In this fanfiction, Naruto is the central character as it focuses on his actions regarding the Hiraishin. Besides Naruto, other main characters could include the old ninja masters who might have some insights into the Hiraishin. They could be characters from Naruto's village or even from other hidden villages. And of course, Naruto's friends like Sakura might play a role. Maybe she helps Naruto in some way, perhaps by providing medical support during his intense training to recreate the Hiraishin.
The main character is Naruto as it's his story of recreating the Hiraishin. However, other important characters could be those related to the origin of the technique. Minato, Naruto's father, could be a significant character even if only in flashbacks or through some spiritual connection. Also, Jiraiya might be involved as he was Minato's teacher. His knowledge and teachings could be passed on to Naruto to help him in recreating the Hiraishin. Additionally, the Akatsuki members might make an appearance as antagonists, trying to stop Naruto from achieving his goal of recreating the Hiraishin.
I'm not entirely sure about the specific key plot points as I haven't read this particular fanfiction in detail. But generally, it might involve Naruto's exploration and improvement of the Hiraishin technique. Maybe he discovers new ways to use it in battles or for other purposes like quick transportation around the ninja world.
Obviously, Naruto is one of the main characters since it's about him knowing the Hiraishin. Kakashi could also be an important character as he has some knowledge of the technique as well. And his friends like Sasuke and Sakura might also be involved, as they often play important roles in Naruto's adventures and could be affected by his use of the Hiraishin.
In this fanfiction, Naruto is the central figure. However, other important characters could include Kakashi. Since Kakashi has knowledge about many techniques, he could be a mentor to Naruto in his Hiraishin training. Also, characters like Jiraiya might make an appearance. Jiraiya could offer his wisdom and experience, having seen many powerful jutsus in his lifetime and helping Naruto in understanding the deeper aspects of the Hiraishin.
There could be a rival character, a fellow ninja who is jealous of the seal master's skills with the Hiraishin. This rival might constantly try to undermine the seal master or steal their techniques, adding a layer of conflict to the story.
Naruto himself is often a main character in these fanfictions as he has a connection to the Hiraishin no Jutsu through Minato. Also, Minato is frequently featured as he was the original user of the jutsu. Sasuke can also be involved as he and Naruto have a complex relationship and their interactions can be explored in relation to the jutsu.
Minato Namikaze is often a central character as he was the one who originally used the Hiraishin technique in the Naruto series. Naruto himself also features prominently in many fanfictions as he is Minato's son and may inherit or learn more about the Hiraishin. Another character could be Kakashi, who had an indirect connection to the Hiraishin through his relationship with Minato.
Naruto is also quite popular in these fanfictions. Fans love to write about him learning the Hiraishin no Jutsu and how it changes his fighting style. He's such a beloved character in the Naruto universe that seeing him master this powerful jutsu is always an exciting concept for readers.
Kankuro would also make sense. As a skilled puppeteer from the Sand Village, he could teach Naruto the basics of puppetry. Kankuro might be initially hesitant, but Naruto's determination could win him over. He could teach Naruto how to control puppets with precision and how to customize them for different battles.
One challenge could be the complexity of the technique itself. Hiraishin is a very advanced ninjutsu, and Naruto might struggle to understand the chakra control required for it.
The idea of fem Naruto using Hiraishin in fanfiction is really cool. It can change the power dynamics in the story. Fem Naruto may have a different approach to using the technique compared to the male Naruto. Maybe she focuses more on precision and strategy rather than brute force.
