'A Moment of Tenderness' which beautifully depicts the relationship between Inuyasha and Sango leading up to their first kiss. It has great character development and the build - up to the kiss is very well - written.
Another theme is sacrifice. Often in these fanfics, either Inuyasha or Sango has to sacrifice something for the other's sake. For example, Sango might sacrifice her safety to protect Inuyasha. This shows the depth of their connection.
Well, they could start the story by accidentally meeting while shopping for Christmas presents in a small market. Inuyasha is grumbling about all the humans and their strange customs, but Sango is enjoying the festive atmosphere. They then decide to go on a short journey together to find a special Christmas flower that is said to bring good luck. This journey makes them talk more and understand each other better.
In fanfiction, the love between Inuyasha and Sango can be really interesting. Some fanfictions might show how they gradually develop feelings for each other during their adventures. Maybe they start off as comrades, fighting side by side against demons. Then, as they face more and more challenges together, they begin to notice the special qualities in one another.
One common theme is the 'forbidden love' aspect. Since Inuyasha is a half - demon and Sango is a demon slayer, their relationship goes against the norms of their respective groups. Another theme could be 'overcoming differences'. They have different backgrounds and purposes initially, but in fanfiction, they work through these to be together.
