Perhaps in this fanfic, Naruto's muteness makes him a target for discrimination at first. But then he uses his ninja skills in unique ways to prove his worth. He could start using his shadow clones to communicate different messages simultaneously, which would be a very Naruto - like creative solution.
One idea could be that Naruto has to find new ways to communicate his strong will and determination without speaking. Maybe he uses sign language that he invents himself, and his friends gradually learn to understand him. This could lead to some really heartwarming moments of connection.
A plot idea could be that Fem Naruto is mute because of a curse. As she tries to break this curse, she embarks on a journey filled with self - discovery. Along the way, she meets different characters who either help or hinder her progress. Her muteness makes her more observant, and she uses this to her advantage, learning secrets about the ninja world that others overlook.
One idea could be that Naruto is resurrected in a world where all his friends have forgotten him. He has to re - establish his relationships while also dealing with a new threat that emerged in his absence.
Maybe Naruto is adopted by a family outside of the Hidden Leaf village. This would force him to adapt to a new culture and way of life. He could learn different chakra - control techniques or even new forms of ninjutsu that are specific to that village. It could also create a conflict when the Hidden Leaf needs his help but he has loyalty to his new home as well.
One idea could be that Naruto discovers a mute girl in a hidden village during one of his travels. Shikamaru gets involved as Naruto tries to find a way to communicate with her. Maybe she has a unique power that only she can use, but because she's mute, she has trouble expressing it. Naruto's determination and Shikamaru's intelligence work together to help her out.
One plot idea could be that they discover their brotherhood early on and train together more closely. They might combine their unique abilities, like Naruto's Rasengan and Sasuke's Chidori, to create new and powerful jutsus. This could change the whole dynamic of the story, with them facing challenges as a united front instead of rivals.
One plot idea could be Naruto finding unique ways to communicate his ninja skills despite being mute. For example, he might use hand signals in a more complex way than normal. Since he's blind, he could develop an extraordinary sense of hearing to detect enemies. Another idea is that he forms a special bond with an animal that helps him 'see' the world around him, like a seeing - eye hawk or something.
A possible plot is that Naruto, mute as he is, discovers a new form of magic in the DxD universe that is related to silent communication. This could lead to him becoming a very powerful figure as he can communicate secretly with his allies during battles. Also, his backstory from Naruto could be intertwined with the DxD lore. For instance, his experience with loneliness in his own world could make him more empathetic towards the devils in DxD who are often misunderstood. He could then try to bridge the gap between different factions in the DxD world.
One idea could be that the mute prodigy has a unique form of ninjutsu that doesn't require speaking. Maybe they can use sign language to cast powerful jutsus. Another plot could involve the character being misunderstood because of their muteness, but gradually proving their worth. For example, in a mission, they use their silent skills to outwit the enemy.
One idea could be Naruto being mute in a crossover with the Harry Potter universe. He might communicate through magic signs or a special spell - created device. This could lead to him being misunderstood at first, but then his unique abilities, like his ninja skills, would shine through as he helps Hogwarts students in a new way.
Perhaps Naruto's dragon - summoning is linked to an ancient prophecy. In the story, as he starts to summon dragons, it sets off a chain of events where different ninja clans either try to help him or stop him, depending on how they interpret the prophecy. The dragons could also be guardians of some long - lost ninja secrets.
