Her relationship with Edward would be different. Without the family connection through Charlie, she might be more hesitant to trust Edward at first. Their meeting might seem more like a chance encounter between two strangers, and she wouldn't have the safety net of Charlie's presence in Forks.
With Jacob, their relationship would also shift. Since she's not Charlie's daughter, she might not be as involved in the Quileute tribe's affairs through family ties. Jacob might view her more as an outsider initially, and their friendship might develop more slowly as she has to prove herself worthy of his trust and the tribe's acceptance.
In relation to the other students at school, Bella would be more of a true outsider. Without the connection to Charlie, she wouldn't have that local - girl - from - a - respected - family status. She might be more of a loner at first, and it would take more effort for her to make friends. Her relationships would be more self - made rather than based on family reputation.
Her relationship with Naruto would be different. Instead of the typical male - male rivalry, there could be a more complex dynamic. Naruto might be more protective of her at times, or there could be a romantic undertone to their friendship. With Sakura, they could become closer as two strong female characters. Sakura might see Sasuke as an inspiration for her own growth. And with Kakashi, he would have to adjust his mentoring style as Sasuke is now a girl, perhaps being more cautious and aware of the different challenges she might face.
If Bella was Carlisle's daughter, her relationship with the other Cullen siblings would be altered. She would be part of the family in a more fundamental way. For example, Alice might see her more as a sister to protect and guide, rather than just a friend. And Rosalie might have a different attitude towards her, perhaps being more accepting since she is Carlisle's daughter. Jasper could also be more involved in her training or development as a vampire, as he has his own skills and experiences to share.
In a family setting, her relationship with her parents might also shift. Her father might become more protective, while her mother might start to have more mother - daughter type of conversations with her. And with siblings, there could be new dynamics depending on whether they are older or younger. If she has an older brother, he might be more protective too, and if she has a younger sister, they could become closer as sisters often do.
With Naruto, their friendship would likely become more complex. Naruto might initially be shocked but then become very protective. Their rivalry could also take on a different tone, perhaps less about pure power and more about Sasuke's secret and how Naruto can help keep it. As for Sakura, she might be jealous at first if she discovers Sasuke's true gender and realizes that Sasuke has been hiding this from her. But she could also become a closer friend as they share more feminine experiences.
Her relationship with Thor would be complex. He would be her father, but they might have initial misunderstandings due to their different upbringings. Thor might be overprotective at first, which could cause some friction between them. However, as they get to know each other better, they would develop a strong bond.
Her relationship with Dumbledore would be extremely complex. Dumbledore, knowing her parentage, would be both watchful and perhaps a bit more guarded around her. He would try to guide her away from the dark path but also might not fully trust her at first. With Ron and Hermione, they might initially be shocked and a bit hesitant. However, their loyalty to her as a friend could eventually overcome their doubts, but there would always be a bit of unease, especially when it comes to using dark magic.
Her relationship with the camp counselors would be really complex. They have to protect the camp and its inhabitants, so they'd be hesitant to fully trust her. However, as she participates in camp activities and battles, she could earn their respect. In terms of romantic relationships, a son of Athena might be initially attracted to her intelligence but then struggle with her heritage. And she might have a mentor - like relationship with an older demigod who has also had a difficult family history.
When Shirou turns into a girl, her relationships with other characters are bound to be different. Her male friends might start to see her in a more delicate way, even if she still has her old - Shirou - like strength. There could be a change in the power dynamics within the group she belongs to. Her relationships with female characters could range from being mentored by them in how to be a girl to facing competition from them. And any romantic relationships she had or hoped for would need to be re - examined, as the gender roles and expectations are now different.
Her relationship with Naruto might change as she could now use the Byakugan to keep an eye on him better in dangerous situations. With Sasuke, she might be more confident in facing him if he ever turned against the village again. And with Hinata, they could become closer as Sakura would understand the power of the Byakugan and they could share experiences related to it.
With Weiss, their relationship could be more strained at first. Since Weiss has some preconceived notions about Faunus, she might be initially distrustful of Ruby. But as time goes on, they could overcome this. With Blake, they might bond more deeply as they both share the Faunus experience in a way. And with Yang, Yang would be very protective of Ruby, especially if Ruby faced any discrimination because of being a Faunus.
