Naruto could develop a more refined and sophisticated side. The suit symbolizes a new level of maturity. He might become more aware of the political and diplomatic aspects of being a ninja leader. For example, he starts to use more words and less brute force in negotiations.
For Naruto, he would become more aware of different realms and powers beyond his shinobi world. His experience with Hades could make him more mature in handling situations that seem impossible at first. He might also develop a new sense of respect for the afterlife and its rules. As for Hades, he could start to see the value in the living world more, especially through Naruto's eyes. Maybe he becomes less cold and more empathetic towards the living, which is a big change for a god of the underworld.
In this fanfiction, Naruto's development as a demon would mean he has to face the prejudices of the village all over again. This would make him more determined to prove himself. Hinata would develop her own skills in order to protect Naruto. She might also develop a new sense of leadership as she stands up for Naruto against the village's doubts. Naruto would learn the value of having someone like Hinata in his life and would strive to be a better version of himself, both as a demon and as a person who is part of the village.
For Naruto, it could further enhance his reputation as a hero. He might gain more respect from the Hidden Sand Village where Pakura is from. His self - confidence in his ability to save anyone in need would also grow. For Pakura, if she was in a state of despair before being saved, she could regain her hope and determination. She might start to believe in the power of friendship across villages like Naruto does.
For Naruto, he would likely become more mature and responsible. His carefree nature would be tempered by the need to protect Konan and their unborn child. He might also start to think more about the future and how to create a stable world for his family. Konan, she would become more vulnerable yet also stronger in a way. Her focus would shift from the Akatsuki's goals to the well - being of her baby, and she'd have to learn to trust Naruto completely.
Naruto might become more in tune with his emotions. Living with Ino, who is perceptive about feelings, could make him more self - aware. For example, he might start to understand his own feelings towards his friends better.
The relationship between Naruto and Kaguya would also develop in unique ways. At first, Kaguya might be distrustful of Naruto, but as he continues to save her and show her kindness, she could start to respect and even care for him. This relationship dynamic could add depth to both characters and the overall fanfiction story.
For Naruto, he could develop more understanding of the darker side of the ninja world through his interactions with Tayuya. Tayuya, on the other hand, might start to see the value of friendship and loyalty like Naruto has. For example, Naruto's unwavering belief in his friends could rub off on Tayuya, making her question her previous solitary and somewhat ruthless ways.
Anko might develop a softer side through her interactions with Naruto. She has a tough exterior due to her past, but Naruto's unwavering optimism and kindness could start to break down her walls. She could become more open and trusting towards others in general.
Another possible development is that she gains the ability to transform into different forms not just for combat but also for communication. For example, she could take on a more human - like form to better interact with the villagers, which helps to bridge the gap between her and the humans and also shows her adaptability and evolution as a character.
Potential character development for Naruto could be that he becomes more adaptable. Serving Orochimaru would put him in situations he's not used to, forcing him to think on his feet. He may also develop a darker side, as Orochimaru's influence seeps in, but at the same time, he could become more determined to uphold his own values. As for Orochimaru, he might start to respect Naruto's tenacity and might even consider changing his ways a bit, or at least re - evaluating his plans in light of Naruto's presence.
