One plot idea could be a story where Fem Naruto and Inuyasha team up to fight a common enemy. Maybe a powerful demon that has the ability to disrupt the balance between the ninja world and Inuyasha's feudal Japan. They could combine their unique powers, like Naruto's ninja skills and Inuyasha's swordsmanship and demon powers.
Inuyasha's personality can be developed by showing his growth in accepting Fem Naruto. At first, he might be dismissive of her because she's not from his world and seems weak compared to him. But as he sees her tenacity and the power of her ninja techniques, he could start to see her as an equal. His own issues with trust, especially after his past with Kikyo, can be further explored in relation to how he trusts Fem Naruto and whether he's willing to let her into his heart and share his secrets.
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.
A possible plot could be that the female Inuyasha gets transported to the Naruto universe. She then teams up with Naruto to fight a common enemy that is threatening both their worlds. Along the way, they learn about each other's powers and cultures, and a friendship (or more) develops between them.
One popular Inuyasha and Fem Sesshomaru fanfiction is 'The New Path'. It explores a world where Sesshomaru is reimagined as a female character and her interactions with Inuyasha take on a whole new dynamic. It has an interesting plot that involves them teaming up against a new common enemy while also dealing with their own complex relationship.
Another great one is 'Fate's Intertwining'. This fanfiction focuses on how their destinies are linked in ways they don't initially understand. It has a lot of emotional depth and some beautifully written scenes between Sesshomaru and Fem Inuyasha.
Well, it depends on your definition of 'good'. There are some 'naruto x fem inuyasha fanfic' out there. However, the quality can vary a great deal. Some might focus more on the action elements, borrowing from both Naruto's ninja battles and Inuyasha's fights against demons. Others could be more about the relationship development between the characters, which might be a bit more of a slow - burn story.
One way is through crossovers. For example, a character from Naruto could accidentally end up in the world of Inuyasha. They might use their unique ninja skills, like Naruto's shadow clones, to help fight Inuyasha's enemies. This would add an interesting dynamic as the ninja abilities are different from the demon - slaying techniques in Inuyasha's world.
It's really hard to say. Naruto has his incredible chakra powers, his ability to go into different forms like Sage Mode and Nine - Tails Mode. He's also a very skilled ninja with a lot of combat experience. But Inuyasha has his demon strength, his Tessaiga which can cut through almost anything, and his ability to sense demons. In a straight - up fight, it would probably depend on the situation, like the terrain and whether they have any prep time.
The theme of redemption can also be explored. Suppose a villain from Naruto's world ends up in Inuyasha's world. The different environment and the values of the people there might make them question their actions and seek redemption. It's an interesting way to give depth to otherwise one - dimensional characters.
