In this fanfiction, aside from Naruto, we could have Mio. Mio has a very special zanpakuto that can manipulate time on a small scale. She's mysterious and Naruto is intrigued by her. Another character could be Nami, whose zanpakuto has the power to create illusions. She uses it to play pranks on Naruto at first but later becomes very attached to him. And there's also Sora, a girl with a zanpakuto that can create portals. She helps Naruto explore different parts of the zanpakuto world.
Well, there could be a character named Yuki. She has an ice - type zanpakuto and she's very reserved but warms up to Naruto. Then there's Rina, who has a wind - based zanpakuto and is really energetic. She would be constantly challenging Naruto to friendly spars. And also, Aiko, a girl with a healing - type zanpakuto. She would be the one taking care of Naruto when he gets injured during his adventures in this new world of zanpakuto.
Sakura could be one of the main characters. She might be part of the harem and her reaction to Naruto leaving could be a significant part of the story. Maybe she tries to bring him back or has her own journey of growth while he's away.
In a Naruto finds a zanpakuto fanfiction, it could lead to some really interesting crossovers. Naruto might initially be confused by the strange weapon. He could try to use it in his own unique way, perhaps combining his chakra with the zanpakuto's power. Maybe he'd seek out someone to teach him about it, like if he somehow ended up in the Bleach universe and found Ichigo to help him understand the zanpakuto better.
Well, in such a fanfiction, the plot could be that Naruto somehow stumbles upon a world where zanpakuto exist. He might start by being confused about these strange swords. Then, as he meets the female characters associated with the zanpakuto (forming the harem), he could learn about their powers and the bond they share with their weapons. Maybe Naruto would try to incorporate their fighting styles into his own jutsu, and along the way, form deep emotional connections with the girls in the harem.
Well, Ino could be one of the potential characters. She is a strong - willed and confident girl who might be attracted to Naruto's positive attitude. Another could be Tenten. She respects strong ninja skills, and Naruto's growth as a ninja might catch her eye. Also, Temari could be a part of it. Given her own strong personality, she might find Naruto's determination and unique charm appealing.
Perhaps there could be a storm - wizard or a shaman who adopts Naruto. This character would have deep knowledge of storm - related powers and would be the one to guide Naruto in his new journey.
Sasuke could be one of the main characters. He might be the one who comes across Naruto in his boxers and has a very typical Sasuke - like reaction, which could be a mix of annoyance and amusement. His presence could add some tension as well as some banter to the story.
One character could be Jiraiya. He could have known something about Naruto's true heritage all along and be the one to finally reveal it to Naruto. From the Greek side, Triton, Poseidon's son in mythology, could be a character. He could either be a rival or an ally to Naruto. In the ninja world, Shikamaru might be involved. His intelligence could be used to help Naruto understand and strategize with his new powers, especially when dealing with any threats that come his way because of his connection to Poseidon.

Sakura could be one. She has a long - standing relationship with Naruto and might be part of the harem. Also, Hinata. Given her feelings for Naruto, she could be drawn into this situation. Shikamaru might also be included, not in a romantic way for Naruto but as a friend who gets involved in the group dynamic. And Kiba, with his brash personality, could add an interesting element to the group.
