Well, in some fanfictions, Naruto might start learning the three - sword style after meeting a skilled swordsman. Maybe this swordsman sees potential in Naruto and decides to teach him the basics. For example, the swordsman could be from a hidden village that specializes in sword techniques.
He might infuse the sword with his chakra. Since Naruto has a large amount of chakra, he could make the Buster Sword glow with his unique chakra color. This would not only make the sword stronger but also give it new abilities. For instance, the chakra - infused sword could cut through stronger defenses or even repel enemy ninjutsu.
Sasuke is also a likely candidate. His natural talent with weapons and his quest for power could lead him to explore the Infinite Sword Style. He could use it to enhance his already formidable combat abilities and engage in more intense battles. He might also modify the style according to his own Sharingan - related skills.
One common element is the discovery of a special sword. It's often a powerful weapon with unique abilities or a connection to the past. For example, it might be a sword that was once used by a great ninja ancestor.
Perhaps a story where a young ninja, not originally proficient in swordsmanship, is forced to learn the two - sword style to avenge his family. He struggles at first but then finds an unexpected mentor who helps him master the style in a very unorthodox way. As he progresses, he uncovers a conspiracy related to the two - sword style that dates back to the founding of the ninja villages.
Well, it could be the part where the characters master new and unique sword techniques. Maybe when they combine their ninjutsu with sword skills in unexpected ways.
One unique storyline could be a character who discovers a hidden sword style passed down in their family. This style might have special powers like being able to cut through any jutsu. They then have to train hard to master it while also facing enemies who want to steal this powerful technique.
One great 'naruto legendary sword style fanfiction' is 'The Sword of the Uzumaki'. It focuses on Naruto discovering a hidden sword with a special power that has ties to his clan. The story is filled with intense battles as he masters the sword's unique style.
Sasuke would be an interesting character. He already has a proficiency with weapons and his Sharingan would give him an edge in quickly learning and adapting the one - sword style. His brooding nature also adds a certain depth to how he would approach mastering this new fighting style.
Often, an original character created specifically for the fanfiction can be really interesting. For example, a wandering swordsman who has mastered the two - sword style and has a mysterious past. He might have connections to an old war or a lost ninja art, and his interactions with the main Naruto characters add new dynamics to the story.
