A plot could involve Sakura being sent to train with Jiraiya because the village leaders see potential in her that they think Jiraiya can bring out. Jiraiya would first assess her skills and then start teaching her his own special jutsu. As she progresses, she might start to develop her own unique fighting style that combines what she learned from Jiraiya and her existing medical ninjutsu. There could also be a sub - plot about her dealing with the differences in Jiraiya's rather unorthodox teaching methods compared to what she's used to in the village.
Yes, there are some out there. You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own. Just search for the key phrase'sakura is jiraiya's apprentice' and you'll likely find a variety of stories with different takes on this interesting concept.
One possible plot is that Orochimaru needs Sakura's medical skills for one of his experiments. He kidnaps her and forces her to be his apprentice. Sakura initially resists but realizes that she can learn a great deal from him. As she becomes more involved in Orochimaru's world, she starts to form her own plans. She could be secretly working on a way to use Orochimaru's resources to develop a cure for a deadly disease in the ninja world. But she has to keep her true intentions hidden from Orochimaru, leading to a tense and complex plot full of twists and turns.
There could be a plot where Sakura, under Jiraiya's apprenticeship, tries to use her knowledge of medical ninjutsu in combination with Jiraiya's combat and strategic teachings. For example, she could develop new ways to heal in the middle of a battle or use her medical skills to counteract some of the more dangerous jutsu that Jiraiya's enemies use. Also, there could be a sub - plot about Sakura's relationships with her friends in Konoha while she is away training with Jiraiya, and how they react to her new skills and experiences.
Well, one possible plot could be that Naruto would learn a whole new set of jutsu from Jiraiya much faster. Jiraiya might focus on Naruto's chakra control and teach him some unique rasengan variations early on. Also, Naruto could start traveling with Jiraiya earlier, seeing more of the ninja world and learning about different cultures and fighting styles. This would make him a more well - rounded ninja quicker than in the original story.
One plot idea could be Naruto learning some unique and forbidden jutsus from Jiraiya. For example, a jutsu that allows him to communicate with the spirits of the past Hokages for guidance. Another could be Naruto and Jiraiya going on a special mission to a hidden and dangerous land where Naruto has to use all his skills and new knowledge from Jiraiya to survive. Maybe they discover a new chakra source there.
Growth is a common theme. Naruto grows as a ninja under Jiraiya's tutelage. Another theme is the bond between them, like a father - son relationship. For example, Naruto might look up to Jiraiya for advice and support.
One possibility could be that Sakura, under Kakashi's tutelage, further hones her medical ninjutsu skills. Kakashi, with his vast experience, might teach her some unique combat strategies that combine her medical skills with offensive moves. For example, she could learn to use her chakra scalpel in more creative and unexpected ways during battles.
Well, given the popularity of Naruto and the creativity of fanfiction writers, it's very likely that there is a fanfiction where Sakura is Jiraiya's daughter. Fanfiction allows for the exploration of different character dynamics. Writers might be interested in seeing how Sakura's character would develop if she had Jiraiya as her father. Maybe she would inherit some of his skills or personality traits, and the story could take a whole new direction from there.
One possible plot could be that Harry is raised in the ninja world. He discovers his magical abilities gradually while also learning ninja techniques. Maybe he uses his magic to enhance his ninja skills, like using spells to make his shuriken fly faster or more accurately. And he has to face the challenges of both the magical and ninja worlds, such as dark wizards and rogue ninjas.
In this fanfiction, perhaps Jiraiya didn't actually die. He was in a hidden place recovering from a serious injury. When he meets Naruto again, Naruto is shocked but overjoyed. Jiraiya then shares his newfound knowledge and powers with Naruto, and they team up to take on a powerful organization that threatens the Hidden Leaf Village. Jiraiya could teach Naruto some advanced Sage Mode techniques that he had been working on during his absence.
