Well, Naruto and Sasuke are likely to be in her natural habitat in fanfiction. Naruto is her friend and teammate, and Sasuke is someone she has a complex relationship with. Her teacher Kakashi might also be there, guiding her in training or giving her advice.
Tsunade, as the Hokage and also a powerful medical ninja, is a character that would fit into Sakura's natural habitat in fanfiction. Tsunade could be mentoring Sakura in the hospital or in matters related to being a strong female ninja. And of course, Sakura's parents might be present in some stories, adding a family - centered aspect to the fanfiction.
In Haruno Sakura fanfiction, common settings in her natural habitat might include the Hidden Leaf Village. It's where she grew up, trained, and has many of her relationships. There could also be the hospital, as she is a medical ninja, so scenes might be set there with her treating patients or studying medical jutsu.
Ino is often a supporting character. Ino and Sakura have a long - standing friendship - rivalry thing going on, and in training fanfictions, Ino can be there to either compete with Sakura or support her in her growth. Naruto and Sasuke are also typical. Naruto's positive attitude and Sasuke's skill can inspire Sakura in her training. Kakashi, as their teacher, is another one. He might guide Sakura in her training, give her advice, and help her develop new techniques.
There could be the patients, of course. Each patient might have their own unique backstory and personality. Maybe there's a young patient who is dealing with trauma, and Sakura has to find a way to reach out to them.
I don't know for sure, but since it's a fanfiction centered around Sakura Haruno, she is the main focus. However, it may also feature characters who had a major impact on her life. This could include her sensei, like Tsunade, who trained her in medical ninjutsu. There's also a possibility that new characters created specifically for this fanfiction could be main characters as well, but that's just speculation.
In some Sakura Haruno alpha fanfiction, Kakashi could be a significant character. He might act as a mentor to Sakura in her new alpha role. He could guide her in making difficult decisions, like when she has to choose between the safety of the village and the life of a comrade.
Sakura is, of course, the central character. The bullies are usually other students or characters who might be jealous of Sakura for some reason, like her popularity or special abilities. There are often also some friends or allies of Sakura, such as Naruto or Sasuke in a Naruto - themed fanfiction who might stand up for her.
Amu Hinamori would be a great character to pair Sakura with. Amu has her own set of Shugo Chara and a strong personality. Together, they could share their experiences with their Shugo Chara and learn from each other. Their different yet complementary personalities could lead to some really interesting interactions and adventures.
Naruto can also be paired with Sakura in these fanfictions. Since they are such close friends in the original, in a reincarnation scenario, their friendship could potentially turn into something more romantic. They could support each other in different ways than in their past lives.
In a crossover with One Piece, Luffy would be an interesting match for Sakura. Luffy's carefree but determined nature along with his stretchy powers could work well with Sakura's more serious and medical - based abilities. They could embark on a journey together in the crossover, facing various challenges and making new friends along the way.
The two main characters are Sakura Haruno and Doctor Lemon. Sakura Haruno could be a well - established medical professional in the story, or maybe she's still learning and growing. Doctor Lemon is an important figure as well. They could be colleagues, rivals, or even partners in some kind of medical adventure or research. Their relationship and how they influence each other will likely be central to the fanfiction.
