Issei could develop into a more self - less character. His love for Fem Trihexa might drive him to put her needs and the needs of their relationship above his own desires. He may also become more of a leader in the supernatural world, as his marriage to Fem Trihexa gives him a certain status. Fem Trihexa would develop in the sense that she becomes more involved in the day - day affairs of the world. Instead of just being a powerful, distant entity, she would be part of a community through her marriage to Issei, and this would change her perspective and actions.
For Issei, his development could be about learning to balance his new role as a husband with his existing responsibilities. He might grow in terms of his strategic thinking, as he has to protect his wife and their relationship from those who oppose it. Fem Trihexa may start to develop a sense of vulnerability. In a marriage, she has to open up to Issei, which is new for her as a powerful being. This could lead to her showing a more human - like side, with emotions like love, fear, and hope.
Well, one possible plot could be that they have to face challenges from different factions in the supernatural world. Since Issei is a well - known character in the DxD universe and Fem Trihexa is an extremely powerful entity. Their marriage might be seen as a threat or a new hope depending on who's looking at it. Maybe they work together to bring about peace among different species while also dealing with their own relationship issues, like misunderstandings and differences in their ways of thinking.
For Fem Jaden, you can focus on her femininity and how it interacts with her personality. For example, if she's strong - willed, show how she uses her grace and charm to get what she wants. For Zane, you could develop his character by highlighting his loyalty. Maybe he has a code of honor that he follows strictly. This could be a source of conflict and also a way to bring him closer to Fem Jaden.
Naruto would likely develop more control over his chakra with the help of the fem Kyuubi. He might become more mature in his approach to battles and life in general. The fem Kyuubi, on the other hand, could develop more human - like emotions as she spends time with Naruto.
At first, it might be a bit rocky. They are both strong - willed individuals. Naruto is used to being the center of attention and having his own way, and fem Sasuke has her own ideas. But as they live together, they start to understand each other more. For example, Naruto realizes that fem Sasuke's aloofness is sometimes just her way of protecting herself. And fem Sasuke sees that Naruto's boisterousness is his way of showing his love for people. So they gradually become more in tune with each other's needs and wants.
The fanfic could develop their relationship by having them face challenges together. Like when there is a new villain in town that targets Deku's family. Ochako and Deku would have to rely on each other, trust each other more, and this would deepen their relationship.
The relationships could develop gradually. At first, Naruto might be a bit wary of the Fem Kyuubi and Fem Bijuu because they are so different from what he's used to. But as they fight together against common enemies, a sense of trust could start to form. For example, if they save each other's lives in battle, that would strengthen their bond.
As time passes, they would likely face external threats to their relationship. Maybe some ninja from other villages don't approve of their union. However, this would only make them stronger as they stand up for each other. They would communicate more and learn to compromise, like when deciding which village's traditions to follow in their daily life.
Perhaps their relationship begins as a friendship based on mutual respect. Naruto respects fem Haku's strength and her loyalty. Haku admires Naruto's determination and his ability to see the good in people. As they work together on various missions, they start to notice little things about each other that they find endearing. Small gestures like Naruto sharing his ramen with Haku or Haku mending Naruto's clothes become important in their relationship development. These small but meaningful interactions build up their feelings until they decide to get married.
When developing the characters in this fanfic, consider their physical appearances as well. The OC's appearance can say a lot about them. For example, if they have a unique hair color or style, it could be related to their heritage or a sign of their rebellious nature. For Fem Vali, her appearance might change slightly as she becomes closer to the OC. Maybe she starts to wear a certain accessory that the OC gave her. In terms of their personalities, you can make the OC a bit of an outcast at first, which makes Fem Vali's interest in them more interesting. And for Fem Vali, you can show her as initially cold but warming up to the OC over time through small, meaningful interactions.
The relationship between Naruto and the fem werewolf could start as a friendship based on mutual respect for each other's abilities. Naruto would be intrigued by her werewolf powers. With the fem Kyuubi, Naruto already has a complex relationship due to the Kyuubi inside him. As the story progresses, the fem werewolf might develop romantic feelings for Naruto, which could make the fem Kyuubi a bit envious at first. But eventually, they could all form a strong, platonic bond where they support each other in different ways, like in battles or in dealing with the politics of the Hidden Leaf.
