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.
It could be that the child has an older sibling who was separated from them before Sakura adopted the child. This older sibling could be a main character as they search for their younger sibling. When they find out that Sakura has adopted the child, they have to decide whether to trust Sakura and be part of the new family she is creating. This could lead to a lot of drama and emotional moments in the fanfiction.
The plot might be that Sakura has always wanted a family but couldn't have one in the normal way. One day, she comes across a child who has been abandoned. She instantly feels a connection and decides to adopt. Along the way, they bond over shared interests. For example, if Sakura likes gardening, she teaches the child about plants and they grow a beautiful garden together, strengthening their relationship.
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.
Well, it could be Slenderman as the creepypasta. He's a very well - known figure in the creepypasta world. The child could be an orphan who has had a series of strange and unexplained events happen around them, which is what draws Slenderman to adopt them.
It could be an orphaned wizard child from a family that was killed by Death Eaters. This would give Snape an added sense of responsibility as he might feel guilty for being associated with the Death Eaters in the past.
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.
Obviously, Sakura herself would be a main character. Her friends like Naruto and Sasuke could also be main characters. Naruto might be the one who is overly excited and wants to play with child - Sakura all the time, while Sasuke would be more focused on finding a way to turn her back. Kakashi could also be involved as the mentor figure who guides them through the process.
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.
Perhaps an old enemy of Naruto or Sakura who was thought to be defeated but actually survived. They see the child as an easy target to get back at their parents. For example, if there was a rogue ninja from their past who held a grudge, they could come back and try to use the child to draw Naruto and Sakura into a trap. This antagonist would be very cunning and know all the weaknesses of Naruto and Sakura, which they could try to exploit through the child.
