There's a fanfiction called 'Unlikely Allies'. It's about fem Harry who is on the run from some dark wizards and stumbles into the Inuyasha realm where she meets Sesshomaru. At first, they are at odds with each other but as the story progresses, they start to understand and respect one another. The story is full of adventure and the way the two characters from different universes interact is quite engaging.
The popularity of fem Harry and Sesshomaru fanfiction lies in the contrast between the two characters. Harry, with her magical abilities from the wizarding world, and Sesshomaru, a powerful demon from the Inuyasha universe, create a really interesting dynamic. Their different power sets and personalities make for a lot of exciting story possibilities. For example, how would Harry's spells work against the demons Sesshomaru knows? And how would Sesshomaru react to Harry's unique brand of magic? These questions draw readers in.
A third plotline could center around the challenges they face as a couple. There could be opposition from both their respective worlds. In Harry's world, the wizarding community might not understand her relationship with a non - human from another realm. In Sesshomaru's world, demons might have their own opinions about a human - like Harry being his mate. This could lead to many conflicts and a journey of them trying to be together despite all the odds.

There's also 'Fem Inuyasha's Adventure'. This one is interesting because it focuses on fem Inuyasha's journey alone at first, and then Sesshomaru enters the story later. It shows her growth as a character and how their relationship evolves in a somewhat unexpected way.

One possible plotline could be that the female Harry Potter, through some magical accident or spell, ends up in the world of Inuyasha where she meets Sesshomaru. Their initial interactions might be full of mistrust, but as they face common enemies or challenges, they start to develop feelings for each other.
Some fanfictions have Fem Sesshomaru and Inuyasha swapping powers. This creates a really interesting plot as they have to adapt to their new abilities while still being themselves. For example, Inuyasha with Sesshomaru's more refined and powerful abilities has to learn how to control them without losing his own brash nature. And Fem Sesshomaru with Inuyasha's powers has to deal with the more unruly aspects of his power.
The potential for unique storylines. Fanfiction writers can explore different aspects of their relationship, like how they might overcome their differences or what could happen if they were forced to rely on each other. It allows for a great deal of creativity. For example, a story could be set in a world where they are the last of their kind and must work together to repopulate. This kind of out - of - the - box thinking is what makes this type of fanfiction so appealing.
