In a fanfic where Naruto uses haki, it could change his relationships with other characters too. For example, if he shows this new power, some characters might be in awe of him, while others might be jealous. His training to master haki could also lead to new interactions with mentors or allies who are familiar with this power. Also, his use of haki could potentially attract the attention of new enemies who are interested in this unique ability.
I think Conqueror's Haki would suit Naruto. He has that natural leadership and strong will, just like characters in One Piece who possess Conqueror's Haki. It would be a great addition to his existing confident and determined personality.
Dumbledore could be the one to teach Harry about Haki. Dumbledore, with his vast knowledge of magic and the unknown, might have come across Haki in his travels. He could recognize the signs of Haki in Harry and take it upon himself to guide Harry in understanding and controlling this new power. He would use his calm and wise approach, just like when he teaches Harry about other aspects of magic.
One possible plot could be that Harry discovers he has Haki during his time at Hogwarts. He first realizes it when facing a Dementor and his Haki flares up, scaring the Dementor away. Then, he starts to secretly train his Haki with the help of Hagrid, who has some knowledge of strange powers. As he gets better at it, he uses it to sense the true intentions of people around him, like when he suspects Snape. Eventually, he uses his Haki in the final battle against Voldemort, giving him an unexpected edge in the fight.
Hard to say for sure. It could be a blend of truth and imagination. Maybe some aspects are true, while others are made up to make the story more engaging.
Well, Mr Bates vs The Post Office is typically not based on real events. It might draw inspiration from various sources but is mainly a product of imagination and creative writing.
Maybe an ancient sage in Naruto's own world who has long - been in seclusion. This sage has knowledge of different power systems beyond just chakra. He notices Naruto's pure heart and strong will and decides to pass on his knowledge of haki to Naruto, believing that Naruto can use it for the greater good of the ninja world.
In 'naruto haki fanfic', Haki can change the Naruto universe by adding a new layer of power. For example, it can make battles more complex as characters now have to consider both chakra and Haki. It might also change the way characters interact with each other, as those with Haki could sense things differently.
