Jiraiya could also be involved. Jiraiya, being Naruto's mentor, has a vast knowledge of different jutsus. He might have come across some ancient scrolls or techniques that are related to the creation of Kirin. He could guide Naruto in understanding the more spiritual and chakra - flow aspects of creating such a powerful jutsu.
Well, in such a fanfiction, Naruto might discover a new chakra ability that allows him to create Kirin. He could be in a tough battle where his usual jutsus aren't enough. So, he taps into some hidden potential within himself to form Kirin. Maybe he combines his own wind - style chakra with some newfound lightning - style chakra he got from a special training or encounter.
One possibility is that he could rewrite his own adventures in a more humorous or self - deprecating way. For example, making fun of his early failures in ninja training.
His friends like Sasuke would most likely support him. Sasuke, having walked a long path of redemption, would see Naruto's vision of an empire as a way to finally achieve the peace they both have been longing for.
The purpose could be to protect the weak. Naruto has always been about protecting those who can't protect themselves. So his organization might focus on safeguarding small villages or groups that are vulnerable to attacks from rogue ninjas or larger, more aggressive villages.
If Naruto creates a lightsaber, it could be related to his connection with Kurama. Kurama's chakra is extremely powerful. It's possible that this chakra could be harnessed in a way that can mimic the energy source of a lightsaber. Naruto, being the creative and adaptable ninja he is, would then figure out how to shape and control this new form of energy into a blade, much like a lightsaber. And he would surely use it to protect his friends and the Hidden Leaf Village.
Sasuke would likely be in the group. Despite their past differences, Naruto and Sasuke have a deep bond. Sasuke's skills would be invaluable to any group Naruto forms.
In fanfiction, Naruto creating Chidori could be possible through some creative plot devices. Maybe he was taught by Sasuke in an alternate universe where they teamed up earlier. Or perhaps he discovered a scroll that had the knowledge of Chidori and was able to learn it on his own with his determination and quick - learning ability.
One idea could be that Naruto creates his own village as a place of true peace and equality. He invites all those who have been marginalized or ostracized from other villages to join. His village would have unique training methods that combine all the ninja arts he has learned from different places, like the shadow clone jutsu combined with Sand Village's puppet techniques for a new form of combat.
One possible plot could be that Naruto, using his unique skills and leadership, unites the various ninja clans under his banner to form an empire. He might introduce new forms of governance that combine ninja traditions with more democratic ideals, ensuring equality among all citizens regardless of their ninja abilities.
