Well, Harry would immediately drop whatever he was doing to be by Hermione's side. He'd feel a strong sense of responsibility as they've been through so much together. Ron would be a bit more hesitant at first, but as he realized the seriousness of the situation, he'd become a great source of support. He might bring her some of her favorite wizarding treats from the kitchen. And Ginny would be like a sister to Hermione, offering her emotional support and sharing her own experiences to make Hermione feel less alone.
Harry would be extremely worried and determined to find a cure. He'd probably search every corner of the library and consult all his wizarding contacts. Ron, on the other hand, would be initially in shock but then would try to cheer her up with his clumsy humor.
Sasuke would probably be in denial at first. He has always seen Naruto as a rival and a strong force. But once he accepted the reality, he would do whatever it takes to help, maybe even going on dangerous missions to find a cure. He would also feel a sense of guilt if he had ever underestimated Naruto because of the disease.
One possible disease could be a magical malady like a spell - induced curse that slowly drains her magic. Another might be a fictional wizarding disease that affects her ability to perform spells accurately. For example, a 'Spell - Fade' disease where her incantations start to lose their potency over time.
Ruby might be a bit shocked at first, but then she'd be really intrigued. She's always open to new ideas and would probably try to find ways to apply what she reads to her own life in Remnant. Maybe she'd start thinking about how to better protect her friends from potential disease threats.
Harry would probably be very supportive. He knows what it's like to grow up without parents, and he would see Hermione's decision as a very kind and noble one. He might offer to help in any way he can, like teaching the child some of his own skills in magic or defense against the dark arts.
Ginny would be very empathetic. She'd probably try to understand Hermione's situation from a female perspective. Ginny might try to get some female friends or relatives to help out, like bringing food or warm clothes to Hermione. Luna would be her usual unique self. She might think that Hermione is on a special spiritual journey and would offer her some very strange but oddly comforting advice.
Well, initially, her friends would be stunned. Harry would be at a loss for words. He'd be thinking about all the times they had together and how Hermione's appearance was part of who she was. Ron would probably blurt out something insensitive in his shock. But as time passed, Harry would start to see that Hermione was still the same person inside. Ron would slowly come around too, especially when he realized that Hermione's decision was more complex than he first thought. Ginny would be the one to really help Hermione feel accepted, reminding her that her true self was more important than her new look.
Harry and Ron would probably be very worried. They'd rush to her side immediately. Harry might use his skills to try and find a way to heal her quickly, while Ron would be freaking out a bit but also trying to be helpful.
Hermione's friends from the Ministry of Magic or other magical organizations would also react. Those who respect Hermione for her intelligence and contributions would be supportive. They might offer her more flexible work arrangements so she can take care of the baby. However, there might be some who are envious or judgmental. But overall, Hermione's true friends would surround her and the baby with love and protection.
Harry and Ron would likely be very shocked and concerned. They know Fenrir is a dangerous werewolf, and they might not understand how Hermione got into this situation. They would probably try to persuade Hermione to leave Fenrir at first.
Hermione's friends from Hogwarts like Harry and Ron might be a bit shocked at first. Ron, in particular, might have some mixed feelings as he has had a bit of a competitive streak with Viktor in the past. But eventually, they would come around and support her. Viktor's friends from Durmstrang would probably be more accepting as they might respect his choice more blindly. They could be excited for him and offer their own unique magical gifts or knowledge for the upcoming baby.
