Sasuke would also be deeply affected. Despite their complex relationship, Sakura has always been important to him. Her death could lead to a lot of self - reflection on his part and might even make him more withdrawn as he blames himself for not being there to protect her.
The other members of the village would be in mourning too. Sakura is a respected kunoichi. Her death could lead to a sense of insecurity among the villagers as they realize that even strong shinobi like her are not invincible. It could also inspire the younger generation to train harder in her memory.
She might become more confident, or overconfident. Having the Death Note gives her a huge advantage over her enemies. She could start to rely too much on this power and think she can solve all problems with it. This could lead to her making mistakes and alienating her friends.
Her relationship with Naruto could change. Naruto might be in awe of her new powers and see her in a different light. He could rely on her more for certain missions that require her plant - related skills, like using her plants to track enemies or create barriers.
He might be really good friends with Naruto. Since Naruto is always looking for friends and acceptance, Sakura's twin could be one of the first to see Naruto's potential and befriend him. They could train together and share their dreams of becoming great ninjas.
If Sakura had a new Kekkei Genkai in Akatsuki fanfiction, it could completely change her role. For example, if her Kekkei Genkai was something that gave her an edge in combat, she might be more of a front - line fighter in the Akatsuki rather than just a healer. She could be sent on dangerous missions where her unique abilities are required to succeed.
If Sakura had a different past, say she was trained by a different master who taught her a more aggressive fighting style, her relationship with Sasuke might be different. She could be more of an equal to him in terms of combat ability right from the start, which might make Sasuke respect her more quickly. Instead of the initial one - sided crush, they could start as comrades with mutual respect.
She might become more aggressive. Saiyans are known for their fighting spirit and aggression in battle. Since Sakura is a fan, she could start to adopt some of these traits. For example, she may be more willing to take on opponents head - on rather than relying on her more strategic ninja approach all the time.
On the other hand, it could also divide the community. Some fans might not like the idea of Sakura dying at all and might be critical of the fanfic. But overall, it adds to the diversity of the fanfic landscape in the Naruto fandom. It gives different perspectives on the characters and the story, which can be really interesting for those who enjoy exploring different scenarios.
Their relationship might make Sasuke a bit jealous at first. Since Sasuke has his own complex relationship with both Naruto and Sakura. But eventually, he could come to accept it. For their other friends like Kakashi, he would probably be supportive and give them some relationship advice based on his own experiences. Shikamaru might find it a bit of a nuisance at first, thinking it could disrupt the team dynamics, but then see how happy they are and be okay with it.
If her secret power is strong healing abilities, it could change the plot by allowing her team to take more risks in battles. They know that even if they get seriously injured, Sakura can heal them. So they might engage in more dangerous missions or battles against stronger opponents.
If she has new powers, her relationship with Naruto might change. He might start to rely on her more in battles, seeing her as an even stronger ally. This could strengthen their friendship.
