Well, it could be that Naruto is on a special mission in a world that combines elements of his own and Kirito's. He might come across the swords as spoils of war or as a gift from a character who admires his skills. Fanfiction often plays with the idea of different universes colliding, so this scenario isn't too far - fetched.
One interesting storyline could be a crossover where Naruto and Sakura are transported to the world of Kirito and Asuna. They could team up with Kirito and Asuna to fight against a common enemy that combines the threats from both their worlds, like a powerful demon that has the ability to hack into the virtual world. This would lead to some really cool fight scenes with Naruto's ninjutsu, Sakura's strength, and Kirito and Asuna's sword skills all coming into play.
In a combined fight, Naruto might have an edge in terms of raw power. His Rasengan and other ninjutsu can cause massive destruction. However, Kirito's ability to quickly analyze his opponents and adapt his fighting style in the virtual world is not to be underestimated. Sakura could provide support with her medical skills and also hold her own in combat. Asuna's speed and precision with the sword could also be a game - changer. So, it really depends on how they team up and what strategies they use.
In such a fanfiction, Naruto might obtain all seven swords through a series of epic battles and adventures. Maybe he defeats the previous owners one by one in honorable combat and claims the swords as his trophies. Another possibility is that he stumbles upon a hidden treasure trove where all the swords are stored, and by some twist of fate, he becomes their rightful wielder.
Yes, there could be such fanfictions out there. The idea of Naruto being a fan of Kirito is an interesting crossover concept. In the world of fanfiction, authors often like to combine different universes and characters in unique ways. Naruto, coming from his own action - packed ninja world, could be fascinated by Kirito's adventures in the virtual world of Sword Art Online. It allows for some really creative storytelling possibilities.
Kirito did not buy two swords in the second season of the Sword and Sword Art Online. At the end of the first season, Kirito lost his first sword for some reason, but in the subsequent adventures, he obtained more weapons and equipment through interacting with other characters, including a second sword, a third sword, and so on. Therefore, Kirito did not buy two swords in the second season.
A common theme is the clash of two different worlds. Since Naruto is from a ninja - based world with chakra and Kirito is from a virtual gaming world, fanfictions often explore how these two different settings interact. For instance, how Kirito's gaming skills translate to the ninja world or how Naruto's ninja abilities would fare in a virtual world.
Naruto's ability to create multiple clones could be used as a distraction while Female Kirito makes a stealthy attack. For example, in a battle against a powerful foe, Naruto creates dozens of clones that surround the enemy. While the enemy is preoccupied with the clones, Female Kirito, with her quick reflexes and sword skills, can dash in and land a critical blow.
Well, in such a fanfiction, Kirito could teach Naruto about the technology in his world. Naruto, on the other hand, would show Kirito the importance of teamwork in a more physical and real - world sense. They could also have a friendly sparring match where Naruto uses his ninjutsu and Kirito uses his sword skills. It would be a really interesting clash of two very different fighting styles.
