To write their character development, think about their goals in high school. Female Naruto might want to be popular and make a lot of friends, while Sasuke just wants to be left alone to study. But as they get closer, their goals start to change. Naruto realizes that having a deep connection with one person like Sasuke is more important than having a lot of shallow friendships. Sasuke starts to care more about Naruto's well - being than his own isolation. You can show this through actions like Naruto giving up a party to study with Sasuke when he's having trouble in a subject, and Sasuke standing up for Naruto when some students make fun of her.
Gaara should be initially cold and distant. His development could be triggered by Naruto's persistent attempts to befriend him. Maybe Naruto invites him to a school event and Gaara reluctantly goes. There, he experiences a sense of belonging he has never had before. This makes him open up more, start smiling, and gradually become more involved in school life and closer to Naruto.
In a highschool fanfiction, Neji could be written as a character who is slowly breaking free from the constraints of his family's traditional views. Sakura can be the catalyst for this change. She encourages him to pursue his own dreams and interests. As for Sakura, her character can develop from being a bit naive to more worldly. Neji's wisdom and life experiences, even in highschool, can contribute to this. Their relationship is like a two - way street where they both grow and change as individuals through their interactions with each other.
For Naruto in Anbu, you could start with his initial brashness still showing but slowly being tempered by the strict Anbu code. As he interacts with Yugao, he starts to see things from a different perspective. Yugao, on the other hand, could start as a reserved and focused ninja. When she meets Naruto, his energy starts to break down her walls. You can show their development through their conversations and how they react to different situations together.
When writing their character development, consider the challenges they face. Naruto in the Anbu has a dark side to his work that Ino may not understand at first. Have Ino be curious and try to understand Naruto's world, which in turn makes Naruto more willing to open up. For Ino, have her face some self - doubt in her ninja abilities, and Naruto's belief in her can boost her confidence. Their relationship should be a two - way street where they both evolve based on their interactions and the situations they encounter together.
For Issei, you can start by showing his initial reaction to Bennia. Maybe he's a bit intimidated at first by her unique qualities. Then, as they interact more, he starts to see her in a new light and his character develops as he learns to respect and appreciate her differences. For Bennia, her development could be about opening up more. She might be initially reserved, but through her experiences with Issei, she becomes more confident and outgoing.
Their relationship could start off rocky, with Naruto being his boisterous self and fem Sasuke being aloof. But as they interact more in classes, study groups, or school events, they might start to understand each other better. Naruto's positive attitude could gradually break down fem Sasuke's walls.
Writers often show female Naruto becoming more nurturing. She's always been strong -willed, but now she has a new side as she's going to be a mother. Sasuke, on the other hand, may start to open up more emotionally. He might share his fears and hopes for the future with female Naruto more than he ever did before.
To write their character development well, give them common goals. Let's say they both want to improve the relations between different factions in the DxD world. As they strive for this goal, they learn from each other's strengths and weaknesses. Issei can learn Kuroka's stealth and cunning, while Kuroka can learn Issei's determination and ability to inspire others. This mutual learning process will enhance their character development.
Another idea is that there's a high school sports competition. Female Naruto is on the track team and Sasuke is on the soccer team. Naruto has always admired Sasuke from afar. During the competition, an accident occurs where Naruto gets hurt while trying to help Sasuke's team. Sasuke then feels responsible and starts to take care of her, leading to a closer bond between them.
For Hiccup, start with his existing traits like his courage and intelligence. As he gets closer to the female Toothless, he could become more empathetic towards her species. Maybe he starts to understand the female Toothless' perspective better, which changes his approach to dealing with dragons in general. For the female Toothless, show her initial wariness of Hiccup, and then as time passes, her trust in him grows. You can do this through their interactions, like how she lets Hiccup touch her in certain ways that she wouldn't allow others to do.
