"Naruto: My Wife Is Teruya" was a light novel written by the author, Movie King. The main character died in an accident and came to the Naruto world a thousand years ago. He fell in love with Teruya Ohki and embarked on a journey to find his wife. I hope you like this fairy's recommendation. Muah ~😗
In fanfiction, Naruto could be portrayed in various ways. He might be a character with new relationships and roles. Without reading the specific 'naruto father of yasaka fanfiction', it's hard to say exactly. But generally, he could be a father figure to Yasaka, which would likely involve a lot of character development and new storylines related to protecting, guiding, or having a special bond with Yasaka.
I think Hinata could be an ally. She has always been in love with Naruto and would not stand by while he is in danger from Dark Naruto. Additionally, Shikamaru is smart and strategic. He might see the threat of Dark Naruto to the village and decide to assist Naruto, using his intelligence to come up with battle plans.
Sasuke is one of Naruto's best friends. Their relationship is complex and forms a central part of the story. They start as rivals but gradually develop a deep bond.
Another possibility is Sakura. Although she has feelings for Sasuke in the original, in this fanfiction, the story could be rewritten so that she realizes her true connection with Naruto and they end up getting married at 12. Their dynamic would be quite different from the original, with Naruto having to prove himself in a new way to Sakura.
He could interact with Ruby. Naruto's energetic and positive nature would contrast well with Ruby's enthusiasm for being a huntress. They could learn from each other's combat styles, like Naruto showing Ruby some of his acrobatic ninja moves and Ruby teaching Naruto about using a scythe.
He could interact with Luffy. They both have a strong sense of justice and a love for adventure. Their meeting would be really interesting as they could exchange stories about their different worlds and fight side by side against the common enemies in Dressrosa.
Definitely Ruby. She's the main character in RWBY, and Naruto would be drawn to her positive attitude and determination. They could learn a lot from each other. Naruto could teach her about the importance of never giving up like he did in his own journey, and Ruby could show Naruto how to use Dust.
Sasuke could potentially be an ally. Even though they've had their differences, Sasuke might understand Naruto's situation and decide to help him. Also, some of the Jinchuriki he's met before could be allies. They might see Naruto as one of their own and support him during his exile.
