Another way is through character backstories. If the fanfiction delves into their pasts, perhaps they find out that they have some sort of connection from long ago. This connection can be explored and can bring them closer together. For instance, they might discover that their families were once allies, and this realization makes them see each other in a new light.
Their relationship can be developed through shared adventures. For example, when they face a powerful new demon together. Inuyasha can protect Kagome in a really heroic way, and Kagome can use her spiritual powers to help Inuyasha in a crucial moment. This would strengthen their bond.
Their relationship could start with mutual mistrust. Inuyasha might be skeptical of Female Shippo's motives or abilities at first. But as they face common enemies together, they begin to respect each other. For example, if they team up to fight a demon that is causing chaos in a village, they see how each other fights and starts to rely on one another.
Well, they could be transported to the Inuyasha world and their relationship could be tested in new ways. For example, they might face more dangerous situations together than they did in the Naruto world. This could make them rely on each other more and deepen their bond. Hinata could also show her loyalty to Naruto in front of Inuyasha and his group, which would make Naruto appreciate her even more.
You can start by giving them a common goal. For instance, if there's a threat to the world of feudal Japan that only they can stop together. This would force them to interact and gradually build some sort of understanding.
Communication is key. In the fanfiction, they could have deep conversations about their dreams, fears, and past traumas. Laslow might share his experiences as a wandering mercenary, and Corrin could talk about her complex family situation. Through these exchanges, they would understand each other better and draw closer. Another aspect could be through acts of self - sacrifice. If one of them is in danger and the other risks their life to save them, it would strengthen their bond significantly.
Another way is through sacrifice. If Orihime sacrifices something important for the sake of an Espada, or vice versa, it can deepen their relationship. This act of selflessness can show the depth of their feelings for each other and be a turning point in their relationship within the fanfiction.
The relationship can be developed through shared experiences. For example, they could go on a joint mission to retrieve an important artifact. During this mission, they face various challenges together, which helps them bond. They might have to trust each other with their lives, and this deepens their connection.
By showing them having heart - to - heart conversations. For example, they could talk about their experiences growing up as demigods, their fears, and their hopes. This would deepen their connection.
By creating more shared experiences. For example, they could go on a journey together to find a special item or to help someone. During this journey, they would face challenges and have to rely on each other, which would strengthen their bond.
The relationship can be developed through shared missions. When they are on a mission together, they can rely on each other's skills and learn from one another. For example, Naruto's vast combat experience can help Sarada in tough battles, and Sarada's fresh perspective can give Naruto new ideas.
