Yes, it could mean that. In fanfiction, original characters (OCs) often use elements from the existing lore, like the powerful Shinso zanpakuto. Writers might create scenarios where their OCs wield such a weapon for various reasons, like to make the OC stand out or to fit into a particular plot within the fan - created story.
Power growth is a common theme. Since Ichigo has two zanpakuto, fan fictions often focus on how he becomes more powerful. For example, he might learn new techniques.
There are some really interesting ones out there. You can start by looking on fan - fiction websites like FanFiction.net or Archive of Our Own. Just search for the relevant tags like 'Naruto', 'Bleach', 'Kyuubi', and 'Zanpakuto'. Some stories might combine the elements in unique ways, such as a character from Naruto getting a Zanpakuto - like weapon with the power of the Kyuubi.
There's a fan fiction called 'Ichigo's Twin Zanpakuto Adventure'. In this story, Ichigo discovers that his two zanpakuto have unique abilities that are intertwined. The author does a great job of showing Ichigo's growth as he tries to understand and use these powers. For example, he has to face off against powerful enemies and learn to combine the powers of the two swords in new and unexpected ways.
At first, Naruto would be clumsy with it. He has no prior experience with Zanpakuto. But his determination would drive him to practice. He'd study how to hold it properly, how to swing it effectively. Maybe he'd even talk to it like he does with his friends, trying to understand its spirit if it has one.
Perhaps they are a gift from a mysterious and powerful being who sees Naruto's potential. This being could be observing the Naruto - verse from afar and decides that Naruto is the perfect candidate to wield dual zanpakuto. The being may have their own reasons, like wanting to see how Naruto will use the powers of two zanpakuto to change the balance in his world.
Naruto could have a Zanpakuto with the ability to create illusions of hope. Given his character, it would make sense for his Zanpakuto to have an ability that gives his opponents a vision of a better future if they stop fighting. This would be a non - violent way of ending battles, which aligns with Naruto's ideology. Another possible ability could be to transform his chakra into a tangible form that can be used to either heal or boost the strength of his allies. It would be like his chakra is being channeled through the Zanpakuto in a more controlled and versatile way.
Maybe it's a mysterious traveler from a far - off land. This traveler recognizes Naruto's potential and strength of character and gives him the three zanpakuto as a means to help Naruto protect his village and the people he loves.
Maybe a zanpakuto with the power to heal. Naruto is all about protecting his friends and village. So a zanpakuto that can heal wounds during battle would be very useful. It could also have a secondary ability to boost the chakra of his allies. This would fit with Naruto's selfless nature.
One of the zanpakuto in the 'naruto has three zanpakuto fanfiction' could be a traditional - looking katana with a simple design but has the power to absorb the opponent's chakra on contact. The second zanpakuto might be a larger, two - handed sword with a jagged edge that can break through defenses by vibrating at a high frequency. The third zanpakuto could be a short - sword with the ability to teleport the wielder a short distance when swung in a certain way.
