In some Sango Lemon fanfiction, they might be on a quest to save their village from a great danger. Along the way, they discover new things about themselves and each other. Sango's strength and Lemon's intelligence could combine in unique ways to overcome the obstacles in their path. Their relationship could also develop romantically as they rely on each other more and more.
One interesting story could be about Miroku and Sango going on a journey together and facing various challenges that strengthen their bond. Maybe they encounter a powerful demon that they have to defeat using their combined skills.
One interesting theme could be their adventures together. For instance, they might go on a quest to find a rare weapon that can defeat a new and powerful enemy. This would involve them traveling to different places, facing various challenges, and relying on each other's skills.
Since 'lemon' fanfiction usually contains inappropriate content, I can't really recommend any. But in general, for Kagome and Sango, a fanfiction could be written about how they bond over their shared experiences in the Inuyasha world. They both have unique relationships with Inuyasha, and a fanfic could explore how they handle the challenges that come with those relationships while also strengthening their own friendship.
One interesting plotline could be them going on a secret mission together without the knowledge of the male characters. They'd have to rely on each other's skills, with Sango's combat expertise and Kagome's archery and spiritual powers. It would be a story of female empowerment and friendship.
One idea could be that Sesshomaru and Sango are forced to team up to fight a common enemy stronger than they've ever faced before. During their journey together, they gradually learn to respect each other's skills. For example, Sango's expertise with her weapon, the Hiraikotsu, impresses Sesshomaru. Another plot could involve Sesshomaru getting injured and Sango taking care of him in a hidden forest. This situation would make Sesshomaru see Sango in a different light and start to develop a friendship that could potentially turn into more. A third idea is that they both get transported to a strange, magical realm and have to rely on each other to find their way back home while also uncovering the secrets of the new world.
In non - lemon fanfics, one interesting aspect is their mutual respect. Sango respects Inuyasha's power and his determination to defeat Naraku. Inuyasha, in turn, respects Sango's skills as a demon slayer. For example, in 'The Quest for Redemption' fanfic, they often rely on each other's strengths during battles.
One plot idea could be that Sango and Miroku go on a quest together to find a rare and powerful weapon to help in their fight against demons. Along the way, they face various challenges that test their skills and their relationship. Another idea is that Miroku gets injured and Sango has to take care of him, and during this time, they have deep conversations that bring them closer.
One popular trope is the 'found family' where Kagome, Sango and Lemon form a very close bond that's like a family. Another is the 'power - up' trope where they gain new powers or abilities together. For example, they might discover a new spell that combines their individual strengths.
