Harry often tries to be there for her. He might not fully understand her depression at first, but he'll stay by her side, offer a listening ear and try to cheer her up in his own clumsy way, like suggesting they go on an adventure or something.
Ino, being her former rival and now friend, could be very empathetic. She might try to get Sakura out of her shell by taking her shopping or just having girl - to - girl talks. Kakashi, as their teacher, would probably be observant. He could give her special training or tasks to boost her confidence. And the other members of their ninja team would likely offer their support in different ways, like sharing their own experiences or just being there for her.
Harry would probably be very concerned and protective. He's been through a lot himself, and he'd want to be there for Hermione. He might try to comfort her by just sitting with her quietly, sharing his own experiences of tough times to let her know she's not alone.
Harry would probably be extremely worried. He'd immediately rush to her side, trying to figure out how to help. Ron, on the other hand, might be in a bit of a panic at first but then would do whatever he could to protect her while waiting for help. Hagrid might bring some of his home - made remedies, thinking they could work on her injury.
Well, it really depends on the characters. Some might be shocked at how they're portrayed in the fanfiction. For example, a heroic character might be dismayed if they're shown as a villain in the story. Others could be amused, especially if the fanfiction has some really out - there or comical interpretations of them.
Well, Harry might be a bit surprised at first. But he could also be supportive as he values both Sirius and Hermione. He might see that Sirius makes Hermione happy and be okay with it.
Their friends would likely be very concerned. Shikamaru, being Temari's close friend and Naruto's teammate, would try to use his intelligence to figure out what's wrong. He might start by just spending time with them, not pushing them to talk right away. Sakura, as Naruto's long - time friend, would probably be more direct. She'd try to get Naruto to open up about his feelings, using her medical knowledge to also check if there's any physical ailment contributing to his depression. For Temari, Ino could reach out, as she's good at getting into people's heads. She'd offer Temari support and try to make her feel better about herself.
She might initially be in shock. Hermione is used to relying on her friends, so the betrayal would be a huge blow. She could then become angry and start to isolate herself. In some fanfictions, she might try to figure out why they did it on her own, using her intelligence to uncover the truth.
Harry would be extremely worried. He'd probably rush to her side immediately and try to do whatever he can to help. He might blame himself for not being there to protect her. Ron, on the other hand, would be in a state of shock at first and then would try to use his humor to lighten the situation a bit while still being very concerned. Hagrid would be devastated. He sees Hermione as one of his students he cares about, and he'd likely bring some sort of magical creature - related remedy, thinking it could help.
Well, the other students in Gryffindor would likely be a bit taken aback at first. But then, knowing Hermione's intelligence and her tendency to be different, they would probably accept it. They might be curious about how she's going to manage to keep up the charade. The Hufflepuffs would be generally kind and understanding, perhaps even offering to help her if she needs it. The Ravenclaws would be intrigued by the idea and might study her transformation from a more academic perspective. The Slytherins, as a whole, would be more likely to try and use her disguise against her, either by blackmailing her or trying to expose her in a way that would cause her and her friends embarrassment.
Hermione would probably be the first to notice the signs of abuse. She'd be very methodical about it, perhaps making a list of all the things that seem off. Ron, on the other hand, would be more impulsive. He might get angry right away when he realizes what has been happening to Harry. Dumbledore, being the wise figure, would likely start to put plans in motion to protect Harry and also to deal with the source of the abuse.
