A shy boy who also loves to read and he and Sakura bond over their shared love for books. They might form a study group together and support each other in their academic pursuits.
It could be her friends from the present who somehow also get sent to the past with her. Maybe Tomoyo, who could be helpful in creating new outfits for Sakura to blend in with the past's fashion.
It could be about Sakura making new friends at the boarding school. She might face challenges like homesickness or difficult classes, but over time she adapts and thrives.
One of the main characters could be Sakura's mother. Mothers are often intuitive about their children's problems. She could be the one who eventually helps Sakura open up about her self - harm. Then, there might be a new acquaintance in Sakura's life, someone she meets randomly. This person could have had a similar experience in the past and be able to offer unique advice and support to Sakura.
Tomoyo would also be an important character. She would be very worried about Sakura. She might use her skills in making costumes to create some special baby clothes for Sakura. And she would be constantly by Sakura's side, taking care of her and trying to comfort her.
The Akatsuki members would be the main ones. It could include Itachi, who is known for his complex character and powerful abilities. His relationship with Sakura could be an interesting aspect, whether it's one of mutual respect or a more adversarial one.
Sakura's family members could play important roles. Her parents could initially be hesitant about her decision to adopt but later come around and become loving grandparents to the adopted child. Also, there could be other ninja in the village. For example, Hinata could be a character. She might become friends with the adopted child and help Sakura with things like cooking for the child or teaching the child some basic self - defense moves.
Sakura's friends like Naruto and Sasuke could be main characters. They might be the ones trying to find a way to save her. They could be using their skills and powers to look for a cure or a solution.
Naruto is often a popular character in these fanfictions. He could be Sasuke's rival for Sakura's attention or a good friend who tries to help them get together. Ino is also a common character. She might be Sakura's friend or sometimes a rival in matters related to Sasuke. Kakashi could be their teacher who gives them advice about their relationships and schoolwork.
Sakura could have interactions with the Weasley family. Ginny Weasley might become her friend and they could have girl - talk about magic and boys. Fred and George could also be part of her story. They might play some pranks on her at first but then become good friends. And don't forget Neville Longbottom. Sakura could help Neville gain more confidence in his magic abilities as they study together in the Hogwarts library.
Definitely some of the Akatsuki members. Itachi could be one. He is a complex character with his own motives. His presence could add a lot of mystery to the story as Sakura might try to figure out his true intentions. Another could be Deidara. His explosive personality and love for destruction could create some intense confrontations with Sakura.
