Well, the plot could start with Naruto being curious about a strange energy he senses. This energy turns out to be related to the 7 Wizarding Swords. He is then led to a portal that takes him to the world of the swords. There, he discovers that the swords are being misused by a dark wizard. Naruto decides to stop this. He teams up with some local resistance fighters. As he progresses, he discovers that the power of the swords can be harnessed in ways similar to his chakra. He uses this knowledge to his advantage, and in the end, he restores peace to the world of the 7 Wizarding Swords and returns to his own world with newfound powers and experiences.
The plot could be that Naruto is summoned to a realm where the 7 Wizarding Swords are of utmost importance. He is mistaken for a prophesied hero who is supposed to retrieve the swords and restore balance. So, he embarks on a journey to find each sword. Along the way, he uses his ninja skills like stealth and agility to overcome the guardians of the swords.
One possibility in this fanfiction could be Naruto somehow getting involved with the power of the 7 Wizarding Swords. Maybe he is transported to a world where these swords exist and has to learn to use their magic in his own unique ninja way. He could combine his chakra with the magic of the swords to create new and powerful attacks.
Well, it could be about Naruto coming back with two special swords. Maybe he got them during his time away on some new adventure. He might use these swords to fight stronger enemies in the ninja world, like some new evil organization that has emerged while he was gone.
It could also be a story where Harry has lost all hope. He has seen too much death and destruction in the wizarding world, from the war with Voldemort. He might think that the only way to end all the pain and suffering is to just end the wizarding world as it is. He could start by attacking the key institutions like Hogwarts and the Ministry of Magic.
Maybe Naruto is given the dual swords by a mysterious figure. As he starts using them, he realizes that they have a connection to an old prophecy. So he has to master the swords while also dealing with the various factions in the ninja world who either want to help him or stop him because of the prophecy.
In the fanfiction, Naruto finding dual swords could also change the dynamics of his relationships. His friends might be both impressed and a bit worried about his new - found weapons. And he might have to train hard to master the use of the swords, which could show a different side of his determination and growth as a ninja.
Naruto could potentially gain the power of mind - reading magic. This would be a huge advantage in both the wizarding war and in his interactions within Konoha. He could also gain the ability to transform into magical creatures, which would give him new forms of attack and defense. Another possibility is that he gains the power to nullify magic, which would make him a key player in the fight against wizards who use dark magic.
Well, it could be that Naruto's skills from his own world mix with the magic of the wizarding war. Maybe he uses his shadow clones in new and creative ways against magical foes. He might also learn some magic while in Konoha during the wizarding war, which would change the power dynamics in the village.
You could have a character who is an outsider to the Mist Village but is drawn to the power of the swords. They manage to steal one of the swords and then become a target for both the Mist ninja and other rogue elements in the Naruto world. This would create a lot of action and chase scenes as the character tries to evade capture while also learning to harness the sword's power.
Well, they could have the power to cut through any jutsu. Since Naruto has a lot of chakra, his swords might be able to channel that chakra and disrupt enemy techniques.
There could be a group of anti - ninja revolutionaries as the main antagonists. They see Naruto's return with the swords as a threat to their plan of overthrowing the existing ninja order. They try to take the swords from Naruto to use them as symbols of their new regime, believing that the power of the swords will help them convince other ninjas to join their cause.
